Static Kernmantle Rope Construction

Common life safety or fall arrest ropes feature a twisted parallel strand core surrounded by a braided cover.

Static kernmantle rope construction.

Like static ropes kernmantle construction is most common with materials such as nylon replacing natural fibres such as hemp. 3 strand 3 strand ropes are an inexpensive rope option. We offer many standard lengths and will happily prepare a custom length. They feature a tight 32carrier 40carrier or 48carrier cover to protect the core from any ingress of dirt or particles that might harm the core.

Construction block creel static kernmantle. Static rope meets or exceeds nfpa 1983 requirements. Because if its 100 polyester composition this rope has very low stretch yet is high strength. Dynamic rope is used to belay climbers and is designed to stretch under a heavy load to absorb the shock of a fallen climber.

Kernmantle kernmantle ropes are the most common construction for dynamic climbing ropes. Sheath 32 strand braided with half the strands having a left z twist and the other half having a right s twist for a balanced torque free rope with maximum abrasion resistance. Static kernmantle has very low stretch and works well for industrial applications. The sheath is designed to generate some grab and friction for rappelling and lowering operations.

Our new static master pro is a static kernmantle rope with a polyester core and cover. A firm but flexible kernmantle construction static rope is designed to meet the demands of rescue rappelling and specialty rigging operations. Due to its construction it remains round through descent devices and allows minimal twist on the rope. Dynamic ropes come in many different lengths.

Fiber 100 high tenacity polyester htp. It has a static kernmantle construction and is heat resistance up to 930 f with a loss of strength at. Kernmantle is derived from the german word kernmantel which means core and jacket. The term kernmantle is derived from the german words kern core and mantle cover.

The properties of static kernmantle make it ideal for use as a life line or descent line. Any rope construction featuring a core and cover could be called kernmantle. We stock a fantastic 11mm dynamic line with a fall arrest peak of 11 2kn and an elongation of 26 89. Nbi s key product range is the manufacture of kernmantle static ropes.

The kernmantle rope is constructed with its interior core protected by an exterior braided sheath designed to optimize strength durability and flexibility. Kernmantle construction may be used for both static and dynamic ropes.
