Static Kernmantle Rope Construction
This safety rope is also very flexible and can be tied into tight knots.
Static kernmantle rope construction. We offer many standard lengths and will happily prepare a custom length. 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. Kernmantle kernmantle ropes are the most common construction for dynamic climbing ropes.
The term kernmantle is derived from the german words kern core and mantle cover. A firm but flexible kernmantle construction static rope is designed to meet the demands of rescue rappelling and specialty rigging operations. 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. Dynamic rope is used to belay climbers and is designed to stretch under a heavy load to absorb the shock of a fallen climber.
The kernmantle rope is constructed with its interior core protected by an exterior braided sheath designed to optimize strength durability and flexibility. Our 100 technora escape rope is one of the highest heat resistant ropes on the market making it optimal for search and rescue operations. Nbi s key product range is the manufacture of kernmantle static ropes. Our new static master pro is a static kernmantle rope with a polyester core and cover.
3 strand 3 strand ropes are an inexpensive rope option. Static ropes are designed to allow relatively little stretch which is most useful for applications such as hauling and rappelling. Kernmantle construction may be used for both static and dynamic ropes. The sheath is designed to generate some grab and friction for rappelling and lowering operations.
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. 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. Common life safety or fall arrest ropes feature a twisted parallel strand core surrounded by a braided cover.
Static kernmantle has very low stretch and works well for industrial applications. Dynamic ropes come in many different lengths. Construction block creel static kernmantle. Due to its construction it remains round through descent devices and allows minimal twist on the rope.
Like static ropes kernmantle construction is most common with materials such as nylon replacing natural fibres such as hemp. Static rope meets or exceeds nfpa 1983 requirements.
