Hoisting device for use in overhead crane, has two linearly movable frames directly connected to connection element, and two pressure control arms provided in vertical plane parallel to long side of lifting load
The device has two linearly movable frames (2) directly connected to a connection element, and two pressure control arms (3) provided in a vertical plane parallel to a long side of a lifting load (21), where the pressure control arms are driven by a motor (5). The connection between the frames is formed by a bar, where the connection between the frames is governed by a shear mechanism.
