Tough. Trusted. Versatile.
More side dump models than anyone in the industry. One to seven axles, AR450 steel tubs, and a dump cycle that keeps the load low and the driver in the cab.
Why SmithCo
What makes
ours better
Every SmithCo trailer is engineered around one idea: keep the load low, keep the driver in the cab, and keep the trailer on the road instead of in the shop.

Eighteen ways
to move it
SmithCo produces more side dump trailers, and offers more side dump models, than any other company in the industry. Pick a family or search the whole catalog.
Capacity
Cubic yards,
side by side
Waterfull is level to the top rail, use it for wet loads. Heaped is mounded at the material's natural angle of repose.
Side dump vs. end dump
Where the hidden
costs are
An end dump raises the whole loaded body in the air. That's where tip-overs happen. Beyond the dump cycle, here's what separates a SmithCo from what else is on the lot.
Industries
Ready to go
to work
From construction to mining, high volume tubs to doubles and trains, and if your application calls for something unique, SmithCo designs a trailer specifically for your operation.
Cycle math
What faster
cycles are worth
Side dumps unload without backing up, without a tailgate, and without the driver leaving the cab. Put your own numbers in and see what that does across a season.
