When determining what kind of trailer is best for your application – side-dump, belly-dump, or end-dump – it’s important to have an understanding of the engineering behind each. If you’ve been constrained in your operations due to the limitations of your trailer, you might just find that a side-dump opens new doors for you.
End-Dump Trailers – Classic Design with Stability Challenges
An end-dump is what most people picture when they hear the term “dump truck.” As its name implies, an end-dump trailer unloads out of its rear, with the “box” lifted into the air. With an end-dump, the box has to be raised high enough to unload its cargo, making the unit unstable, especially on uneven ground. End-dumps can also become more unstable due to loads shifting, and typically aren’t suitable to haul liquids, since it is challenging to make the rear gate watertight.
Belly-Dump/Bottom-Dump Trailers – Stable, but Limited Applications
The belly-dump concept has been around since the days of horse-drawn trailers. Today’s models use a “clam shell” type dump gate to dump material straight from the bottom of the box. This enables windrowing – unloading the material in a long line rather than a single pile. Belly-dumps also have limitations in the type of materials they haul. Because the axles of the trailer must have clearance above the windrow, bottom-dumps are not suitable for larger pieces that will hang up under the suspension. Belly-dumps can’t haul fine material or liquid that will leak out of the bottom gates.
Side-Dump Trailers – Greater Stability and Versatility
The side-dump trailer concept was born in the early 1990s as a way to eliminate the costly and dangerous tipover issues associated with end-dump trailers, as well as solving the challenges of belly-dumps. Side-dumps, of course, unload their cargo by tilting the trailer to one side, which provides greater stability. Side-dump trailers do not require the air in the suspension to be dumped prior to dumping the load. Side-dumps are easy to operate from within the cab and can dump on soft and uneven ground safely; there is no need to back up or find a level area to unload.
With a side-dump trailer, operators can safely haul and unload a wide variety of materials. From boulders to wet material, the load releases faster and more safely. Plus, side-dump trailers allow you to stockpile AND windrow, and do it with a faster dump cycle, enabling more efficiency in your operations.
