wire rope failure analysis pricelist
Due to the wide variety of service conditions for wire ropes, they are susceptible to many types of inadequacies and failures. It is important for consumers to frequently inspect wire ropes for signs of wear and fatigue. Wire ropes will inevitably fail if not used according to manufacturing limitations or when routine inspections for fatigue and wear are not properly performed. Eventually, all wire ropes are removed from service when they meet established discard criteria.

Unfortunately, many phone calls into ITI Field Services begins this way, “We have had an incident with a wire rope and we believe the rope failed. How do we determine the cause of failure?”
Fortunately, the calls come in because wire rope users want to determine cause of failure in an effort to improve their crane, rigging and lifting activities.
A wire rope distributor received a hoist rope and sockets from a rubber-tired gantry. The rope and sockets were returned by the customer who believed the rope and sockets failed. The distributor hired ITI Field Services to conduct an analysis on the rope and sockets to determine the cause of the failure and to produce written documentation.
Based on the findings of the examination, fatigue-type breaks in the wires indicated that the wire rope lost significant strength due to vibration. There was no indication that the rope was overloaded. The poured sockets showed no evidence of abnormalities in the pouring method, wire zinc bonding length or the materials used in the speltering process. The conclusion of the inspection is that rope failed due to fatigue.
Wire rope examination is just one of the many services that is offered by ITI Field Services. ITI has some of the most highly-regarded subject-matter experts in the crane and rigging industry with experience in performance evaluations, litigation, accident investigations, manual development and critical lift planning reviews.
The CSIR is the recognised custodian of in-service mine rope technology, and performs the bulk of the statutory tests required for hoist ropes in the mining industry.As a National Key Point, the Wire Rope Testing Laboratory also maintains the largest historical database of rope tests in Africa.
Access to rope test data and certificates are provided via a user-friendly web-based system. Through this facility clients can get direct access to their test results, and the Department of Minerals and Energy can draw lists of tests performed by the various mines. Registered users can follow the link below to access the rope test database. (Rope Certificates) The rope test prices are also provided.
Safety is a crucial factor in the profitability of the mining industry. With thousands of workers transported up and down mine shafts each day, measuring the safety of hoisting ropes form an integral part of mine management.Strict laws cover the maintenance and testing of steel wire ropes.The Wire Rope Testing Laboratory focuses mainly on the destructive testing of these ropes.
For each hoist rope tested, the customer is provided with a detailed report that includes the breaking force, absorbed strain energy, force vs. elongation curve and an assessment of the condition of individual strands and wires at the point of failure.The report also alerts the customer to rope characteristics that breach, or are approaching, accepted performance standards. For example, a breaking force that is 90% or less than the new rope-breaking force. An assessment of corrosion and general rope lubrication is also provided.
The Laboratory is an advanced technology facility housing state of the art wire rope testing equipment.The machines used in the destructive testing of steel wire ropes have capacities ranging from 1 MN for small diameter ropes, to 15 MN for ropes up to 160 mm in diameter.
A 15 MN MFL tensile test machine which is able to accommodate large-diameter ropes as used in the oil drilling, bridge and shipping industries.It also caters for tensile tests on conveyor belts up to 1.2m wide and large-link chains as used on coal mine draglines and;
The CSIR Wire Rope Testing Laboratory is the government approved facility for statuary testing of winding ropes. Because of the CSIRs impartiality, professionalism and technical expertise, rope manufacturers locally and abroad also choose to have their wire rope samples tested by the CSIR. Existing clients include, but are not limited to, the following:
Wire rope isa type of cablewhich is made up of several strands of metal wirelaid or twisted into a braid or helix.Do you know how often your wire rope needs to be inspected? Wire rope inspections are vital to industries that use wire rope.
One of the most important purposes of carrying out wire rope inspections or testing is to oversee the process of depreciation in the wire rope. When any depreciation or deterioration is identified these wire ropes can cease to be used immediatelybefore it becomes a hazard. A great advantage of conducting these examinations is to analyse and identify if there is unexpected corrosion and destruction.
Commonly, there is a constant increase rate in the amount of wire rope breaks, during the lifespan of that wire rope. Wire ropes need to be inspected and tested as they have a limited life, like all consumable products. Early in the life of the wire rope (when it is starting to be used), the wires and strands of the rope settle into position and the breaking strength increases. Once it has hit its maximum, the breaking strength then decreases rapidly.
Wire rope inspections should only be carried out by highly trained professionals. There are 2 ways that these inspections are carried out on crane wire rope: Visual and Non-Destructive. Visual and no-destructive examinations are equally as important but a non-destructive wire rope test is a lot less frequent than a visual wire rope inspection. Destructive testing only takes place when specifically required by a company to find out what type of wire rope something is that has not been labelled and is not common practice in the general testing/inspections.
Visual inspection of wire ropeThe visual method is a simple yet effective method to check for external damage to a crane wire rope. Visually inspecting the entire length of rope is very important. The rope should be inspected 2 to 3 feet at a time and examined carefully at each stop. Whilst inspecting the wire rope it also cleaned with Lanotec and a wire brush.
Although tedious, it can determine many visual signs of wire rope damage, such as; kinks, bird caging, cutting, knots, flattening, crushing & heat damage (burn marks, discolouration of the metal). Wearing heavy duty gloves, an inspector will grab the rope and lightly move a rag slowly along the length of rope. Broken wires will often stick out (porcupine) and will therefore snag on the rag. Should the rag snag on a wire, the inspector should the stop and visually assess the rope condition. Broken wires do not always ‘porcupine’. Visual inspections should not be the only method relied on for inspecting crane wire ropes.
Due to the composition of a wire rope, the outer layer only represents approximately 40% of the metallic cross section of the rope and only approximately half of this is visible due to the strand twisting inside and out. That means you are only able to visually examine approximately 20% of the entire rope composition. You can only assume that the other 80% is in good condition.
Although the external 20% may look in good condition it may be concealing a great number of wire breaks and internal damage. Wire ropes with internal damage that have no signs of external damage can be extremely dangerous. This is why an internal wire rope inspection should also be completed. Internal deterioration is the primary cause of many rope failures, mainly due to corrosion and the normal progress of fatigue. Single-layer stranded ropes may be opened up slightly to allow an assessment of their internal condition, provided that they are at zero tension; though, some restrictions occur with large rope sizes. Permanent damage can be caused to multi-layer wire ropes if they are opened.
Internal inspection should always be carried out by a capable person. The method of inspection consists of firmly attaching two clamping jaws of appropriate size at a suitable distance apart to the rope. During the inspection of sections of rope adjacent to terminations, it is adequate to use a single clamping jaw, since the end anchorage system, or a bar suitably located through the end portion of the termination, may be used as the second clamp.
By the application of a force to the clamping jaws in the opposite direction to the rope lay, the outer strands separate and move away from the core. Care should be taken during the opening process to ensure that the clamping jaws do not slip about the outside of the rope. The strands should not be displaced excessively. When a limited opening is achieved, a small probe, such as a screwdriver, may be used to remove grease or debris that could obstruct observation of the interior of the rope. The crucial points that should be observed are as follows:
After inspection, a service dressing should be introduced into the opened part and the clamping jaws rotated with moderate force to ensure correct replacement of the strands around the core. After removal of the jaws, the outer surface of the rope should be greased. Since it is impossible to inspect the interior of the wire rope over the whole of its length, suitable sections shall be selected.
For wire ropes that wind onto a drum, or pass over pulleys or rollers, it is recommended that the lengths that engage the pulley grooves when the appliance is in a loaded condition be inspected. Those localised lengths in which shock forces are arrested (i.e., adjacent to drum and jib head pulleys) and those lengths that are particularly exposed to the weather for long periods should be inspected. Attention should be given to the length of rope close to its termination, and this is particularly important for fixed ropes, such as stays or pendants. This is where a visual inspection is complimented by a non-destructive test. .

