"Mine explosion-proof ring chain electric hoist" product details:
Yellow crane explosion Production of mining explosion-proof chain electric hoist used in explosion-proof motor, explosion-proof electrical equipment, such as whether the factory design and manufacture or produced by production, are based on national standard GB3836.1-2010 "explosive environment with equipment - part 1: general requirements and GB3836.2-2010" explosive environment with equipment - part 2 flameproof "d", "regulations and JB/T5317.2-1991" ring chain electric hoist technical conditions "made explosion-proof marks for ExdI mine explosion-proof chain electric hoist, this product with the explosion-proof motor, explosion-proof electrical appliances are made the flame-proof certification issued by the state and the period of validity of MA certificate.This product is suitable for the installation of lifting heavy objects in orbit, ensure safe enough.This product must have for all electrical appliances fittings AnBiao certificate in the period of validity.This product is suitable for the coal mine (not a single face) used in the work environment, it is strictly prohibited to lifting, overload is strictly prohibited to use! 

Mine explosion-proof chain electric hoist must strictly comply with the conditions stipulated in the "manual" to use.
      
     
Second, the scope of application
1, this series mining explosion-proof chain electric hoist compact structure, light weight, small size, large lifting capacity.When the underground work environment filled with explosive mixture, on the premise of security is to improve working conditions, is a powerful tool to improve labor productivity, and thus become the necessary machinery and equipment in reasonable technological process.
2, the use of the environment
(1) at an altitude of 2000 meters
(2) the ambient air temperature is not higher than + 40 ℃, no less than 25 ℃.
(3) power grid volatility in plus or minus 10%.
(4) the relative humidity is not more than 95%, can prevent the drop of water.
(5) in the coal mine with methane explosive dangerous gas (not a single face).
Such as the actual conditions of use does not accord with the above, indicate when you order it.
