Static Kernmantle Rope Construction

The term kernmantle is derived from the german words kern core and mantle cover.

Static kernmantle rope construction.

Common life safety or fall arrest ropes feature a twisted parallel strand core surrounded by a braided cover. The kernmantle rope is constructed with its interior core protected by an exterior braided sheath designed to optimize strength durability and flexibility. We offer many standard lengths and will happily prepare a custom length. Our 100 technora escape rope is one of the highest heat resistant ropes on the market making it optimal for search and rescue operations.

Construction block creel static kernmantle. 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. 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 ropes come in many different lengths.

Fiber 100 high tenacity polyester htp. This safety rope is also very flexible and can be tied into tight knots. The sheath is designed to generate some grab and friction for rappelling and lowering operations. It has a static kernmantle construction and is heat resistance up to 930 f with a loss of strength at.

Like static ropes kernmantle construction is most common with materials such as nylon replacing natural fibres such as hemp. Static kernmantle has very low stretch and works well for industrial applications. Dynamic rope is used to belay climbers and is designed to stretch under a heavy load to absorb the shock of a fallen climber. We stock a fantastic 11mm dynamic line with a fall arrest peak of 11 2kn and an elongation of 26 89.

Our new static master pro is a static kernmantle rope with a polyester core and cover. Static ropes are designed to allow relatively little stretch which is most useful for applications such as hauling and rappelling. Kernmantle is derived from the german word kernmantel which means core and jacket. 3 strand 3 strand ropes are an inexpensive rope option.

Static rope meets or exceeds nfpa 1983 requirements. The properties of static kernmantle make it ideal for use as a life line or descent line. Kernmantle kernmantle ropes are the most common construction for dynamic climbing ropes. Due to its construction it remains round through descent devices and allows minimal twist on the rope.

Because if its 100 polyester composition this rope has very low stretch yet is high strength. Any rope construction featuring a core and cover could be called kernmantle.
