Explosion-proof electric hoist During use, it can be fixed to a suspension point or hung on an I-beam. So can it be directly hung on an I-beam? If it is repeatedly used during operation, will it derail? Because the track is fastened with screws, the screws will loosen with long-term use, and derailment may occur during use. Can we prevent this phenomenon?
Yes, there is a new type of electric hoist anti-derailment device for lifting equipment. These devices include I-beams, active cars, drive cars, reducers, active wheels, and passive wheels. When using engineering steel, install a compromise device to make the project safer.
What are the explosion-proof gases for electric hoists?
The explosion-proof grades of electric hoists are DIIBT4 and DIICT4 respectively. The exposed explosion-proof components of this hoist are made of special spark-free materials.
Explosion-proof gases for explosion-proof grade DIIBT4 include acrylonitrile, acrylonitrile, ethylene, butadiene, ethylene, hydrogen sulfide, dimethyl ether, diethyl ether, dibutyl ether.
Explosion-proof gases for explosion-proof grade DIIBT4 include hydrogen, water-containing gases, and acetylene.
It can be used in ports, power, steel, shipbuilding, petrochemicals, mining, railways, construction, metallurgical chemicals, automobile manufacturing, plastic machinery, industrial control, roads, large-scale transportation, pipeline auxiliary, slope tunnels, well management and protection, maritime rescue, and ocean engineering.
Explosion-proof electric hoist Debugging
When debugging a wire rope electric hoist, the debugging of static load and dynamic load should be carried out in accordance with the safety regulations for special equipment.
Friendly reminder
1. The explosion-proof marking of the electric hoist is D BT4 and D CT4, which is suitable for places with explosive gas mixtures formed by flammable gases, vapors, and air of grade A, B, and C, and temperature group T1-T4.
2. Oblique lines are prohibited, overloading is prohibited, strangulation is prohibited, and personnel are prohibited from staying at the station during the operation of the explosion-proof electric hoist.
How to view the explosion-proof grade of the explosion-proof electric hoist? The explosion-proof marking can be seen. D BT4 is a Class III explosion-proof, and D CT4 is a Class IV explosion-proof, suitable for places with explosive gas mixtures formed by flammable gases, vapors, and air of grade A, B, and C, and temperature group T1-T4. For example: ports, mines, biomass power generation, chemical industry, natural gas, natural gas pipelines, and ocean transportation.
