Explosion-proof Single Girder Crane

Weihua Crane is professional material handling equipment manufacturer and servicer with largest production in global. Provide you with overhead crane, gantry crane, electric hoist, etc. of safe, reliable and efficient crane solutions and services.


Explosion-proof Single Girder Crane has the characteristics of strong explosion-proof, compact structure, good rigidity, safety and reliability. The main components including: crane traveling mechanism, electrical system, bridge, explosion-proof electric hoist.
Crane traveling mechanism with explosion-proof motor
Explosion-proof Single Girder Crane use conical explosion-proof rotor brake motor, standard motor insulation class is B, protection class IP44, it also can be made to F or H insulation class, IP54 or IP55 protection class according to condition requires, proof grade is divided into ExdⅡBT4 and ExdⅡCT4. Motor has features with good heat dissipation, long life, safe and reliable, strong explosion-proof ability, etc.

Crane traveling mechanism with explosion-proof motor          Explosion-proof Wheel group
Wheel group is of 45 # steel forging molding, through precision machining, heat treatment hardness of 300 ~ 380HB, hardened layer at a depth of not less than 15mm 260HB. When the explosion level is ExdⅡCT4, the traveling mechanism spend fire processing, such as wheels welded stainless steel or bronze.
Electrical explosion protection system
Explosion-proof electrical device with sealed enclosure, explosion-proof level is ExdIIBT4 or ExdIICT4. Electrical components inside of the Explosion-proof control box adopt high quality, good reliability and long life Siemens low-voltage electrical components to minimize the times that explosion-proof box open due to electrical fault.
Explosion-proof control boxControl button box
In addition to set electrical interlock between the opposite directions traveling contactor in the control box, between the buttons of the button control box is also provided with mechanical interlock to prevent the occurrence of short circuit caused by misuse. The control circuit voltage is AC 36V safe voltage. When the cabin operates, cabin interior switches, junction boxes, buttons, boxes and bells, etc. are both explosion-proof. Other safety protection systems such as fire limit, travel switch are also explosion-proof.
