ABSTRACT:
A load carrying attachment has a supporting frame mounted on an elevationally movable carriage assembly mounted uprights of a lift mast and a load engaging frame having a load engaging device. A connecting device connects the load engaging frame to the supporting frame and guides the load engaging frame for movement in a preselected plane in directions transverse the uprights. The load engaging frame is freely transversely movable in the plane in response to an external force being applied to the load engaging frame and alleviates damage to the load engaging frame or a carried load due to misalignment with a transporter. A sensing device is provided for sensing the position of the load engaging frame and delivering a vehicle braking signal in response to the load engaging frame being at either a first or a second preselected transverse position. The load carrying attachment is particularly suited for use on an automatic guided vehicle.
