When choosing a trailer, there are two popular choices: end dumps and side dumps. This comparison chart highlights the differences between end dumps and side dumps so you can make the most appropriate selection for your operation.
Compare safety features, materials and placement, cylinder replacement costs, sidewall dimensions, cycle times and resale value.
End Dump Trailers: Standard Trailer Design with Several Disadvantages
End dumps have been on the market for a long time. When backing up or unloading, the operator’s view is obstructed by the tub. During the dump cycle, the front end of the tub must be lifted high enough to empty everything inside, fully exposing the cylinder. The unit can become unstable due to loads shifting or gaining momentum while dumping. End dumps are not watertight, limiting the type of materials that can be hauled.
Side Dump Trailers: More Stable and Versatile
Side dumps were first developed in the 1990s as a solution to tipover issues with end dumps. Side dumps unload by tilting to the side, hence their name. Rugged side dumps can haul almost any material from fine sand to boulders and debris to waste sludge, silage, and other agricultural products. They offer the added convenience of being able to dump from within the truck cab with clear sight lines. The side dump trailer’s design is watertight. When used with a tarp, this allows for an even wider variety of materials

Differences between side dumps, end dumps and belly dumps
When determining what the best dump trailer is 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.
