Tadano ATF 130G-5, Translation Of The Original Operating Manual

Page: 481 / 636

Heat effect
Hoisting ropes exposed to an extremely high heat effect can be detected through faded colors of
outer wires. Such hoisting ropes must be replaced.
Service life
If adequate knowledge and operational experience are available for a rope drive, the time for re‐
placing a hoisting rope can be determined for a mobile crane within the scope of a preventive main‐
tenance provided the operating conditions and the hoisting rope remain the same.
The hoisting rope must be checked regularly.
4.4.2 Replacing a hoisting rope
WARNING
Incorrect hoisting rope has been fixed.
An incorrect hoisting rope may rip, break or cause damage to the rope
drive of the mobile crane. The load may fall. This may result in acci‐
dents involving material damage or personal injuries.
1. When laying a new hoisting rope, only use a hoisting rope having
the same strength, the make and the nominal diameter as that of
the original hoisting rope when it was new.
⇨ If other rope type is to be used, a prior written consent of TADANO
is essential.
Utmost care must be taken when unloading, transporting and
storing the hoisting ropes. The hoisting rope must be protect‐
ed against mechanical damage due to fork-lift truck prongs or
lifting hooks when unloading and transporting.
Hoisting ropes stored as reserve must be stored in a clean, cool, dry and covered room such that
they do not come in contact with the ground, e.g. on pallets.
When mounting a new hoisting rope, it must be implicitly en‐
sured that the new hoisting rope is wound up on the winch
without twists and damage. It is most practical to use a rotary
disc or a rack for winding up a hoisting rope delivered in the
ring or on a winch.
When winding from the winch to the drum, it must be ensured
that the same bending direction is maintained for the hoisting
rope.
Rope windings should never be pulled sideways from the ring or the winch since this may lead to
twists in the hoisting rope.
