A Super Tag is similar to a standard dump truck but is equipped with a tag axle behind the rear-drive axles. The body is longer and is slanted toward the back, which allows for the load to be placed in the truck bed to maximize the payload.
5 axle, 20-24 yd.
A transfer dump (colloquially referred to as a “Slam-Bang!” because of the noise made when transferring) is a standard dump truck which pulls a separate trailer that can be loaded with aggregate.
The aggregate container (B box) on the trailer which is powered by either an electric or hydraulic motor rides on wheels and rolls off the trailer and into the main dump box. The key advantage of this configuration is to maximize payload capacity without sacrificing the maneuverability of the short and nimble standard dump truck. Transfer dumps are typically seen in the western United States because of the peculiar weight restrictions on western highways.
4 axle, 20 yd.
A super dump is similar to a standard dump truck except it is equipped with trailing axles or sting axle to maximize the payload
5 axle, 20 yd.
A semi-end dump is a tractor-trailer combination wherein the trailer itself contains the hydraulic hoist. A typical semi-end dump has a 3-axle tractor pulling a 2-axle semi-trailer. The key advantage of a semi-end dump is rapid unloading.
5 axle, 20 yd.
A semi-bottom dump (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-bottom dump is its ability to lay material in a wind row. In addition, a semi-bottom dump is maneuverable in reverse, unlike double and triple trailer configurations.
5 axle, 20-24 yd.
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 wind rows without ever leaving the cab or even stopping the truck. The main disadvantage is the difficulty in backing double and triple units in reverse.
