Product Introduction
An Explosion-Proof Single Girder Overhead Crane is a special type of overhead lifting equipment designed for material handling in hazardous environments where flammable gases, vapors, combustible dust, or explosive atmospheres may exist. It is commonly used in industrial plants where ordinary overhead cranes may not be suitable due to explosion-risk working conditions.
This crane usually consists of a single main girder, end carriages, explosion-proof electric hoist or trolley, crane traveling mechanism, electrical control system, safety devices, and supporting components. Compared with a standard single girder overhead crane, an explosion-proof single girder overhead crane is equipped with explosion-proof motors, explosion-proof electrical components, explosion-proof control systems, and safety configurations selected according to the actual hazardous area requirements.
ZOKECRANE explosion-proof single girder overhead cranes are designed and manufactured by Henan Zoke Crane Co., Ltd., a professional lifting equipment manufacturer specializing in overhead cranes, gantry cranes, electric hoists, trolley mechanisms, and customized lifting solutions. Our manufacturing base is located in Changyuan, Henan Province, one of China’s major crane production centers. With extensive experience in crane engineering, design, and manufacturing, ZOKECRANE provides reliable crane equipment for different industrial applications and international markets.
The explosion-proof single girder overhead crane is often used with an explosion-proof wire rope electric hoist as the lifting mechanism. It runs on runway beams installed on both sides of the workshop and can provide three-dimensional material handling: lifting up and down, hoist traveling left and right, and crane traveling forward and backward. This structure is suitable for workshops, warehouses, production lines, maintenance areas, and hazardous industrial environments requiring safe and efficient lifting operations.
ZOKECRANE can provide customized explosion-proof single girder overhead crane solutions according to lifting capacity, span, lifting height, working duty, crane traveling length, control method, voltage, frequency, hazardous area classification, gas group, dust type, temperature class, protection level, installation condition, and destination country standards.
