THE chairlift at Patriata (Murree) was installed decades ago. It has been providing fun to the tourists.
I wonder if the chairlift is being inspected and tested periodicallyforits load. A typical load test comprises loading the uphill chairs with bags of water, secured in boxes, weighing more than the worst case passenger loading scenario.
Is the system`s ability to start, stop, and forestall reverse operation being carefully evaluated against the system`s design parameters? The rope is the main item in a chairlift system. Is a frequent visual inspection of the rope being carried out besides undertaking periodic nondestructive testing? Electromagnetic induction testing detects a broken wire,corrosion, wear and tear, etc. Is the rope being regularly lubricated to protect it from corrosion thus ensuring safe operation? The maintenance may require stopping the chairlift operation for a few days which is worth it and should be agreed to by the management. This is necessary for the safety of human lives involved.
