7-Flex

Improved resistance to bending fatigue over general purpose ropes

Good resistance to wear and fatigue are required for trip ropes on mining shovels. 7-Flex and 7-Flex PFV have the best characteristics to maximize rope service life in this application. The 7-Flex construction offers improved resistance to bending fatigue and the PFV plastic-impregnated feature further enhances service life and make the operation cleaner.
