MO-CLAMP Self-tightening Clamp System - Important Information


For more information contact us for fast and friendly attention and service.

FLEET-HYDROL is the Australian agent for MO-CLAMP Self-tightening Clamp System, the original and patented wedge-pulling ring.

=  All items are drop-forged for maximum strength & durability.
=  Design allows the wedge to turn during use, avoiding unwanted twists and bends and allowing a straight pull line to enhance precision and the life of the equipment.

MO-CLAMP products are available in three configurations:

=  “Gater” tooth – aggressive design for holding structural components in areas where repair is not visible after job completion.

=  “Horizontal” tooth – for a secure grip on all metal surfaces. Some products feature an angled horizontal tooth design.

=  “Cross-hatched” tooth – aggressive design for sheet metal and lightweight components. Grips securely, but with less deformation than with “gater” design.


WARNING – Never stand within two metres in any direction of a chain under tension. ALWAYS use secondary safety ties for the chain.
=  Always monitor anchor locations during a pulling operation.
=  Watch for separating weld seams – usually identified by “popping” noises.
=  Remove all grease or paint from attachment points.
=  Minimise backlash from a loose chain or clamp, wrap with safety chains, blankets or tarps.
=  Never overload equipment – see inspection procedures below.

Clamp Maintenance
=  Keep teeth free of dirt, grease & paint by cleaning with a wire brush. Store on a tool board or rack.
=  Lubricate bolts & nuts with authorised anti-seize compound.
=  Sharpen teeth with a sharp triangular file.
=  Check clamp nuts & bolts frequently, These are always the items to wear most under extreme loads, so tighten & replace with authorised MO-CLAMP components as required.

Chain Usage & Maintenance
=  ALWAYS inspect chain prior to use. Nicks, gouges, twists, stretching or excessive wear are DANGER SIGNS.
=  Avoid making sharp turns/corners that could cause excessive strain and breakage.
=  Avoid twists that will measurably reduce the tensile strength.
=  Apply smooth pressure and avoid sudden jerks that may overload the chain.
=  DO NOT OVERLOAD.  This causes stretching and reduces strength. If a chain has been overloaded, inspect it immediately and remove from service if damaged.
