ABSTRACT:
A roll-off trailer or truck bed for hauling cargo includes a cargo controlling mechanism that allows for the controllable removal of the cargo. The roll-off trailer characteristically includes a plurality of rotatable rollers disposed transverse to the longitudinal length of the trailer. The cargo controlling mechanism includes a brake mechanism preferably associated with at least several of the plurality of rollers. When actuated, the brake mechanism retards, stops, or nonrotatably restrains rotational movement of the rollers in order to slow down or stop the off-loading of the cargo. Actuation of the brake mechanisms may be accomplished through hydraulic, electric, pneumatic, mechanical, or other means. Each brake mechanism may be separately controlled by the operator in order to selectively retard the rotation of the desired roller. Alternatively, a number of brake mechanisms may be linked together to constitute a group. A control assembly regulates the brake mechanisms of the group. Furthermore, several groups may be separately controlled through the control assembly.
