Netherlands maritime ropes supplier, Lankhorst Ropes, claims to have enhanced the performance of its LankoForce rope with the introduction of the latest high modulus polyethylene (HMPE) yarns from Dyneema.
Using Dyneema SK78 fibers, Lankhorst claims, will significantly increase the rope’s strength retention factor and resistance to the small, repetitive shock loads encountered during towing.
LankoForce is widely used in maritime applications demanding high strength including mooring, towing, salvage and lifting. The strength of the 12 strand braided LankoForce rope is comparable to conventional steel wire ropes. However, it weighs one seventh of the weight of conventional steel wire ropes making it easier to handle. SK78 has a maximum strength rating of 35 cn/dtex compared with other HMPE yarns offering up to 30 cn/dtex, producing a stronger rope. The rope’s higher strength retention factor means the fibres are well suited to the small, repetitive shock loads encountered during towing.
“By switching to Dyneema SK78 we’re able to make a step change in the strength, resilience and creep performance of HMPE maritime ropes,” said Hans Pieter Baaij, commercial director, Lankhorst Ropes. “LankoForce has set a new standard for HMPE ropes, the introduction of SK78’s low yarn tolerance has produced a reliable and stable rope.”
LankoForce ropes are also available in a range of protective jackets where the rope is exposed to high levels of abrasion and resultant heat. Three types of jacket are available: polyester, Tipto and Dyneema. Lankhorst also offers LankoForce with the innovative Challenger coating, significantly reducing wear from abrasion. The absence of the jacket on the body of the rope makes it easier to inspect the rope and means the rope requires less maintenance, thus increasing the rope’s utility.
