Maintenance

In order to ensure the reliability and service life of the electric hoist, the hoist must be lubricated and maintained regularly: 1. For newly installed, overhauled and reused for more than one year, the electric hoist should be tested according to the relevant installation test run before use; 2, in the process of use to carry out daily inspection, monthly inspection, annual inspection; 3, should pay attention to the use of wire rope, maintenance, and scrap; 4, for each inspection to have a written detailed registration record and take measures. 5, during maintenance, replacement parts should be the same as the original material and performance; 6, structural parts in welding, operation and use of materials should meet the quality standards of the original structure; 7, electric hoist in the working state, is not allowed to carry out maintenance; 8, the above inspection items refer to the relevant provisions and requirements.

The gap between the conical rotor and the stator of the motor is too small to collide (called "sweeping bore")

The gap between the conical rotor and the stator of the motor is too small to collide (called "sweeping bore")

The main reason for the treatment method is that the factory products are not allowed to "sweep the bore". The main reason for the occurrence of "sweep the bore" is: the support ring on the motor shaft is seriously worn, the rotor core is axially displaced, or the stator core is displaced to replace the support ring, so that there is a uniform gap between the cone surfaces of the stator and rotor, with each side being 0.035~0.55mm (small gap for small motors) or sent back to the manufacturer for repair.
