Abstract: A canopy of a dump body for a truck comprises a deck having a length and a width greater in dimension that the length defined by a front edge, a rear edge opposite the front edge, a first side edge, and a second side edge opposite the first side edge. The deck can define an upper surface and a lower surface opposite the upper surface. In a front view the deck can define a concave shape, with a center portion and stepped portions between the center portion and the first and second side edges.

Abstract: A hoist structure for a body of a truck can be comprised of a hoist plate arrangement extending in a first direction and configured to be rotatably coupled to a hoist member of the truck; and a plurality of external gussets spaced from each other in the first direction and extending in a second direction perpendicular to the first direction. Each of the external gussets can interface with the hoist plate arrangement, and a portion of each of the external gussets can extend in the second direction from a first side of the hoist structure arrangement.

Abstract: A dump body comprising a front wall, a canopy extending from the front wall in a first direction, and a bottom wall extending from the front wall in a second direction different from the first direction. The front wall, the canopy, and the bottom wall can form an interface configured to receive at least one pair of side walls. The bottom wall can have a convex shape in a transverse direction of the dump body and/or a longitudinal direction of the dump body. The bottom wall can be inclined according to one or more distinct angles from a front edge of the bottom wall to a rear edge of the bottom wall.

Abstract: A front tower on a truck body for use with a mining vehicle. The truck body includes a truck bed including a canopy and a front exterior wall. The front exterior wall includes at least one front tower. The front tower includes two longitudinal plates spanning the front exterior wall, at least one gusset plate transverse and connected to the longitudinal plates, and a landing plate transverse and connected to the longitudinal plates. The landing plates are configured to transfer load stress from the bed to a frame of a mining vehicle.
