Shield Gantry Crane is a professional heavy-duty lifting equipment specially designed for shield machine handling and tunnel construction. It adopts a heavy-duty gantry frame structure, made of high-strength steel through integral welding and precision processing, ensuring excellent structural rigidity and super strong load-bearing capacity. It is equipped with a high-performance hoisting mechanism, stable traveling system and precise positioning device, integrating lifting, moving, positioning and auxiliary installation functions. The equipment is optimized for shield machine-related handling scenarios, capable of stably lifting and transferring shield machine components, segments and construction materials, ensuring safe and efficient construction, and providing reliable support for tunnel shield construction projects.

Shield Gantry Crane is mainly applied to shield tunnel construction projects, covering urban subway construction, cross-river tunnel construction, highway tunnel construction and other shield construction sites. In shield construction sites, it is used to hoist and transfer shield machine main bodies, cutter heads, segments and construction auxiliary materials, realizing the assembly and disassembly of shield machines in the tunnel portal. It undertakes the transfer of shield segments from storage yards to tunnel entrance, matching the shield tunneling rhythm and ensuring the continuity of segment installation. It is also applicable to the handling of large-scale equipment and materials in tunnel construction auxiliary sites, adapting to outdoor and semi-outdoor heavy-load operation scenarios with complex terrain.

Shield Gantry Crane takes heavy load-bearing, high stability and strong adaptability as the core, with obvious advantages in shield construction handling. It adopts a heavy-duty gantry structure with reasonable stress distribution, strong overall stability and excellent wind resistance, capable of stably bearing the weight of large shield machine components and segments, avoiding deformation or damage during handling. The high-precision positioning device and anti-sway control technology ensure accurate alignment of shield components and segments with installation positions, improving construction efficiency and quality. It is made of high-strength steel and undergoes strict anti-corrosion and anti-wear treatment, which can adapt to harsh construction environments such as dust, humidity and alternating temperature, extending the service life of the equipment. The modular design facilitates disassembly, transportation and on-site assembly, adapting to the frequent transfer needs of shield construction sites. It is equipped with perfect safety protection devices, including overload protection, anti-collision protection and emergency braking, ensuring the safety of construction personnel and equipment. The operation is simple and efficient, with stable performance and low failure rate, reducing later maintenance costs and ensuring the smooth progress of shield construction.
