100t Metro Muck Handling Gantry Crane for Urban Rail Construction
Featured project image of the 100t-class gantry crane installed above the Guangfo Ring Line construction area.
Metro and tunnel construction sites need cranes that can lift muck containers, construction materials and equipment from deep excavation zones while working above shafts, temporary structures and active civil works. Capacity, below-rail lifting depth, hook approach and safety protection are central procurement parameters.
Henan Mine Crane supplied two 100t double-main-girder gantry cranes for the Guangfo Ring Line project in the Guangdong-Hong Kong-Macao Greater Bay Area. The source states that the cranes are used for lifting tunnel muck and materials during metro construction and that the below-rail lifting attachment can reach a depth of 40 m.
Project Background
Deep metro construction requires repeated vertical lifting from shafts or excavation zones. The crane must provide sufficient rope capacity and lifting depth while maintaining safe travel above the construction opening.
The source states that the gantry structure was developed through computer-aided design and analysis. Travel and hoisting functions include safety-protection devices to improve operating safety and reliability.
Customer Challenges
- Lifting heavy muck containers and construction materials from deep excavation zones.
- Providing up to 40 m below-rail lifting depth without losing control of the load.
- Operating safely above shafts, temporary supports and active construction areas.
- Managing high-frequency lifting cycles during metro excavation.
- Maintaining structural stability and reliable braking under changing construction loads.
- Coordinating the crane with civil construction progress and restricted site access.
Henan Mine Crane Solution
The referenced solution uses two 100t double-main-girder gantry cranes customized for metro muck removal and material lifting. The below-rail lifting system is configured for depths up to 40 m.
Computer-aided structural design and analysis support the gantry configuration, while safety-protection devices are incorporated into critical travel and hoisting motions.
For a new tunnel project, Henan Mine Crane can size the rope system, drum capacity, lifting depth, span, runway arrangement and below-the-hook attachment from the shaft geometry and muck-container specification.

- Safety functions can be matched to shaft openings, travel limits and construction operating rules.
- Delivery and installation can be coordinated with metro civil works and project milestones.
Frequently Asked Questions
How is lifting depth specified for a metro muck gantry crane?
Provide the rail elevation, lowest pickup point, required hook or attachment approach, container height and any additional rope travel needed for rigging and safe clearance.
What was the lifting depth of the referenced metro project crane?
The source states that the below-rail lifting attachment can reach 40 m.
What should be included in the RFQ?
Provide rated load, muck-container dimensions, shaft size, span, runway length, below-rail lifting depth, cycle frequency, travel speeds, power supply and site safety requirements.
