Universal Screw Cam Clamp Double Eyes SCD type

No.1609

The Universal Screw Cam Clamp Double Eyes (SCD Type) is a highly versatile lifting device featuring a screw tightening and cam system, designed for all-purpose raising, lowering, lateral pulling, and turning operations.

  • Multi-Directional Lifting: Features two shackle holes (double eyes) positioned at different angles for flexible attachment and pulling in multiple directions.
  • Secure Gripping: Combines a threaded screw mechanism with a reliable cam system to provide an adjustable and secure clamping force.
  • Versatile Application: Easily adapts to move, lift, and turn workpieces, including objects with irregular or unknown shapes.
  • Robust Capacity: Built for durable, heavy-duty performance with working load limits ranging from 1 to 3.2 tonnes.
  • Technical Data

  • Safe Use of Lifting Clamp


Universal Screw Cam Clamp Double Eyes SCD type
*Double Eye Versatility: Allows for complex rigging angles, turning, and pulling in any direction.

Product Features

  • Double Eye Design: Features two lifting holes (eyes) for maximum versatility, allowing for pulling and lifting from different angles or accommodating complex rigging setups.
  • Screw Cam Mechanism: The screw-tightening mechanism provides a positive clamping force before the lift begins. This ensures the clamp stays securely attached even when there is no load or during vibrations.
  • Universal Application: Suitable for lifting, turning, and pulling steel plates, ship sections, and irregular steel shapes in any direction.
  • High Grip Strength: The circular cam gripping pad allows for a strong friction grip on the workpiece.
  • Safety Factor: Designed with a high safety factor for demanding industrial applications (e.g., shipbuilding, heavy fabrication).
  • Capacity Range: Available in capacities from 1 tonne to 3.2 tonnes.

Selecting the Correct Lifting Clamp

Lifting clamps utilize various mechanisms (lever, cam, roller, or screw) to provide a friction grip on the plate. When selecting a clamp, consider:

  • Type of Action: Lever, cam, roller, or screw.
  • Capacity & Thickness: Ensure the clamp is rated for the weight and the plate thickness.
  • Rigging: Determine if a pendant chain sling is required to provide articulation.

IMPORTANT: Minimum Load Requirement
Some clamps (especially cam action types) rely on a minimum load to engage the gripping force safely. Unless specified otherwise by the manufacturer:
• The load should not be less than 20% of the Safe Working Load (SWL).
• The plate thickness should not be less than 20% of the maximum jaw opening.

Safety Guidelines

Always

  • Inspect clamps and accessories before use and before storage.
  • Ensure the clamp is seated fully onto the plate (as far as it will go).
  • Position the clamp directly over the center of gravity of the load.
  • Ensure the locking mechanism is fully engaged/tightened before lifting.
  • Ensure the plate is fully supported and stable before releasing the clamp.
  • Store clamps in a dry, clean place protected from corrosion.

Never

  • Never use clamps on hard or polished plates unless specifically designed for them.
  • Never put packing/shims between the plate and the jaws.
  • Never lift more than one plate at a time in a single clamp.
  • Never lower from vertical to horizontal (or vice-versa) unless the clamp is designed for it.
  • Never obliquely side load a vertical clamp.
  • Never force or wedge the hoist hook into the eye of the clamp.

Operation & Maintenance

Using Clamps Safely

Do not use defective clamps. Place the clamp over the load center. If the plate is long and tends to bend, use two clamps with a spreader beam to prevent the clamps from twisting. Keep oil, grease, and contaminants away from the gripping jaws.

In-service Inspection

Regularly inspect for:

  • Wear, damage, or distortion to fixed and moving jaws.
  • Cracks in the frame or opening out of the body.
  • Insecure, worn, or bent pins and bolts.
  • Worn friction grip material (teeth).
  • Damaged locking levers or tight threads.
⚠️ WARNING: Teeth of jaws must NOT be re-sharpened or re-cut unless specifically approved by the manufacturer.
