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.
TYPES
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. As u know that 16 dump trucks starting at $35,000
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.
