Overview
Explosion-proof crane is special designed for hazardous area Zone1 and Zone2 according to standard GB/T10222-2011. Due to special measures of safety the ignition of an explosive atmosphere is prevented effectively. For reliable protection every part of the crane is analyzed carefully to remove all possible ignition sources. the crane is also applied in the fields of oil drilling platforms, gas plants, sawmills, paint shops, refineries and other hazardous environments
Explosion-proof overhead traveling cranes are generally categorized into single and double girder cranes. Single girder cranes are ideal for maximizing space utilization with optimal hook approach. Double girder crane are necessary when heavier load are handled.
Feature of Explosion-proof crane
1.Compact design with standard headroom EU or low headroom EK DM hoist for maximum space utilization
2.Minimum IP55 for electrical enclosure
3.Automatic cut-off of the lifting and lowering motions at the upper and lower positions
4.Electronic overload protection connect with warning horn
5.Low Noise
