1. Key Components
✔ Single Girder (Main Beam) – Typically an I-beam or box-type steel structure (load capacity: 1–20 tons).
✔ End Trucks – Wheeled frames that move along runway rails.
✔ Hoist & Trolley – Electric chain hoist or wire rope hoist for lifting.
✔ Runway Rails – Installed on building columns or freestanding supports.
✔ Control System – Pendant control, remote, or cabin-operated.
2. Types of Single Beam Bridge Cranes
A. Top-Running vs. Under-Running
Type
Description
Max Capacity
Use Case
Top-Running
Runs on rails mounted on top of runway beams.
1–20 tons
Heavy-duty industrial use
Under-Running (Underhung)
Suspended from ceiling/runway beams.
1–10 tons
Workshops with low headroom
B. Manual vs. Electric
Manual Push Bridge – Operated by hand (for light loads, infrequent use).
Electric Travel – Motorized movement (for frequent, heavy lifting).
C. Freestanding vs. Building-Mounted
Freestanding – Supported by floor columns (no building reinforcement needed).
Building-Mounted – Attached to existing roof structures (requires structural checks).
3. Advantages of Single Beam Bridge Cranes
✅ Lower Cost – Cheaper than double girder cranes.
✅ Space-Saving – Requires less headroom.
✅ Easy Installation – Modular design for quick setup.
✅ Versatile – Compatible with chain hoists, wire rope hoists, or vacuum lifters.
