What do your breaker parts really cost you a year?
Compare the part you use now with an ASI part. You enter your own hours, life and price. ASI's life figures come from customer reports and are shown below. It takes about a minute.
How the estimate is worked out
- Changes per year = running hours per month × 12 ÷ part life in hours. For pins, 12 ÷ life in months.
- Cost of one change = part price + fitter cost + (machine hours lost × cost of an idle machine per hour).
- Cost per year = changes per year × cost of one change, worked out for your current part and for ASI.
- ASI price = your price × (1 + the ASI percentage). ASI does not publish prices because steel prices move.
- For chisels, the calculator shows the break-even point: how much longer an ASI 42CrMo4 chisel must last to cost less per running hour.
Example. Through bolt, 200 h a month, 400 h life now against 1,800 h with ASI, price Rs 3,500, fitter Rs 1,500, 4 h lost at Rs 2,500 an hour, ASI 25% dearer: 6 changes a year now against 1.3 with ASI, Rs 90,000 against Rs 21,167, a saving of about Rs 68,833 a year. These example inputs are not ASI data.
| Part | Typical aftermarket life (customer reports) | ASI figure used here | What customers reported |
|---|---|---|---|
| Through bolt (ASI high tensile) | 300–400 h | 1,800 h | 2,000+ h |
| Rock breaker bush | about 500 h | 1,500 h | 1,800+ h |
| Excavator pins and collar bushes | 5–6 months | 15 months | 18–22 months |
| Chisel (ASI 42CrMo4) | Your own figure | Break-even only | Field data being collected |
ASI uses the low end of what customers reported, and raises a figure only when more field data comes in. [placeholder: customer names, once permission is given]
