Today, one of the main components Detailed hoist electric hoist control box, look hoist control box structure : control box by a transformer box, contactors, terminal blocks and other components of electric chain hoist control box using machines with high-quality AC contactor , the load and momentary overload are greatly improved, can get better, more suitable for frequent operation of lifting appliances needed ; protection of high quality cold rolled steel sheet stretch forming , electrostatic spray . Different lengths are also available sealed bearing upon request and multi-core cables flashlight door ; After the control box lid opened, detachable from the hinges , user-friendly installation and maintenance ; control box has to take the electrical and mechanical interlock chain , so that the same two groups of contacts can not be simultaneously connected to the circuit ; each control box is equipped with electrical wind power bearing schematics, wiring terminals have clearly consistent with the schematic number , user maintenance, wiring.
The following is a hoist control box work conditions :
1 ambient air temperature is -20 ℃ ~ +40 ℃;
(2) Relative humidity: lowest average humidity is 90 %, while the average minimum temperature for the month was 25 ℃, and taking into account the temperature changes in the surface of the product Cream ;
3 workplace should have no violent shaking and vibration of the place ;
4 In the absence of explosive medium, the medium does not corrode metal and damage the insulation of gas and dust ( including conductive dust ) ;
5 not more than 2500 meters above sea level ;
