Overhead rail crane is a functional lifting device. It has wide application in factory, warehouse, workstation, material handling yard, construction site. With various types, customers can choose suitable one for work.
For girder, the crane includes single girder crane and double girder crane; for lifting capacity, overhead rolling crane has small shop bridge crane and heavy duty crane; for place, it includes warehouse crane, workstation crane, factory crane; for design, it has top running bridge crane and underslung bridge crane. Under-traveling crane is particularly designed for factory with restricted height. It can save much area.

Single girder crane VS double girder crane
Single girder rail crane is one kind of light duty crane. It is equipped with electric hoists to increase operation area and improve working efficiency. It is widely used in steel plant, cement plant, power plant, mine industry, food industry, chemical industry, shipyard, stone yard and warehouse.
Parameters:
- Load capacity: 1-25t
- Span: 7.5-31.5m
- Lifting height: 6-30m
- Lifting speed: 0.3-8m/min
- Hoist running speed: 20m/min
- Crane running speed: 20m/min
- Work duty: A3, A4
Double girder rail crane is heavy duty crane. It is used to transport,assemble,load and unload goods in mine, port, factory, workshop, warehouse and goods yard,etc. The open direction is divided into parallel and vertical with main beam and the grab can be double or four wire rope, mechanical or electric type according to different work duty and materials. Double girder crane has advantages as following:
1. Strong beams: The crane beams are of welded construction,this result in lower dead weight with a high degree of vertical and horizontal rigidity and smaller wheel loads.
2. End carriage: Crane travelling system,motor-reducer wheel driven system! Motor used soft start motor which result in very stable starting!
3. Durable performance and high efficiency,
4. Modern cabin control with air conditioner to separate operators from harsh environment,
5. Electrical equipment: Electric system are Siemens brand or Schneider brand,
6. Long service lift with a low-maintenance!
Parameters:
- Load capacity: 5-450t
- Span: 10.5-31.5m
- Lifting height: 6-24m
- Lifting speed: 2.1-11.5m/min
- Trolley running speed: 27-40m/min
- Crane running speed: 42-75m/min
- Work duty: A3-A7

How to operate overhead rail crane safely?
Avoid sharp contact between trolley or between trolleys and stops.
Do not use the primary upper limit device as an operating limit. Use other operational limits if they are available.
Do net lower the load beyond the point where less than two wraps of wire rope remain at each anchorage on the drum, unless a lower limit device is provided, in which case no less than one wrap of wire rope shall remain at each anchorage on the drum.
Activate the manual warning device before starting the bridge or trolley travel motion of the crane, and intermittently during travel of the crane when approaching people in the travel path of the load.
Do not engage in any activity that will divert your attention.
Do not lift, lower, or transport a load with the crane or hoist until all personnel are clear of the load and the load’s path.
Verify that the load, crane and hoist will clear all obstacles before moving or rotating the load.
Do not move loads over personnel.
