According to the provisions of GB3836.1-2000 "Explosion proof Electrical Equipment for Explosive Gas Environments Part 1: General Requirements" and GB3836.2-2000 "Explosion proof Electrical Equipment for Explosive Gas Environments Part 2: Explosion proof Type" d ", when the motor and electrical appliances are explosion-proof and the explosion-proof level is Exd Ⅱ CT4, the operating mechanism shall be treated with fireproof flowers. The whole machine complies with the provisions of JB/T10222-2001 "Explosion proof Steel Wire Rope Electric Hoist", with explosion-proof levels of Exd Ⅱ BT4 and Exd Ⅱ CT4 respectively. This machine can be used separately with the fixed suspension track in the workshop, and can also be used in conjunction with LXB explosion-proof electric suspension single beam, LB explosion-proof electric single beam, and explosion-proof hoist double beam. Its lifting capacity is 1-32t. The working environment temperature ranges from -20 ℃ to 40 ℃. Huarui's explosion-proof products are divided into three categories: in addition to the gas explosion-proof mentioned above, there are also dust explosion-proof and coal safety explosion-proof, which are suitable for different explosion-proof places.
