Shell: Light aluminum alloy shell shall be adopted wich is light but hard and fit for the use in the terrible work environment with a high heat dissipation rate and all tightness design.
Inverse phase sequence protecting device: It is the special electrical installation which control the circuit not to work in case of wiring error in the power supply.
Limit switch: The Iimit switch device is installed where the weight is lifted on and off to make the motor to stop automatically so as to prohibit the chains from exceeding for safety.
24V/36V decice: It is used to prohibit the emergencies from occurring in case of the leakage in the switch.
Side magnetic braking device: This device shall realize the instant brake in case of the power dump.
Chain bag: It shall be light, handsome and durable.
Chain: The chain shall adopt the imported FEC80 ultra heat-treatable Alloy steel chain.

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.
