DHBK type explosion - proof electric chain hoist is improved and designed by our company on the basis of HBSQ type explosion-proof chain hoist. Using disc brake motor as power, planetary reducer decelerates. It has the characteristics of compact structure, small size, light weight, high efficiency, convenient use, reliable braking, simple maintenance and so on! Mainly used in petroleum and petrochemicals. Petrol stations, oil depots, gas production, chemical industry, military industry, chemical industry, electric power, mines, electronics, railways and other potentially fire and explosion hazardous environments. During the operation, the friction and collision of Chinese products will not produce mechanical sparks, and the gas will not be detonated in flammable and explosive places, effectively preventing fire accidents and ensuring national property and personal safety. The scope of application of DHBK type explosion-proof fast electric chain hoist:
1. The altitude does not exceed 2000m;
2. The relative humidity of the surrounding air is not more than 95% (+25°C);
3. The temperature of the surrounding medium: －5°C－－+40°C;
4. In mines with biogas mixtures;
5. In a place where there is no significant shaking and shock vibration;
6. Pollution degree: Level 3;
7. Safety category: Class II
