30 Ton Rubber Tyred Gantry Crane Work in Tunnel Construction
Short Video Description
This video shows a 30 ton rubber tyred gantry crane used for tunnel construction at Singapore Changi Airport.
The gantry crane travels on rubber tyres instead of fixed rails, allowing it to move between different working positions on the construction site.
For tunnel construction, this type of mobile gantry crane can be useful when heavy materials and construction components need to be lifted and moved while the working area and lifting positions change during the project.

FAQ
Common questions about rubber tyred gantry cranes for tunnel construction.
1. Why use a rubber tyred gantry crane for tunnel construction?
Tunnel construction areas can change as the project progresses. A rubber tyred gantry crane can travel between different lifting positions without requiring a permanent crane rail system.
2. Can a 30 ton rubber tyred gantry crane work on a construction site?
Yes, provided the travelling surface is properly prepared and can support the crane's wheel loads. Ground bearing capacity, flatness and slope should be checked before operation.
3. What can the 30 ton crane be used for in tunnel construction?
Depending on the configuration, it can handle heavy construction components, steel structures, machinery, precast components, formwork and other project-specific loads.
Key questions to check before buying a 30 ton rubber tyred gantry crane.
4. What information is needed for a 30 ton tunnel gantry crane quotation?
Provide the capacity, span, lifting height, load dimensions, travelling distance, site layout, ground condition and working frequency .
5. Does the crane need fixed rails?
No fixed crane rails are required for the rubber tyred travelling system. However, the construction site still needs a suitable prepared travelling surface with adequate bearing capacity.
6. What should I check before buying a 30 ton tunnel construction gantry crane?
Check the rated capacity, span, lifting height, hoist type, rubber tyre system, wheel loads, ground bearing capacity, travelling route and available clearance . The crane should be designed around the actual construction site.
