We’ve put collectively a list of the preferred kinds of heavy tools for construction. Construction projects typically rely on a number of forms of heavy gear to get the job accomplished in a well timed, protected, and cost-effective manner. Depending on the dimensions and scope of the construction project, you’ll probably need to make use of no much less than certainly one of these pieces of heavy development equipment.
17 Types of Heavy Equipment and Their Uses
From excavators and dump vehicles to concrete pumps and compactors, we’ve listed the most typical forms of development heavy tools. Click the hyperlink to jump to the kind of gear you’re excited about learning more about.
Excavators
Excavators (hydraulic) are heavy development gear consisting of a growth, dipper or stick, bucket, and cab on a rotating platform known as the “house”. The home sits atop an undercarriage with tracks or wheels. They are a natural development from the steam shovels and often mistakenly called power shovels.
All motion and capabilities of a hydraulic excavator are achieved by way of the utilization of hydraulic fluid, hydraulic cylinders, and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is essentially different from cable-operated excavators which use winches and steel ropes to perform the actions.
Excavators are additionally referred to as diggers, mechanical shovels, or 360-degree excavators. typically abbreviated merely to “360”. Tracked excavators are typically referred to as “trackhoes” by analogy to the backhoe.
Excavators are used in some ways:
* Digging of trenches, holes, foundations
* Material handling
* Brush chopping with a hydraulic noticed and mower attachments
* Forestry work
* Forestry mulching
* Construction
* Demolition with a hydraulic claw, cutter and breaker attachments
* General grading/landscaping
* Mining, particularly, but not only open-pit mining
* River dredging
* Driving piles, at the side of a pile driver
* Drilling shafts for footings and rock blasting, by use of an auger or hydraulic drill attachment
* Snow removal with snowplow and snow blower attachments
Loaders
A loader is a heavy equipment machine used in development to maneuver aside or load materials such as asphalt, demolition debris, dirt, snow, feed, gravel, logs, raw minerals, recycled materials, rock, sand, woodchips, and so forth. into or onto one other kind of equipment corresponding to a dump truck, conveyor belt, feed-hopper, or railroad car.
There are many kinds of loader, which, depending on design and application, are referred to as by varied names, together with:
* Bucket Loader
* Front Loader
* Front-end Loader
* Payloader
* Scoop
* Shovel
* Skip Loader
* Wheel Loader
* Skid-steer
* Tractor Front Loader
* Compact Front End Loader
* Swing Loader
Paving Machines
A paver is also recognized as a paver finisher, asphalt finisher, paving machine, is a piece of development equipment used to put asphalt on roads, bridges, parking lots and other such places. It lays the asphalt flat and offers minor compaction earlier than it’s compacted by a curler.
The asphalt paver was developed by Barber Greene Co., initially manufactured materials dealing with methods. In 1929 the Chicago Testing Laboratory approached them to use their materials loaders to assemble asphalt roads.
Large freeways are sometimes paved with concrete and that is done utilizing a slipform paver. Trucks dump loads of readymix concrete in heaps along in entrance of this machine and then the slipform paver spreads the concrete out and ranges it off using a screed.
Backhoes
A backhoe (also referred to as a rear actor or back actor) is a kind of excavating equipment, or digger, consisting of a digging bucket on the end of a two-part articulated arm. It is typically mounted on the again of a tractor or front loader, the latter forming a “backhoe loader”.
The part of the arm closest to the vehicle is identified as the growth, while the part that carries the bucket is named the dipper or dipper-stick, both phrases derived from steam shovels. The increase is mostly attached to the vehicle by way of a pivot generally known as the king-post, which permits the arm to pivot left and proper, normally via a total of a hundred and eighty to 200 degrees.
Bulldozers
Typically, bulldozers are giant and powerful tracked heavy tools. The tracks give them wonderful ground holding capability and mobility via very rough terrain. Wide tracks help distribute the bulldozer’s weight over a large area (decreasing floor pressure), thus stopping it from sinking in sandy or muddy floor. Extra-wide tracks are often known as swamp tracks or LGP (low ground pressure) tracks.
Bulldozers have transmission systems designed to take advantage of the monitor system and provide excellent tractive pressure. Because of those attributes, bulldozers are sometimes used in
* Road Building
* Construction
* Mining
* Forestry
* Land Clearing
* Infrastructure Development
and another tasks requiring highly cell, powerful, and steady earth-moving equipment.
