A load handling apparatus for a vehicle has a mounting frame with a mast movable between a lowered travelling position and a raised working position. A boom carrier on the mast pivotally supports an articulated boom, which has a winch at its distal end. The winch cable is attached to a load carrying cradle which has handle bars to be gripped by the operator and the switch controls for the winch. The mast is counterbalanced by a spring and turnbuckles connect the boom carrier to the mounting frame and the mast to tilt the boom carrier in two directions if the vehicle is on uneven ground.
