Definitions

  • Dragline and shovel ropes are a very specific and specialised type of industrial rope used with excavators in mining in a variety of circumstances to pull and move heavy loads. They can take the form of dragline drag and hoist ropes, dump ropes, dragline Intermediate Boom Suspension (IBS), shovel ropes and dragline main suspension ropes. Shovel hoist and crowd and retract ropes are also included.
  • Existing dragline ropes include a core and either 6 or 8 outer strands around the core. This leaves a significant empty space and low steel fill factor across the nominal diameter of the dragline rope due to the space between abutting strands. Due to the relatively large diameter of the outer strands in a 6 or 8 strand rope fatigue is an issue and weakness for existing draglines.
  • the dragline rope have a larger cross- sectional area, resulting in a stronger rope and reduces fatigue compared to lower numbers of outer strands due to reduced operating stresses.
  • the at least nine strands also allows the independent wire rope core to be larger and the dragline rope more flexible.
  • Having at least nine outer strands provides a larger contact surface area between the outer strands and the independent wire rope core reducing internal contact stresses and improved fatigue endurance.
  • the independent wire rope core includes a wire main core and a plurality of core strands wound around the wire main core.
  • the independent wire rope core comprises at least 6 strands.
  • the independent wire rope core comprises up to 18 core strands.
  • the dragline rope includes wormings placed between the core and each of the outer strands.
  • the core is plasticated.
  • the outer wires are compacted.
  • Ropes with 9 outer strands or more typically have less wires in the outer strand which increases the ropes overall resistance to crushing and deformation of the outer strand, especially in larger diameter ropes.
  • Figure 1 is cross sectional view of a dragline rope according to a first embodiment of the present invention
  • Figure 2 is cross sectional view of a dragline rope according to a second embodiment of the present invention
  • Figure 4 is cross sectional view of a dragline rope according to a fourth embodiment of the present invention.

  • the excavator dragline rope to include 9, 10, 1 1 , 12, 13, 14, 15, 16 or more outer strands around the IWRC.
  • the use of 9 or more outer strands on a dragline rope capable of withstanding the forces a dragline rope experiences provides a higher strength than if the conventional 6 or 8 outer stand dragline ropes were used.
  • the strands of the dragline rope of the present invention are made from steel or an alternative material as understood by the skilled addressee.
  • the IRWC prefferably includes from between 4 and 18 core strands, not just the six core strands 17 as illustrated Figure 1 .
  • the IWRC 20 is plasticated around the core strands 17 and the WMC 18 to form a plastic covering 29 that defines the shape of the IWRC 20 around which the outer strands 13 are wound. Between the outer surface of the IWRC 20 and adjacent outer stands 13, wormings 15 are laid along the length of the dragline rope 1 1 to offer additional support and cushioning between the outer strands 13 and the IWRC 20. [0031 ] In one embodiment the wormings are made of the same metal material of that the outer strands 13, core strands 17 and WMC 18 are made from.
  • the wormings include aramid fibres or other synthetic fibres as understood by the skilled addressee suitable to strengthen the dragline rope.
