Abstract

A roll on roll off receptacle handling system, that can load and unload a receptacle, store the receptacle and transporting the receptacle. The system includes a storage platform or independent support, such as portable jacks, for supporting the receptacle when it is rolled off the transport device. The transport device, that the receptacle can be rolled on to, can transport the receptacle to another location where it can be rolled off to another platform or independent support. The system also includes power assist devices for operating the jacks and for moving the receptacles to and from the transport device.

Claims

1. A transport vehicle adapted to move in a longitudinal direction, independent supports borne by the ground, and a plurality of modular containers supported on said transport vehicle at predetermined elevations above the ground and movable from said transport vehicle, in a lateral direction, to said independent supports at said predetermined elevations above the ground;

said transport vehicle adapted to receive said modular containers from and unload said modular containers to said independent supports as a result of the modular containers being moved relative to the transport vehicle in a direction normal to the longitudinal direction of said transport vehicle; and

each of said independent supports includes a plurality of jacks that are releasably attachable to said modular containers.

2. The invention as set forth in claim 1 in which said transport vehicle and containers have cooperating anti-friction mechanisms, that will support said containers on said transport vehicle to thereby provide a stable support for said containers during transport and to facilitate relative movement between a said container and said transport vehicle to a first position at which said transport vehicle is the sole support of said container and a number of said independent supports can be engaged to accept responsibility for a portion of the support for the container and then to a second position at which said transport vehicle supports a portion of the load of said container and a further number of said independent supports can be further engaged to accept responsibility for the remaining portion of the support for the container from the transport vehicle.

3. The invention as set forth in claim 1 in which each of said independent supports are independently movable from inoperative positions to operative positions at which they accept responsibility for a portion of the support of said modular containers.

4. The invention as set forth in claim 1 in which said jacks have ground engaging wheels.

5. The invention as set forth in claim 1 wherein each of said jacks include ground engaging jacking mechanisms that can adjust the height of said modular containers relative to the ground and raise said modular containers off said transport vehicle, such that said modular containers are ground supported, to thus permit movement of the transport vehicle away from said modular containers.
