Abstract:
A rope system (10, 20) comprising a splice structure (12, 22) with an intact portion (23) comprising at least 8 intact strands (32, 34), and a disassembled portion (26) comprising at least 4 loose strands (30), wherein the intact portion (23) is a braid of at least 4 S oriented (32) and at least 4 Z oriented intact strands (34), wherein at least one loose strand (30) of the disassembled portion (26) passes under and over intact strands (32, 34) of the intact portion (23), and at least one loose strand (30) passes under at least one X-tuck (38) of intact strands (32, 34). By this means the splice length can be minimized resp. slippage of the splice at high loads can be avoided.
Abstract:
A method for impregnating a liquid material (105) into a rope (101) comprising a plurality of fibers and interstices between said fibers, said method comprising the steps of: (a) Providing a liquid material in a tank, (104) said liquid material defining a level of liquid (105-1) in said tank (104); (b) Providing an impregnation unit (103) containing a chamber (106) at least partially immersed in said liquid material (105), said chamber (106) comprising: (i.) a rope-inlet (107) for at least partially tightly receiving the rope (101), wherein said rope-inlet (107) is positioned below the level of liquid (105-1); (ii) a rope-outlet (108) for at least partially tightly discharging said rope (101); iii) a vacuum-outlet (109); and (c) Providing a vacuum-device operatively connected to said vacuum-outlet (109) for lowering the pressure in said chamber (106) below the atmospheric pressure; (d) Passing the rope (101) through the liquid material (105) in the tank (104) and then inside and outside said chamber (106) via the rope-inlet (107) and rope-outlet (108), while maintaining the pressure inside said chamber (106) below the atmospheric pressure to force the liquid material (105) to fill at least part of said interstices between the fibers of the rope (101) by penetrating between said fibers. A corresponding device, rope an use of the rope is also disclosed.
Abstract:
Methods for impregnating a liquid material into a rope are provided whereby a liquid material is provided in a tank which defines the liquid level in the tank. An impregnation unit containing a chamber at least partially immersed in the liquid material includes a vacuum-device operatively connected to the vacuum-outlet of the chamber so as to lower the pressure in the chamber below atmospheric pressure. The rope may therefore be passed through the liquid material in the tank and then inside and outside the chamber via the rope-inlet and rope-outlet of the chamber, while maintaining the pressure inside the chamber below the atmospheric pressure to thereby force the liquid material to fill at least part of the interstices between the fibers of the rope by penetrating between the fibers.
