Wire rope inspection & spooling system
Wire rope inspection and spooling system (WRISS)
Extend the life of your crane’s wire ropes with our tensioning and electromagnetic inspection solution.
Investing in new wire ropes can be a costly and time consuming exercise. Our WRISS (Wire Rope Inspection and Spooling System) provides our clients with a service that allows them to confidently extend the life of their ropes and by in-situ condition based inspection.
By using this technique for wire rope inspection, clients gain real information about the condition of their ropes which leads to the potential of their life span being extended and in return reduces replacement costs.
EMAG inspection provides more confidence because:
- The technique allows us to 'see' inside the rope, to detect broken wires and corrosion wherever it occurs.
- The technique provides quantitative data as opposed to a subjective visual inspection.
- Wire ropes being tested do not have to be cleaned first, minimising time.
- We test the ropes and evaluate the results in accordance with standards accepted throughout the world.
- We are able to provide instantaneous results by connecting with a computer while testing is taking place.
- For breaks on the surface, the sensor head will find one broken wire in as many as 250 wires.
- For internal breaks, the detector will find fractures when they amount to 1% or more of the total number of wires.
- For corrosion at any location, the sensor will find 1% or more loss in cross sectional area.
We carry out the inspections on your asset and spool the rope using a tensioner and sheave skid system. By using the tensioner we can ensure the rope is re-spooled at the required tension ensuring consistent and accurate line tension is maintained during the process. Data logging of the re-spooling tension provides evidence that the ropes have been re-spooled onto the crane winch drum at the required percentage of rope minimum braking load (MBL).
The system is cost effective and time efficient as the ropes do not have to be fully unspooled and transported to an onshore location.
Our inspectors are certified ASNT Level II in Magnetic Flux Leakage as well as qualified visual inspectors for wire ropes and slings.
