Key benefits and why you need this stone lifting solution Safer, faster lifting: the vertical scissor gripper converts downward tension into a tighter hold, reducing slippage and lowering the risk of dropped loads during handling. Damage prevention: the polyurethane rubber chuck protects finished stone surfaces from scratches and chips while providing heat insulation and shock absorption. Versatile and precise: adjustable jaw opening and chain length let you handle a wide range of stone sizes and shapes with a single tool, cutting setup time and the number of specialized clamps required. Built for heavy work: heavyduty alloy steel construction and a selflocking nut deliver the durability and stability required on busy job sites. Core functions and standout features Vertical scissor gripper design: increases grip strength automatically as lifting tension increases, delivering a secure hold without complex controls. Wide jaw opening: accommodates larger blocks and slabs, expanding compatibility with excavators, cranes, forklifts, and other lifting machinery. Polyurethane rubber chuck: nonslip surface engineered to prevent stone damage, provide heat insulation, and absorb shock during loading and transport. Adjustable fixture tool: variable jaw opening and adjustable chain length for precise positioning and secure gripping of different stone dimensions. Heavyduty alloy steel body: resists deformation and wear under rigorous use; integrated selflocking nut maintains clamp position and improves operator safety. Compatibility and performance Function: designed for vertical lifting and transferring of stone blocks, slabs, and similar materials. Equipment compatibility: suitable for use with excavators, cranes, hoists, and general lifting machinery that accept standard lifting attachments. Material and durability: polyurethane chuck for surface protection; alloy steel clamp body for structural strength and long service life. Performance advantage: automatic tensionincreased grip reduces the need for constant operator adjustment and improves throughput on repetitive lifting tasks. Typical applications and scenarios Quarry to truck loading: quickly secure irregular stone blocks for safe lifting from the quarry face into hauling equipment without surface damage. Stone yard and fabrication shops: move cut slabs and finished pieces between storage racks, saws, and polishing stations while preserving edge and face quality. Construction and landscaping installations: lift and place heavy pavers, retainingwall blocks, and architectural stone using excavators or cranes with minimal handling risk. Practical user considerations Adjustability: change jaw opening and chain length onsite to match stone dimensions and lifting angle. Safety: the selflocking nut reduces the chance of accidental loosening during repeated cycles. Surface care: polyurethane chuck provides nonslip contact while protecting finished surfaces from impact and abrasion. Maintenance: durable alloy steel construction simplifies inspection and longterm use; check the rubber chuck and locking mechanism periodically for wear. What makes this product stand out Combines a selftightening vertical scissor mechanism with a protective polyurethane chuck for both secure lifting and stone surface protection. Built for integration with common lifting machinery and adaptable to a wide range of stone sizes through adjustable fixtures and chains. Robust alloy steel construction with a selflocking nut for consistent, reliable performance in demanding environments.
