ABSTRACT:
Converts any fork lift truck to a roll turning fork truck by sliding a specially designed rectangular frame onto the truck forks. A safety chain is incorporated to firmly attach the device to the fork lift carriage. The frame combines a power hoist, with load sensing brake, and cable that engages a roll or coil core via a roll center lift, which continuously grips the core firmly, 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 hoist 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 hoist 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.
