Wire rope clamps secure the ends of wire ropes by clamping the dead end back to the live end, creating loops or extending ropes for lifting, pulling, and load-securing applications across construction, energy, and infrastructure industries.
Common designs include the U-bolt style, featuring a U-shaped bolt with saddle and nuts, and the fist grip style, which uses bolts and heavy hex nuts allowing full wrench arc movement during installation. U-bolt clamps must be installed with the base on the live end and the U-bolt on the dead end to prevent rope damage, while fist grip clamps offer orientation flexibility. Materials include forged steel, cast steel, or stainless steel, with zinc plating or galvanizing for corrosion resistance.
Key features include self-gripping wedge mechanisms with slightly serrated jaws that provide positive locking, immediate position adjustment, and rope-preserving design that maintains high safety factors. Clamps accommodate wire rope diameters from 3/16 inch to 13/16 inch, with load capacities ranging from 2,200 to 6,600 pounds.
Proper installation requires spacing clips approximately six wire rope diameters apart and applying correct torque for secure attachment. Compliance with standards like American Society of Mechanical Engineers (ASME) B30.26 ensures effective holding power. Wire rope thimbles are often used with clamps to prevent kinking at loop terminations.

Frequently Asked Questions (FAQS)
What is a wire rope clamp used for?
Wire rope clamps secure the loose ends of wire rope, create an eye at the end, quickly lengthen wire ropes or slings, and clamp the dead end back to the live end. They are essential for terminating wire rope in various applications.
What are the different types of wire rope clamps available?
The main types include traditional U-bolt and saddle clamps, and fist grip style clamps. Traditional clamps have a U-bolt and saddle secured with nuts, while fist grip style allows for easier installation with bolts and heavy hex nuts that can be swung in a full arc.
What industry standards do your wire rope clamps comply with?
Our wire rope clamps meet or exceed ASME B30.26 requirements and comply with US, EN, DIN, and JIS standards. RaxPower employs strict quality control with multi-stage testing and 100% quality review to ensure extreme reliability and full standards compliance for critical applications like grid maintenance and infrastructure projects.
What materials are wire rope clamps made from, and how do they affect corrosion resistance?
Wire rope clamps are made from forged steel, zinc-plated steel, galvanized steel, and stainless steel (types 304 and 316). Zinc-plated is suitable for dry applications but may rust quicker. Galvanized offers durability and affordability with moderate corrosion resistance. Type 304 stainless steel is for moderate exposure, while marine-grade type 316 provides maximum corrosion resistance. RaxPower uses advanced hot-dip galvanizing with smooth, bright surfaces and a mean coating thickness exceeding 85 microns for articles over 6mm, ensuring long-term durability in demanding conditions like marine, industrial, or outdoor settings.
What is the capacity of wire rope clamps?
Capacities vary by model, with common capacities including 1 ton / 2,200 lbs, 2 ton / 4,400 lbs, and 3 ton / 6,600 lbs. Specific capacities depend on the wire rope range and clamp design.
What size wire rope clamp do I need?
The clamp size should match the diameter of your wire rope. For instance, for a 5/8 wire rope, use a 5/8 clamp. Available sizes typically range from 3/16 to 13/16 or larger.
How do I properly install a wire rope clamp?
For U-bolt clamps, attach the first clip one base width from the dead end, tighten the nuts securely with the U-bolt saddling the dead end and the base on the live end. Space clips about six wire rope diameters apart, tighten before tension and after loading. Use a wire rope thimble in the eye to prevent kinking.
What processes ensure consistent quality and strength in your wire rope clamps?
Our wire rope clamps are manufactured using hot forging and drop-forging techniques for greater strength and accurate sizing. RaxPower implements strict quality control with raw material selection, multi-stage testing, load tests, and gauge tests per IEC 120 standards, along with passed SGS tests, ensuring perfectly consistent quality that protects your brand and provides cost savings for OEM and manufacturing needs.
Can you handle large bulk orders for infrastructure projects with on-time delivery?
Yes, we can handle bulk orders and offer competitive project-based pricing for large-scale projects. RaxPower has extensive production facilities, including 17,000 square meters of workshops and 5,000 square meters of warehouses, and utilizes automatic machines and efficient processes to ensure accurate sizing, uniform hardware, and reliable on-time delivery for entire orders.
