Kernmaster™ - 1 Pages

  1. P. 1

Catalogue excerpts

Static-rappelling Kernmaster line is constructed with a traditional "mantle" sleeve consisting of 48 strands of polyester. The inside, or "kern," is a braided core of energy-absorbing nylon. The core is fully steam-stabilized to enhance the rope's flexibility and prevent hardening in service; the braid also bends more easily and with less fatiguing of the core when cycled over sheaves or dropped over a parapet. Sleeve is either white or solution-cast fiber (color added prior to yarn production) which makes for lasting colors and enhanced wear resistance. Standards: Break Strength Break Strength Working Load * Knots and abrupt bends significantly reduce the strength of all ropes and lowers maximum working load. * * For situations where a man is on the rope, cut these working loads in half. 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 constitutes hazardous shock load and would void normal working load recommen- dation. Consult Yale Cordage for guidelines for working loads and safe use of rope. Energy Absorption The colored area under the curve represents the rope's energy-absorption capability. ■ Green working 622 ft. lbs./lb. maximum allowable leakage 500 Micro Amperes when impurities will increase ropes conductivity dramatically. Available with factory splices. Maximum Working Load Minimum Break Strength Average Break Strength
