Double girder overhead crane is composed with double girder frame, crane traveling end truck, and the top running trolley with lifting and travelling device. The motors, reducers and brakes in this model crane lifting and traveling mechanism are separate parts, which makes the crane higher working duty from A3~A6 (ISO) and faster lifting and traveling speeds.
The cranes standard speeds are adjustable, which allow the crane adjust its speed under  10 grades speeds. It could move very slow which makes it possible to do very accurate works.

This model overhead crane is designed under GB regulation, passed ISO, CE certification.
The crane lifting and travelling speeds are steady and accurate.




Safety feature: 
1. Overload protection in the event of overload, the hoist unit switches off and only the lowering motion is possible
2. Long and cross travel limited by means of preliminary and final limit switches or infrared anti-collision device
3. Anti-falling protection for the Three-in-One electric motor of trolley and crane prevents from accidental falling
4. All movements can be switched off by actuating the emergency-off switch at the control station via a main contact
5. High quality long time bearing polyurethane materials buffer fixed at the end of trolley travelling and crane travelling to prevent over traveling
6. Safety hook latch used for avoiding the lifted material out off from the hook
7. Audible and visual alarm device to inform the person stay near by the travelling crane
8. Rain Cover for lifting mechanism of outdoor cranes, electric cabinet and driving mechanism
9. Protective earth conductor is fitted as standard
10. Voltage lower protection system
11. Current overload protection system and more (contact with us more details)
