Rope: A rope is an article of cordage, more than approximately 4mm in diameter, obtained when: Three or more strands are laid or plaited together. A core is covered by a braided or plastic film Sheath. TYPES OF ROPES ARE:

• Cable Laid Rope: A rope formed by three or more ropes twisted to form a helix around the same central axis. The ropes that become the secondary strands are “S” lay and the finished cable is “Z” lay or vice versa.

• Combined Rope: A rope in which the strand centres are made of steel and in which the outer portions of each strand are made from the fibrous material.

• Double Braided Rope: A rope in which a number of strands are plaited to form a core and around which are plaited further strands to form a sheath. The core lies coaxially within the sheath.

• 8 Strand Plaited Rope: A rope normally composed of 4 pairs of strands plaited in a double 4-strand round sennit.

• Hard Laid Rope: A rope in which the length of lay of the strands or the rope is shorter than the usual, resulting in a stiffer & less flexible rope.
• Hawser Laid Rope: A rope of three strands which are twisted to form helixes around the same central axis.
• Laid Rope: A rope in which 3 or more strands are twisted to form helixes around the same central axis.
• Shroud Laid Rope: A 4-strand rope with or without a core with the strands twisted to form a helix around the central axis.
• Soft Laid Rope: A rope in which the length of lay of the strands and/or the rope is longer than usual resulting in a more flexible rope which is easily deformed.
• Spring Lay Rope: A rope made with 6 strands over the main core, each strand of which has alternative wire and fiber components laid over a fiber core.
