What is a Gantry Overhead Crane?
Gantry Overhead Cranes Imagine a bridge that moves on wheels, carrying a lifting mechanism. That’s essentially a gantry overhead crane! It’s a type of crane that runs on tracks or rails, allowing it to move heavy loads both horizontally and vertically within a defined workspace.

How it Works:
- The Bridge: The main structure that spans the workspace, moving horizontally on the tracks.
- The Trolley: Travels along the bridge, carrying the lifting mechanism (hoist).
- The Hoist: Lifts and lowers the load using a system of cables and pulleys.
Types of Gantry Overhead Cranes:
- Single Girder: Uses a single main beam, typically for lighter loads.
- Double Girder: Employs two main beams, providing greater strength and capacity for heavier loads.
Where are they used?
Gantry overhead cranes are widely used in various industries, including:
- Manufacturing: Lifting and moving heavy machinery and components.
- Construction: Handling building materials and equipment.
- Warehousing: Loading and unloading trucks and moving goods within warehouses.
- Shipyards: Loading and unloading cargo from ships.
Key Advantages:
- Versatility: Can handle a wide range of loads and tasks.
- Efficiency: Improves productivity by speeding up material handling processes.
- Safety: Reduces the risk of injuries to workers by minimizing manual handling.
