ABSTRACT:
A load-weighing device for indicating the weight of a load is provided for attachment to the load-carrying member of a lifting device. The load-weighing device includes a frame connected to the load-carrying member and a bearing block mounted in the frame for rotation relative to the load-carrying member. A clearance space is provided between the lower surface of the bearing block and the frame which is eliminated upon the application of a load. A bearing member is also mounted in the frame and includes a cylindrically-shaped lower surface which is arranged to abut a cylindrically-shaped upper surface of the bearing block. The bearing member is provided with a recess for receiving a pressure-sensitive member so that when a load is lifted by the load-carrying member, the force of the load is transferred to the pressure-sensitive member which operates to provide a load-measuring value to a receiver.
