Overhead Bridge Crane Design
The overhead bridge crane has simple structure, mainly encompassing main beam, end beam, hoist trolley, crane traveling mechanism and electric control system. The main beam, end beam, platform and rails constitute the bridge. According to your specific lifting requirements, the crane girder can be designed into single beam and double beam. The main beam generally adopts box structure which has easy manufacturing process, convenient assembly, strong versatility and rigidity. With respect to different lifting capacities, load types and environmental conditions, the crane can be equipped with pendant control, wireless remote control or cabin control.
As the most critical part of overhead bridge crane, trolley mechanism will directly affect the performance of the equipment. It consists of two main parts, lifting mechanism and running mechanism. According to your practical needs, various lifting tools can be outfitted, such as hook, grab, electromagnetic chuck and carrier-beam.
The crane traveling mechanism is mainly composed of supporting device and drive device. The crane can be designed into top running and under running type based on certain ceiling height. Besides, a range of protection devices can be equipped on your requests. To know more about overhead bridge crane design, please contact us now.

Usages of Wire Rope in Overhead Bridge Crane
As the crucial component of electric hoist and overhead bridge cranes, the usage of wire rope have a directly impact on bridge crane safety.
- The wire rope must keep in a good lubrication state.
- Check the fix condition in the end of the rope routinely.
- The wire rope should be scraped when reaching national retirement standards or occurred three situations such as dense crack, wear out, or break off the rope.
Adjustment&Repair of “Track Biting” of Crane Running System
When the overhead bridge crane travel normally, the wheel flange and rail should keep distance. When the wheel flange and rail are squeezed up, the friction between them would be enhanced greatly which caused abrasion, and this phenomenon is called “track biting”.
- Measure and adjust the verticality, parallelism and straight factors of the wheels.
- When there are obviously clear trace at the side of steel rail, there must appears damage.
- When the crane is travelling, there exists obviously change between the wheel flange&steel rail in a short distance.
- Calculating the span length of the rail and inspecting the problem.
- Clearance of rag (if exists), and clean up the components.
- Change the wheel if it is of severe damage.
