How to deal with 3 ton electric chain hoist motor overheating

Any machine has the cycle and time of operation, is not suitable for a long time continuous operation. Long time operation will cause mechanical damage and even accidents, but in general if the 3 ton electric chain hoist surface temperature is too high, we need to check what is the reason.
Firstly to check whether it is because the electric hoist weight is too large, beyond the 3 ton electric chain hoist rated weight. Overweight operation will make the motor over heating, overload for a long time will cause irreparable damage to the electric chain hoists for sale. Electric hoist motor is not overloaded, but still heating, should check whether the motor bearing damaged; Should also check whether the motor Work according to regulations, which is one of the reasons causing the motor heating.
When the electric hoist motor is running, brake clearance is too small, not completely disengaged, causing great friction, while the frictional heating is also equivalent to the additional load, the motor speed is reduced, then we should let the electric hoist cooling. Adjust the brake clearance before running the 3 ton electric chain hoist again. The use of electric hoist must always pay attention to the abnormal response of electric chain hoists for sale, in order to avoid accident.

The reason of electrical wire rope hoist does not work after starting

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...

Overhead gantry crane lifting instructions

The overhead crane in workshop should not use mechanical lifting, because the top of the rail is close to the bottom chord of roof truss, in addition, the volume and weight of the heavy duty gantry crane are large. Small and medium sized overhead travelling gantry crane used single mast upright integral hoisting, which can improve work efficiency, shorten the construction period, reduce high-altitude operations, the construction procedures are as follows. Erecting mast 1.The height of the mast The maximum height of the mast is the height from the ground to the roof, minus the operating space between the top of the mast to the roof panel and the height of the sleeper. Minimum height should meet the needs of lifting height. 2.Mast position Since the mast is to be erected at the center of gravity of the travelling gantry crane between the two main girders of the trolley, the trolley must be biased, and the mast should also deviate from the centre line of the plant. The deviatio...
