New, Used, or Rental: A Cost Controller's Sandvik Drill Rig Guide

Before you buy a Sandvik drill rig or a mobile crushing plant, answer one question first: what happens if that machine sits idle for a month? If the thought doesn't bother you, you might not need to own it. You might need to rent it.

I know 'it depends' is an unsatisfying opening. But after seven years as a procurement manager at a mid-sized aggregates and civil construction company, I've approved—and blocked—enough equipment purchases to know that the right answer depends on your operating scenario, not on a glossy brochure.

The framework below is the same one I use in budget reviews. Let me walk you through it.

Three scenarios, not one universal recommendation

In my spreadsheets, most equipment decisions fall into three groups:

Scenario 1: High utilization and a long site life. New equipment can be the lowest total cost option, despite the highest purchase price.

Scenario 2: Moderate utilization and a two-to-five-year horizon. Dealer-certified used equipment usually offers the best balance of capital cost and reliability.

Scenario 3: Short, intermittent or unproven work. Rental, contract drilling, or contract crushing often makes more sense than owning.

Now let's get into each one.

Scenario 1: High utilization and a long site life — new is often the cheapest option

If a machine will run twelve to sixteen hours a day, five or six days a week, for more than five years, the purchase price is only the beginning. Your real metric is cost per tonne or cost per meter drilled.

Downtime is the hidden killer. Suppose your crushing plant does 600 tonnes per hour and your contribution margin is $9 per tonne. A single lost 10-hour shift is roughly $54,000. Once you put numbers like those into a total cost of ownership model, the difference between new and used starts to shrink. Sometimes it disappears.

New equipment matters most when three things are true: the load is heavy, the schedule is unforgiving, and you cannot afford to play babysitter. That is when a factory warranty, predictable maintenance intervals, and responsive dealer support become measurable financial benefits.

Does that mean every new machine is justified? No. But in this specific scenario, choosing the cheapest machine is usually a false economy.

Scenario 2: Moderate utilization and a two-to-five-year horizon — certified used can be smart

If you don't have five or more years of production ahead of you, a new machine is hard to defend. The capital cost doesn't have enough operating hours to spread out. This is where a used machine can win, but only if you buy it with evidence rather than enthusiasm.

My first choice is dealer-certified used equipment. I have learned that 'looks good' and 'is good' are two different things. In 2020, I bought a mobile screen at auction for roughly 40% below dealer pricing. The paint was original, the hour meter was low, and the first two weeks were fine. Then the main conveyor drive failed, followed by hydraulic problems. By the end of the season, I had spent $41,000 on repairs that a documented service history would have helped me avoid.

When I evaluate used equipment now, I ask for service records, maintenance intervals, and an independent condition assessment. If the seller hesitates, I walk. That sounds cautious, but a $41,000 mistake changes your perspective.

Scenario 3: Short or uncertain projects — rent or hire the capacity

This is the scenario that many companies overlook. They hate the idea of paying a rental rate when they could be building equity. I have mixed feelings about rental premiums. On one hand, they can feel painfully high. On the other hand, depreciation is even more painful when a machine sits idle for weeks.

If the project is shorter than about twelve months, or the reserves are not proven yet, owning a specialized machine is a gamble. Renting gives you a known monthly cost and no residual value risk. You can also hire a contract drilling or crushing crew; their cost per tonne includes the risk on their side, not yours.

The trick is reading the fine print. Ask about mobilization, demobilization, standby time, weather delays, and overtime. Rental invoices like to hide costs in those line items. (I learned to check standby clauses after a wet spring cost us more than the rental rate itself.)

How to tell which scenario you're in

If you are not sure, don't rely on gut feel. Ask four questions:

• What utilization can we honestly forecast? Above 70 to 80 percent of available days points to Scenario 1. Forty to seventy percent points to Scenario 2. Below forty percent points to Scenario 3.
• How long is the need? Five plus years argues for new. Two to five years argues for certified used. Less than two years argues for rental or contract services.
• Can we support the machine? If you don't have operators, maintenance staff, or a reliable parts pipeline, rental or contracting becomes more attractive even at a higher unit cost.
• What else could this capital do? Every dollar tied up in a machine is a dollar not spent on other reserves, upgrades, or permits. Capital drag is a real scenario.

If the scenario is still unclear, run a total cost of ownership model for all three options over seven years. Compare them at year three and at year seven. In my experience, the crossover shows up clearly once the cash flows are in the same spreadsheet.

The hidden cost that changes the answer

The largest hidden cost in equipment decisions is not fuel, financing, or even maintenance. It is unplanned downtime.

When I present a capital case to our finance team, I include downtime as lost contribution margin. If a machine processes 600 tonnes per hour and your contribution margin is $9 per tonne, an unplanned week works out to roughly $270,000 of lost contribution. That number is larger than most repair invoices. That is why I don't automatically choose the lower-priced option. I choose the option with the highest probability of being available.

Before you finalize any purchase request, ask your supplier for a written maintenance and support plan. Ask about parts availability, response time, and operator training. A good answer will not justify an unnecessary purchase, but it tells you who is responsible when something goes wrong.

Why I read Sandvik rock processing news before I sign anything

I am not a brand advocate. I am a buyer who wants to avoid owning technology that becomes outdated in three years. That is why I read official manufacturer updates before writing a capital request.

If you read Sandvik rock processing news, the recurring themes are automation, remote monitoring, and serviceability. Those topics matter because they change operating cost, not because they sound impressive. If a machine can be set and monitored consistently, three different operators are more likely to produce consistent results. That consistency shows up in the cost-per-tonne report.

Sandvik's official website is also where I verify current specifications and product line changes. Configurations and prices vary by region and by date, so confirm what you are actually pricing before you submit the request.

The bottom line

New. Used. Rental. There is no moral high ground. I have bought new machines that made sense, used machines that made sense, and rented machines that made sense. I have also made mistakes in every category.

A machine that is working for you is an asset. A machine that is waiting for work is a liability. Make sure you know which one you are buying.

An informed customer asks better questions. Run your own utilization numbers, build your own total cost model, and then make the call with confidence.