Another sort of bulldozer is the wheeled bulldozer, which generally has 4 wheels pushed by a 4-wheel-drive system and has a hydraulic, articulated steering system. The blade is mounted ahead of the articulation joint and is hydraulically actuated.
The bulldozer’s main instruments are the blade and the ripper.
Blade
The bulldozer blade is a heavy metallic plate on the entrance of the tractor, used to push objects, and shove sand, soil, debris, and typically snow. Dozer blades normally come in three varieties:
1. A straight blade (“S blade”) which is brief and has no lateral curve and no facet wings and can be utilized for nice grading.
2. A common blade (“U blade”) which is tall and very curved, and has giant facet wings to carry more material.
three. An “S-U” (semi-U) combination blade which is shorter, has much less curvature, and smaller side wings. This blade is typically used for pushing piles of enormous rocks, similar to at a quarry.
Blades may be fitted straight throughout the frame, or at an angle, typically using further ’tilt cylinders’ to range the angle whereas transferring. The backside edge of the blade could be sharpened, e.g. to cut tree stumps.
Ripper
The ripper is the long claw-like device on the again of the bulldozer. Rippers can come as a single shank/giant ripper, or in teams of two or extra multi shank rippers.
Usually, a single shank is most well-liked for heavy ripping. The ripper shank is fitted with a replaceable tungsten steel alloy tip, referred to as a ‘boot’. Ripping rock breaks the ground floor rock or pavement into small rubble easy to deal with and transport, which may then be eliminated so grading can happen.
With agricultural ripping, a farmer breaks up rocky or very onerous earth such as podzol hardpan, which is in any other case unploughable, so as to farm it.
The word “bulldozer” is typically used inaccurately for other similar development vehicles corresponding to a big entrance loader.
Dump Trucks
A dump truck, also called a dumper truck or tipper truck, is used for taking dumps corresponding to sand, gravel, or demolition waste for building. A typical dump truck is equipped with an open-box mattress, which is hinged on the rear and geared up with hydraulic rams to raise the front, allowing the fabric within the bed to be deposited (“dumped”) on the ground behind the truck on the site of supply

Types of Dump Trucks
There are several forms of dump trucks for just about any utility you probably can think of. Below is a breakdown of the several varieties of dump vans.
STANDARD DUMP TRUCK
A commonplace dump truck is a truck chassis with a dump body mounted to the frame. The mattress is raised by a vertical hydraulic ram mounted underneath the entrance of the physique or a horizontal hydraulic ram and lever association between the body rails, and the back of the bed is hinged at the again of the truck.
The tailgate can be configured to swing up on top hinges (and typically additionally to fold down on lower hinges) or it can be configured within the “High Lift Tailgate” format whereby pneumatic rams carry the gate open and up above the dump physique.
SEMI-TRAILER END DUMP TRUCK
A semi finish dump is a tractor-trailer combination whereby the trailer itself accommodates the hydraulic hoist. In the US a typical semi end dump has a 3-axle tractor pulling a 2-axle trailer with dual tires.
The key benefit of a semi finish dump is a large payload. A key drawback is that they are very unstable when raised within the dumping position limiting their use in many functions the place the dumping location is uneven or off stage.
TRANSFER DUMP TRUCK
A switch dump truck is a standard dump truck pulling a separate trailer with a movable cargo container, which can be loaded with development mixture, gravel, sand, asphalt, klinkers, snow, wood chips, triple mix, etc.
The second mixture container on the trailer (“B” box) is powered by an electric motor, a pneumatic motor or a hydraulic line. It rolls on small wheels, riding on rails from the trailer’s body into the empty primary dump container (“A” box). This maximizes payload capacity with out sacrificing the maneuverability of the standard dump truck. Transfer dump vans are usually seen in the western United States as a end result of peculiar weight restrictions on highways there.
TRUCK AND PUP
A truck and pup are very related to a switch dump. It consists of a standard dump truck pulling a dump trailer. The pup trailer, unlike the switch, has its personal hydraulic ram and is able to self-unloading.
SUPER DUMP TRUCK
A super dump is a straight dump truck equipped with a trailing axle, a liftable, load-bearing axle rated as excessive as 13,000 kilos. Trailing 11 to 13 toes behind the rear tandem, the trailing axle stretches the outer “bridge” measurement, the space between the first and final axles, to the utmost general length allowed.
This increases the gross weight allowed beneath the federal bridge formulation, which sets standards for truck measurement and weight. Depending on the car length and axle configuration, Superdumps may be rated as high as eighty,000 kilos. GVW and carry 26 brief tons of payload or more.
