Complete Guide for Dump Trucks
What is a Dump Truck
A dump truck, also known as a dumper truck or tipper truck, is used for taking finer material such as sand, gravel, or demolition waste for construction. One is typically equipped with an open-box bed, which is hinged at the rear and equipped with hydraulic rams to lift the front, allowing the material in the bed to be deposited (“dumped”) on the ground behind the truck at the site of delivery.
This article will go over the different types of dump trucks, dump truck brands, how to buy a dump truck, and how to finance one.
There are several types of dump trucks for pretty much any application you can think of. Below is a breakdown of the different types.
Standard Dump Truck
A standard dump truck is a truck chassis with a dump body mounted to the frame. The bed is raised by a vertical hydraulic ram mounted under the front of the body or a horizontal hydraulic ram and lever arrangement between the frame rails, and the back of the bed is hinged at the back of the truck.
The tailgate can be configured to swing up on top hinges (and sometimes also to fold down on lower hinges) or it can be configured in the “High Lift Tailgate” format wherein pneumatic rams lift the gate open and up above the dump body.
Semi-Trailer End Dump Truck
A semi end dump is a tractor-trailer combination wherein the trailer itself contains 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 advantage of a semi end dump is a large payload. A key disadvantage is that they are very unstable when raised in the dumping position limiting their use in many applications where the dumping location is uneven or off level.
Transfer Dump Truck
A transfer dump truck is a standard dump truck pulling a separate trailer with a movable cargo container, which can also be loaded with construction aggregate, gravel, sand, asphalt, klinkers, snow, wood chips, triple mix, etc.
The second aggregate 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 frame into the empty main dump container (“A” box). This maximizes payload capacity without sacrificing the maneuverability of the standard dump truck. Transfer dump trucks are typically seen in the western United States due to the peculiar weight restrictions on highways there.
Truck and Pup
A truck and pup are very similar to a transfer dump. It consists of a standard dump truck pulling a dump trailer. The pup trailer, unlike the transfer, has its own hydraulic ram and is capable of 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 high as 13,000 pounds. Trailing 11 to 13 feet behind the rear tandem, the trailing axle stretches the outer “bridge” measurement, the distance between the first and last axles, to the maximum overall length allowed.
This increases the gross weight allowed under the federal bridge formula, which sets standards for truck size and weight. Depending on the vehicle length and axle configuration, Superdumps can be rated as high as 80,000 pounds. GVW and carry 26 short tons of payload or more.
When the truck is empty or ready to offload, the trailing axle toggles up off the road surface on two hydraulic arms to clear the rear of the vehicle.
A semi bottom dump or belly dump is a 3-axle tractor pulling a 2-axle trailer with a clamshell type dump gate in the belly of the trailer.
The key advantage of a semi bottom dump is its ability to lay material 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 may be found either of the windrow type shown in the photo or maybe of the cross spread type, with the gate opening front to rear instead of left and right. The cross spread type gate will actually spread the cereal grains fairly and evenly from the width of the trailer.
By comparison, the windrow type gate leaves a pile in the middle. The cross spread type gate, on the other hand, tends to jam and may not work very well with coarse materials.
Double & Triple Trailer Bottom Dump Truck
Double and triple bottom dumps consist of a 2-axle tractor pulling one single-axle semi-trailer and an additional full trailer (or two full trailers in the case of triples). These dump trucks allow the driver to lay material in windrows without leaving the cab or stopping the truck.
The main disadvantage is the difficulty in backing double and triple units.
Side Dump Truck
A side dump truck also known as an SDT consists of a 3-axle tractor pulling a 2-axle semi-trailer. It has hydraulic rams that tilt the dump body onto its side, spilling the material to either the left or right side of the trailer. The key advantages of using an SDT are that it allows rapid unloading and can carry more weight.
In addition, it is almost immune to upset or tipping over while dumping, unlike the semi end dumps which are very prone to tipping over. It is, however, highly likely that a side dump trailer will tip over if dumping is stopped prematurely.
Also, when dumping loose materials or cobble sized stone, the side dump can become stuck if the pile becomes wide enough to cover too much of the trailer’s wheels.
Trailers that dump at the appropriate angle, 50° for example, avoid the problem of the dumped load fouling the path of the trailer wheels by dumping their loads further to the side of the truck, in some cases leaving sufficient clearance to walk between the dumped load and the trailer.
Winter Service Vehicles
Many winter service vehicles are based on dump trucks, to allow the placement 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 needs heavy-duty trucks.
