Abstract
Abstract An apparatus for handling, loading, unloading and transporting containers, load supporting bodies, pallets and like bulky and heavy objects with the use of a transport vehicle and a fork lift type lifting device disposed on the transport vehicle. The fork lift device is pivoted to one end of the transport vehicle in such a way that the frame carrying the fork lift device can be pivoted between a vertical position and a position coplanar with the chassis of the transport vehicle. Coupling means associated with the fork lift device is designed so as to permit being coupled with mating coupling means associated with the end of a load supporting body which is usable as a transportation support for containers and like objects. When the load supporting body is coupled with the fork lift device, the body can be pulled onto and lowered from the transport vehicle under simultaneous pivotment of the frame of the fork lift device and shifting of the fork lift device along the frame thereof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
194 words
An apparatus for handling, loading, unloading and transferring heavy articles comprising a transport vehicle, an elongated frame pivotally mounted on the rear end of said vehicle for movement about a first horizontal axis extending transversely of said vehicle, means moving said frame about a first horizontal axis between a substantially horizontal position and a generally vertical position, a fork lift device, mounting means supporting said fork lift device on said frame for movement theralong, pivot means mounting said fork lift device to said mounting means for pivotal movement about a second horizontal axis extending generally parallel to said first hoizontal axis, means pivotally moving said fork lift device about said second axis, whereby said frame and said fork lift may be pivoted about their respective axes simultaneously, a load supporting body, and cooperating coupling means on said fork lift device and said supporting body whereby, upon engagement of said cooperating coupling means, said body may be loaded onto said vehicle by simultaneous movement of said frame about said first axis and of said fork lift device along said frame and about said second axis, said apparatus also being operable as a conventional fork lift.
Claim 2
Independent Claim
194 words
An apparatus for handling, loading, unloading and transferring heavy articles comprising a transport vehicle, an elongated frame pivotally mounted on the rear end of said vehicle for movement about a first horizontal axis extending transversely of said vehicle, means moving said frame about a first horizontal axis between a substantially horizontal position and a generally vertical position, a fork lift device, mounting means supporting said fork lift device on said frame for movement theralong, pivot means mounting said fork lift device to said mounting means for pivotal movement about a second horizontal axis extending generally parallel to said first hoizontal axis, means pivotally moving said fork lift device about said second axis, whereby said frame and said fork lift may be pivoted about their respective axes simultaneously, a load supporting body, and cooperating coupling means on said fork lift device and said supporting body whereby, upon engagement of said cooperating coupling means, said body may be loaded onto said vehicle by simultaneous movement of said frame about said first axis and of said fork lift device along said frame and about said second axis, said apparatus also being operable as a conventional fork lift.
Claim 3
Dependent Claim
31 words
An appartus as claimed in claim 1 wherein the frame with the fork lift device is pivotally mounted at the rear end of a substantially rigid chassis of said transport vehicle.
Claim 4
Dependent Claim
37 words
An apparatus as claimed in claim 1 wherein the frame is a pivotally mounted part of the subframe of a one-axle semitrailer, and the wheels of the semitrailer are mounted to said part formed by the frame.
Claim 5
Dependent Claim
26 words
The apparatus as defined in claim 1 wherein said load supporting body comprises a wheeled platform having a load bearing surface adapted to support heavy articles.
Claim 6
Dependent Claim
38 words
The apparatus according to claim 1 wherein said cooperating coupling means includes means permitting limited pivotal movement between said load supporting body and said fork lift device as said load supporting body is being loaded onto said vehicle.