When the truck is empty or prepared to offload, the trailing axle toggles up off the highway surface on two hydraulic arms to clear the rear of the car.
SEMI-TRAILER BOTTOM DUMP TRUCK
A semi backside dump or stomach dump is a 3-axle tractor pulling a 2-axle trailer with a clamshell-type dump gate within the stomach of the trailer.
The key advantage of a semi bottom dump is its ability to lay materials in a windrow, a linear heap. In addition, a semi bottom dump is maneuverable in reverse, unlike the double and triple trailer configurations described below.
These trailers could also be found either of the windrow sort proven in the photo or possibly of the cross unfold sort, with the gate opening front to rear as a substitute of left and right. The cross unfold type gate will truly unfold the cereal grains pretty and evenly from the width of the trailer.
By comparability, the windrow sort gate leaves a pile in the middle. The cross unfold sort gate, then again, tends to jam and should not work very nicely with coarse materials.
DOUBLE & TRIPLE TRAILER BOTTOM DUMP TRUCK
Double and triple backside dumps consist of a 2-axle tractor pulling one single-axle semi-trailer and an extra full trailer (or two full trailers in the case of triples). These dump vehicles permit the motive force to put materials in windrows with out leaving the cab or stopping the truck.
The primary disadvantage is the difficulty in backing double and triple models.
SIDE DUMP TRUCK
A facet dump truck also referred to as an SDT consists of a 3-axle tractor pulling a 2-axle semi-trailer. It has hydraulic rams that tilt the dump physique onto its facet, spilling the material to both the left or right facet of the trailer. The key advantages of the side dump are that it permits rapid unloading and might carry extra weight.
In addition, it is almost proof against upset or tipping over whereas dumping, unlike the semi finish dumps that are very prone to tipping over. It is, however, highly likely that a facet dump trailer will tip over if dumping is stopped prematurely.
Also, when dumping free materials or cobble sized stone, the facet dump can turn out to be caught if the pile turns into extensive sufficient to cover too much of the trailer’s wheels.
Trailers that dump at the acceptable angle, 50° for example, keep away from the problem of the dumped load fouling the path of the trailer wheels by dumping their masses additional to the side of the truck, in some circumstances leaving sufficient clearance to walk between the dumped load and the trailer.
WINTER SERVICE VEHICLES
Many winter service automobiles are primarily based on dump vehicles, to allow the location of ballast to weigh the truck down or to hold sodium or calcium chloride salts for spreading on snow and ice-covered surfaces. Plowing is a severe service and wishes heavy-duty trucks.
ROLL-OFF TRUCKS
A Roll-off has a hoist and subframe, but no one, it carries removable containers. The container is loaded on the ground, then pulled onto the back of the truck with a winch and cable. The truck goes to the dumpsite after it has been dumped the empty container is taken and positioned to be loaded or stored.
The hoist is raised and the container slides down the subframe so the rear is on the bottom. The container has rollers on the rear and can be moved forward or back till the entrance of it’s lowered onto the ground.
The containers are often open-topped bins used for rubble and constructing debris, however rubbish compactor containers are also carried. A newer hook-lift system does the identical job, however lifts/lower and dumps the container with a increase association as an alternative of a cable and hoist.
OFF-HIGHWAY DUMP TRUCKS
Off-highway dump trucks are heavy building gear and share little resemblance to freeway dump trucks. Bigger off-highway dump vans are used strictly off-road for mining and heavy filth hauling jobs.
There are two major types: a inflexible body and an articulating frame. The time period “dump” truck just isn’t typically utilized by the mining industry, or by the producers that construct these machines. The more applicable U.S. term for this strictly off-road car is “haul truck”.
HAUL TRUCK
Haul trucks are utilized in large surface mines and quarries. They have a inflexible body and standard steering with the drive on the rear wheel. As of late 2013, the biggest ever production haul truck is the 450 metric ton BelAZ 75710, adopted by the Liebherr T 282B, the Bucyrus MT6300AC, and the Caterpillar 797F, which each have payload capacities of up to four hundred brief tons.
Most giant measurement haul trucks make use of Diesel-electric powertrains, utilizing the Diesel engine to drive an AC alternator or DC generator that sends electric power to electrical motors at each rear wheel. The Caterpillar 797 is exclusive for its dimension, as it employs a Diesel engine to energy a mechanical powertrain, typical of most road-going autos and middleman size haul trucks.
