Semi Gantry Crane vs. Full Gantry Crane: Top 5 Differences
Choosing the right lifting equipment can significantly optimize your workplace efficiency. While both full and semi-gantry cranes are powerful tools, their structural designs serve different operational needs.Want to learn about single vs. double girder designs? Check our previous Gantry Crane Guide.
1. Structural Design and Support
The primary difference lies in the support structure. A full gantry crane is a type of overhead crane with two freestanding legs that move along a track. A semi-gantry crane, however, is designed with one side supported by legs while the other side rests on a wall or building structure.
2. Space Utilization
Semi-gantry cranes are ideal for narrow workshops. Because they use the building structure as one support, they significantly reduce floor space usage compared to full gantries. They help preserve headroom and floor space under the fixed side.
3. Cost-Effectiveness
If you are working with a tight budget, the semi-gantry model is often more attractive. It offers lower initial investment and maintenance costs because it requires fewer legs and shorter rails.
4. Installation and Layout Flexibility
Semi-gantry cranes offer greater flexibility for changing site layouts. They are often easier to install or relocate due to their modular design. Full gantry cranes, while providing maximum lifting capacity and operational freedom, require a more permanent and spacious setup.
5. Application Scenarios
Full Gantry: Best for open yards, shipyards, and heavy-duty lifting.
Semi-Gantry: Perfect for indoor work cells, especially when installed under existing overhead cranes.

Frequently Asked Questions
1. Is a semi-gantry crane safer than a full gantry?
Both are equally safe when manufactured by Nybon Crane. Safety depends on proper installation and choosing the right duty class for your operations.
2. Can a semi-gantry crane be installed outdoors?
Yes, but they are most effective indoors where they can utilize the existing building structure for support.
3. Does the semi-gantry save a lot of space?
Yes! By mounting one side to the wall, you eliminate a ground track and leg, freeing up over 1 meter of floor space in narrow aisles.
4. Why choose a full gantry for heavy loads?
Full gantry cranes offer maximum lifting capacity and stability for extreme heavy-duty lifting in open areas.
5. Can I use a semi-gantry under an overhead crane?
Absolutely. Semi-gantries are frequently installed under larger overhead cranes to handle localized lifting tasks in a specific work area.
