Wireless anti-overwinding switch / Wireless anti-overwinding switch SM40-WK01
Product Categories Wireless anti-overwind switch
The wireless anti-overwinding switch is an electrical automatic protection switch used to prevent overwinding of wire ropes in lifting machinery. It is equipped with a heavy hammer of appropriate weight. The switch is disconnected or connected when the hook moves up and down to lift or lower the heavy hammer, thereby automatically cutting off the power supply of the winch and connecting the brake system, thereby achieving the purpose of limiting the overwinding of the wire rope and the purpose of raising and lowering the hook within a certain height.