Other major producers of haul vehicles include SANY, XCMG, Hitachi, Komatsu, DAC, Terex, and BelAZ.
ARTICULATED HAULER
An articulated dumper is an all-wheel-drive, off-road dump truck. It has a hinge between the cab and the dump box but is distinct from a semi-trailer truck in that the facility unit is a everlasting fixture, not a separable car.
Steering is completed through hydraulic cylinders that pivot the whole tractor in relation to the trailer, quite than a rack and pinion steering on the front axle as in a traditional dump truck.
By this manner of steering, the trailer’s wheels comply with the identical path as the entrance wheels. Together with all-wheel drive and low center of gravity, it’s extremely adaptable to rough terrain. Major manufacturers embrace Volvo CE, Terex, John Deere, and Caterpillar.
Trenchers
A trencher is a chunk of development gear used to dig trenches, especially for laying pipes or electrical cables, for putting in drainage, or in preparation for trench warfare. Trenchers may range in dimension from walk-behind models to attachments for a skid loader or tractor, to very heavy tracked heavy gear.
5 Types of Trenchers
1. Wheel Trencher – A wheel trencher or rockwheel is composed of a toothed steel wheel. It is cheaper to function and keep than chain-type trenchers. It can work in onerous or gentle soils, both homogeneous – compact rocks, silts, sands, or heterogeneous – split or broken rock, alluvia, moraines.
2. Chain Trencher – A chain trencher cuts with a digging chain or belt that is pushed round a rounded steel body, or growth. It resembles an enormous chainsaw. This type of trencher can reduce floor that’s too hard to chop with a bucket-type excavator and can even minimize narrow and deep trenches.
3. Micro Trencher – A micro trencher is a “small rockwheel” specifically designed for work in city areas. It is fitted with a slicing wheel that cuts a microtrench with smaller dimensions than can be achieved with typical trench digging equipment.
4. Portable Trencher – Landscapers and garden care specialists might use a portable trencher to put in panorama edging and irrigation strains. These machines are light-weight (around 200 pounds) and are easily maneuverable in comparability with different types of trenchers. The chopping implement could additionally be a sequence or a blade just like a rotary lawnmower blade oriented in order that it rotates in a vertical airplane.
5. Tractor-Mount Trencher – A tractor-mount trencher is a trenching device which needs a creeping gear tractor to function. This sort of trencher is one other type of chain trencher. The tractor ought to be able to go as slowly as the trencher’s trenching speed.
Compactors
A compactor in construction has three main varieties:
1. The Plate
2. The Rammer
three. The Road Roller
The plate compactor, vibrating plate, or tamper, has a large vibrating baseplate and is suited to making a stage grade.
The rammer compactor has a smaller foot. The rammer, or trench rammer, is especially used to compact the backfill in narrow trenches for water or gas provide pipes, etc… Road rollers may have vibrating rollers.
The roller type compactors are used for compacting crushed rock as the base layer beneath concrete or stone foundations or slabs.
In plates and rollers, the vibration is offered by quickly rotating eccentric lots. In smaller plates, the vibration causes a bent to maneuver forwards, whereas some larger plates are provided with directional control.
In the rammer, the foot is mounted on a sleeve that slides vertically within the leg. Inside the sleeve, a piston is driven up and down by the engine by way of a reduction gear, crank, and connecting rod. Substantial coil springs above and beneath the piston connect it to the sliding sleeve.
The connection between the sleeve and foot is a small angle in order that the entire rammer leans away from the operator. The vibrating movement is due to this fact barely off the vertical, and this offers the rammer a bent to ‘walk’ forwards. The sliding joint within the leg is protected by versatile bellows.
Graders
A grader, additionally generally referred to as a road grader or a motor grader, is a development machine with an extended blade used to create a flat surface through the grading course of. Although the earliest models had been towed behind horses or other powered tools, most fashionable graders comprise an engine, so are known, technically erroneously, as “motor graders”.
Typical fashions have three axles, with the engine and cab situated above the rear axles at one finish of the car and a 3rd axle on the front finish of the car, with the blade in between.
Most motor graders drive the rear axles in tandem, but some also add front-wheel drive to improve grading capability. Many graders also have optional attachments for the rear of the machine which can be ripper, scarifier, blade, or compactor.
For snowplowing and a few filth grading operations, a facet blade can be mounted. Some development personnel refers back to the whole machine as “the blade”. Capacities vary from a blade width of 8 ft to 24 ft and engines from 125 hp–500 hp.
