防爆电动葫芦和一般的电动葫芦有很大的区别，首先是材料和结构，其次是防爆的全封闭式结构，还是就是外壳以铝青铜合金和铍青铜合金所制成这种材质的防爆电动葫芦具有防爆作用，在特殊的场所里敲击、摩擦都不会产生火花，防爆电动葫芦价格当然也要比普通钢丝绳电动葫芦要贵上好多。 The explosion-proof electric hoist is very different from the general electric hoist. First, it is material and structure, the second is the completely closed structure of explosion-proof, or the explosion-proof electric hoist, made of aluminum bronze alloy and beryllium bronze alloy, has the function of explosion-proof electric hoist. It will not produce in a special place. The price of spark and explosion-proof electric hoist is certainly much higher than that of ordinary wire rope electric hoist.
