Steel Wire Rope
Wire Rope 6 x WS(36) IWRC Galv.
Wire Rope 6 x WS(36) IWRC Galv. is a group of 25 IMPA-coded items (codes 213151–213175) under Steel Wire Rope in the Rope & Hawsers section (IMPA 21). All of them are priced per coil. Every item in the list is galvanised. The list runs through 25 metric sizes from 20 mm to 50 mm. Each item is listed as supplied with a test certificate.
Buying guide
Wire rope 6xWS(36) IWRC is a six-strand rope with 36 wires per strand in Warrington-Seale lay around an independent wire rope core. The IMPA lines in this group are galvanised, sized by diameter in millimetres, sold by the 200 m reel and supplied with a certificate. On board it serves as crane and davit falls, cargo runners, topping lifts and winch wires.
The requisition is raised by the chief officer for deck cranes and cargo gear, or by the chief engineer for engine-room hoists. Because the rope is part of lifting equipment, it comes under the ship’s examination and certification regime as well as the crane maker’s rope specification.[1]
How to specify it
State diameter, construction (6xWS(36)), core (IWRC), finish (galvanised), rope grade, lay direction, minimum breaking force, length, and any end terminations. EN 12385-4 is the European standard for stranded ropes in general lifting service; it tabulates minimum breaking force by rope class, size and grade, so quoting the standard and grade lets suppliers offer like for like.[2]
Copy the crane or winch maker’s rope specification rather than matching an old reel by eye, and ask for the certificate to travel with the reel: the ship needs it on board for the lifting equipment records.[1]
Rules and certificates
ISO 4309 sets the principles for care, maintenance, inspection and discard of steel wire ropes on cranes and hoists, deck cranes included. It gives discard criteria for multi-layer spooling at drum crossover zones, for decrease in diameter and corrosion, and a method for assessing combined deterioration at any point in the rope.[3]
Under the UK lifting equipment regulations, lifting equipment exposed to deteriorating conditions is thoroughly examined at least every 12 months (every 6 months for accessories and equipment for lifting persons) or under an examination scheme, and a certificate is held for each test and thorough examination.[1]
The Code of Safe Working Practices asks for wires to be lubricated regularly, inspected internally and externally for broken strands and never allowed to dry out. Eyes should be formed by splicing or swaged ferrules; bulldog grips should not be used on lifting or mooring wires.[4]
Questions buyers ask
- Which standard covers the breaking force of this rope?
- For general lifting service in Europe, EN 12385-4 tabulates minimum breaking force by rope class, size and grade. Quote the grade with the diameter so offers are comparable.
- When is a crane wire discarded?
- Against the criteria in ISO 4309 and the crane maker’s instructions — broken wires, loss of diameter, corrosion and their combined effect, with particular attention to drum crossover zones on multi-layer spooling.
