How Does a Rubber Tyred A-Frame Goliath Crane Work on Soil Ground
Short Video Description
This video shows a rubber tyred single girder A-frame goliath gantry crane handling materials on the ground without fixed rails.
The crane travels on rubber tyres and can move between different working areas, making it suitable for outdoor yards, factories, construction sites, workshops and other ground-level material handling applications.
The A-frame structure provides a simple support system, while the rubber tyres give the crane more flexibility than a rail-mounted gantry crane.

Where Can a Rubber Tyred Gantry Crane Be Used?
One of the main advantages of a rubber tyred design is that the crane does not depend on a fixed runway across the whole working area.
It can be considered for:
- Factory yards
- Steel fabrication yards
- Construction sites
- Precast concrete yards
- Machine and equipment yards
- Outdoor maintenance areas
- Material storage yards
- Temporary lifting areas
The important point is that rubber tyres do not mean the crane can run on any ground. The travelling surface still needs enough strength, levelness and stability for the actual crane and load.
Can It Run on Different Ground Conditions?
Yes, but the ground condition must be checked before selecting the crane.
Typical working surfaces may include:
- Concrete yards
- Asphalt surfaces
- Compacted industrial ground
- Construction site working areas
- Prepared outdoor material yards
For uneven, soft or unprepared ground, additional engineering may be required. The key factors include ground bearing capacity, surface flatness, slope, drainage and travelling conditions.
Rubber tyres give the crane mobility. They do not cancel the laws of physics. The ground still gets the bill.
Why Choose Rubber Tyres Instead of Fixed Rails?
A rail-mounted gantry crane follows a fixed travelling path. A rubber tyred gantry crane can move within its designed working area without installing long permanent rails.
| Rubber Tyred Gantry | Fixed Rail Gantry |
|---|---|
| Flexible travelling position | Fixed travelling route |
| No long crane rails required | Requires rail installation |
| Suitable for temporary or changing work areas | Best for permanent working areas |
| Can work in different ground-level areas | Works along the designed runway |
FAQ — Want to Know
Common questions about rubber tyred A-frame goliath gantry cranes.
1. Can a rubber tyred goliath crane work without fixed rails?
Yes. The crane travels on rubber tyres instead of fixed crane rails. However, the ground must have enough strength, flatness and stability for the crane and load.
2. What types of ground can a rubber tyred gantry crane work on?
It can be designed for concrete, asphalt, compacted industrial ground and other prepared surfaces. The actual ground bearing capacity and travelling condition should be checked first.
3. What is the advantage of an A-frame rubber tyred gantry crane?
It combines the lifting capacity of a gantry crane with the mobility of a rubber-tyred travelling system. This is useful when materials need to be handled in different ground-level working areas.
FAQ — Want to Buy
Key questions to check before buying a rubber tyred gantry crane.
4. What information is needed for a rubber tyred gantry crane quotation?
Provide the lifting capacity, span, lifting height, load dimensions, travelling distance, ground condition and working area layout .
5. Can the 1–20 ton rubber tyred gantry crane be customized?
Yes. The capacity, span, lifting height, travelling system, hoist type, control method and overall dimensions can be designed according to the application and site conditions.
6. What should I check before using the crane on outdoor ground?
Check the ground bearing capacity, surface flatness, slope, travelling path, turning space, drainage and weather conditions . The rubber-tyred crane should be designed for the actual working surface.
