All dump trucks operate by hydraulics and they come in a variety of configurations each designed to accomplish a specific task in the construction material supply chain.
Dump truck type:
Standard dump truck
The shorter wheelbase of a standard dump truck often makes it more maneuverable than the higher capacity semi-trailer dump trucks.
Dump truck configurations are 2, 3 and 4 axles. The 4-axle eight wheeler has two steering axles.The largest of the standard dump trucks are commonly called a "centipede" and has seven axles. The front axle is the steering axle, the rear two axles are powered, and the remaining four are lift axles.lift axles can be raised off the ground to minimize wear when the truck is empty or lightly loaded.
Semi trailer end dump truck
Semi trailer end dump truck is a tractor-trailer combination wherein the trailer itself contains the hydraulic hoist.The key advantage of a semi end dump are a large payload.
Transfer dump truck
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.
Transfer dump trucks typically haul between 26 and 27 short tons (23.6 and 24.5 t; 23.2 and 24.1 long tons) of aggregate per load, each truck is capable of 3-5 loads per day, generally speaking.
Super dump truck
Super dump truck is a straight dump truck equipped with a trailing axle, a liftable, load-bearing axle rated as high as 13,000 pounds (5,897 kg). Depending on the vehicle length and axle configuration, Super dumps truck can be rated as high as 80,000 pounds (36,287 kg). 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. Truck owners call their trailing axle-equipped trucks Superdumps truck because they far exceed the payload, productivity, and return on investment of a conventional dump truck.
Semi trailer bottom dump truck
Semi trailer bottom dump truck or belly dump is a 3-axle tractor pulling a 2-axle trailer with a clam shell type dump gate in the belly of the trailer. The key advantage of a semi trailer bottom dump truck are its ability to lay material in a windrow, a linear heap.
