Terrier 1.5 TNMK Non-Marring Lifting Clamp - #862037

Terrier TNMK Non-Marking Vertical Lifting Clamps – Precision Lifting for Delicate Surfaces

The Terrier TNMK Series lifting clamps are expertly engineered for vertical lifting, transporting, and turning of plates or materials that must remain scratch-free and unmarred. Ideal for use with stainless steel, aluminum, glass, painted metal, composite, and wood, these clamps use synthetic jaw pads to grip without damaging the surface. Designed with both safety and efficiency in mind, all models feature locking mechanisms, safety latches, and durable steel construction.

Key Features

• Non-Marking Clamping: Equipped with dual synthetic anti-friction pads to prevent marking, scratching, or surface damage.
• Secure Safety Lock: Automatic locking system engages during lifting and lowering to prevent accidental release.
• Locking Open & Closed: Clamp remains locked in both the open and closed position for safe handling and staging.
• Chain Shackle Design: Chain lifting shackle allows for flexible load angles and rigging configurations.
• Rugged Construction: Heavy-duty welded shell body made from high-grade alloy steel.
• Maintenance-Friendly: Easily serviceable with spare parts available from the manufacturer or authorized service centers.

Application Notes

• Designed for vertical lifting of a single plate only—never lift multiple plates simultaneously.
• Clamps should never be used on highly polished, greasy, dirty, or conical surfaces.
• When using multiple clamps, a spreader beam or equalizer is recommended for load balancing.
• Always inspect surfaces before use and clean contact areas to ensure maximum grip.

Maintenance & Safety

• Monthly Inspection: Check for jaw wear, spring integrity, deformation, and chain condition.
• Annual Overhaul: Must be inspected and, if needed, serviced by an authorized Terrier dealer or service center at least once per year to maintain warranty.
• 5-Year Warranty: Coverage applies to the original end user, provided proper inspection and maintenance records are kept.

Caution on Temperature

Note: The TNMK clamp uses polymer-based gripping pads that are sensitive to extreme temperatures. The specified operating range of –10°C to +60°C (14°F to 140°F) refers to the ambient working environment. Avoid lifting hot or cryogenically cold materials outside this range, as excessive heat or cold can degrade pad performance and compromise lifting safety. Contact the manufacturer for guidance on high- or low-temperature applications.