A Roll-off has a hoist and subframe, but nobody, 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 placed to be loaded or stored.
The hoist is raised and the container slides down the subframe so the rear is on the ground. The container has rollers on the rear and can be moved forward or back until the front of it is lowered onto the ground.
The containers are usually open-topped boxes used for rubble and building debris, but rubbish compactor containers are also carried. A newer hook-lift system does the same job, but lifts/lower and dumps the container with a boom arrangement instead of a cable and hoist.
Off-Highway Dump Trucks
Off-highway trucks are heavy construction equipment and share little resemblance to highway dump trucks. These bigger, off-highway vehicles are used strictly off-road for mining and heavy dirt hauling jobs.
There are two primary forms: a rigid frame and an articulating frame. The term “dump” truck is not generally used by the mining industry, or by the manufacturers that build these machines. The more appropriate U.S. term for this strictly off-road vehicle is “haul truck”.
Haul trucks are used in large surface mines and quarries. They have a rigid frame and conventional steering with the drive at the rear wheel. As of late 2013, the largest ever production haul truck is the 450 metric ton BelAZ 75710, followed by the Liebherr T 282B, the Bucyrus MT6300AC, and the Caterpillar 797F, which each have payload capacities of up to 400 short tons.
Most large size haul trucks employ Diesel-electric powertrains, using the Diesel engine to drive an AC alternator or DC generator that sends electric power to electric motors at each rear wheel. The Caterpillar 797 is unique for its size, as it employs a Diesel engine to power a mechanical powertrain, typical of most road-going vehicles and intermediary size haul trucks.
Other major manufacturers of haul trucks include SANY, XCMG, Hitachi, Komatsu, DAC, Terex, and BelAZ.
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 power unit is a permanent fixture, not a separable vehicle.
Steering is accomplished via hydraulic cylinders that pivot the entire tractor in relation to the trailer, rather than a rack and pinion steering on the front axle as in a conventional dump truck.
By this way of steering, the trailer’s wheels follow the same path as the front wheels. Together with all-wheel drive and low center of gravity, it is highly adaptable to rough terrain. Major manufacturers include Volvo CE, Terex, John Deere, and Caterpillar.

What You’re Hauling
Dump truck 101 – what are you hauling and how much does it weigh. This is a very important question and answer. You want to look at the gross vehicle weight rating (GVWR) of the make and model of dump truck you’re looking to buy.
To reduce damage to federal highway roads and bridges, federal law limits the gross weight of trucks based on the number and spacing of axles.
Determining what you’re going to haul on a regular basis will help determine which type of dump truck you’re going to need. (A detailed list of the different type of dump trucks above)
Determine Your Engine
Many of the dump truck manufacturers come equipped with similar engines. Whether it’s a Cummin’s, Detriot Diesel, Paccar Engines. Mack has its own line of engines names the Mack MP Engines.
You’ll need to determine what you’re going to haul and what the GVWR is going to be. You’ll need enough horsepower and torque to efficiently haul your loads. Not having enough horsepower can cause issues, and buy an engine that’s too power may be more costly. You want to find a happy medium of power and fuel efficiency.
Type of Transmission
Depending on your make and model you’ll be able to choose between manual or automatic.
There are several pros and cons between manual vs automatic. A lot of it has to do with personal preference, the make, and model of your dump truck, and what your skills level is when it come to driving a manual transmission.
The old school driver loves the control of a manual transmission. But, the newer automatic transmission are easy to drive and very efficient.
The automated manual transmission is gaining popularity. It eliminates the clutch and the hand shifting of a manual transmission. Instead, electronic sensors, processors, and actuators do the shifting to match travel speed with the load and job application.
Depending on the make and model of your dump truck, the manufacturers typically have two choices of axle positions. Axle forward and axle back.
The positioning of the axles can greatly affect your turning radius and maneuverability. If you need to be able to make tighter turns you probably want to look at an axle-back dump truck configuration.
How To Finance A Dump Truck
A dump truck lease is different from traditional vehicle financing and leasing. Traditional truck loans typically require your credit, business revenue, and time in business to determine if you’re qualified.
When it comes to leasing a dump truck, the truck you decide to purchase becomes the collateral, which helps to limit the lender’s risk on the lease. By reducing the risk you’re more likely to be qualified for truck financing.
Several factors will determine your box truck lease term, interest rate, and down payment. Here’s a list of all the requirements and factors that determine your eligibility and financial requirements.
