A Quality Inspector's Checklist for Sourcing a Kleemann Mobile Crusher

A 9-Step Checklist for Vetting a Kleemann Crusher Before You Buy

I review spec sheets, supplier documentation, and first-article inspections before they reach our procurement team. Roughly 180 crusher and screen packages a year—mobile jaw, cone, impact, and scalping decks. I rejected about 15% of first deliveries in 2024 because the paperwork did not match the iron. When I first started reviewing crusher specs, I assumed the lowest cost per ton was the only number that mattered. I was wrong. Three downtime events later, I learned that rock crusher sourcing is a total-cost exercise, not a price-shopping exercise.

What follows is the 9-step checklist I use before we sign off on a Kleemann crusher—or any bulk crusher. It is written for contractors, quarry operators, and dealers who need to compare a Kleemann MOBICAT MC 110i EVO2 against other options without getting buried in brochure numbers.

Step 1: Define the application before you look at the machine

Most buyers start with the crusher. That is backwards. Write a one-page feed and product spec first: rock type, bulk density, maximum feed size, moisture, clay content, rebar or not, and target product sizes. A jaw crusher like the Kleemann MOBICAT MC 110i EVO2 is usually a primary unit. If you need cubical aggregates, an impact crusher may be a better fit. If you need secondary hard-rock reduction, look at a cone. Do not let a crusher specification guide choose your process for you. If you are a dealer, ask what your customers actually feed their crushers. The answer is often different from the OEM demo material.

Step 2: Verify the published spec sheet against your site

Take the Kleemann MOBICAT MC 110i EVO2 spec sheet from Kleemann or Wirtgen Group and check transport dimensions, weight, feed opening, CSS range, hopper volume, discharge height, and stockpile conveyor height. I am not 100% sure why buyers skip transport width, but I have seen a machine arrive that could not fit the haul road. (Note to self: add haul road width to our standard RFQ.) What looks fine on a PDF can be a problem on a narrow bench. For a MOBICAT MC 110i EVO2, the feed opening and discharge conveyor are usually the two dimensions that decide whether the machine fits your process. But transport weight matters for permits, too.

Step 3: Check emissions and power compliance for your region

EU Stage V or EPA Tier 4 Final depends on where you operate. Do not assume the spec sheet you downloaded applies to your market. Ask for the regional variant, the engine certification, and the warranty coverage for that configuration. ISO 21873-1 covers safety requirements for mobile crushing and screening equipment; use it as a baseline when you review guarding, emergency stops, and access platforms. If you run in a city, noise and dust regulations can matter as much as emissions.

Step 4: Audit wear parts and OEM traceability

This is the step most people ignore. A Kleemann crusher may have a great jaw box, but if the jaw plates, cheek plates, and liners are not sourced correctly, you will pay for it in downtime. I have mixed feelings about aftermarket wear parts. On one hand, they can be cheaper. On the other, I have seen a non-OEM jaw plate fail early and stop a shift. The lost production usually dwarfs the part price. Ask for OEM part numbers, wear life estimates, and local stock levels before you commit. I have a self-reminder in my checklist: ask for the last three wear-life reports. If the dealer cannot produce them, I assume the wear life claim is a guess.

Step 5: Calculate realistic throughput

Brochure throughput is usually optimistic. Take this with a grain of salt, but in hard rock with fines and moisture, you can lose 20 to 40 percent of the published number. Use bulk density, crusher CSS, and screen area. For a bulk crusher, ask the dealer to model your material, not their demo pile. If they cannot show you a realistic tonnage curve, that is a fairly big warning sign. For a jaw crusher, the reduction ratio and feed grading matter. For a cone, the chamber selection matters. For an impactor, the blow bar metallurgy matters.

Step 6: Build a total cost of ownership model

Price per unit is easy. TCO is where the real decision lives. Include purchase price, freight, commissioning, operator training, fuel or electric cost, wear parts, planned maintenance, unplanned downtime, parts logistics, and resale value. In my experience managing 120+ sourcing projects over 4 years, the lowest quote has cost us more in about 60% of cases. That $300 cheaper belt can turn into a $3,000 cleanup if it fails under load. Value over price is not a slogan; it is a spreadsheet exercise. I have also started adding downtime cost per hour. If your plant loses $2,000 an hour, a one-day parts delay is a $16,000 problem—not a $500 part.

Step 7: Verify dealer support and parts logistics

Kleemann has a dealer network, but not all dealers are equal. Ask: How many Kleemann crushers do you support? What is your average response time? Do you stock MOBICAT MC 110i EVO2 wear parts locally? Can you provide a technician within 24 hours? Get it in writing. Honestly, I am not sure why some dealers can get wear parts overnight while others take a week. My best guess is local stock and service depth. Some dealers are great at sales and weak at service. The service side is what you live with after the invoice.

Step 8: Run reference checks with similar operations

Call three operators running a similar Kleemann crusher in similar rock. Ask about downtime, parts delays, fuel burn, and dealer response. Not the sales rep's reference list—your own list. The surprise is not usually the price difference. It is how much hidden value comes with good support. Ask what broke, how long the fix took, and whether they would buy the same machine again. The third question is the one that gets honest answers. This worked for us, but we run hard rock in a quarry with fairly stable feed. If you are recycling C&D with rebar, the calculus might be different.

Step 9: Document acceptance criteria before you order

Before signing, write down feed opening tolerance, CSS range verification, throughput test material, wear part part numbers, commissioning checklist, training hours, and warranty terms. In our Q1 2024 quality audit, we found that 22% of crusher delivery disputes came from vague specs. Now every contract includes measurable acceptance criteria. Include a pre-delivery inspection and a signed punch list. Do not release final payment until the punch list is closed. That one step has saved us more than any negotiation on the purchase price.

Common mistakes I still see

• Comparing price per unit instead of cost per ton.
• Assuming the spec sheet is the same for every region.
• Ignoring transport and site access.
• Skipping the wear parts audit.
• Not asking for a TCO model.
• Forgetting operator training. A good crusher with a poorly trained operator is an expensive way to make off-spec product.
• Buying a machine for a one-off project when the utilization does not justify ownership.

I can only speak to domestic operations. If you are dealing with international logistics, there are probably factors I am not aware of. The goal is not to buy the cheapest Kleemann crusher. It is to buy the right one and keep it running. For a bulk crusher, rock crusher sourcing, or a crusher specification guide, the best number is rarely the lowest quote—it is the lowest total cost per ton produced.
