Loops
Perform testing as follows:
■
The whole length of the cable must be examined, especially the part that is used the most: to
check for potential wire break, the cable should be bent.
■
Check cable clamps for deformation, crushing, wear, cuts.
■
Examine the cable's attachment point at the clamping plate thoroughly.
■
Check the anchoring hook and safety lever at the end of the cable for deformation, wear, wid-
ened hook opening, cuts and elongation.
■
Winches with plastic rope
The rope is not an antitwist rope, which means that it should always be moved in a figure eight config-
uration. In most cases, the same applies to the steel rope. The jacketing can be used to identify
whether the rope is twisted. The stripes (markings along the length) indicate any twisting in this case.
■
Running the rope through your hands will allow you to see and feel how worn the rope is, and
therefore determine whether it needs to be replaced. If the core of the rope is visible, the rope
must be cut away or, at the very least, the damaged part must be removed.
■
Lateral markings on the rope also indicate whether there is any damage to the core: The dis-
tance between the lateral markings increases as the core tapers off.
■
A rope always tapers off before it tears. This must be taken into consideration. What are
known as corkscrews also indicate that the core is damaged.
IMPORTANT
Always contact a Prinoth technician if you are uncertain about anything.
