    Key Features

    Our stainless steel wire rope clips (also known as wire rope clamps / cable clamps / bulldog grips) are manufactured from AISI 304/316 stainless steel or Q235 carbon steel, with strength grades covering A2‑70 (304), A4‑80 (316) and carbon steel grades 4.8/8.8. The classic U‑bolt + saddle plate design accommodates wire rope diameters from 2mm to 60mm, complying with GB/T 5974, DIN 741, EN 13411‑5, RR‑C‑271 and other international standards. These clips are specifically developed for lifting & hoisting, marine & offshore, outdoor cable structures, and industrial equipment. The 316 stainless steel variant resists chloride corrosion (salt spray test ≥720h), ensuring long‑term safety in submerged or humid environments.

    Easy installation: Form an eye loop with the wire rope, insert the loop into the U‑bolt, fit the saddle plate, and tighten the nuts evenly – typically the first nut is placed closest to the rope eye, followed by sequential tightening. Finally perform a load test to verify no slippage. The anti‑vibration & anti‑loosening design combines controlled preload and a serrated saddle plate.

    Precision Manufacturing Process

    The core component of the wire rope clip—the U‑bolt—is formed from high‑quality wire rod (304/316 stainless steel or Q235 carbon steel) using a multi‑station cold bending machine in a single operation, ensuring parallelism and symmetry tolerances ≤0.3mm between the two arms. Threads are rolled by a high‑speed planetary thread rolling machine with precision‑ground carbide dies (accuracy ±0.005mm), increasing fatigue strength by 30% compared to cutting processes. The saddle plate is produced via precision stamping + deburring, with internal anti‑slip serrations to enhance gripping force.

    Carbon steel versions (grade 8.8) undergo mesh‑belt furnace heat treatment (quenching + medium‑temperature tempering) to reach HV 250‑320. Stainless steel versions (A4‑80) receive vacuum solution treatment + passivation to eliminate intergranular corrosion risk. Surface finishing: carbon steel parts can be electro‑galvanized (8‑12μm, 72h salt spray) or hot‑dip galvanized (≥50μm, 500h salt spray) ; stainless steel parts are electropolished to improve surface finish and passive film density. Every batch undergoes 100% go/no‑go thread inspection and assembly torque verification to ensure smooth, jam‑free nut movement on the U‑bolt.

    Transparency & Customization

    We offer full traceability: each box of wire rope comes with a test report (material spectrum, hardness, salt spray time, thread clearance rate), and the packaging QR code allows traceability to the original furnace number, forging batch, and operator. Our independent website provides real-time video of the forging workshop and typical failure cases (such as screw breakage due to over-twisting).

    Customization options: We support non-standard U-bending radii, extended or shortened screw lengths; and can mix and match any GB/DIN/EN standard (e.g., DIN marking on the head, EN 13411-5 on the tail). Surface treatments include a "Marine Package": 316 stainless steel + localized tin plating for electrochemical corrosion protection, or carbon steel with zinc plating + Dacromet coating + sealing layer.

    Multi-Material & Full-Size Coverage for Demanding Conditions & Long-Term Durability

    Our wire rope clips are available in two major material series: AISI 304/316 stainless steel and Q235 carbon steel. Stainless steel grades include A2-70 (304) and A4-80 (316); the 316 variant offers exceptional chloride corrosion resistance, passing ≥720 hours of salt spray testing to withstand highly corrosive marine environments. Carbon steel options in grades 4.8/8.8, with optional electro or hot-dip galvanizing, balance high strength and rust protection. Suitable for wire rope diameters from 2mm to 60mm, they deliver reliable grip for lifting, rigging, and outdoor cable applications.

    Standardized U-Bolt Design with Anti-Slip & Anti-Loosening Features

    Featuring a classic U-bolt and serrated saddle plate structure, our clips comply with international standards including GB/T 5974, DIN 741, and EN 13411-5. The serrated saddle ensures uniform, high-traction clamping force to prevent wire rope slippage under load. Anti-loosening performance is enhanced by controlled pre-torque and tooth engagement, maintaining stability even in dynamic lifting and industrial applications. This design eliminates the risk of loosening or dislodgement, providing robust safety redundancy for critical lifting operations.

    Easy Installation & High Versatility for All On-Site Scenarios

    Installation is quick and straightforward: simply form an eye in the wire rope, insert the U-bolt, fit the saddle plate, and evenly tighten the nuts per standard procedures, with no complex tools required. This significantly reduces on-site installation time and labor costs. With broad compatibility for various wire rope diameters, stainless steel clips perform reliably in wet environments without additional coatings, while galvanized carbon steel versions suit outdoor use. They are widely applicable in marine, construction, and industrial settings, offering excellent versatility and construction efficiency.
