Overhead cranes and underhung cranes are two common types of lifting equipment used in various industries. While both serve the purpose of moving heavy loads, there are key differences between the two. Let's compare overhead cranes and underhung cranes to understand their distinct characteristics and applications:

1. Configuration and Mounting:

• Overhead Cranes: These cranes are typically mounted on support structures that are installed on the building's columns or beams. They feature a bridge that spans the width of the working area and travels along elevated runways.
• Underhung Cranes: These cranes are suspended from the building's roof structure using end trucks and are designed to run on lower flanges or tracks. They hang below the supporting structure, allowing for maximum floor space utilization.

2. Load Capacity:

• Overhead Cranes: They are capable of handling heavy loads, ranging from a few tons to several hundred tons, depending on the specific design and configuration.
• Underhung Cranes: While they can also handle substantial loads, their capacity is generally lower compared to overhead cranes. They are suitable for applications that require moderate lifting capacities.

3. Versatility:

• Overhead Cranes: Due to their elevated configuration and ability to traverse large spans, overhead cranes offer greater versatility in terms of load movement and positioning. They can cover a larger working area and accommodate various lifting scenarios.
• Underhung Cranes: These cranes are often used in situations where the lifting requirements are more localized. They are suitable for smaller work areas and specific tasks that do not require extensive movement across a wide space.

4. Clearance Height:

• Overhead Cranes: They require sufficient vertical clearance above the crane runway to accommodate the bridge and hoist assembly.
• Underhung Cranes: These cranes have a lower profile and require less vertical clearance. They are ideal for spaces with limited headroom or low ceiling heights.

5. Cost and Installation:

• Overhead Cranes: The installation of overhead cranes involves erecting support structures and runways, which can be more complex and costly. However, they provide long-term benefits in terms of their load-handling capabilities and flexibility.
• Underhung Cranes: Installation of underhung cranes is typically simpler and more cost-effective since they do not require extensive support structures. They are a suitable option when cost and installation time are important considerations. Further in case of underhung cranes the long travel rail is avoided, as the crane moves on the lower flange of the long travel beam. This further reduces the cost.

6. Usage Applications:

• Overhead Cranes : the overhead cranes are more versatile and general in usage and application.
• Underhung cranes: there are special applications like a) when the building span is very high and we require cranes in a localized area only (b) underhing crane finds a typical example of load shifting from one bay to another

  The choice between an overhead crane and an underhung crane depends on factors such as load capacity, work area layout, available space, and specific lifting requirements.
