Primary Function: To safely lift and move precast concrete slabs, stone slabs, steel plates, or other flat, heavy materials.
Need: Used when the slab lacks built-in lifting eyes, holes, or handles for conventional rigging.
Mechanism: Typically utilizes a self-locking or friction-grip clamp
The grip automatically tightens on the edge of the slab proportional to the weight being lifted.
This design ensures a secure hold, preventing slippage when under tension.
Safety Criticality: Provides a secure and stable attachment point, which is crucial for safety during material handling on construction sites.
Types: Available in various designs, including:
Vertical Slab Hangers: For lifting and moving slabs in an upright or vertical position.
Horizontal Slab Grabs: For transporting slabs while they remain flat.
Construction: Generally made from high-strength steel to handle heavy loads, often featuring protective polyurethane or rubber pads to prevent damage to the slab’s surface.
Usage: They are attached to lifting equipment (cranes, hoists, forklifts with boom attachments) via a shackle or sling.
