The crane is an LTM1400-7.1. All LIEBHERR cranes have very detailed reeving plans in the Operators Manuals. There should never be any guess work involved because you should never deviate from the reeving plans, ever.

There is no such thing as a European spec drum or a US spec drum. If anything the drum was flawed during manufacture.

most euro and japanese machines have lagging that is machined to work best with metric sized wire rope. american machines historically have had lagging that was set up for imperial measurements, (5/8,3/4,7/8,1,etc) each works best when used with what it was designed for, although metric sizing has become more prevalent. (all started years back with tower cranes from europe with their high-performance, compacted strand rope).

What I should have said in reference to the "drum" being Euro or US spec was that LIEBHERR (or any of the European machines) would not deviate from their metric specifications to pacify us in America. If a rental company uses a rope that is fractional in size to replace an O.E. rope then they will have to deal with it. In my experience if the rope is winding with gaps between wraps it sometimes is the end where the lagging kicks the rope over, that area could have a dimensional mistake from its manufacture.
