Why do I need opposite lay in my winding ropes on a multi-rope system?
Even when recommending ‘non-rotating, rotation resistant ‘ constructions i.e. FLC, Multistrand, all ropes have a tendency to twist when a load is applied. So to further reduce the affects of rope torque when loaded it is advisable to have a left and right hand laid rope in the winding system.
In a four rope hoist application the ropes should be installed left hand lay, then right hand and left then right hand lay again, not two left and then two right.
