The no-load operation of the electric hoist should be in place

In general, the maintenance work of electric hoists is divided into maintenance during installation and maintenance during use after installation. Whether installing a new electric hoist or removing it after installation, in order to ensure normal operation, it is necessary to carry out no-load operation.

Power on work cannot be carried out before installation and debugging. Power on and no-load work can only be carried out after installation and debugging are completed. When operating an electric hoist, static load testing is often required to ensure that the nominal indicators can meet the standards. The general approach is to increase the set rated charge, conduct a test load, and observe the use of the electric hoist. It is necessary to identify its compliance value and rated load at any time, in order to determine whether the electric hoist meets the requirements for use. When starting the test, it is also necessary to check the transmission part of the accessories. Check if the electrical connections are reliable and stable. The rated compliance set during normal use is not allowed to exceed. When starting installation and debugging, one should carefully check the limits within the system. If the hook is raised to the proposed limit, the distance between the shell of the hook and the drum should exceed 50 millimeters. When the hook is lowered, the drum should be equipped with a safety ring. The steel rope wrapped around it should be laid at least twice. If two electric hoists are pressed at the same time, they should not be pressed in the opposite direction. Special attention should also be paid when performing power outage operations. Only when the electric hoist returns to the designated position can the power outage operation be carried out. When technicians carry out maintenance work on the electric hoist, if any abnormalities are found in the operation of the electric hoist, they should promptly check the various values during the operation of the electric hoist, and then conduct technical analysis to ensure that the rated load is below the required load for debugging. At the same time, it is necessary to ensure the cleanliness of the oil and ensure that the oil is clean, free of impurities, flat, and has a moderate amount of oil during the operation of the electric hoist.

Electric hoists are indispensable for the transportation industry, so scientific debugging work must be carried out before the application of electric hoists. Subsequently, when repairing electric hoists, attention should be paid to the inspection and maintenance of brakes and reducers.
