Introduction
Double Girder Gantry Crane With Shield is a professional heavy-duty gantry crane specially developed for tunnel and shield engineering construction. Adopting optimized double girder rigid structure and dual-trolley design, the crane is equipped with a 360° rotatable dedicated spreader to adapt to multi-angle hoisting and installation operations. It adopts open gear lifting drive structure for stable and cost-effective operation. Supported by PLC frequency conversion control system, the whole machine features flexible operation, accurate motion control and stable mechanical performance. All design, manufacturing and inspection procedures comply with the latest national industry standards. With complete safety protection configurations, it serves as the core special lifting equipment for shield machine assembly and tunnel construction projects.
Application Scenario
This professional shield engineering gantry crane is specially applied in underground tunnel construction and trenchless shield engineering projects. It is mainly used for integral hoisting, positioning and installation of shield machine components, including shield body and large cutterhead. It also undertakes frequent lifting and handling of tunnel support segments and pipe sheets during construction. It perfectly adapts to complex construction site conditions and multi-angle installation requirements, meeting high-precision and high-safety hoisting demands of municipal tunnel and underground engineering construction.
Advantages
Double Girder Gantry Crane With Shield owns outstanding advantages of flexible operation, high precision, high safety and low comprehensive cost. The 360° rotatable spreader adapts to multi-directional and multi-angle installation of shield cutterheads, greatly improving construction flexibility. The dual-trolley structure supports both linkage synchronous hoisting for large integral components and independent separate operation for tunnel segments, realizing dual-purpose efficiency. The open gear drive lifting structure simplifies mechanical configuration and effectively reduces equipment investment and maintenance costs. Equipped with complete overload protection and standardized safety interlock devices, it maximizes the safety of operators and construction equipment. The PLC frequency conversion control system ensures stable running and precise institutional control. Featuring reliable performance and easy daily maintenance, it provides efficient and safe professional lifting solutions for tunnel shield engineering.
