Crab Type Support Tower

Crab Type Support Tower - Heavy-Duty Modular Shoring System for Large-Span Construction

Shandong Xingrui Building Materials Co., Ltd. manufactures the Crab Type Support Tower, a high-performance modular shoring system engineered from Q235 premium steel for large-span floor slabs, bridges, and elevated heavy-load support. With a single tower load-bearing capacity reaching up to 500kN, this crab-style structured load-bearing tower frame ensures exceptional overall stability across demanding construction environments. Our world leading facility spans 79,800 sqm, with over 40,000 sqm of standardised workshops, supported by 12 welding robots and 6 automatic welding lines. Backed by ISO 9001, ISO 14001 and ISO 45001 certifications, we provide you solutions you can depend on. Our solutions are simple to assemble, reusable and precisely developed for your most essential infrastructure projects.

What Makes Our Crab Type Support Tower Superior?

Our product is modular, turning temporary shoring into a durable and predictable load bearing system. No more guessing in installation, since you will get standardised components that guarantee even load distribution. Unlike typical tube-and-clamp scaffolding,

The crab-style arrangement offers multidirectional stability, achieved by its built-in framework of horizontal and diagonal bracing. Your construction crew can build rectangular load-bearing towers rapidly, without loose connections, cutting labour costs and increasing job site safety.

This system is designed for numerous uses on different projects and can easily be adjusted in size and height to suit your individual project needs. Whether you are working on bridge cap beams or industrial plant floor slabs the tower's modular construction adapts effortlessly to difficult geometries and limited access places.

Technical Specifications

Core Applications for Maximum Efficiency

Bridge Construction Support

Your bridge projects demand reliable shoring for box girder casting operations. The Crab Type Support Tower provides high-altitude stability and exceptional wind resistance, making it ideal for temporary support of bridge cap beams where safety cannot be compromised.

Industrial Infrastructure Projects

When constructing heavy-duty floor slabs, silos, or facilities with concentrated loads exceeding standard scaffolding limits, you need equipment that delivers. Our system handles extreme loading conditions while maintaining structural integrity throughout the concrete curing process.

Hydroelectric and Underground Works

For tunnel lining, dam gallery forms, and confined spaces where traditional cranes face access challenges, this modular tower excels. Its compact footprint and rapid assembly capabilities allow your team to work efficiently in high-humidity underground environments without sacrificing load-bearing performance.

Why Choose Xingrui's Manufacturing Excellence?

Our production facility in Rizhao City combines advanced automation with rigorous quality control. With 920 employees including 180 professional technicians, we maintain strict oversight throughout the manufacturing process.

Every component undergoes spectroscopic analysis to verify material composition. Our 12 welding robots ensure precision connections, followed by ultrasonic testing to detect any structural imperfections before products leave our facility.

We've successfully exported to over 100 countries and regions across Asia, Europe, Americas, Oceania, and Africa. This extensive global experience means you receive products proven in diverse climatic conditions and construction standards.

Our integrated logistics network through Rizhao's international seaport, airport, and high-speed rail hub ensures timely delivery for your project schedules, whether you need standard configurations or custom solutions based on your drawings.

Quality Assurance You Can Trust

Material integrity forms the foundation of our quality system. We perform comprehensive spectroscopic analysis on raw steel to confirm chemical composition aligns with grade requirements before production begins.

Welding precision receives special attention through automatic robotic welding complemented by magnetic particle inspection. This dual approach eliminates internal cracks and ensures consistent weld quality across all connection points.

Load testing includes both destructive and non-destructive compression tests. We verify ultimate load capacity against theoretical calculations, giving you confidence that the Crab Type Support Tower will perform exactly as specified under real-world conditions.

Dimensional tolerance checks focus on verticality and concentricity of node connections. These rigorous inspections prevent eccentric loading during site assembly, ensuring your tower maintains structural stability throughout its service life.

FAQ

Q：How does the system compare to traditional Ringlock scaffolding?

A：While both systems are modular, the product is specifically optimized for vertical shoring and heavy-duty load paths. You get higher density bracing options and superior load distribution for bridge shoring applications.

Q：What maximum height can be achieved?

A：Following a height-to-width ratio of 3:1 or 4:1, standard configurations remain stable. With specialized outriggers and wall ties, heights exceeding 40 meters are achievable when verified by structural engineering audits.

Q：Is the system compatible with standard beams?

A：Yes, the U-head jack accommodates H20 timber beams, aluminum beams, and steel primary joists. This compatibility gives you flexibility in selecting deck systems based on your project specifications.

Q：What maintenance does the system require?

A：After project completion, inspect vertical members for deformation, check weld points for fatigue, and clean screw threads on base and U-head jacks. Proper maintenance ensures continued adjustability and extends service life across multiple deployments.

Q：Can the tower handle seismic zone requirements?

A：The rigid node connections and diagonal bracing provide superior energy dissipation compared to traditional systems. Seismic performance typically exceeds EN 12811-1 vibration test standards, making it suitable for earthquake-prone regions.
