Our ropes must be inspected and discarded using ISO 4309 standard

A steel wire rope is a sensitive flexible safety element. It has to be followed up and regularly inspected by a competent person. The reference document for such inspections is the ISO 4309 standard: cranes - wire ropes - care and maintenance, inspection and discard. The ISO 4309 is a document which cannot be dissociated. It shall be carefully studied and applied.

Some parameters to be monitored when inspecting the ropes

  • Broken wires
  • Decreasing rope diameter (local/general)
  • Fracture of strands
  • Corrosion
  • Wire rope deformations (e.g waviness, baskets, core or strand protrusion or distorsion, wire protrusion, flattened portions of rope, kinks)

Storage, handling and maintenance

The rope must be adequately maintained and regularly lubricated, its surface should always be kept at least slightly greasy. In case of prolonged inactivity or particularly extreme working conditions, a lubricant compatible with the original one must be used and applied with a brush or spray, please contact us for references.
When stored, the rope should be kept in a dry and ventilated environment with no direct contact with the floor and an air flow under the reel. At any time, any contact of the rope with any metallic pieces shall be avoided to prevent early damage.

Specific training

Training courses on wire ropes are available in our Bourg-en-Bresse factory in France or can be organised at your site. Please contact us for further information.

Some ideas to evaluate the condition of a rope

  • A visual inspection is necessary to determine the global condition of the rope
  • A local reduction is the result of a core break: the rope shall be discarded immediately
  • Visual signs: local damages, basket or bird cage, deformations of one or several strands, wire protusion, kinks looped wires, etc.
  • Severe corrosion is a cause for discard

It is important to discard the rope as soon as a discard criteria appears: from this moment the rope deterioration may increase quicker than expected.
