Large Braits
Yale is pleased to announce its acquisition and installation of equipment necessary to produce large diameter plaited ropes. Our capability in these styles of ropes, widely accepted in smaller diameters, now continues through five inch diameter, or 15" circumference. This page provides our preliminary data for these styles of ropes. The first, Nylon Brait, in sizes 6" thru 15" circumference is based on Nylon 6-6 and is a four stage rope, laid firm and easily spliced. The second, Polyester Brait, is also a 4-stage rope based on PET high tenacity yarn offering exceptional tension fatigue especially wet. The third rope is a plaited Ultra High Molecular Weight Polyethylene (UHMPE) which employs Honeywell's Spectra fiber. Spectra is one of the strongest fibers known and is very low elongating. The geometry of the plaited UHMPE allows more substantial dynamic loads to be imparted on the rope without compromising its longevity. Keep abreast of these ropes and others, notably our Unitrex XS-8.

* Knots and abrupt bends significantly reduce the strength of all ropes and lowers the maximum working load.
** Working load is based on static or moderately dynamic lifting/pulling operations. Instant changes in load up or down in excess of 10% of the rope's rated working load constitutes hazardous shock load and would void normal working load recommendation. Consult Yale Cordage for guidelines for working loads and safe use of rope.
