Wire rope inspection

Evaluation data taken from the more than 8 thousand reports of the laboratory and field wire ropes inspections show that the visual methods and life time criteria are non adequate to real durability of the ropes in service [4]. The data show that only a very small percentage of all ropes was replaced in a proper time, when one has used a visual inspection.

Securing the safety of mining ropes is an important topic. The visual inspection of wire ropes is necessary to prevent a catastrophic failure, as well as determining and extending the safe operational limits of mining ropes. The situation in all mine shaft systems with rope operation is known usually it is necessary to visually check the ropes for external damages on a regular basis. 

There are also detailed inspections, tailored to the activity and equipment involved. In detailed inspection, people look for very specific conditions. For example, a rigging inspector for a crane must have skills to identify about 20 kinds of defects in wire rope. Some defects are easy to recognize. Others are difficult. They require special training and considerable experience. 

Rigging equipment, used for moving materials, is another factor associated with material handling. Every time material is moved, the equipment should be inspected prior to moving. This subpart breaks down the weight of materials that can be moved using a wire rope, which must also be inspected before use. There are several types of ropes that can be used for moving materials... 

Wire rope slings also require regular inspection because the first signs of failure often are not readily noticeable. A rope failure could result in a crippling ii jury or even death. 

Wire rope in cranes and hoists is inspected daily and before use. 1 2 3 4 N/A... 

Rigging apparati used for lifting and material handling, such as hooks, wire rope, and chains, must be visually inspected daily and monthly with a fuU, written, dated, and signed report of the condition and kept in a file and readily available to designated personnel (see Figure 25.2). 

Wire ropes on equipment must not be used until an inspection under this paragraph demonstrates that no corrective action under paragraph (a)(4) of this section is required. 

At least every 12 months, wire ropes in use on equipment must be inspected by a qualified person in accordance with paragraph (a) of this section (shift inspection). 

Option (2). Wire rope must be designed to have, in relation to the equipment s rated capacity, a sufficient minimum breaking force and design factor so that compliance with the applicable inspection provisions in 1926.1413 will be an effective means of preventing sudden rope failure. 

Describe the defects that might be identified in a wire rope sling during routine inspection prior to use. 

Ensure that all wire rope slings are inspected by a competent person for damage each day before use and additionally as conditions warrant. Damaged or defective slings must be immediately removed from service. See 29 CFR 1910.184(d).

In the first mode a LMA value and number of wires broken per a lot of the rope length (definited in a number of the rope diameter) as like as a register of inspection data can be performed by the 4 digit LED display. After the inspection the data can be displayed in turn. 

The INTROS Flaw Detector is able to inspect ropes moving through the magnetic head at speed 0...2 m/s. Limit of sensitivity to wire brake is 1% of the rope meatallic cross-section area, the LMA measure accuracy is not less than 2%. 

The magnetic inductive inspection is usually performed at least once a year and represents a state report of the rope with reference to its expected service life, as the rope slowly fatigues due to the bending cycles during operation and single wires break. Local accumulation of broken wires can make it necessary to remove the rope.
