Description
Heavy-duty gantry cranes are primarily used for lifting Tunnel Boring Machines (TBMs) and are large-scale lifting equipment specifically designed for debris removal, equipment transportation, and shield support operations in subway tunnel construction. They can automatically perform debris removal, unloading, and cycle operations to meet the material transportation requirements of tunnel construction. In addition to debris removal and unloading functions, this crane can also perform critical tasks such as tunnel pipe plate lifting and shield machine assembly, making it an indispensable piece of equipment in shield construction.

Advantages
When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:
Ultra-Heavy Lifting Capacity
Designed for the heaviest TBM components, the crane offers lifting capacities from 50 up to 500 tons, with specialized models reaching 400–900 tons for large-diameter cutterheads and shield bodies .
Specialized Spreader & Multi-Angle Rotation
The upper spreader features 360° rotation to accommodate different cutterhead installation angles and excavation directions, while the adjustable clamps or hooks securely grip irregularly shaped heavy parts such as cutter plates and shield bodies .
Dual-Trolley Flexible Operation
The double-trolley design allows two trolleys to operate in linkage for lifting heavy cutterheads, or independently for handling tunnel segments, adapting to diverse construction needs and maximizing operational efficiency .
Intelligent Control & Deep Shaft Adaptability
Equipped with PLC frequency conversion speed regulation and anti-sway technology, the crane enables precise positioning in deep shafts with lifting heights up to 40+ meters. Dust-proof, moisture-resistant, and corrosion-resistant designs ensure reliabl
