Semi Gantry Cranes
The semi gantry crane is one of the most widely used and cost-effective lifting solutions for light to medium-duty material handling applications.
This type of crane features a single main girder supported by one leg running on a ground-mounted rail and the other side supported by a building structure or a wall-mounted rail. The electric hoist travels along the girder, enabling smooth horizontal movement, while the crane itself moves longitudinally along the working area, providing efficient three-dimensional material handling.
Semi gantry cranes are designed with a compact structure, offering excellent performance with lower weight and reduced cost compared to full gantry systems.
As a professional semi gantry crane manufacturer, supplier, and exporter in China, MecBase offers high-quality and fully customizable solutions for global customers.

Why Choose a Single Girder Gantry Crane?
- Space-saving – Uses existing building structure on one side, reducing floor space occupation
- Cost-effective – Lower material and installation cost compared to full gantry or overhead cranes
- Versatile – Suitable for workshops, production lines, outdoor yards, and industrial plants
- Easy installation – Minimal structural modification required, quick setup
- Customizable – Capacity 2t–40t, span 15–30m, multiple control options available
- Reliable – Operates in harsh environments (-25℃ to +40℃) with work duty A3–A6
- Safe & efficient – Smooth three-dimensional material handling with precise load control
Applications
Semi gantry cranes are widely used in:
- Workshops & manufacturing plants – utilizing existing building structures for support
- Warehouses & logistics centers – along loading docks and wall sides
- Construction sites – for material handling along building perimeters
- Steel & fabrication yards – where one side can be supported by structures
- Outdoor storage areas – ideal for operations along facility walls
👉 Especially suitable for light to medium-duty operations in spaces where full gantry cranes are not feasible.
Structure & Components
A semi gantry crane mainly consists of:
- Main Girder: Load-bearing beam supporting the hoist
- Gantry Leg: One leg running on ground rail; the other side supported by building structure or wall rail
- Electric Hoist: Lifting mechanism (wire rope or chain)
- Traveling System: Enables crane movement along ground and wall rails
- Electrical & Control System: Ensures safe and precise operation
👉 These components enable efficient three-dimensional material handling with optimized space utilization.
What is the difference between a full gantry crane and a semi gantry crane?
| Feature | Full Gantry Crane | Semi Gantry Crane |
| Support | Two legs on ground rails | One leg on ground rail, one side supported by building |
| Space required | Larger floor space | Compact, utilizes existing structure |
| Installation | Requires two sets of rails | Only one set of ground rails needed |
| Cost | Higher | More cost-effective |

FAQs About Semi Gantry Cranes
A semi gantry crane is a type of lifting equipment that features one leg running on a ground-mounted rail, while the other side is supported by a building structure, wall-mounted rail, or existing column. This design offers a space-saving alternative to full gantry cranes.
Yes. Semi gantry cranes are designed to operate in temperatures ranging from -25℃ to +40℃ with relative humidity ≤85%. Outdoor models can be equipped with weather-resistant components and appropriate rail systems.
Semi gantry cranes are available with work duty ratings from A3 to A6, covering light to heavy-duty applications. The appropriate duty class depends on the frequency of use and load conditions.
Installation requires a supporting building structure or wall rail on one side, and a ground rail on the other. Compared to full gantry systems, installation is faster and requires less structural modification.
- Consider the following factors:
- Load capacity – maximum weight to be lifted
- Span – distance between support points
- Lifting height – required vertical reach
- Work duty – frequency and intensity of use
- Control mode – operator preference and safety needs
- Environment – indoor or outdoor, temperature, humidity
