Yale Ultrex Winch Line

Yale Ultrex 10mm Winch Line with Chook

Stronger than steel, floats on water.

Available in 30m, 45m or 60m with a Yale chippable Chook.

Ultrex is a 12-strand single braid of Ultra High Molecular Weight Polyethylene (UHMWPE) fiber enhanced with Yale's Maxijacket High Performance coating, which supplies superior abrasion resistance. Additional abrasion resistance is attributed to the larger filament diameter. In comparable yarn sizes Ultrex will contain roughly half as many individual filaments compared to similar products. Each of these individual filaments are more cut resistant than the finer filaments in other products and manifest improved abrasion resistance in the larger rope product. Ultrex's braid angles and twist level are designed to optimize break strength and keep stretch low.

UHMWPE is the most forgiving high-modulus fiber, giving better sheave-cycling capabilities than other high-tech fibers. Ultrex has zero water absorption and maintains its flexibility even in freezing conditions. As is the case for most Yale ropes, the strengths shown in the charts are for spliced ropes.

Ultrex Chook

The Ultrex winch line featuring the Chook is the leading solution for your chipper winch needs. We created the Chook to succeed the traditional steel hook that is generally used with chipper winch lines.

This revolutionary connector allows users to easily choke off the load, either directly to the winch line, or preferably by use in conjunction with a sling. The Chook is made from a high-density polymer, creating a 2,200-pound working load and decreasing the potential of equipment damage. As with any chipper hook, proper and safe practices are required when the Chook is in use.

* Knots and abrupt bends significantly reduce the strength of all ropes and lower maximum working load.

** Working load is based on static or moderately dynamic lifting/pulling operations. Instantaneous changes in load, up or down, in excess of 10% of the rope's rated working load constitute hazardous shock load and would void the normal working-load recommendation. Consult Yale Cordage for guidelines for working loads and the safe use of rope.
