Underground mining is brutal on equipment and people alike. When machinery fails down there, it’s not just an inconvenience – it can derail your whole operation and put lives at risk.
We were chatting with a project manager from a mid-sized mine in Northern Ontario last month who got burned pretty badly. They were in a rush to hit some aggressive deadlines and skipped their homework when renting a loader. The thing conked out after just three days during a critical phase. Two weeks of downtime and a $350K hit to their bottom line. Ouch.
The statistics are quite alarming – unplanned equipment failures can be costly for mining companies. With profit margins getting squeezed tighter than a miner in a narrow drift, nobody can afford those kinds of losses these days.
From what we’ve seen at Tim McDowell Equipment over our 50+ years in the business, the mining operations that avoid these disasters usually do one thing right: they ask tough questions before signing on the dotted line. This due diligence stuff isn’t just paperwork – it’s what keeps your crew safe and your project profitable.
Choosing the right underground mining equipment suppliers is a key part of that process. The right partner doesn’t just deliver machines—they deliver reliability, support, and peace of mind when you need it most.
Why You Can’t Skip Your Homework When Renting Underground Mining Equipment
Let’s face it – underground mining throws challenges at you that surface operations never deal with. You’ve got tight spaces, air quality concerns, and limited ways in and out. When equipment breaks down underground, your whole operation can grind to a halt.
The money side of things gets serious fast. That specialized piece of underground equipment might be supporting hundreds of thousands in daily production. When it fails, you’re not just paying for repairs – you’re dealing with idle workers, missed targets, and maybe even penalties for blown deadlines.
And let’s not forget safety. Well-maintained mining equipment that actually fits in your tunnels and has decent safety features is what stands between your team and potential disaster.
So let’s dig into what you should be asking before you rent anything.
Equipment Condition and Performance Questions
What’s the age, condition, and service history of this equipment?
Would you buy a used truck without checking if it’s been appropriately maintained? Probably not. But it’s amazing how many mining operations will drop serious cash on rental equipment without looking at maintenance records.
Get your hands on all the maintenance documentation – scheduled servicing, unexpected repairs, the works. Watch out for red flags like the same system needing fixes over and over, big gaps in the maintenance schedule, or vague paperwork that doesn’t tell you much.
At Tim McDowell Equipment, we’re obsessive about tracking this stuff. We keep detailed digital records for everything in our fleet from day one. We’re happy to share these records, too – it shows we stand behind our equipment.
When was the last inspection and certification?
Mining regulations don’t mess around these days. Your equipment needs regular professional inspections, and you need to see the paperwork.
Ask specifically about the last mechanical assessment, load testing if it applies, and when the safety systems were last checked. Get copies of these certificates before you commit to anything.
Our team does a 150-point inspection on every piece of underground equipment before it leaves our yard. It’s probably overkill, but we’d rather be thorough than sorry – and we’ll give you the detailed reports to prove it.
How reliable is this equipment actually going to be?
You need to know the Mean Time Between Failures (MTBF) – basically, how long this thing typically runs before something breaks.
A good supplier should have these numbers ready – not just vague promises that “it’s reliable.” Ask for the actual stats on uptime percentages.
We guarantee reliability at Tim McDowell Equipment with high availability rates for our underground fleet. That beats the industry average by a good margin because we know downtime is killing your profits.
Getting Support When You Need It
What kind of training and help comes with the equipment?
Even your most experienced operators need some guidance on new equipment, especially the high-tech stuff with all those electronic systems.
Find out if formal training is included, whether it’s hands-on or just a manual, and if you can get ongoing support during your rental.
How fast can I get help when something breaks?
Underground, every minute of downtime bleeds money. You need to know exactly how quickly help will arrive.
Get specific about guaranteed response times, whether technicians are on-call 24/7, and if they can diagnose problems remotely. Also, ask about parts – do they keep critical components in stock?
Can I talk to some of your other customers?
Past performance tells you a lot. Talking with current clients working in conditions like yours gives you the real story.
Ask for references from operations that match your mining method, depth, and production scale. When you call them, ask about equipment reliability, how quickly service issues were resolved, and if they’re generally happy with the relationship.
We’ve got clients all over North America and South America, from small development projects to major producers. We’re happy to connect you with operations similar to yours that can give you the unvarnished truth about working with us.

Making Sure It’s the Right Equipment
Will this actually work in my specific underground conditions?
Underground environments vary like crazy. Equipment that works great in a big, open mine might be useless in narrow-vein operations.
Share detailed specs of your drifts, declines, ventilation setup, and ground conditions. Get them to confirm in writing that the equipment dimensions, turning radius, and capabilities match your environment.
Our team specializes in matching equipment to specific underground conditions. We’ll analyze your operational parameters to recommend equipment that’ll actually work in your unique environment – not just whatever we happen to have sitting in the yard.
Does this meet all the current safety and emissions standards?
Regulations for underground equipment keep changing, especially around emissions and safety features.
Get documentation confirming compliance with current regulations where you operate. Ask specifically about diesel particulate filter systems, engine certifications, and operator protection features.
All our equipment meets or exceeds current regulatory standards. We stay ahead of compliance requirements so you don’t face delays or penalties related to equipment certification.
When Things Go Wrong
What happens if this thing breaks down?
Even well-maintained equipment occasionally has issues. You need to know how the supplier responds when problems happen.
Ask about replacement policies, repair timelines, and service level agreements. Do they offer credit for excessive downtime?
Our equipment guarantee includes rapid replacement options. If we can’t fix your equipment on-site within 24 hours, we’ll get you replacement machinery to keep your operation moving.
What if I need to cancel?
Mining operations sometimes face unexpected shutdowns. You need to understand your options for ending a rental agreement without bleeding money.
Get details about notice periods, early termination fees, and when penalties might be waived.
We offer reasonable cancellation policies that recognize mining is unpredictable. We’ll work with you to find solutions that work for both sides when circumstances change.
Thinking Long-Term
Can I eventually own this thing?
For growing operations, turning rental payments into ownership makes financial sense.
Ask if rental payments can count toward purchase, what percentage converts to equity, and what end-of-term options exist.
Our flexible acquisition programs let clients apply a good chunk of rental payments toward eventual purchase. This can really reduce total equipment costs for operations planning for the long haul.
What kind of relationship can I expect going forward?
The best equipment suppliers become partners, not just vendors. You want to understand the potential for a long-term relationship.
Ask about post-rental support, future equipment availability, and whether repeat customers get better terms.
As a family business, we value lasting relationships above all else. Our commitment goes beyond the initial rental agreement to supporting your operation’s long-term success.

Making Your Final Choice
When comparing suppliers, remember the lowest rental price rarely gives you the best value. Look at the whole picture:
- How reliable is the equipment, and what’s the uptime percentage?
- How good is the technical support and response time?
- How flexible are the terms and conditions?
- How transparent are they about costs and fees?
- How much experience do they have with your specific mining method?
We’d suggest making your own rental checklist based on what matters most to your operation. Use it consistently when looking at different suppliers so you’re comparing apples to apples.
