Understanding Bridge Crane Fundamentals
Bridge cranes, also known as overhead traveling cranes, are essential material handling equipment in diverse industries. They consist of a hoist trolley that moves along a bridge structure spanning parallel runways. This configuration enables the lifting, lowering, and horizontal movement of heavy loads. The crane’s operation is controlled by an operator, using either manual, wired pendant, or wireless controls. Bridge cranes are crucial for efficient and safe material handling in factories, warehouses, and construction sites. The selection of a suitable bridge crane from manufacturers like those found on www.cranesdq.com depends on careful consideration of several factors.

| Crane Speed | 3-30 m/min | 42-75 m/min |
| Work Duty Class | A3-A5 | A3-A7 |
| Headroom | Lower | Higher |
| Cost | Lower | Higher |
Types of Bridge Cranes
Several types of bridge cranes cater to diverse industrial needs. These variations primarily concern the bridge structure, trolley configuration, and overall design. The following table highlights the key differences between common bridge crane types.
| Crane Type | Bridge Structure | Trolley Configuration | Applications | Advantages | Disadvantages |
|---|---|---|---|---|---|
| Single Girder | Single beam | Single trolley | Light to medium-duty applications | Cost-effective, easy to install and maintain | Lower lifting capacity, shorter spans |
| Double Girder | Two beams | Single or double trolley | Heavy-duty applications, longer spans | Higher lifting capacity, greater headroom | Higher cost, more complex installation and maintenance |
| Top Running | Any | Top of the beams | High headroom applications | Greater lifting height, easier maintenance | Less efficient use of building height |
| Under Running | Single beam | Bottom of the beams | Low headroom applications | Maximizes floor space | Lower lifting height |
| Box Girder | Box-shaped | Top running | High capacity, long spans, free-standing structures | High strength, high hook height, space saving | Higher initial cost |
| Truss Girder | Truss-shaped | Top running | High capacity, long spans | High strength, good for long spans | More complex design |
Bridge Crane Applications in China
