4.4 Checking the hoisting ropes
WARNING
Crane operation with defective hoisting ropes
Worn-out or defective hoisting ropes may rip or break. The load may
fall. This may result in accidents involving material damage or personal
injuries.
1. Operating the crane with worn-out or defective hoisting ropes is pro‐
hibited.
WARNING
Maintenance work without adequate safety precautions!
There is an increased risk of falling when carrying out maintenance
work from an elevated place without adequate safety precautions. This
may cause injuries, which could even be lethal sometimes.
1. The personnel must be protected with suitable aids (e.g. platform,
railing) when carrying out maintenance work on the mobile crane.
Use the existing access steps and ladders.
Check the condition of hoisting ropes regularly.
These checks must be conducted by experts. Prevailing national regulations and guidelines must
be observed.
Please contact your TADANO After-sales Service in case of queries or problems. It will gladly carry
out all the servicing, maintenance and repair work that crops up.
Rope drives of mobile cranes are not designed as high fatigue-resistant. Therefore, ropes may
break during operation. Principles for monitoring the rope drives during operation are specified in
DIN 15020 T2 and ISO 4309.
Check the hoisting ropes regularly by taking into account the existing operating conditions of the
mobile crane. The hoisting rope must be checked thoroughly at short intervals especially during the
initial period after fixing it, after replacing it as well as in case of exceptional loads or possible dam‐
age that cannot be detected from outside.
The operational safety of the hoisting ropes being used can be evaluated as per the following crite‐
ria:
▪ Type and number of wire breaks
▪ Position and chronological order of wire breaks
▪ Change in the rope diameter during the operation period
▪ Corrosion
▪ Wear
▪ Rope deformations
▪ Heat effects and
▪ Service life.
