The value of a fault log
A fault recurring usually means the symptom was treated, not the root cause. For example, replacing a worn wheel postpones the fault for a few months; unless the runway is measured, it comes back from the same spot.
If every intervention records the date, symptom, work done and part replaced, a repeating pattern becomes visible after a few entries. This log also helps during periodic inspection and warranty discussions.
Frequently asked questions
Can I fix the fault myself?
Simple checks (battery replacement, emergency stop, visual inspection) can be done by operating staff. Brake adjustment, the electrical panel, rope replacement and limiter calibration are jobs for qualified personnel; a wrong intervention is both dangerous and voids warranty.
What information should I have ready when calling for service?
The crane's nameplate data (capacity, serial number, year built), the symptom, how long it's been happening, any VFD fault code, and the last maintenance date. This gets the right part to site on the first visit.
The crane runs but makes a noise — can it wait?
A new noise is always a sign something has changed. Noises from the brake, gearbox or wheels turn a small maintenance item into a major failure if ignored.
