Wire rope inspection is mostly carried out when there are major problems with the wiring system of the plant. It mainly occurs when there is a loss in voltage level and a major breakdown in the electrical system. This may result in short circuits, overload and voltage loss in other components connected with the plant. As such, they carry out the required task in a quick manner and try to rectify the situation. So there is a need to know what wire rope inspection is all about and some of the techniques used to carry it out.
Basic guidelines to follow when performing Wire rope inspection
There are various guidelines for this kind of inspection. One of them is to inspect wire rope slings or bundles of cables carrying electricity in power distribution systems.
Identifying Voltage and current
You need to be familiar with the guidelines of voltage and current identification. The guidelines include the identification of the voltage level to avoid any kind of breakage or short circuit in different components.
Identifying Length of wire
These guidelines tell us that the length of wire should be checked. If the wire has more than 100 ft., it should be inspected on the outside. The length of the wire should be properly judged based on its diameter.
Verifying the wire
The next thing that should be done is to verify if the wire has any coating or insulation around it. The wire should be inspected carefully by looking at both ends of it. The inspectors usually check for corrosion on both the sides of the wire as it is an indication of problems in other parts of the wire drum.
Identifying lubrication level
The inspectors are also required to check whether there is sufficient lubrication present in the wire or not. This is essential because without lubrication the wire will get damaged easily when it is working under extreme heat, pressure or friction. The metal that lies on the surface of the wires tends to get corroded.
Another important thing to check is the amount of wear and tear. This can help them find the best way to repair a wire.
Identifying the present condition of sheath
The inspector should inspect the entire length of the wire to know about the condition of its sheath and wrapping. If the sling is not maintained well, the performance will be affected. The sheath is made of several layers of coating and the entire length of the strands gets influenced by its condition.
Checking entire length
The inspectors should inspect the entire length of the rope for any crack or tear in its wrapping. This will help them determine whether the cranes are suitable for crushing or not. Crushing should be avoided at all costs because the performance of the drum will be affected badly.
Knowing wire diameter
It is necessary to know about the wire diameter and the wire length before the inspection. The diameter refers to the diameter of the opening while the length plays an important role in identifying whether the inspection is being conducted properly.
The process of wire rope inspection
1) Ground should be prepared
Before the inspection, the inspector should prepare the platform for carrying out the inspection. It is important to prepare the ground for walking around on. The actual inspection should start after the ground is prepared. The platform should be supported by a tripod.
2) Marking the locations
The next step involves walking around the area and identifying the points. The inspector should mark the locations where the broken wires are present. The same procedure should be followed for identifying the locations where the sharp ends are found. When all the locations are marked, the next step should be carried out. This involves walking around the area and applying pressure over the sheaves to check whether they are operating properly or not.
3) Placing drum for storage
When the wire rope inspection has been completed, the technicians should place the drum in a suitable location for storage. The maintenance program should also be stored in a safe place when the drum is not in use.
There are many advantages of the wire rope inspection. The inspection will identify the issues like the breaking of cables and the presence of the sharp ends. In addition, the inspection will help in determining the type of loads that are applied on the drum. The inspection also helps in determining whether the machine is suitable for crushing or not.
