EOT Crane TCO Calculator Guide
Quick Answer
The cheapest EOT crane quote is not always the lowest-cost crane. Compare total ownership cost by adding normalized capex, expected downtime cost, annual maintenance, critical spares, service life, and hidden scope costs.
A TCO comparison helps procurement explain why a technically stronger quote may be cheaper over five years than a low capex quote with weak service or poor components.
TCO Inputs to Compare
| Input | Why It Matters |
|---|---|
| Normalized capex | Include crane, freight, erection, commissioning, testing, and documentation. |
| Downtime hours per year | Weak components and poor service can stop production. |
| Downtime cost per hour | Even a rough estimate changes the buying decision. |
| Annual maintenance cost | Planned and expected corrective maintenance should be compared. |
| Critical spare starter cost | Initial spares reduce downtime risk. |
| Expected service life | Use the same comparison horizon for all vendors. |
Simple Five-Year TCO Formula
Estimated 5-year ownership cost = normalized capex + 5-year downtime cost + 5-year maintenance cost + initial critical spares.
