Abstract: A hoist assembly for movable actuation of a dump body relative to a truck frame is disclosed. The dump body includes an underbody floor assembly with a first cross-member and a second cross-member. The first cross-member and the second cross-member are spaced apart from each other and are rectangular-shaped. The hoist assembly includes a cylinder assembly with a rod member movably positionable within a cylinder body. The cylinder body is coupled to the truck frame. A rod end mounting assembly includes a bracket member to distribute a weight of the dump body to the cylinder assembly. The bracket member includes a first end integrally and contiguously attached to two adjacent sides of the first cross-member, and a second end integrally and contiguously attached to two adjacent side of the second cross-member. Moreover, an end of the rod member is coupled to a center portion of the bracket member.
