A switch 17 is mounted at each end of the gantry to stop and reverse mechanism 16 for travel in the opposite direction. Teeth 19 are disposed on the gantry in the line of motion of mechanism 16, a pivotable and reversible double pawl of said mechanism engaging said teeth. Slidable bars 8, 9, 10 which can be mounted on the rear or on outriggers of a tractor, are attached respectively to a horizontal bar 2 at the top of the frame, and to struts 5 and 6.
