Steel Wire Rope

Lam Hong carries a minimum stock of 2,000 Ton of wire rope.

Construction of Steel Wire Rope

The design of a rope is determined by:

  • STRAND CONSTRUCTION - The number and arrangement of wires in each strand
  • ROPE CONSTRUCTION - The number and arrangement of strands in each rope
  • THE CORE
Wire Rope Lays
Right Lay Clockwise
Left Lay Counter-Clockwise
Regular Lay Wires in strands are laid in the opposite direction of the strands and are parallel to the rope axis.
Lang Lay Wires are laid in the same direction as the strands of the rope, and in an angle to the rope axis.

Longer lengths of the individual wires are exposed, creating greater resistance to wear and improve flexibility.

Lang lay ropes should only be used where both rope ends are "fixed" and therefore, should not be used with an swivel type terminal.
Grade 135 Kg/mm Special grade to meet requirements of hoisting rope on traction elevator.
Grade 150/160 Kg/mm Galvanized wire coated with zinc through hot dip process for protection against corrosion.
Grade 165 Kg/mm Ungalvanized and drawn galvanized wire for wire rope of general purpose.
Grade 180 Kg/mm Extra high tensile grade is used in the manufacture of wire rope for special application where ultimate breaking strength is required.
