Abstract
A dump bed assembly (18) is provided for coupling to a truck having a chassis (22) for supporting the dump bed assembly (18). The dump bed assembly (18) includes a cargo receiving dump bed (13) coupled to the chassis (22) and movable between a travel configuration and a dump configuration. The dump bed includes a metal skeletal frame (85) including a plurality of frame members that define a plurality of openings (171) between the frame members. A plastic bed (90) comprises at least one plastic bed member coupled to and supported by the plurality of frame members. The plastic bed member extends into the openings defined by the frame members.

20. A dump bed assembly for coupling to one of a truck or trailer having a chassis for supporting the dump bed assembly, the dump bed assembly comprising
a cargo receiving dump bed coupled to the chassis and movable between a travel configuration and a dump configuration, the dump bed including a longitudinal axis extending generally along a primary intended direction of travel of the dump bed assembly, the cargo receiving dump bed including a metal skeletal frame comprising a plurality of frame members that define a plurality of openings between the frame members; - and a plastic bed comprising at least one plastic bed member coupled to and supported by the plurality of frame members and extending into the openings defined by the frame members,
wherein the plurality of frame members include; first and second longitudinal top rail members extending generally parallel to the longitudinal axis of the dump trailer assembly, first and second longitudinal lower rail members extending generally parallel to the longitudinal axis of the dump trailer assembly, and disposed at a level lower than the longitudinal top rail members, and first and second lateral rail members extending generally perpendicular to the longitudinal axis of the dump trailer assembly, the first and second lateral rail members being coupled to the first and second longitudinal top rail members and the first and second longitudinal lower rail members wherein the dump bed assembly has a generally hemi-cylindrical shape; and
the plastic bed includes a first side edge and a second side edge, andfurther comprising a first slotted receiver extending generally parallel to the first longitudinal top rail for receiving the first side edge of the plastic bed, and a second slotted receiver extending generally parallel to the second longitudinal top rail for receiving the second side edge of the plastic bed, the first slotted receiver being formed as a part of the first longitudinal top rail member; and
the second slotted receiver being formed as a part of the second longitudinal top rail member,wherein the metal skeletal frame is disposed primarily exteriorly of the plastic bed, the plastic bed includes at least one unitary plastic bed member that extends between the first slotted receiver and the second slotted receiver, and wherein the unitary plastic bed member and the first and second slotted receivers are sized and positioned to cause the plastic bed member to remain received by the first and second slotted receivers over a normal range of thermal expansion of the plastic bed member.
- and a plastic bed comprising at least one plastic bed member coupled to and supported by the plurality of frame members and extending into the openings defined by the frame members,
