Device for handling and weighing loads has a mechanism whereby an operating force is used to control raising and lowering of the load using a lifting device rather that used to raise or lower the load directly

摘要

Device for handling weights has a cylinder and piston arrangement (1, 2) for producing a force opposing the weight and a measurement cell (4). A control device (24) is used to match the counter force based on a signal from the measurement cell. A handle (22) is used to apply a force additional to the weight that is then detected by the measurement cell and used to adjust the counter force. The handling or operating force is not used to directly lift or lower a load, but instead operates on a measurement cell so that the load is lifted or lowered by a lifting device.
