PDB Type Horizontal Lifting Clamps: Precision Grip for Steel Plate Handling
The Horizontal Lifting Clamps (PDB Series) are specialized rigging tools engineered for the safe transport of steel plates and structured steel sections. Unlike vertical lifters, these clamps are designed to work in pairs or groups to maintain a perfectly level horizontal plane during movement. As a trusted lifting equipment supplier , CloudHub provides PDB clamps manufactured from high-grade alloy steel, ensuring maximum structural integrity for heavy industrial applications.
Advanced Bite Technology and Safety Protocols
Safety in plate handling is determined by the relationship between mechanical pressure and the Coefficient of friction . Our PDB clamps are designed with this precision in mind:
High-Friction Tooth Surface: The “bite” or tooth surface is induction-hardened to ensure a secure grip without damaging the structural properties of the steel.
Load Balance Engineering: Effective use of Horizontal Lifting Clamps requires a vertical lift balance. The tension must be distributed equally across the pair of clamps to prevent asymmetrical stress on the lifting points.
Thermal Resilience: These clamps are operational within a wide temperature range from -20°C to 150°C, making them suitable for both cold-weather construction and hot-rolling mill environments.
Maintenance Integrity: To ensure long-term performance, moving parts should be periodically lubricated. However, it is critical that lubricants never contact the Mechanical advantage zones, such as the tooth surface or mat slice.
Operational Guidelines for Professional Riggers
Using Horizontal Lifting Clamps requires strict adherence to safety standards to prevent catastrophic failure:
Material Specificity: These clamps are strictly designed for steel. They should not be used on materials with excessively high hardness or irregular shapes that might compromise the grip.
Surface Preparation: Before engaging the Horizontal Lifting Clamps, the steel surface must be cleared of rust, oil, or foreign bodies that could reduce the effective bite of the jaws.
Operational Stability: Avoid sharp movements or sudden stops. Impact loading can create transient forces that exceed the working load limit (WLL), leading to potential slippage.
Inspection Protocol: Routine checks for distortion, breakdown, or excessive wear are mandatory. We recommend using only original accessories to maintain the certified safety rating of the equipment.
