How to Calculate TCO for a Dorner Conveyor: A 5‑Step Checklist

When to Use This Checklist

You're evaluating Dorner conveyor systems and comparing quotes from local distributors or direct from Dorner. The base price looks reasonable, but you know from experience that the real cost hides in installation, integration, maintenance, and downtime. This checklist is for plant managers and procurement leads who want to avoid the classic “cheaper quote = higher total cost” trap.

I manage a ~$180,000 annual budget for material handling equipment at a mid‑size food processing facility. About 200 orders over 6 years have taught me where the money really goes. If you're dealing with luxury segments or ultra‑high‑volume operations, your numbers will differ — but the framework holds.

Step 1: Get the Base Price – But Ask for the “Inclusive” Version

You get a quote: $4,200 for a Dorner 2200 series conveyor, 10 feet. Sounds good. But always ask: “Does this include the gear motor, mounting brackets, and control wiring?”

In my first year, I made the classic rookie mistake: I compared base prices from three vendors without checking what was included. Vendor A quoted $3,800, Vendor B $4,200, and Vendor C $5,000. I almost went with A. Then I asked for an itemized breakdown. Vendor A added $450 for the gear motor, $300 for brackets, and $250 for wiring — total $4,800. Vendor B's $4,200 included everything. Vendor C's $5,000 also included installation and a 2‑year warranty.

Action: Request a “fully loaded” quote. Ask for the price as it will appear on the final invoice, including all standard components and any mandatory setup fees.

Step 2: Calculate Installation & Integration Costs

A conveyor doesn't magically work when it arrives. You need framing, alignment, electrical hookup, and often modifications to existing PLC controls. I've seen plants where the installation cost exceeded the purchase price.

For our Dorner 2200, we paid $1,200 for installation — two electricians for two days, plus a systems integrator for half a day to tie it into the line. That's $1,200 on top of $4,200. If you have an in‑house team, your labor might be lower, but don't forget the opportunity cost of pulling your technicians off other work.

Action: Get a separate installation quote or estimate from the vendor. Ask about training costs if the system uses a new controller. Per FTC guidelines on advertising, any claim of “easy installation” should be verified with a written estimate.

Step 3: Factor in Maintenance & Spare Parts

Dorner conveyors are modular — that's a huge advantage for TCO. But the true maintenance cost depends on your environment. In a peanut butter processing line (we run one), grease and residue accumulate on belts. We had to replace the belt every 18 months, at $600 each. Bearings every two years, $150.

If I track our 6‑year data, maintenance averages $320 per year for that conveyor. The cheap alternative I once considered (a non‑modular belt) had lower upfront cost but required full belt replacements ($1,200) and took twice as long to disassemble. That “cheap” option ended up costing us $8,400 more over five years.

Action: Ask the vendor for a recommended spare parts list and typical replacement intervals. Multiply by your expected life (I use 5–7 years for moderate use) to get the maintenance TCO component.

Step 4: Quantify Downtime Costs (The Hidden Monster)

This is where most project justifications fall short. Every hour your conveyor is down, you lose production. In our plant, a line making 2,000 peanut butter jars an hour at $0.35 profit per jar means $700 per hour of lost profit. A two‑hour unplanned breakdown wipes out $1,400.

I compare vendors not just on MTBF (mean time between failures) but also on mean time to repair (MTTR). Dorner's modular design allows swapping a drive motor in 20 minutes — that's a game‑changer. The competitor's system required unbolting the entire frame: 4 hours. Over 6 years, I estimate the downtime savings from Dorner's design were ~$12,000 for our two lines.

Action: Estimate your hourly lost profit. Multiply by the expected MTTR difference between options. Add that to your TCO spreadsheet. It's often the largest variable.

Step 5: Include Decommissioning & Resale Value

Most people ignore the end of life. But if you upgrade or repurpose the line, modular systems have residual value. We sold two used Dorner 2200 conveyors on the secondary market for 25% of original price — that's $1,050 back. A non‑modular competitor's conveyor was scrapped for $100.

Action: Ask the vendor about trade‑in programs or typical resale percentages. Factor in disposal costs if the system has hazardous components (some gear motors contain oil).

Common Mistakes & Watch‑Outs

• Comparing annual maintenance without inflation. Parts prices go up roughly 3–4% per year. Use a 3% annual escalation in your TCO model.
• Ignoring your own team's learning curve. A new system might require retraining — that's time you're paying for. Budget a day of two technicians at $50/hour each = $800.
• Assuming quoted lead times are accurate. I ordered a Dorner system that was supposed to ship in 4 weeks; it took 6. That delay cost us $1,200 in idle labor. Add a 20% buffer on lead time in your project plan.
• Overlooking energy consumption. Two similar conveyors can draw different wattage. Over 10 years at $0.12/kWh, a 200W difference adds up to ~$2,100. Ask for the motor efficiency class.

Honestly, no calculator will be 100% accurate. My experience is based on about 200 mid‑range orders for food and beverage plants. If you're working with heavy‑duty mining conveyors (like some Dorner customers), your maintenance and downtime costs will be much higher. But the checklist structure works the same.

I've only worked with domestic vendors, so I can't speak to international sourcing. The numbers I gave are from our internal cost tracking system — verified against invoices from 2019 through 2024. If you run your own numbers, I guarantee you'll find at least one surprise.
