ABSTRACT:
A device adapted to operably engage a vehicle to load and unload a container between the vehicle and a surface, and to cooperate with the vehicle to transport the container, is provided. Such a device includes a pair of laterally separated horizontal lifting members configured to be vertically movable with respect to the vehicle and a vertically-movable member operably engaged with the forward ends of the lifting members. A tether is operably engaged between each lifting member and the container so as to secure the container thereto. A translatory device is engaged between the vehicle and the vertically-movable member and configured to support the lifting members as well as move the lifting members longitudinally with respect to the vehicle. To unload the container, the vertically-movable member and the lifting members raise the container above the vehicle and then the translatory device longitudinally moves the container along the vehicle past a vertical plane defined by the rearward end thereof. The container is then lowered to the surface by the vertically-movable member and the lifting members and the tethers disengaged from the container. The reverse procedure loads the container onto the vehicle. Associated devices, systems, and methods are also provided.
