Why must PDB horizontal plate clamps always be used in pairs?

Horizontal plate clamps rely on opposing tension and balanced leverage to grip steel sheets horizontally. Using a single clamp causes the plate to tilt, reducing friction and resulting in severe slipping hazards. Always use at least two clamps with a two-leg chain sling or spreader beam.

What is the maximum allowed sling angle for PDB horizontal clamps?

The included angle between the chain legs should not exceed 60 degrees. Angles greater than 60 degrees significantly reduce the effective Working Load Limit (WLL) and place excessive lateral strain on the clamp eyes.

PDB Horizontal Plate Lifting Clamps (0.8T-12T) | Tie Shou - Подъемное оборудование Tieshou

Tie Shou PDB Series Horizontal Plate Lifting Clamps are specially engineered for the stable horizontal hoisting, transfer, and stacking of single steel plates, sagging steel sheets, and bundled metal plates. Manufactured from drop-forged high-tensile alloy steel and fully compliant with EN 13155 and ASME B30.20 safety standards, the PDB series offers a Working Load Limit (WLL) range from 0.8 Ton to 12 Tons per pair.

Designed with a self-tightening cam jaw mechanism, PDB clamps utilize load tension to increase clamping force on the plate surface. Safety Note: Horizontal plate clamps must always be used in pairs or quad configurations with a spreader bar or two-leg chain sling to ensure balanced load distribution and prevent slippage.

Key Engineering Features & Advantages:

High-Grade Alloy Steel Forging: Compact, lightweight body forged from low-carbon alloy steel for high impact resistance under extreme heavy-duty shipyard environments.
Induction-Hardened Gripping Cam: Special heat-treated teeth design provides positive traction on smooth, oiled, or mill-scale steel plates.
Wide Jaw Capacity: Adjustable jaw openings accommodating plate thicknesses from 0 mm up to 150 mm.
Safety Proof Load Certified: 100% factory proof-tested at 200% of rated capacity with individual RFID/serial number traceability.
