A well selected rope is necessary for economical operations and will avoid damage of rope and maschine as well as standstill on site. The fundamental decision for the use of a non-rotating or not-rotation-resistant rope should be made at first.
The following rules should be observed:
- Non-rotating hoisting ropes should always be selected when:
a) unguided loads are to be lifted on single line or
b) unguided loads are to be lifted on multi-part-line reeving systems over great hoisting heights.
Non-rotating rope constructions can work with and without swivel!
- Not-rotation-resistant ropes should always be selected when:
a) guided loads are to be lifted orb) guided loads on multi-part-line reeving systems are to be lifted over short hoisting heights or
c) unguided loads are lifted on paired systems with right- and left-hand-lay ropes
Not-rotation-resistant ropes must never be used with swivel!
