A gantry crane for shield tunneling is a specialized lifting device specifically designed for tunnel engineering, particularly in subway shield construction. Its main task is to safely lift and transfer large shield machine components, tunnel segments, excavated muck, and other construction materials at the worksite.
The gantry crane for shield tunneling is a specialized lifting device specifically used in tunnel engineering, particularly for subway shield construction. Its main task is to be responsible for the safe lifting and transfer of large shield machine components, segments, muck, and other construction materials on the construction site.
The gantry crane for shield tunneling is mainly used for the installation of the cutterhead and shield body of the trenchless shield machine, as well as the lifting of tunnel support segments during construction.
It adopts a special spreader that can rotate 360°, suitable for installing the cutterhead at different angles.
It adopts a double-trolley structure. The two trolleys can be linked for lifting the cutterhead or operate independently for lifting segments.
The hoisting mechanism uses open gear drive, saving costs.
This type of crane needs to meet the following core requirements:
High safety requirements: The lifted objects are of high value, and the operating space is relatively fixed and narrow.
Complex working conditions: Adapts to the多变 environment of construction sites, often requiring outdoor or semi-outdoor operation.
High efficiency requirements: Needs to efficiently coordinate with the continuous operation process of shield construction.
As a leading crane manufacturer in China, Weihua possesses manufacturing qualifications for over 200 types in 10 major series and is capable of providing highly customized gantry crane solutions based on the special working conditions of shield construction.
Features & Advantages
Customized Safety Design
Targeting the high-risk environment of shield construction, safety concepts are integrated from structural design to the control system. Key mechanisms (such as the hoisting mechanism) are designed with extra-long life and large safety margins to cope with extreme 24/7 operating conditions.
Intelligent Monitoring System
Can be equipped with a crane full lifecycle safety management monitoring system for real-time equipment status monitoring and early warning.
Precise Anti-Sway & Positioning
Weihua’s independently developed electrical anti-sway control technology is internationally领先, ensuring that when lifting precision and expensive shield components, operations are fast, accurate, and stable, achieving millimeter-level precise positioning.
Smooth & Efficient Operation
Each mechanism uses variable frequency speed regulation and PLC control, resulting in smooth start/stop and low impact, effectively protecting the lifted load and the equipment itself.
Sturdy Structure
The crane travel mechanism adopts a special design to ensure that even on potentially uneven tracks at the construction site, all wheels maintain uniform force and stable operation.
High Reliability Design
The high-reliability design of core components ensures long-term stable operation of the equipment in relatively harsh construction environments with dust and moisture.
