Abstract

PURPOSE: A loading position of a workpiece is located easily by a hook device of a crane, thereby improving workability and reducing safety accident. CONSTITUTION: A hook device for a crane is composed of a frame(20) moved by the crane engaged with a wire. A hook(30) is supported by the frame to hook workpiece. A hook rotation controller(40) is controlled by a worker wirelessly rotating the hook in a certain angle. The hook rotation controller comprises a driving portion having a clutch function to connect or disconnect driving power to rotate the hook.
