ABSTRACT:
A truck-mounted articulated mechanism for loading and unloading cable reels onto and from a flatbed mobile truck, comprises a pair of lift arms, one on each side of the truck, pivotally movable, by hydraulic rams, about a transverse shaft mounted in the free ends of a pair of transfer arms which are pivotable about pivot pins fixed in the truck frame. This mechanism lifts and lowers the cable reel between ground and the rearward end of the bed of the vehicle. Locking mechanisms, actuable by hydraulic pistons, lock the axle of the cable reel in a recess in each of the lift arms during the lifting and lowering operations. The pivotal transfer arms, one on each side of the truck, actuable by hydraulic rams, transfer the cable reel, while its axle is still locked in the recesses of the lift arms, between the rearward end and the forward end of the flatbed truck. A locking mechanism, actuable by hydraulic pistons, lock the axle of the cable reel in its storage position at the forward end of the truck. A second reel may be lifted and lowered by the lift arms between ground and a storage position at the rearward end of the truck. The transverse shaft means include a pair of concentric tubular torsion shafts, one inside the other, and having a common axis, for assuring that the pivotal movements of the lift arm and transfer arm on each side of the truck are in synchronism and alignment.
