Introduction of explosion proof electric hoist
The explosion-proof electric hoist is a kind of light and small lifting equipment. The explosion-proof electric hoist has light weight, small volume and large lifting capacity. When the workshop is filled with explosive mixture, it is a favorable tool to improve working conditions and labor productivity on the premise of ensuring safety. It is also a necessary mechanical equipment for production.
The explosion-proof form of the explosion-proof lifting equipment designed and manufactured according to the explosion-proof standard is "flameproof". The exposed explosion-proof parts of the hoist are made of special non sparking materials, so the explosion-proof performance is safe and reliable.
The product has passed the explosion-proof performance test of the explosion-proof electrical product quality supervision and inspection center of the Ministry of mechanical industry, and issued the explosion-proof certificate.
The explosion-proof electric hoist is suitable for class I explosion-proof coal mine non mining working face places and class II explosion-proof places with class IIa, IIB, IIC, temperature group T1-T4 combustible gas or explosive gas mixture composed of steam and air. The working environment temperature is - 25 ℃ ~ 40 ℃, suitable for indoor use; When used outdoors, protective devices should be added.
