The forks are arranged with a central pair (28,29)and two side pairs (18,25) and (13,23). The spacing of the central pair is adjustable by cylinders (35,36) and the outer pairs by cylinders (33,34) with springs (37,38). These may be hydraulically set to lift three pallets or by closing up the outer pairs to the inner, two pallets or by closing up further one pallet.
