Explosion-proof electric hoist has explosion-proof galvanized steel wire rope electric hoist and explosion-proof chain electric hoist, screw jack manufacturers each and have different application fields. Mining explosion-proof ring chain electric hoist needs to reach the corresponding specifications, can be applied in stone mining, the actual following:

1. Mining explosion-proof ring chain trigonot conforms to GB3836.1-2010 "Explosion-proof electrical equipment for Explosive Gas Environment - Part 1: General Requirements" and GB3836.2-2010 "explosion-proof electrical equipment for Explosive gas environment - Part 2: 12476.1-2000 Electrical equipment for use in combustible dust environments - Part 1: Electrical equipment protected by enclosures and limited surface temperature - Part 1: Technical requirements for electrical equipment.

2. Hydraulic jack manufacturers according to the application of regional planning for the processing plant with explosion-proof dII and dI.

3. Mine explosion-proof ring chain trigonella can be used independently with fixed fixed suspension rail under coal mine.

4. The weight of mining explosion-proof ring chain trigram is 1T-10T, and the working temperature is -20℃-40℃.

5 BHH series products explosion-proof ring chain electric hoist key is suitable for the mine shaft 660V switching power supply, hydraulic jack price by the motor. The hoisting organization consists of three parts. The motor adopts YBEZ mine explosion-proof cone braking motor, which has the characteristics of large shaft load and instantaneous braking system when power is turned off. After the motor is slowed down by the three-level transmission gear, it can promote the lifting and hoisting of the sprocket chain. The drive chain lifts the lifting hook. Load tests should be carried out to ensure that all kinds of technical indicators meet the requirements. In general, the load test can be carried out in the form of increasing the positive charge of the rated value. The staff needs to check the operation of the electric hoist, so as to establish whether it meets the requirements. In the completion of the inspection, it is necessary to check whether all parts of the transmission system are normal and check whether the connection of household appliances can be stable.
