Electric hoist in high-tech applications

   With technology innovation,lever hoist electric hoist industry gradually improve and develop high-tech crane also been presented in the following for you to do the following detailed infrared emission electric hoist anti stayed sensor is how it works:
       Infrared emission electric hoist anti stayed sensors, infrared emission electric hoist anti stayed sensors have small, compact, sensitive, reliable, easy to install, fast, easy adjustment, saving time and labor advantages. It electrical roll cover, characterized in that:hoist and trolley the left and right ends of the roll cover fixed to a sensor, on the end face of the columnar body has the depth of the groove, groove depth of the cavity in which are inserted two pairs of transmit and receive infrared diode, external circuit through a wire connected to the center of the depth of the groove is formed with a window on the outer wall holder with the key groove of the plunger with the sliding rod is equipped with a spring plunger insertion end and a through hole depth of the groove center position of the window,wire rope winch no signal passes the closed state, the front end opened holder on the outside of the wire hole, two card holder rear end plate, with the groove on the cylinder assembly, plunger put inside the housing.
