Mainly because of the hoist does not reach to the rated operating voltage, there are generally 3 kinds of situations:
1.Find out whether the power supply system supply power to wire rope electric hoist, generally used test pencil, such as no power supply;
2.The main control circuit of the wire rope electric hoist is damaged, the line is broken or the contact is bad, can also let the hoist motor not be electrified. This situation, need to overhaul the main control circuit. When maintenance, in order to prevent missing phase to burn the motor casused by the main control circuit supply power to three-phase motor, or hoist motor suddenly operate and cause danger, must disconnect electrical wire rope hoist motor from the power supply, only supply power to the main control circuit. Then start and stop switch, check and analyze the working condition of the electric appliance and the line, repair or replace the failed electric appliance or line. When the main control circuit is confirmed, the test can be re run.
3.Hoist motor terminal voltage than the lower 10% than the rated voltage, motor starting torque is too small, the gourd lifting real goods, and unable to work, inspection, with the table or voltage meter measuring motor input voltage, due to low voltage, the motor can’t start, need to wait for system voltage recovery normal after using the wire rope electric hoist. Sometimes, hoist motor voltage is normal, and hyacinth does not work, the need to consider other reasons, for example: motor burned, maintenance when the need to replace the motor; gourd is not a long time, poor maintenance, etc. the brake wheel and the end cover of rust, starting braking wheel off, motor only emit the sound, turn up, Hulu doesn’t work. At this time, should unload the brake wheel, surface rust cleaning,and then re test; serious motor sweep chamber, the motor does not rotate, found this situation, should stop using, we must overhaul or replacement of the motor, in order to guarantee the normal operation of the hoist. In the production of overloading is strictly prohibited the use of electrical wire rope hoist, when the goods are excessive overloading, gourds hanging motionless air motor only issued sound, and does not run, severe electrical burn, and even cause accidents, at this time should immediately stop, reduce the goods, enables the gourd in the rated power.
