The maintenance of electrical chain hoist

1. Electric chain hoist gear box oil. Please check the amount of oil is enough after operation start up to 500 hours, and check lubricating oil regularly after third months, refuel if lack.
2. Should set up a rain proof device when use outdoor.
3. Keep the parts of 30 ton chain hoist dry, please sail the electrical chain hoist from humid zone or high temperature zone or chemical district after operation, to maintain the performance.
4. Please lubricate the chain, high dust factory please using oil, and regularly remove in the chain, to ensure the smooth operation.
5. For a long time do not use electrical chain hoist, should do anti rust treatment and cleaning, and operation of 1-3 minutes to maintain its performance.

50 ton large-tonnage electrical chain hoist, the product is reference to the latest professional standards at china and abroad, through the pulley block ratio and motor transformation, it can lift the weight of 1 t – 50 t, lifting altitude start from 6m to 96m, working-level M3 to M6.Widely used in factories, mines, railway, port,and warehouse.It can adapt to various working condition of lifting equipment.
1.Using speed reducer reduce the speed, high transmission efficiency, low noise, compact structure, omit intermediate shaft, install easier.
2.Lifting hook has a locking device to prevent rigging accidentally slip.
3.The motor is equipped with thermal protection device, when the motor temperature is high, the device will automatically cut off the circuit in order to protect the motor.
4.High safety and reliability: the optional limit load protection device, it can avoid overloading.

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 additi...

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...

Working principle of electric hoist motor

The DC disc brake of the electric  hoist motor  is mounted on the end cover of the motor shaft. When the  crane duty motor  is connected to the power supply, the electric hoist motor works at the same time. Because of the electromagnetic suction, attracts the armature and the compression spring, brake disc on the armature end cover is disengaged, crane duty motor running. When the power is turned off, the electromagnet electric hoist motor without magnetic force, the spring pushes the armature to the brake disc, the effect of friction torque, braking the motor stop immediately; our factory also produces the corresponding KDA050 dual speed motor.  Electric hoist motor  power supply by the rectifier in the motor junction box, and below 3 kilowatts to 4 kilowatts and above AC220V-DC99V, AC380V-DC170V (special time can also be in accordance with the requirements of the factory design such as (DC24V)),  KDA050  series electric hoist motor , can move qu...
