The double girder overhead crane is widely used in lifting 5t~50t stuff. It’s very convenient to install and operate with various functions in workshops, metallurgy,warehouses and assembly shops etc.

It is generally composed of mechanical, electrical and metal structures.

Mechanical part: it is divided into three institutions namely lifting mechanism, trolley running mechanism and big car running mechanism. The lifting mechanism is used for vertical lifting objects, and the car running mechanism is used to carry the load for transverse movement. The big car run mechanism is used to make the lifting trolley and the articles to move vertically to achieve three-dimensional space to carry and unload the cargo.

Metal structure: consists of main girders, end carriages, hoist, trolley and rails.

Electrical components: electrical equipment and electrical wiring.


It is widely used in workshops, metallurgy, warehouses ,assembly shops,industrial and mining enterprises, steel and chemical industry, railway transportation, port wharf, logistics and other departments and places.


♦  Double main girders, box-type shape

 Lifting mechanism is open type winch trolley

 Welding seams are tested by X-ray and ultrasound

 Compact structure, small volume and light weight trolley

 safty device ,anti-collision protection and crane distance controls

 Main girders Shot blasting sa2.5 after welding to release internal stresses

 Good operation performance, step less speed regulating and running smoothly

 Compact reducer motor drive, step less control, hardened gears and safety disc brake

 Maintenance platform and accessible crab facilitate maintenance of building interior fittings


The safety devicesof double girder overhead crane not only the electric  protective devices or alarm bell but other equipments are necessary to guarantee the normal operation of crane and avoid the personal casualty and mechanical damage.Such as:

overload limiter

track sweep plate

anti-collision device

 limit switch (lifting and traveling)

 bus bar protection board

 main disconnecting switch

 interlocking protection devices

 emergency stop system and motor overload protection
