Product Description
The SKG30L Bolt Type Anti-Twist Steel Rope Gripper is a high-rigidity, mechanical wire-pulling clamp specifically developed for high-voltage overhead transmission line stringing. Designed exclusively for flat/square braided anti-twisting steel ropes (Φ13mm), this gripper replaces traditional automatic levers with a heavy-duty bolt fastening mechanism. By manually tightening the high-tensile bolts, it delivers an immovable, positive compression seal that eliminates initial slack-slippage, ensuring absolute structural safety and up to 30KN of reliable load-holding performance during tension operations.
Precision machined to guarantee strict mechanical safety thresholds under rigorous field pulling demands:

- Fastening Structure: High-Tensile Bolt & Nut Locking System
- Inner Cavity Profile: Specialized Rectangular Slot
- Body Material: Industrial-Grade Heavy Forged Alloy Steel
- Zero-Slip Bolt Fastening: Unlike automatic come-along clamps that can spring open or slip when line tension drops to zero, the bolt-locked side plates maintain constant, unyielding mechanical pressure until manually released.
- Flatted Rectangular Jaw Slot: The interior clamping chamber is precisely shaped to mirror the rectangular profile of anti-twist woven steel ropes. This full-surface contact protects the outer mesh layers from localized crushing.
- Interlocking Side Plate Defense: The solid dual-plate design encloses the rope completely before bolting, acting as a structural shield that prevents the pilot wire from popping out under sudden whip or impact loads.
- Simplified Link-Free Mechanics: With zero complex linkages, slides, or springs, this gripper is completely immune to jamming, seizing, or wearing down in muddy, sandy, or high-dust overhead utility corridors.
- Tension Stringing Systems: Temporary anchoring, splicing, and securing of Φ13mm anti-twist steel pilot ropes on lattice towers.
- Overhead Line Sag Adjustments: Maintaining precise holding tension on multi-braided steel wire systems during initial line deployment.
- Heavy Utility Maintenance: Fail-safe grid line tensioning for urban and cross-terrain transmission grid construction.
Lever-type grippers require active line tension to stay locked. If the line goes completely slack during stringing, the jaws can loosen. The bolt-type SKG30L enforces a rigid, positive lock via thread torque, meaning it stays 100% clamped regardless of external tension fluctuations, offering unparalleled static anchoring security.
No. The SKG30L features a dedicated rectangular slot tailored for the square/flat cross-section of braided anti-twisting wire ropes. Inserting a standard round rope reduces the contact to mere point-loading, which will drastically decrease friction, cause slippage, and severely deform the round strands.
It utilizes standard high-tensile industrial heavy hex bolts. Linemen can easily fasten or release the mechanism using standard utility impact wrenches, ratchets, or traditional open-end box wrenches found in any standard overhead powerline tool kit.
