Purpose and key benefits Vertical scissor gripper that increases grip strength as tension rises, providing a progressively tighter, more secure hold during lifting. Polyurethane rubber chuck delivers nonslip contact, heat insulation, and resistance to shock and abrasion to protect finished surfaces and reduce slippage. Fixture tool with adjustable openings adapts to different stone sizes and shapes, reducing the need for multiple tools and speeding setup. Heavyduty alloy steel lifting clamps engineered for professional use, offering reliable strength and longterm durability under repeated, rigorous handling. How this product solves common problems Prevents slipping and surface damage: the polyurethane rubber chuck cushions contact and provides a firm, nonmarring grip. Adapts to varying loads: the adjustable fixture accommodates a range of stone sizes so one tool can serve multiple tasks. Increases safety under load: the scissor gripper design tightens with tension, maintaining grip as lifting forces change. Reduces downtime and replacements: alloy steel construction and abrasionresistant components extend service life in demanding environments. Key features and specifications Vertical scissor gripper action: grip strength increases as tension increases for secure handling. Wide jaw opening: supports a variety of material thicknesses and geometries for broad compatibility with machinery and onsite equipment. Polyurethane rubber chuck: nonslip, heatinsulating, shockabsorbing, and abrasionresistant contact surface to protect material finishes. Adjustable fixture openings: simple adjustment to fit different stone sizes and profiles without specialized parts. Heavyduty alloy steel clamps: designed to withstand professional stonehandling loads and frequent use. Performance and compatibility Function: secure lifting, positioning, and transfer of stone slabs and similar materials with reduced risk of surface damage. Compatibility: fits standard lifting machinery and can be used with cranes, hoists, and material handling equipment that accept vertical scissorstyle clamps. Material and durability: polyurethane chuck for protective contact; alloy steel body for structural strength and longevity. Maintenance: routine inspection of rubber chuck and clamp fastenings recommended to ensure continued performance. Typical use scenarios 1. Countertop fabrication and installation: safely lift and position granite, marble, or engineered stone slabs without chipping or surface marking. 2. Stone yard loading and unloading: load slabs onto trucks and stack in storage racks using adjustable openings to match varying slab sizes. 3. Construction site erection: move cut stone pieces into place for cladding or masonry work where a secure, nonmarring grip and durable clamps are required. Safety and operator notes Always verify compatibility with your lifting equipment and rated load limits before use. Inspect the polyurethane chuck and alloy steel components for wear or damage prior to each shift. Ensure adjustments are locked securely and that the scissor gripper engages properly under load. Designed to provide adaptable, protective, and robust lifting performance for stone handling and similar applications, this system combines the vertical scissor gripper, polyurethane rubber chuck, adjustable fixture, and heavyduty alloy steel clamps to improve safety, reduce material damage, and simplify handling across multiple job types.
