  • Patent number: 5879124
    Abstract: A collapsible forklift vehicle has three frame sets, namely a main frame, a pair of front wheel frames which can be retracted into the main frame, and a mast frame which runs partly on the main frame and partly on the front wheel frames. The main frame defines a rear space for the rear wheels, and motor and operator platforms, all of which can be retracted into the rear space to shorten the vehicle for transport. The mast, carried by the mast frame, includes intermediate channels running in outer channels using top and bottom rollers, enabling the use of lighter gauge steel for the mast.