When selecting a wire rope lubricant, considerationshould be given to the type of work performed by the rope.The lubricant should not t"Onlaill aCids or other iU!,redieutsthat might corrode the Sled.

A general rule for selecting II wire rope lubricnnt is thatthe highe r the speed at which the rope operatcs, thelighter the lubricant, or, technically speaking, the lowerthe viscosity of the lubricant. For low speed installations, such as shovels, cratlcs, andderricks, a heavy pctroleum oil or grefllSC with viscosity ofapproximately 1000 seconds at 210" Ie. applied hot willgive good lubrication. This same lubricant will also give satisfactory lubrica-tion to stationary fOpCS. Either an oil or grease can beused for stationary ropes provided it adheres to the ropeundcr aU conditions. For heavy haulage installations, such as slofJC ropes andlogging ropes, a lighter lubricant with a vi&."osity of from500 to 800 seconds at 210" .F . should be used. leor high speed hoisting ropes, such as mine hoists aneven lightcr lubricant is recommendcd. One with avistosily of 400 to 500 seconds at 100° Ie. givcs goodservice when automatic lubrication is employed. J n all cases, viscosity should be such that the lubricantwill cover the rope lind penetrate thoroughly, and with-stand pressures, but not be thin enough to run off the rope.

Trans tnis sion or Haulage Rope "Transmission" and "Haulage" are terms that areapplied to rope composed of six strands-seven wires tothe strand. The demand for rope of this construction fortransmission of power has lessened appreciably in recentyears. The principal use to which it is now put is forhaulage in mines, on inclined planes, on tramways and inthe yards of manufacturing plants. It is also used for drill-ing and Sand Lines in certain districts by well drillingcontractors. By comparing the cut, page 15, with the Hoisting Ropecut on page 20 you will note the coarseness of wires. Theyare nearly twice as large. This is a desirable feature, as inhaulage work for which service it is particularly applicable,it is dragged along the ground and over rough rollers, etc.,being subjected to much abrasive wear. Finer wires wouldwear through and break much more quickly. While the coarseness of the wires is an asset so far asabrasion is concerned, the rope is less flexible than one ofthe Hoisting Rope designs. This should be taken intoconsideration if tile rope is to be subjected to much bend-ing. For bending, where greater flexibility is required,ropes composed of finer wires are usually preferred. Made in five grades, or strengths, as follows:
