What Is a Top Running Bridge Crane? Benefits, Design, and Industrial Uses
If you are exploring different types of bridge cranes, you’ve likely come across the term “top running bridge crane.” This design is widely used across industries that require reliable, high-capacity, and long-span lifting systems. But what exactly is a top running crane, and when should you choose one?
In this article, Nybon Machinery explains the structure, advantages, and common applications of top running bridge cranes—plus how they compare to under-running cranes.
What Is a Top Running Bridge Crane?
A top running bridge crane is a type of overhead crane where the bridge girder(s) ride on top of the crane runway beams. These runways are usually mounted on columns integrated into the building structure or on free-standing supports.
The hoist and trolley run along rails placed on top of the bridge beams, enabling higher load capacity and more lifting height.
How a Top Running Crane Works
-
The end trucks ride on top of the runway rails.
-
The bridge beam(s) span the width of the building or work area.
-
The trolley hoist moves laterally on rails atop the bridge beam.
-
The system provides three-axis motion: up/down (lifting), left/right (trolley), and forward/backward (bridge).
Top Running vs Under Running Crane
| Feature | Top Running | Under Running |
|---|---|---|
| Mounting Style | On top of runway beams | Suspended from runway beams |
| Lifting Capacity | Higher (up to 200 tons) | Limited (typically under 10 tons) |
| Span Range | Wide span possible (up to 40m+) | Narrow to medium span |
| Hook Height | Higher lifting height achievable | Slightly reduced due to suspension position |
| Structural Support Needed | Requires strong columns or building support | Can be used with lighter building structure |
| Application | Heavy-duty industrial settings | Light-duty or low headroom areas |
Advantages of Top Running Bridge Cranes
✅ 1. High Load Capacity
Top running cranes are the best option when lifting heavy equipment, machinery, steel coils, or containers, with capacities reaching 200 tons or more.
✅ 2. Better Hook Height
Because the hoist rides on top of the girder, the hook can get closer to the ceiling—allowing maximum lifting height in tall structures.
✅ 3. Wider Span Capabilities
Ideal for large factories, shipyards, or steel mills with wide working areas.
✅ 4. Easier Integration of Attachments
Top running cranes are ideal for integrating lifting magnets, grab buckets, or automated systems for heavy process lines.
✅ 5. Greater Durability
With larger wheels and a more robust runway, top running cranes have longer service life and are better suited for continuous use.
