WIRE ROPE

1.	Construction of 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
2.	Grades of rope wire Young Heung wire ropes are made of steel wires classified into following tensile strength grades to meet various requirements according to the applications. Grade 135 kg/mm2: Special grade to meet requirement of hoisting ropes on traction elevators. Grade 150/160 kg/mm2: Galvanized wires coated with zinc through hot dip process for protection against corrosion Grade 165 kg/mm2: Unglavanized and drawn galvanized wires for general purpose wire ropes Grade 180 kg/mm2: Unglavanized high tensile grade wires for general purpose wire ropes Grade 195 kg/mm2: Extra high tensile grade is used in the manufacture of wire rope where ultimate breaking strength is required

Wire rope lay 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. Ropes with regular lay are easy to handle and have greater resistance to crushing than those with lang lay. 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 improved flexibility. Lang lay ropes should only be used where both rope ends are "fixed" and therefore, should not be used with a swivel type terminal
