Dump body for mounting on the frame of a vehicle

摘要

A dump body for mounting on the frame of a vehicle is disclosed. The dump body comprises a floor, side walls and a front wall secured together to form an integral unit, a rear gate closing the back of the unit. The floor is composed of a central, elongated plate and a pair of elongated lateral plates, each of smaller thickness than the central plate, so that the latter will resist abrasion for a longer time, where abrasion is most likely to occur and yet reducing the weight of the dump body. The lateral plates extend underneath and overlap the central plate and are bent to form integral, longitudianally-extending hollow beams welded to the central plate for strengthening the unit.
