Rainbow Line is a twelve-strand HMPE (High Modulus Polyethylene) rope made from SK75 Dyneema® fibers. Our Rainbow Line has an unmatched weight-to-strength ratio. Compared to a steel wire rope of the same size, it will match the breaking strength at only 15% of the weight.
The high-visibility green coating is intended as a safety feature to maintain line visibility even after heavy use. With a specific gravity of 0.98 it is the lightest/strongest rope available and even floats on water.
It also features excellent resistance to abrasion, UV, salt water, bending and tension fatigue. Rainbow Line is widely used in both surface and deep mining operations including recovery lines, tow lines, shield hawing lines, winch lines or almost any man-handled wire rope application where reduced weight will be of benefit.
