Desafios e soluções

Traditional Challenges: Traditional core stacking and turning relied heavily on overhead cranes and manual labor, leading to inefficiency, poor synchronization, potential core deformation, high safety risks, and poor adaptability to various window sizes.
Process Optimization: The table allows for strap tying while the core is horizontal, eliminating the need for complex auxiliary clamps used in vertical tying, simplifying operations and reducing cycle time. The Synchronously Moving Beams on both sides adjust precisely to fit different core column diameters (MO), ensuring wide applicability

Reliability Design

Core Component Reliability: Critical hydraulic components (e.g., cylinders) use imported brands, guaranteeing long-term operational stability and high reliability from the source, thereby reducing failure rates.
Structural Strength & Precision: Finite Element Analysis (FEA) is used in design optimization, ensuring sufficient strength and stiffness under load (1-100 tons). High-precision metrics, such as table deformation <2mm and perpendicularity error <2mm before and after turning, provide a solid foundation for core stacking quality. The design of turning support legs offers additional safety protection after 90-degree rotation
