The weekly check catches what develops slowly. A bolt does not loosen in a
day, and a wire rope does not fail without warning — but both have time to
become dangerous between two annual inspections.
What belongs here
- Bolted connections — see bolt inspection
- The full accessible length of the wire rope, not just the part you see daily
- Lubrication points and oil levels — see lubrication
- Wearing parts: sheaves, drums, rope guides, brake linings
- Structure: welds, cracked paint that can hide cracked steel, deformed members
- Leaks — hydraulic, gearbox, engine. Where it drips, something is missing
- Electrical: cable entries, damaged cables, the security of trailing contacts
How often is “weekly”?
The interval is in the manual for your crane, and it may be shorter than a
week under intensive use, in a coastal climate or in dusty conditions. Running
hours and operating conditions govern — not the calendar alone.
Write it down
A weekly check that is not documented has, in practice, not happened. It is
also what you have to point to if something goes wrong later.
No thresholds here — by design. Discard criteria, torque values, lubricant types and intervals are specific to your machine and your equipment. They are in the manufacturer's documentation, on the equipment certificate, and in the report from sakkyndig kontroll. This page tells you what to look at and what a fault looks like — it does not tell you when something is condemned. If a check leaves you unsure, the equipment stays out of use until someone competent has seen it.
