  • Patent number: 6675937
    Abstract: A fork-lift truck for selectively displacing a load forward or sideways, comprising a horizontal, substantially U-shaped frame, a lifting mechanism for carrying the load, wherein legs of the frame extend along the lifting mechanism, and wheels on the legs which are connected to the legs via rotating mechanisms for driving and are rotatable on a substantially upward axis between positions corresponding with sideways and forward movements of the fork-lift truck. Flexible power supply and control lines run with slack through the legs to the wheels. There is further provided a bending mechanism at each of the legs for bending the power supply and control lines without frictional contact with the interior of the legs during release of the slack.
