Prioritise brakes, contactors, limits, controls, wheels, bearings, rope/chain and drive parts by failure impact, lead time and replacement difficulty rather than price alone.
What makes a spare part critical?
Criticality is not the same as price. Consider whether its failure stops production, whether a temporary alternative exists, lead time and the access needed for replacement.
- Production impact
- Lead time
- Alternative availability
- Replacement access
Separate fast-moving from long-lead items
Contactors, fuses, buttons or some limit devices may be fast-moving, while special brakes, wheels, gearboxes, motors or rope components may have longer lead times. Keep inventory by equipment make, model and technical dimensions.
- Fast-moving group
- Long-lead group
- Make/model matching
- Dimensions and part number
How is stock level defined?
Number of identical assets, annual fault/replacement history, shifts and planned shutdown windows influence stock level. Common parts across multiple cranes can be consolidated into a central critical-spares list.
- Asset count
- Failure history
- Shift intensity
- Planned shutdowns
How to reduce ordering errors
Keep nameplates, part numbers, shaft/hole dimensions, electrical ratings, connection type and clear photographs in one technical record before ordering. The same record reduces identification time during breakdowns.
- Nameplate and part number
- Measured photos
- Electrical ratings
- Connection type
