Is the Skip Overloading or Underloading the Ropes

That is a big skip!!

What ropes? have you any further information?

Hi Electroman,

If our Guest is a Scandinavian then Skip means Ship.

Mind you I cannot realy understand his question, but if he is a Scandinavian then he might as well write in Scandinavian on his post, at least I will be able to understand what he is talking about!

He must have meant 32,000 Kg=32Tonnes. Please all,use the facility of Preview.MM

If I understand the question correctly, it all depends on the difference in the weight and thickness of the skip liners. Find out what the weight of the old liners was from the design information, compare it to the weight of the new liners. Also, is there a diference inteh thickness of the liners? If so, the amount of material going in the skip could have changed. However, withthe size skip you are referring to, I doubt the liner thickness will make much difference. Was this discussed with the company that provided the new liner? To fully answer this question, you need to look at the rope sizing calculations. To do this, you will need to know what size is the rope, what is the maximum length, size of the drum, age of the rope, makeup and material of the rope, etc. The information should be on-hand at the mine site. The calculations can be found in many mining engineering handbooks.

Hello 'Guest',

If possible can you check the difference in weight between rubber and metal liners?

Also, if possible get a tape out and measure the new internal dimension after the metal liners are fitted. From some past dealings talking to friends about compound and steel ropes, the estimated braking point of any rope is at least 50% more than it will be used for. I am not saying not to check, but rope is pretty much over engineered. In particular the newer man-made or compound ropes are amazingly strong.

Good luck..........
