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:
Double trolley design
Adopting a double trolley design, the two trolleys can be linked to lift the cutter disk and can also work alone to lift the tube sheet, adapting to a variety of construction needs.
Flexible construction
The spreader and extender can be rotated 360° to meet the needs of the multi-angle installation of the cutter and pipe sheet. The trolley lifting mechanism can be rotated 180° to adapt to different slag discharge directions, enhancing construction flexibility.
Intelligent operation
Equipped with a PLC program control system, it supports intelligent operation and precise control, realizing automated slag discharge, slag dumping, and cyclic operation, which significantly improves construction efficiency.
Safety protection
Equipped with perfect safety indication and overload protection device to ensure the safety of operation. The lifting mechanism adopts an open gear drive, a simple and reliable structure, and easy maintenance.<
