Product Description
30KN Parallel Earth Wire Gripper: Non-Slip Come Along Clamp for GJ16-300 Steel Strand
Product Overview
The SKDP series Parallel Earth Wire Gripper is a premium, heavy-duty mechanical clamping tool engineered for the precise tensioning, sagging, and anchoring of overhead ground wires (OHGW) and galvanized steel strands. Featuring extra-long, dual opposing parallel jaws with specialized antiskid surface processing, this gripper provides a massive surface contact area. It is uniquely equipped with a pre-tightening force mechanism (internal spring tensioner) that prevents initial line slippage on loose wires, transferring full mechanical load safely up to 30KN without scoring or shearing high-tensile steel strands.
Technical Specifications
Precision calibrated to ensure industrial compliance across an ultra-wide range of heavy-duty steel wire gauges:

| 14242 | SKDP-2 | GJ Steel Strand / Earth Wire | GJ 70 - GJ 150 Steel Strand | 20 KN | 2.2 kg |
| 14243 | SKDP-3 | GJ Steel Strand / Earth Wire | GJ 185 - GJ 300 Steel Strand | 30 KN | 3.8 kg |
- Body Material: Industrial-Grade Hardened Forged Steel
- Clamping Mechanism: Multi-Link Lever Parallel Jaw Closing Action
- Special Safety Feature: Built-in Pre-Tightening Spring System
- Surface Coating: Antiskid Anti-Corrosion Finish
Key Technical Advantages
- Extended Parallel Squeezing Plates: Unlike short, aggressive jaws that kink wires, the SKDP series utilizes elongated parallel clamping plates. This layout distributes the crushing pressure linearly over a long segment, securing the wire while safeguarding individual wire layers.
- Pre-Tightening Spring Mechanism: Addresses the common risk of grippers dropping off during initial alignment when the wire line is still slack. The integrated spring exerts a constant baseline squeeze, keeping the wire locked before the main hauling load kicks in.
- Massive Gauge Versatility (Up to GJ300): Engineered to handle extreme wire profiles up to GJ-300 structural steel strands, a capability rarely found in standard consumer-grade wire grips.
- All-Weather Structural Reliability: Forged with heavy-duty steel links and a hardened pin axis to resist deformation, jamming, or corrosion in coastal, high-salinity, and alpine utility corridors.
Industrial Applications
- Overhead Transmission Grid Setup: Sagging and pulling overhead ground wires (lightning wires) on lattice steel towers.
- Guyed Tower Guy Wire Anchoring: Securing and tightening structural stay/guy wires on telecom, radio, and power transmission masts.
- Substation Anchor Span Assemblies: Tensioning terminal dead-end ground connections.
Professional Buyer FAQ
Q1: What is the main benefit of the Pre-Tightening Force System on the SKDP gripper?
On typical parallel come along clamps, if the operator stops pulling and the cable goes slack, the jaw might lose grip and slide or fall off. The SKDP's built-in pre-tightening spring ensures that even with zero external hauling tension, the jaws maintain an active hold on the steel strand, drastically enhancing overhead safety.
Q2: Can I use this parallel gripper to pull OPGW optical fiber cables?
No. The SKDP series features a high-hardness, micro-textured steel surface treated with an antiskid process designed for tough galvanized GJ steel strands. While it is gentle on steel strands, it is too aggressive for the softer aluminum-clad exterior of OPGW or insulated cables. For OPGW, please use our dual-cam curved wedge gripper (SKDS series).
Q3: How do the long parallel plates prevent wire deformation under a 30KN load?
Clamping force is inversely proportional to contact surface area (Pressure = Force / Area). By extending the parallel plates horizontally, the SKDP-3 disperses a heavy 3-ton (30KN) load along a wide linear contact path rather than a single crush point. This prevents the steel strand from deforming or snapping under maximum tension.