Certain graders can function a number of attachments, or be designed for specialized duties like underground mining.

Telehandlers (Telescopic Handler)
A telescopic handler, additionally referred to as a telehandler, teleporter, attain forklift or growth lift is a machine extensively used in agriculture and business. It is considerably like a forklift but has a boom (Telescopic cylinder), making it more a crane than a forklift, with the increased versatility of a single telescopic or articulating boom that may lengthen forwards and upwards from the car.
At the top of the growth the operator can match certainly one of a quantity of attachments, similar to a bucket, pallet forks, muck grab, or winch. Telehandlers are generally called cherry pickers in North America, as that name can discuss with any truck or heavy equipment that has such a increase.
In trade, the most typical attachment for a telehandler is pallet forks and the commonest application is to move loads to and from locations unreachable for a traditional forklift.
For instance, telehandlers have the power to take away palletized cargo from within a trailer and to position loads on rooftops and other excessive places. The latter utility would in any other case require a crane, which isn’t all the time practical or time-efficient.
In agriculture the most common attachment for a telehandler is a bucket or bucket grab, again the most typical application is to maneuver masses to and from locations unreachable for a ‘conventional machine’ which on this case is a wheeled loader or backhoe loader.
Backhoe Loaders
A backhoe loader, additionally known as a loader backhoe, digger in layman’s phrases, or colloquially shortened to backhoe inside the business, is a heavy equipment car that consists of a tractor-like unit fitted with a loader-style shovel/bucket on the entrance and a backhoe on the again.
Due to its relatively small size and versatility, backhoe loaders are very common in urban engineering and small construction tasks similar to constructing a small house, fixing city roads, and so on.. as well as creating countries.
This type of machine is similar to and derived from what’s now often known as a TLB (Tractor-Loader-Backhoe), which is to say, an agricultural tractor fitted with a entrance loader and rear backhoe attachment.
Tower Cranes
A crane is a kind of machine, usually geared up with a hoist rope, wire ropes or chains, and sheaves, that can be utilized both to raise and decrease supplies and to maneuver them horizontally.
It is especially used for lifting heavy things and transporting them to other places.
The device uses a quantity of easy machines to create mechanical advantage and thus move hundreds past the traditional capability of a human.
Cranes are generally employed in the transport business for the loading and unloading of freight, in the construction industry for the movement of materials, and within the manufacturing business for the assembling of heavy tools.
Tower cranes are a contemporary form of stability crane that consist of the same primary parts. Fixed to the ground on a concrete slab and generally attached to the sides of constructions, tower cranes typically give the most effective combination of top and lifting capability and are used within the construction of tall buildings.
The base is then attached to the mast which supplies the crane its peak. Further, the mast is hooked up to the slewing unit (gear and motor) that allows the crane to rotate. On prime of the slewing unit, there are three main parts that are: the lengthy horizontal jib (working arm), shorter counter-jib, and the operator’s cab.
Feller Bunchers
A feller buncher is a sort of harvester utilized in logging. It is a motorcar with an attachment that can quickly collect and reduce a tree earlier than felling it.
Feller is a conventional name for someone who cuts down timber, and bunching is the skidding and assembly of two or extra trees.
A feller buncher performs each of these harvesting capabilities and consists of a regular heavy tools base with a tree-grabbing system furnished with a chain-saw, circular saw or a shear—a pinching system designed to cut small bushes off on the base. The machine then locations the reduce tree on a stack suitable for a skidder, forwarder, or yarder for transport to further processing similar to delimbing, bucking, loading, or chipping.
Some wheeled feller bunchers lack an articulated arm and should drive close to a tree to understand it.
Dragline Excavator
A dragline excavator is a piece of heavy gear used in civil engineering and surface mining.
Draglines fall into two broad categories: those which are based on commonplace, lifting cranes, and the heavy units which should be built on-site. Most crawler cranes, with an added winch drum on the entrance, can act as a dragline. These units (like other cranes) are designed to be dismantled and transported over the highway on flatbed trailers.
Draglines used in civil engineering are almost always of this smaller, crane kind. These are used for street, port building, pond, and canal dredging, and as pile driving rigs. These varieties are built by crane producers such as Link-Belt and Hyster.
The a lot larger sort which is built on website is often utilized in strip-mining operations to remove overburden above coal and extra just lately for oil sands mining. The largest heavy draglines are among the many largest cell land machines ever constructed. The smallest and most common of the heavy kind weigh around 8,000 tons whereas the biggest built weighed around thirteen,000 tons.
