How to Evaluate McLanahan Equipment Purchases: A 5-Step TCO Checklist for Procurement Managers

When This Checklist Helps

You're responsible for ordering heavy equipment for your aggregate or mining operation. Maybe you've been asked to quote a McLanahan sand screw or a feeder breaker. The supplier's base price looks competitive, but you've been burned before by hidden costs—rush shipping, installation surprises, parts that aren't stocked locally.

This checklist is for anyone who manages capital equipment procurement and wants to move past the sticker price. I've been handling these orders since 2020, and the mistakes I've made have taught me one thing: the cheapest quote rarely stays cheap.

Here are the 5 steps I now run through before signing off on any McLanahan equipment purchase.

Step 1: Verify the Core Spec Against Your Actual Load

First things first—don't assume a model number matches your needs. I once ordered a McLanahan 36" diameter twin screw washer because the brochure said it could handle 300 TPH. Turned out our feed material had higher clay content than the spec assumed. We ended up with a bottleneck within six months.

Checklist:

• Confirm feed material characteristics (moisture, abrasion, particle size distribution)
• Ask the McLanahan rep for the actual throughput curve, not just the peak rating
• Request a site visit report if available—especially for customized feeder breakers

I've learned the hard way: a 10% over-spec now saves hours of rework later. But don't over-spec by 50% unless you're planning to expand—that's just wasted capital.

Step 2: Map Out the Full Installation Cost—Not Just the Equipment Price

The quote might say $350,000 for a McLanahan filter press. Great. But where does it sit? Our facility needed a reinforced concrete pad, hydraulic connections, and a separate electrical panel upgrade. That added $47,000—almost 14% on top.

Things to include in your TCO estimate:

• Foundation or mounting requirements
• Electrical and plumbing modifications
• Rigging and crane rental for offloading (especially for large feeder breakers)
• Permits or inspections (some counties require structural engineer sign-off)

When I started estimating these separately, I stopped getting surprised by change orders. Your finance team will thank you.

Step 3: Calculate Ongoing Operating Costs (The One Most People Miss)

This is where the total cost thinking really kicks in. A McLanahan sand screw might have lower power draw than a competitor's, but if replacement wear shoes need to be imported from the UK every six months, that's a recurring cost many buyers ignore.

Hidden operating costs to estimate:

• Wear parts frequency and lead time (ask for the average life in YOUR material)
• Energy consumption per ton—McLanahan publishes some data, but ask for it in kWh/ton for your specific model
• Planned maintenance intervals—how many labor hours per quarter?
• Spare parts availability: are critical components stocked in your region? (McLanahan has service centers in US, UK, India, Australia—find out which one covers you)

To be fair, some of these numbers are estimates. But ask the vendor for a "typical annual cost of ownership" spreadsheet. If they can't provide it, that's a red flag.

Step 4: Factor in Downtime Risk and Service Response

I'm not 100% sure about the exact math, but I've seen a single day of unplanned downtime cost our operation around $12,000 in lost production. Multiply that by the average repair time for a feeder breaker gearbox—maybe 3 days—and you're looking at $36,000 risk.

Questions to ask before committing:

• What is the standard lead time for emergency parts?
• Does McLanahan offer remote diagnostics? (Some of their newer filter presses have IoT monitoring.)
• Is there a local service technician within 200 miles? If not, what's the travel charge?
• Can you get a spare parts kit built into the purchase agreement?

I once skipped this step on a similar brand's equipment. When the hydraulic pump failed on a Friday, we couldn't get a replacement until Wednesday. The VP asked why we didn't buy the spare kit upfront. Lesson learned.

Step 5: Compare Total Cost Over Five Years—Not Just Upfront

This is the final gut check. Take your numbers from steps 1-4 and build a simple spreadsheet: purchase price + installation + 5 years of operating costs + estimated downtime cost = TCO.

Example (based on a recent quote I processed):

Cost Category	Quote A (Competitor)	Quote B (McLanahan)
Base equipment	$290,000	$315,000
Installation	$42,000	$38,000
5-year wear parts	$65,000	$48,000
Energy cost (5 yr)	$72,000	$61,000
Estimated downtime risk	$18,000	$8,000
Total 5-year TCO	$487,000	$470,000

In this case, the McLanahan unit was more expensive upfront but came out ahead on TCO. That's the kind of data that makes your operations manager nod and your finance controller relax.

Common Mistakes to Avoid

1. Trusting the list price without verifying – A discount might hide a stripped-down configuration. Always cross-check the spec sheet.

2. Skipping the site survey – I almost approved a $400,000 feeder breaker that wouldn't fit through our existing conveyor tunnel. A site visit would have caught it.

3. Forgetting about training – New equipment often requires operator and maintenance training. Factor that into installation cost.

4. Assuming all quotes include the same scope – One vendor might include start-up commissioning, another treats it as a separate line item. Read the fine print.

5. Not asking about obsolescence – McLanahan has been around since 1835, but models evolve. Ask how long spare parts will be supported for the model you're buying.

This checklist is based on my own experience as an administrative buyer handling 60-80 equipment orders annually. Your numbers will vary. Always verify current pricing with McLanahan or your local distributor. As of February 2025, I've found their service team responsive, but I still run this checklist every single time.
