The main products of chain hoists Explosion-proof chain hoists, chain hoists 1: aluminum bronze, beryllium as a rough chain hoists manufacturers, explosion-proof chain hoists chain hoists H62 copper alloy shell with proof chain hoists used in easy Burning explosive occasion hoists prices, such as chemical, offshore and other operations. 2. Explosion-proof chain hoists rotating gear after high-temperature heat treatment to achieve the gear, according to a high wear resistance. Explosion-proof chain hoists bracelet pull small, light weight, easy to carry, beautiful appearance, small size, durable. 3. proof hoists work principle: Hands chain drag chains, bracelets wheels began to turn, friction ratchet brake seat (to be pressed into one) co-rotating, five major axis will rotate sprocket teeth, four teeth of the minor axis and flowers keyhole gear. Thus hoists 0.5t, lifting devices on spline sprocket holes on the drive gear lifting chain, lifting heavy objects smoothly. Explosion-proof chain hoists rating is how much? Hoists explosion proof grade is proof grade is dⅡAT2 to dⅡAT4. d flameproof representative. II on behalf of Class II proof that Plant Explosion. C can be used for C-level representatives of the Ex area, which is available for the most dangerous areas. Temperature class T4 representatives from T1-T6 chain hoists, to T6 is the highest. Explosion-proof chain hoists can be widely used in petroleum, petrochemical, gas stations, oil depots, gas, chemical, military, power, mining, electronics, railways, and other potential fire and explosion hazard environment, mutual friction in the job impact of the product does not produce mechanical sparks, effectively prevent fire accidents, ensure that state property and personal safety.
