A roll off trailer includes first and second trolley assemblies and a hoisting cable connected at one end to the first trolley assemble and extending about a sheave in each of the first and second trolley assemblies. The cable connects to a container. The second trolley is displaced in a first direction while simultaneously drawing the container via the cable from the first grounded container position to a second container position generally midway atop the trailer. Then, the first trolley is displaced in a second direction while simultaneously drawing the container via the cable from the second container position to a third container position generally adjacent the front of the trailer.

A skip apparatus for a working vehicle has a skip that is pivotable upward about a carrying axle and that has a pouring edge via which pourable material is able to be poured out of the skip. The skip apparatus additionally has an emptying device which is pivotable relative to the skip about a pivot axle on the skip during a pivoting movement. The emptying device has an inlet side and an outlet side. The inlet side is arranged in a region of the pouring edge such that the pourable material, which is poured out of the skip via the pouring edge, passes into the emptying device via the inlet side. The pivoting movement of the emptying device is guided in a defined manner by a guiding device. A working vehicle having such a skip apparatus also is provided.

The present invention relates to a motorized device that can be operated by one person to load or unload a platform containing cargo or a wheel chock attached to a motorcycle or multi-wheeled vehicle, or bins and containers holding cargo. The device taught herein is employed to lift or move the cargo to the level of the truck bed or storage area and move into the storage or travel to a second position. Also disclosed is a sliding ramp apparatus for moving cargo to a higher level or lower level or movement on the same plane or level using incline, horizontal or vertical movement. When mounted on a platform or motorized vehicle, any cargo: machinery, motorcycle, containers, palettes, drums, supplies, etc. can be loaded or unloaded in or on a vehicle or platform in a lifting or lowering manner. When mounted on any surface, any cargo (worktables, machinery, crates, containers, pallets, drums, supplies, boats, etc.) can be moved horizontally and/or vertically for access or convenient height, human contact or manipulation of cargo or process in manufacture.

A vehicle mounted loading and unloading apparatus is provided which has a stationary mounting rack removably attachable to a roof of a vehicle and a top rack that includes a container for storing cargo, such as bales of hay. An adjustment mechanism is provided to move the top rack relative to the mounting rack from a transporting position to a loading/unloading position in which the top rack is lowered behind the vehicle to facilitate loading cargo. A movable shelf may be provided on the top rack for assisting with loading and unloading cargo. The shelf is slidable between a rear end of the top rack and a front end of the top rack for placing the cargo.

An inertia-driven dump load apparatus is provided in association with motor vehicles. The inertia-driven dump load includes a container defined by two side walls and a front wall; and at least one pivotable connection means connecting the container to the vehicle bed. To operate the inertia-driven dump load apparatus, the apparatus is first placed within a vehicle bed. Once the apparatus is in place, material to be dumped can be loaded into the apparatus. Then, the vehicle is driven to a location where the dumping of the materials is desired. Finally, a force is applied to the apparatus such that the apparatus moves across the vehicle bed so that the apparatus tips over a tailgate of the vehicle bed so that the material to be dumped is dumped.

An apparatus for loading and unloading containers of various sizes onto and off of a roll-off vehicle comprises a top frame and at least one lift actuator operable to pivot the top frame away from a horizontal home position to rearwardly incline the top frame. The top frame includes a main portion, a head portion longitudinally displaceable relative to the main portion, a plurality of sheaves, a cable extending through the sheaves, and a hoist actuator operable to displace the head portion between a retracted position and an extended position. The cable has a fixed end coupled to the head portion and a free end for coupling to a container. The hoist actuator is operated while the top frame is away from the home position to displace the head portion toward the extended position to load a container onto the vehicle, and toward the retracted position to unload the container.
