How to use this tool
Build a schedule before small crane defects become stoppages
This page is for plant maintenance engineers, safety teams and production managers who need a practical starting point for routine EOT crane inspection. It turns basic operating conditions into a visible maintenance checklist that can be printed, reviewed and adapted to your site procedure.
Purpose
Use the generator to create a preliminary daily, weekly, monthly, quarterly and annual maintenance route. The goal is not to certify the crane. The goal is to make recurring checks visible so rope, brake, wheel, control and runway issues are not missed until failure.
Inputs Explained
- Crane type: changes the systems your team should pay attention to.
- SWL: higher-capacity cranes deserve closer structural and wheel-load attention.
- Use pattern and hours: heavier duty usually means shorter inspection intervals.
- Environment: dust, heat, humidity and outdoor exposure increase wear and electrical risk.
- Criticality: production-critical cranes need better spares and faster defect closure.
Schedule Basis
The generated schedule uses practical maintenance grouping: pre-use checks, routine cleaning and functional checks, documented monthly inspection, deeper quarterly review and annual competent inspection planning. It intentionally separates operator observations from maintenance records and major review items.
Formula Basis
This is a rule-based planner rather than a numerical design formula. The tool increases maintenance attention when duty, daily operating hours, environment, SWL and production criticality indicate higher wear or downtime risk.
Assumptions
- The crane is already installed and in service.
- Manufacturer manuals and site safety rules remain the controlling references.
- Any unsafe observation should be escalated immediately instead of waiting for the next interval.
- Inspection frequency should increase when duty, operating hours or environment becomes severe.
How to Interpret Results
Treat the output as a starting maintenance route. Add your crane ID, exact make/model, local regulatory requirements, lockout procedure, spare-part list and responsible person. If the same fault repeats, move from checklist completion to root-cause correction.
Worked Example
For a 10 t indoor production crane running about 8 hours per day with high production criticality, the generated plan adds closer weekly and monthly attention to brakes, wire rope, wheels, controls, recurring faults and critical spare availability.
Limitations
This tool does not determine legal inspection intervals, issue a fitness certificate, approve load testing or override OEM instructions. Final inspection, repair, testing and return-to-service decisions must be made by competent people using applicable rules and site procedures.
