Static Kernmantle Rope Strength
Low elongation or static ropes are a core element of any work at height system.
Static kernmantle rope strength. Kernmantle kernmantle rope consists of twisted parallel fibers the kern surrounded by a tightly braided sheath the mantle. This safety rope is also very flexible and can be tied into tight knots. Kernmantle rope from german kern meaning core and mantel meaning sheath is rope constructed with its interior core protected by a woven exterior sheath designed to optimize strength durability and flexibility. Static pro lifeline specifications the following specifications apply to all diameters of cmc static pro lifeline.
Explain the uses and limitations of static kernmantle rescue rope. Demonstrate the correct procedure for tying the following knots and hitches. The core fibers provide the majority about 70 of the rope s strength. Fiber 100 high tenacity polyester htp.
In 1998 the cordage institute published standard ci 1801 low stretch and static kernmantle life safety rope which defined a static rope as having a maximum 6 elongation at 10 of the rope s minimum breaking strength mbs. Our new static master pro is a static kernmantle rope with a polyester core and cover. There are two distinct types of kernmantle. Because if its 100 polyester composition this rope has very low stretch yet is high strength.
We have been making the highest quality and most innovative static ropes for decades. Construction block creel static kernmantle. The core fibers provide the tensile strength of the rope while the sheath protects the core from abrasion during use. The kernmantle rope is constructed with its interior core protected by an exterior braided sheath designed to optimize strength durability and flexibility.
Identify various rope rescue hardware components and explain its use. Rope strength force is anything that can cause a moving object to. The sheath is tightly braided providing significantly higher abrasion resistance. There are two distinct types of kernmantle.
Nbi s key product range is the manufacture of kernmantle static ropes. Kernmantle rope consists of twisted parallel fibers the kern surrounded by a tightly braided sheath the mantle. Sterling htp rope is popular with the growing number of tree climbers who are using single rope entry and work climbing techniques. The sheath is tightly braided providing significantly higher abrasion resistance.
Certification ul classified to nfpa 1983 standard on life safety rope and equipment for emergency services 2017 edition. Kernmantle is derived from the german word kernmantel which means core and jacket. The sterling name has become synonymous with durability and reliability across multiple industries at all job sites. Sterling htp static kernmantle rope is an excellent single rope ascent and work line.
Htp gets its name from its high tenacity polyester construction.
