Troubleshooting and Diagnostics rope hoist

After the starter rope hoists , motor does not turn , can not lift heavy objects reasons
( 1 ) excessive overload
( 2 ) lower voltage than liftech winch hoist the rated voltage of more than 10%
( 3 ) The motor is faulty, broken wire or poor contact
( 4 ) the rear brake wheel and cover rust killed , brake wheel tied up
( 5 ) Motor sweep chamber
Workaround
( 1 ) does not allow overloading
( 2), the voltage returns to normal
( 3 ) Maintenance of electrical and wiring
( 4 ) Remove the brake wheel , cleaning corroded surfaces
( 5 ) the occurrence sweep chamber is mainly due to severe wear on the motor shaft support ring , rotor core axial displacement or displacement of the stator core , need to be removed liftech winch snatch block to replace the support ring , so that there is a uniform gap between the stator and rotor cone, each side is 0.35-0.55 mm wire rope hoist manufacturer or return repaired

Winding lifting equipment

Single rope winding hoist is a hoist earlier onset of its working principle is: the end of the rope to liftech cheap wire rope hoist enhance the two opposite directions , respectively, and fixed on the winding hoist two rolls , and the other end to bypass the derrick days on the wheel are connected with two lifting containers. Thus, by changing the direction of rotation of the drum motor can be hoisting rope winding and pine were put on two rolls , in order to achieve or enhance the decentralization of container to complete the task of enhancing purposes . Currently, single rope liftech winch hoist winding hoist use is more common in our mines . Single rope winding hoist is a hoist cylindrical roll , depending on the number of reels can be divided into two double rolls and single rolls .
