Gantry Cranes, Semi-Gantry Cranes
Gantry and semi-gantry cranes offer an ideal solution for efficient, fast, and safe outdoor material handling in industrial, logistics, or construction environments. These crane systems are completely independent of the building structure, as they operate on ground-level rail tracks, allowing for flexible installation on any worksite, adapted to the structural characteristics of the location.
The gantry cranes offered by GD are extremely versatile in design, with the following configurations available:
- Single-sided or double-sided cantilevered designs, depending on the loading area requirements.
- Non-cantilevered versions, for maximum stability and structural simplicity.
A special version is the semi-gantry crane, where one side runs on a rail mounted to a building or elevated structure, while the other side operates on a ground-level rail track. This configuration is ideal for narrow spaces or locations with varying height conditions.
From a structural perspective, GD gantry cranes are available in nearly any configuration:
- Single-girder or double-girder designs, depending on the required load capacity and span.
- Hook-operated models for general lifting tasks.
- Grab bucket cranes, ideal for handling bulk materials such as gravel, sand, or waste.
- Custom gripping systems for the safe handling of unique, oversized, or delicate loads.
GD’s gantry cranes cover a wide load capacity range, from 1 ton up to 160 tons, offering a solution for light-duty applications as well as extremely heavy industrial lifting tasks.
The crane control options are fully customizable to meet the customer’s operational preferences:
- Operator cabins or onboard control stations, providing direct oversight.
- Pendant control, a simple and cost-effective solution for smaller systems.
- Radio remote control, offering maximum freedom, safety, and efficiency, especially in hazardous or hard-to-reach work areas.
If needed, gantry and semi-gantry cranes can also be designed for indoor use, depending on the building layout.
A GD specialty is a semi-gantry crane design where the side moving on the floor level does not require a dedicated rail track; it can safely travel on a flat surface with adequate load-bearing capacity. This design is recommended for load capacities up to 10 tons.
All GD gantry and semi-gantry cranes stand out for their robust construction, reliability, and long service life. They are fully customizable to suit your operational needs – from load capacity and span to control method and installation environment.

Frequently Asked Questions
What is the difference between a gantry crane and a semi-gantry crane?
A gantry crane runs on ground-level rails on both sides and is completely independent of any building. A semi-gantry crane runs on a ground-level rail on one side and a rail mounted to a building or elevated structure on the other.
Where are gantry and semi-gantry cranes typically used?
They are ideal for outdoor applications in industrial sites, logistics yards, and construction zones, but can also be adapted for indoor use if required.
What lifting capacities are available?
GD offers gantry cranes with load capacities ranging from 1 to 160 tons, covering both light and heavy-duty lifting needs.
Are single-girder and double-girder versions available?
Yes. Single-girder designs are typically used for lighter loads, while double-girder systems offer higher load capacity and stability for heavy-duty applications.
Can the cranes be equipped with special attachments?
Yes. Options include grab buckets for bulk materials, hook-operated models for general lifting, and custom gripping systems for oversized or sensitive items.
What control options are available?
Customers can choose between:
- Onboard operator cabins
- Pendant (wired) controls
- Radio remote controls for enhanced safety and flexibility
Do these cranes require dedicated rail tracks?
Standard gantry cranes require rail tracks. However, GD offers a unique semi-gantry design that can run on flat, load-bearing floors without a dedicated track—ideal for loads up to 10 tons.
