A RopeQ inspection lets you know when a wire is at the end of its tether, even when there are no visible signs of fatigue.
In hoisting applications, one of the most critical elements for safety is the durability of wire ropes. As corrosion, tension and abrasion wear away at the wires and core of the rope, its working life is inevitably finite. Regular inspection to detect breaks and fatigue can detect a timely replacement before dangerous situations occur.
Optimizing the right change intervals for ropes can be difficult, as some types of damage are difficult to observe with the naked eye.
“Rotation-resistant ropes, for example, are keen to suffer from internal wire breaks that are left unseen with visual-only inspections,” says Saku Aspelin, Product Manager, Consultation Services at Konecranes.
SHOWING YOU THE ROPES
In other cases, internal corrosion is a major problem. For instance, the boom ropes of a ship-to-shore crane are exposed to the elements and are stationary for long periods of time. With time, rain water slowly penetrates the rope and corrodes it from the inside. Lubrication added to protect the rope’s surface can lock the water in, contributing to the damage.
To detect non-visible defects such as these, Konecranes uses a special inspection method called RopeQ. A RopeQ inspection combines a regular visual check with magnetic-inductive leakage technology, providing accurate data on the integrity of the rope’s interior. This way, the outside and inside of the wire rope can be inspected in a non-destructive manner.
