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.

Dynamic ropes come in many different lengths. Construction block creel static kernmantle. Static rope meets or exceeds nfpa 1983 requirements. Dynamic rope is used to belay climbers and is designed to stretch under a heavy load to absorb the shock of a fallen climber.

Our 100 technora escape rope is one of the highest heat resistant ropes on the market making it optimal for search and rescue operations. Our new static master pro is a static kernmantle rope with a polyester core and cover. Because if its 100 polyester composition this rope has very low stretch yet is high strength. Kernmantle is derived from the german word kernmantel which means core and jacket.

Static ropes are designed to allow relatively little stretch which is most useful for applications such as hauling and rappelling. Fiber 100 high tenacity polyester htp. 3 strand 3 strand ropes are an inexpensive rope option. Any rope construction featuring a core and cover could be called kernmantle.

We offer many standard lengths and will happily prepare a custom length. We stock a fantastic 11mm dynamic line with a fall arrest peak of 11 2kn and an elongation of 26 89. The kernmantle rope is constructed with its interior core protected by an exterior braided sheath designed to optimize strength durability and flexibility. The properties of static kernmantle make it ideal for use as a life line or descent line.

The sheath is designed to generate some grab and friction for rappelling and lowering operations. Due to its construction it remains round through descent devices and allows minimal twist on the rope. Kernmantle construction may be used for both static and dynamic ropes. Like static ropes kernmantle construction is most common with materials such as nylon replacing natural fibres such as hemp.

It has a static kernmantle construction and is heat resistance up to 930 f with a loss of strength at. 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. Nbi s key product range is the manufacture of kernmantle static ropes. This safety rope is also very flexible and can be tied into tight knots.

Static kernmantle has very low stretch and works well for industrial applications. The term kernmantle is derived from the german words kern core and mantle cover.
