Abstract

A lifting system for lifting a person into a construction vehicle for operation thereof, including a wheelchair compatible seat which detaches from a wheelchair; and a lifting mechanism including a rack and pinion mechanism, mounted to a top portion of the construction vehicle, a rack portion of the rack and pinion mechanism being movable outwardly and inwardly with respect to a side of the construction vehicle, a crane assembly disposed on the rack portion and having a lifting cable with a clip mounted on the end, and a lifting harness connected to the wheelchair compatible seat and connected to the clip, wherein when the clip is connected to the harness, the crane assembly of the lifting mechanism is activated and the wheelchair compatible seat is lifted up from the wheelchair, moved inwardly by the rack portion to a seat position of the construction vehicle, and lowered into the seat position.

Claims

1. A lifting system in combination with a construction vehicle, for lifting a person into the construction vehicle for operation thereof, comprising:

a wheelchair compatible seat which is operative to detach from a wheelchair; and

a lifting mechanism comprising a rack and pinion mechanism that is mounted to a top portion of the construction vehicle, a rack portion of the rack and pinion mechanism being movable outwardly and inwardly with respect to a side of the construction vehicle, a crane assembly disposed on the rack portion of the rack and pinion mechanism and having a lifting cable with a clip mounted on an end of the lifting cable, and a lifting harness connected to the wheelchair compatible seat and operative to be connected to the clip,

wherein when the clip is connected to the harness of the wheelchair compatible seat, the crane assembly of the lifting mechanism is activated and the wheelchair compatible seat is lifted up from the wheelchair, moved inwardly by the rack portion to a seat position of the construction vehicle, and then lowered into the seat position.

2. The lifting system in combination with a construction vehicle of claim 1, wherein the rack and pinion mechanism is disposed in a housing mounted onto a top of a Roll-Over Protective Structure (ROPS) of the construction vehicle.

3. The lifting system in combination with a construction vehicle of claim 1, wherein the crane comprises a motor driven winding drum for wing up and letting out the lifting cable.
