The tailga-te 50 is arranged to swing completely open so that it will rest beside the side member 1~ and a locking pin 55 at-tached to the back of the U-shaped frame holds the tailgate 50 in the open position. When the tailgate 50 is in the open position, the unit may be used as a forklift because the forks 30 are cantilevered out from the upright frame 30 of the U-shaped frame. Curved ends 56 are provided on the inside of the two side members 12, these are designed to assist in positioning the unit 10 about a pallet, package or other load, which is to be lifted by the lifting forks 30.
Two apertures 58 are provided in the tailgate 50 and in order to close the tailgate 50, the lifting forks 30 are raised to the towing position, the~tailgate 50 is then closed and the tapered ends 3~ of the lifting forks 30 protrude through the apertures 58 and rest on the tailgate 50. Thus in the towing position, the lifting forks 30 are firmly locked in place and cannot be raised or lowered because of the apertures 58 in the tailgate 50 and the locks 40 at the cross member 34 o the unit.
A swivel wheel 60 is shown positioned at the center of the back member 11. The swivel wheel 60 ls raised when the unit ls ln the towing posik~on, but when it ls in the manoeuvring posltion with the tailgate 50 open, the swivel wheel is lowered allowing the unit to be supported on the two wheels 18 and the swivel wheel 60.
