  • Patent number: 5513944
    Abstract: The disclosure is directed to convert any fork lift truck to a roll turning fork truck by sliding a specially designed rectangular frame onto the truck forks. Two safety chains are incorporated to firmly attach the device to the fork lift carriage. The frame combines a power winch and cable that engages a roll or coil core via a roll center lift in combination with an arm proceeding out from the roll center lift to the outside mid-width of the roll or coil which is attached to an adjustable fixed length chain. By lowering or raising the winch cable past the fixed length chain, rolls can be turned to either a true horizontal or vertical position. The adjustable "L" frame suspends from the fixed length chain at the lowest point with a pivot pin to achieve the turning feature when the winch cable is activated. Even though a fork truck may be stationary, the center lift is free to guide into the roll because the roll center lift is connected to a flexible cable and flexible chain.
