US Patent:

56181558, Apr 8, 1997

Filed:

Aug 8, 1994

Appl. No.:

8/287131

Inventors:

Peter Tighe - Bow NH

International Classification:

E02F 300

US Classification:

414680

Abstract:

A hauling system for loose bulk material at a construction site uses a self-propelled vehicle and a trailer that is not self-propelled which are releasably connected by a system that is operable by a single operator who aligns, connects, locks, unlocks and disconnects the self-propelled vehicle and the trailer, preferably without leaving the cab of the self-propelled vehicle. A hook secured on a tool of the self-propelled vehicle and a ring secured, directly or indirectly, to the trailer, releasably connect them. Rotation of the tool, e. g. the bucket of a wheel loader, locks and unlocks the coupling. The operator of the self-propelled vehicle has direct visible sight of the coupling. The ring can be mounted at the end of an articulated frame pivotally connected to a hydraulic jack cylinder. A dump body of the trailer can be raised by a hoist piston.

Abstract:

A hauling system for a self-propelled vehicle and a trailer that is not self-propelled in which the self-propelled vehicle and the trailer are releasably connected by a system that is operable by a single operator who can align and connect the self-propelled vehicle and the trailer from the cab of the self-propelled vehicle. Lateral alignment is achieved by steering the self-propelled vehicle and is facilitated by masts located on the self-propelled vehicle and the trailer that are visible from the cab. Vertical alignment and the physical connection are completed through use of a jack or other lifting mechanism that is positioned on the trailer and is operated by a wireless control signal sent from the cab.
