rope hoist lifting heavy gauge safety device

  Wire rope hoist  overload limiter - When lifting heavy gauge, eccentric bracket shell around the hoist side panel positioning mandrel rotates counterclockwise in to a preset distance proximity switches, proximity switches off lifting contacts Wire package circuit, cutting off  rope hoist lift hoist  power, the  rope hoist stops running, play overload limiting role in achieving the safe operation of the crane, lifting heavy gauge safety devices to improve the reliability and security.

      Countries in this year's increase in the use of special equipment installation of the new requirements, all of the installation of all  rope hoist overload limiter.  rope hoist overload limiter, balanced pulleys mounted  rope hoist  rope hoist  housing unit and between the end plates,  rope hoist housing end plate at one end with a positioning mandrel and the stopper plate, positioning mandrel fitted with a shaft extension header eccentric bracket, balancing roller device hanging on one end of the eccentric shaft extension holder head, with the lower holder of the eccentric pin, the eccentric side of the bracket is provided with a supporting plate, the support plate section be equipped with a proximity switch, an eccentric bracket overhanging the center and the eccentric shaft positioning bracket spindle hole center-biased 3 mm.
