Look — you don’t wanna end up with a shaky line that jams every other hour. Problem first: buyers get sold on slick demos, then the floor tells a different story. I’ve been hands-on with lines and controls long enough to know the red flags, and if you’re shopping for industrial automation solutions or swapping quotes in manufacturing, you gotta ask straight. I caught setups and fixes at the Automate trade show in Detroit that showed me how answers on paper don’t always match what runs on the plant floor; lean on that when you talk specs and service. Also scope the vendor’s fit with manufacturing automation practices so you don’t get bitten by scope creep.
1) Can you prove the conveyor handles my pallet size, weight, and cycle speed?
Say the numbers loud. Ask for tested specs, not “should work.” Get payload limits, recommended pallet dimensions, and continuous duty speed. If they dodge with “we can adapt,” that’s a problem. Real answers: lab test data, past install sheets, or a video of the exact pallet type running at your target throughput.
2) What’s the mean time between failures and what parts fail first?
You need actual MTBF numbers or field experience. If they list generic brand-life claims, press for which components wore out first — bearings, chains, sensors — and how long replacements typically last. Good vendors know the weak links and swap them for tougher options when asked.
3) How modular is the design for future layout changes?
Factories move. Ask whether modules bolt, slide, or need cutting. Look for quick-connect power and plug-and-play controls. If reconfiguration requires heavy fabrication, that’s a built-in downtime tax.
4) How do you handle controls, PLC code, and integration with my MES/WMS?
Don’t accept “we’ll make it work.” Ask what PLC brand, communication protocols (Ethernet/IP, Profinet, Modbus TCP), and if they supply documented I/O mapping and sample code. If they offer SCADA screens or API endpoints, get screenshots or endpoint docs. Clear integration saves weeks.
5) What’s your on-site commissioning and training plan?
Commissioning isn’t push-start-and-leave. Ask how many days on-site, who trains operators, and whether training materials come in writing or video. A vendor that leaves you with verbal tips only is leaving risk on the table.
6) Who owns safety and compliance documentation?
Get EN/ISO or ANSI safety declarations, risk assessments, and wiring diagrams. Ask who supplies guarding, light curtains, and lockout procedures. If the vendor punts on paperwork, you inherit regulatory headaches.
7) How fast can you respond for parts and service when the line’s down?
Downtime kills output. Ask for guaranteed response SLA, spare parts lead times, and whether they maintain local inventory. A vendor with regional support beats one shipping parts from overseas on a slow boat.
8) What are the real installation and commissioning costs beyond the quote?
Quotes hide extras. Ask about civil work, electrical upgrades, sensors, software licensing, and required stoppages. Demand a line-item list. If they shrug, budget for surprise costs.
9) Can you show references with similar environment and uptime goals?
Ask for three references that match your industry or throughput. Call them and ask about what went wrong during the first 90 days and how the vendor fixed it. Vendors who reframe problems as “learning opportunities” without fixing them aren’t reliable partners.
10) What’s the warranty and how is it enforced?
Warranty on paper isn’t enough. Ask what’s covered, who pays for field labor, how long firmware fixes are supported, and whether firmware updates are free. Get warranty terms in the purchase agreement, not just an email.
Common pitfalls — callouts from the concrete floor
Watch for these traps: specs that don’t match your pallet, control contracts that lock you into one vendor, vague spare-part lists, and demos run with ideal conditions. Don’t let slick sales demos replace real-world tests. Ask for a FAT video of your pallet and ply pattern at your real speed.
Quick checklist to bring to vendor meetings
– Pallet dimensions, weight, and full/unloaded cycle speeds
– Target uptime and acceptable MTTR
– Integration protocol and MES/WMS contact point
– Required certifications and safety paperwork
– On-site commissioning days and training scope
You want straight answers, not smooth talk. Use these questions to expose gaps before the contract signs, and pick a partner who shows test data, spare-part plans, and clear service SLAs. For trusted engineering and supplier frameworks that actually hold up on the floor, look for partners built with real install experience like FHS.