A dragline bucket system consists of a giant bucket that’s suspended from a boom (a massive truss-like structure) with wire ropes. The bucket is maneuvered by means of a quantity of ropes and chains. The hoist rope, powered by large diesel or electric motors, helps the bucket and hoist-coupler meeting from the boom. The dragrope is used to draw the bucket assembly horizontally. By skillful maneuver of the hoist and the dragropes the bucket is controlled for varied operations. A schematic of a large dragline bucket system is shown under.
Wheel Tractor Scraper
In civil engineering, a wheel tractor-scraper is a chunk of heavy equipment used for earthmoving. The rear part of the scraper has a vertically moveable hopper with a sharp horizontal entrance edge which could be raised or lowered. The front edge cuts into the soil, like a carpenter’s plane chopping wood, and fills the hopper. When the hopper is full it is raised, closed, and the scraper can transport its load to the fill space where it is dumped. With a kind called an ‘elevating scraper,’ a conveyor belt strikes materials from the cutting edge into the hopper.
Scraper Configurations
* Open bowl: normally requires a push-cat (bulldozer or similar) to assist in loading.
* Elevating scraper: self-loading as it makes use of an elevator to load materials; requires no push-cat.
* Tandem scrapers: separate tractor and scraper engines provide higher traction in steep or slippery areas; a push cat is required except when loading loose supplies.
* Tandem Push-Pull: concentrates the combined horsepower of two such machines onto one cutting edge. The push-pull attachment permits two individual scrapers to behave as a self-loading system, usually loading each machines in lower than a minute, one after the other.
* Auger makes use of vertically mounted auger in the bowl to pull material upwards.
* Pull type scraper: uses an agricultural tractor, articulated dump truck, or bulldozer to pull. Pull type scrapers can be utilized individually or two or three units may be pulled behind a single tractor.
Pile Driving Machines
A pile driver is a tool used to drive piles into the soil to supply foundation support for buildings or different structures. The term can be utilized in reference to members of the development crew that works with pile-driving rigs.
One kind of pile driver uses a weight placed between guides in order that it may possibly slide vertically. It is positioned above a pile. The weight is raised, which may involve the utilization of hydraulics, steam, diesel, or guide labor. When the load reaches its highest point it’s launched, and hits the pile, driving it into the bottom.
Types of Pile Driving Machines
* Diesel Hammer
* Vertical Travel Lead Systems
* Hydraulic Hammer
* Hydraulic Press-in
* Vibratory pile driver/extractor
* Piling rig
Piling Rigs Categories
1. Small-sized – torque is around 60–100 kN m, engine power 108 kW, drilling diameter zero.5–1.2 m, drilling depth 40 m, total quality forty t.
2. Middle-sized – torque is round 120–180 kN m, engine power 125–200 kW, drilling diameter 0.8–1.8 m, drilling depth 60 m, whole quality 42–65 t.
3. Large-sized – torque is round 240 kN m, engine energy 300 kW, drilling diameter 1–2.5 m, drilling depth 80 m, whole quality one hundred t.
Concrete Pumps
A concrete pump is a machine used for transferring liquid concrete by pumping. There are two kinds of concrete pumps.
The first type of concrete pump is hooked up to a truck or longer models are on semi-trailers. It is called a increase concrete pump as a result of it makes use of a remote-controlled articulating robotic arm (called a boom) to put concrete precisely. Boom pumps are used on a lot of the larger construction projects as they are able to pumping at very excessive volumes and because of the labor-saving nature of the placing growth. They are a revolutionary alternative to line-concrete pumps.
The second main kind of concrete pump is both mounted on a truck or positioned on a trailer, and it’s generally referred to as a line pump or trailer-mounted concrete pump. This pump requires metal or flexible concrete putting hoses to be manually hooked up to the outlet of the machine. Those hoses are linked collectively and lead to wherever the concrete must be placed.
The length of the hoses varies usually 10’, 12.5’, 25’ and 50’ depending on the diameter of the hose. Line pumps usually pump concrete at lower volumes than growth pumps and are used for smaller volume concrete inserting functions such as swimming swimming pools, sidewalks, and single-family house concrete slabs and most ground slabs.
There are also skid mounted and rail mounted concrete pumps, but these are uncommon and only used on specialised job sites corresponding to mines and tunnels.
