Patent ID: 8794387

Claim:
A traction system comprising: at least one traction sheave having grooves; at least one composite rope having individual ropes arranged in parallel; said individual ropes each having a first diameter (d) and each being jacketed with an elastomer jacket layer of a predetermined thickness (u) so as to provide tension members, each member having an overall diameter; said tension members each having: a first side; a second side facing away from said first side and said grooves of said traction sheave; and, a predetermined length; said tension members being configured to engage in corresponding ones of said grooves of said traction sheave at said first side; an elastomer connecting layer connecting said tension members to each other over substantially an entirety of said length of said tension members; said elastomer connecting layer being arranged only on said second side of each of said tension members; said tension members being configured to engage in corresponding ones of said grooves of said traction sheave with a penetration depth of at least 25% of said diameter (d) of said individual ropes; said elastomer jacket layer of said individual ropes at said first side having a thickness (u) lying in a range of 0.2 mm to 2 mm; and, said elastomer connecting layer having a width that is smaller than an overall width of said composite rope.
