Product Specifications

Technical details and manufacturing context for Thrust Ring/Reaction Structure

Definition
The Thrust Ring/Reaction Structure is a critical load-bearing component within the Main Jacking System, designed to absorb and distribute the substantial thrust forces generated during lifting operations. It serves as the interface between the hydraulic jacks and the structure being lifted, providing a stable reaction surface that prevents force concentration and ensures even load distribution across the system. This component is essential for maintaining structural integrity and operational safety during heavy lifting applications in construction, shipbuilding, and industrial maintenance.
Working Principle
The Thrust Ring/Reaction Structure operates by receiving compressive forces from hydraulic jacks and distributing these forces evenly across its surface area. During lifting operations, hydraulic pressure creates thrust that is transmitted through the ring/structure to the load. The component's geometry and material properties allow it to withstand high compressive stresses while minimizing deformation, ensuring that reaction forces are properly managed and transferred to the supporting structure without causing localized stress concentrations.
