Mechanism to empty trunnion equipped refuse container into side loading collection body

摘要

An automated side loading mechanism for a refuse collection body capable of lifting and emptying a refuse container equipped with a trunnion bar. A carriage reaches out from the side of the collection body and includes a lift mechanism. The lift mechanism includes pockets to receive opposing ends of the trunnion bar on the refuse container. Lock arms pivot downward so that bar members on the lock arms overlie top edges of the refuse container. The carriage is retracted and the lift mechanism is raised on the carriage so that the refuse container can be upended over the load opening of the collection body. The bars on the lock arms angle upwardly to allow plastic lids hinged to the refuse container to swing past the bars when the container is upended, while restraining the container from falling into the collection body.

主权项

1. A side loading mechanism for a commodity collection body having a compaction chamber forward of a storage compartment and a lifting mechanism adjacent a lateral side of the compaction chamber, the side loading mechanism comprising:
a pair of spaced apart trunnion pocket members, the trunnion pocket members movable in a substantially vertical direction, each trunnion pocket member including a trunnion pocket thereon, a pair of arms selectively rotatable about an axis, each arm rotatable between a first position and a second position, each arm including a bar member extending substantially noncoaxially therefrom, each bar member extending generally toward the other bar member when both arms are in the second position, each bar member inclining from horizontal when the arm is in the second position and the lifting mechanism is in a lowered position, the lifting mechanism joined to the trunnion pocket members, the lifting mechanism operable to elevate the trunnion pocket members from a lowered position to an elevated position at or above a loading opening of the collection body, a stabilizer extending below the trunnion pocket members when the lift mechanism is in the lowered position, the trunnion pockets selectively receive respective trunnions extending from opposing ends of a rear loading commodity container, each bar member overlying a top of an opposing end wall of the rear loading commodity container when the arms are moved to the second position, each bar member spaced a small distance from the top of the respective end wall when the arms are in the second position and the lifting mechanism is in the lowered position, the stabilizer urging a front wall of the rear loading commodity container to rotate about an axis defined by the trunnions when the trunnion pocket members are elevated to the position at or above the loading opening of the collection body, the bar members abutting the tops of the opposing end walls of the rear loading commodity container when the rear loading refuse container is substantially upended, preventing the trunnions of the real loading commodity container from falling from the trunnion pockets.
