"Mine chain electric hoist," by the national anti-explosive electric products quality supervision and inspection center review, model to determine the type of BHH.
Yellow Crane production of the mine chain electric hoist 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", 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 dIICT4 and dIIBT4 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.Issued by the national technical supervision administration of licenses.This product is suitable for installation on the orbit lifting heavy objects.Ensure safe enough.
Mine chain electric hoist products must strictly comply with the conditions stipulated in the "manual" to use.
Second, the scope of application
1, mine chain electric hoist series product structure is compact, light weight, small size, large lifting capacity.When in charge of the plant have a dust explosive mixture, on the premise of security is to improve the 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) with methane explosive mixture, without obvious damage of the insulation gas or steam
Such as the actual conditions of use does not accord with the above, indicate when you order it.
