ROPE MADE OF TEXTILE FIBRE MATERIAL
The invention relates to a rope (1) made of textile fibre material, which is characterized by the combination of features whereby
a) the load-bearing fibre material of the rope (1) consists of high-strength synthetic fibres
b) the rope (1) is in the form of a spiral strand rope
c) the rope (1) has at least two, preferably at least three concentric load-bearing strand layers (3,4,5)
d) the individual strands (7,8,9,10,11,12) of the strand layers (3,4,5) are movable with respect to one another
e) the degree of filling of the rope (1) with textile fibre material is ≧75%, preferably ≧85%
f) the outermost ply (5,6) of the rope has a coefficient of frictionμ with respect to steel of μ<0.15.
Synthetic fiber rope
A synthetic fiber rope comprising:—a core, said core being a laid or braided synthetic fiber strand,—a polymer layer, said polymer layer covering said core,—a first layer, said first layer having at least six first synthetic fiber strands laid in a first direction surround said polymer layer, and—a second layer, said second layer having at least twelve second synthetic fiber strands laid in a second direction surround said first layer.
SMALL DIAMETER CABLE
A wire cable construct including a plurality of strands each made of a plurality of wire filaments, the strands and wire filaments arranged in a 37×7 configuration of 37 strands of 7 wire filaments each, with the strands arranged in four layers including a first, central layer of a single strand, a second layer of six strands, a third layer of twelve strands and a fourth, outermost layer of eighteen strands. The cable may have a small diameter for use in medical device applications, and the strand and wire element configuration allows the cable to carry high axial loads, minimizes bending stress when the cable is routed around a tight turn such as a small pulley, and minimizes torsion in the cable due to axial loading.
SYNTHETIC FIBER ROPE
A synthetic fiber rope comprising:a core, said core being a laid or braided synthetic fiber strand,a polymer layer, said polymer layer covering said core,a first layer, said first layer having at least six first synthetic fiber strands laid in a first direction surround said polymer layer, anda second layer, said second layer having at least twelve second synthetic fiber strands laid in a second direction surround said first layer.
