hoisting weight limiter will be triggered, with the switching value output displayed. The whole system is composed of sensor, connecting cable, WTZ-A20 Overload Limiter is a smart weigh overload protector, which measures the changes of the weight of the loaded goods by a preset weight sensor and displays the actual load instantly on the display instrument. When the load reaches the given point of rated load, the acousto-optic alarm of the microcomputer host and so on. The device is designed and manufactured in accordance with requirements of GB 12602-2009 “Lifting Machinery Overload Protection Devices” and GB / T 3811-2008 “Crane Design Specification”.
