How to determine the correct rope lay direction?
First step: Check how the rope runs from the drum into the reeving.
There are two possibilities:
– overwound drum (fig. 31 and 33)
– underwound drum (fig. 32 and 34)
Second step: Put your hand on the rope on the drum
– Index finger shows in the direction of the rope running into the reeving
– Thumb shows to the rope fix point on the drum
Third step: Decision
– If you need your left hand to fulfill the requirements of the second
step, then you need a left-hand rope (fig. 31 and 32).
– If you need your right hand to fulfill the requirements of the second
step, then you need a right-hand rope (fig. 33 and 34)
