Electric hoist control box work environment requirements

   Electric hoist electric hoist control box is to control the operation of the main control mechanism.hoist and trolley Mainly by the transformer, box, terminals, contactors and other components. Electric hoist control box chain with a machine quality AC contactor, the load and instantaneous overload are much improved, but the working environment of the control box there is a certain requirements before normal use.
       Control box work environment requirements:
1, ambient air temperature: -20 ℃ ~ +40 ℃.
2, the air relative humidity: lowest average humidity of 90%, with an average temperature of 25 ℃, and also taking into account variations due to temperature control box on the lift hoist  Cream.
3, in the workplace should be no violent oh one and vibration.
4, in the absence of an explosion in the use of micro-media, and medium without corrode metal and damage the insulation of gas and dust (including the point of dust).
5, no more than 2500 meters above sea level to use.
       Electric  rope hoist  control box can also be provided upon request multi-core cables of different lengths and flashlight door, opened the lid of the control box, the removable from hinge, user-dark group Aung, maintenance, control box electronics chain has to take and mechanical linkage, so that the same group of two contacts can not be connected to the circuit; each hoist control box is equipped with electrical schematics, wiring terminals are clearly consistent with the schematic diagram number, easy to use almost maintenance, wiring.
