Tipping and self-unloading bodies for aggregate, demolition, asphalt, refuse and other flowable bulk materials.
Choose material-hauling equipment around the commodity and the unloading site. The material’s flow, contamination sensitivity and tendency to bridge matter as much as body volume. Tipping, bottom discharge, conveyor belts and reciprocating floors are different unloading mechanisms.
| Decision | What changes | Ask for |
|---|---|---|
| End or side dump | A body tips to discharge. Ground conditions, working clearance and the permitted unloading direction influence selection. | Site slope/bearing, overhead clearance, tailgate and tipping procedure |
| Bottom dump | Gates release material beneath the trailer. Placement and ground clearance differ from an agricultural gravity hopper. | Discharge pattern, gate controls, clearance and commodity behaviour |
| Belt or moving floor | A belt conveys material while reciprocating slats move the load through a different floor action. | Drive system, floor/belt wear, discharge clearance and cleaning method |
Confirm an unloading plan with the receiver. A larger body does not establish a larger legal payload, and a self-unloading mechanism does not remove the need for firm ground and controlled access. Check winter freezing and carryback risks for the commodity.
For route-specific checks, start with the applicable provincial authority. Alberta permit resources ↗ and Ontario permit resources ↗ explain their respective processes; neither is a Canada-wide clearance rule.

3 specification references cover 2 trailer architectures. Open the specification library for model-specific documentation.
Model references are supported by manufacturer documentation. Check each configuration for its available dimensions and ratings.
Each reference shows the feature that controls classification. It is not a dimension, rating, compatibility or availability source.
Body motion, gate location or powered floor path distinguishes the unloading architectures; similar commodities do not merge them.
Body tips rearward through a rear discharge.
Body rolls laterally to discharge beside the trailer.
Gravity discharge passes through gates below the body.
A continuous powered belt carries material to the discharge.
Reciprocating floor slats advance material without tipping the body.
