The use of hoists before lifting a rule check all parts must be intact, transmission parts and lifting the chain oiled, idling normally. 2 not allowed to use heavy hook hook hook tip. 3 lifting chain is not twisted and knotted, double chain hoists under hook assemblies can not flip. 4 hook should focus on heavy vertical line, to prevent heavy tilt, flip. 5 Operation First test should be suspended, when after heavy off the ground, such as in normal operation, reliable braking can continue lifting.

Do 2 sets of 10 and above with hoists while lifting heavy objects. 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, T6 is the highest reach. 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 environments warranty chain hoists, in the job the product does not produce mechanical friction sparks strike effectively prevent fire accidents, ensure that state property and personal safety.
