Self-Tightening Anti Twist Steel Rope Gripper Come Along Clamp with Heat Treated Alloy Steel Body for 11-30mm Rope

Anti Twist Steel Rope Gripper Come Along Clamp

On a long pull the rope is under tension and also under torque. A clamp that lets the rope rotate will slowly unwind the strand lay and weaken it. This anti twist gripper uses a self-tightening rack that grips harder as the load rises and holds the rope against rotation.

Product Overview

The body is heat treated alloy steel and the gripping rack is shaped so the load itself increases the clamping force. The series covers 11-30mm rope with rated loads from 50KN to 200KN. Because the clamp bites along the rope rather than at a single point, the strand is held without the local crushing that a simple jaw clamp produces.

Representative SKG configurations

Dimensions and ratings are nominal. Confirm the exact model against the datasheet before ordering.

Design Features and Field Benefits

• Self-Tightening Grip: The rack converts pull force into clamping force, so grip increases as tension rises and the rope does not slip at rated load.
• Anti Twist Rack Holds the Lay: The clamp resists rotation along the rope, which helps preserve strand lay and avoids the gradual untwisting that weakens a pull.
• Three Sizes Cover 11-30mm: A single series handles pilot rope through to heavy pulling rope, so the crew does not need a different clamp for each rope size.
• Heat Treated Alloy Steel Body: Heat treatment gives the strength and wear resistance needed for repeated use on high tension pulls.

Selection Guidance

• Match the clamp to the actual rope diameter and confirm the rated load against the pull tension.
• Do not exceed the rated load even briefly; shock loads can exceed the static figure.
• Inspect the rack teeth and rope surface after each use.

Typical Applications

• Transmission line stringing with steel rope
• Pilot rope and pulling rope handling
• Tension stringing operations
• Rope anchoring during construction

Quality Control and Delivery

Units are assembled in an ISO 9001 certified workshop. Frames are checked for sheave alignment and axle straightness, load bearing parts are inspected before assembly, and finished units are function checked before packing. Export packing is a plywood case with a moisture barrier, and a 12 month warranty covers manufacturing defects. Inspection records and, on request, third party load test certificates can be supplied with the shipment.
