- A 1.2 m diameter drum winding system is shown. One of the winding ropes will be replaced for the manwinding cage.
Consider the following:
1) A new rope is recapped once at least in every 6 months and a length of 2 m including existing capping is to be cut off from the rope before recapping.
2) The maximum life of a rope is 3.5 years and at least 2 rounds of rope should remain on the drum while the descending cage lands at the bottomost landing point.
3) No overwinding will take place during the maximum life of the new rope.
Neglecting the impact of fleet angle on the length of the rope, the minimum length, in m, of new winding rope is ____.(round off up to 2 decimals)- GATE MN - 2024
