I review crane specifications for a living. Over the past four years, I’ve seen roughly 200+ crane procurement projects—from small workshop hoists to 50-ton overhead bridge systems. About 30% of first deliveries get rejected because the specs don’t match what was agreed. And in almost every case, the root cause traces back to a single decision: going with the cheapest quote.
What You’re Actually Comparing: New Demag vs. Used Demag
If you’re searching for “Demag cranes for sale,” you’re probably looking at two broad categories: factory-new units (or certified refurbished from authorized dealers) and used/pre-owned cranes from auction houses, brokers, or plant closures. The question isn’t just which is cheaper—it’s which delivers the total value your operation needs over the next 5–10 years.
Let’s break this down the way I do during a vendor audit: by the dimensions that actually affect your bottom line.
Dimension 1: Specification Guarantee
New Demag overhead crane: You get a factory spec sheet with certified load ratings, duty cycles (CMAA class, FEM group), hoist speeds, and component serial numbers. Every weld, motor, and control panel is traceable to Demag’s manufacturing records. If the crane says 10-ton capacity at 25m span, you can bet your insurance auditor will accept that certificate.
Used Demag crane: The listing might say “10-ton Demag overhead crane, 1978 vintage, currently installed at a steel mill.” But what does “10-ton” really mean after decades of service? I’ve seen used cranes sold with missing load test certificates, altered hoists, or re-welded end trucks that don’t meet original tolerances. In Q1 2024, we rejected a used crane from a broker because the main girder deflection was 30% beyond the allowable standard—they claimed it was “within industry limits.” We measured it. It wasn’t.
Conclusion: If the spec must be verified for safety and compliance, new or certified refurbished wins. But if you have an internal engineering team that can inspect and recertify, a used Demag can be a great value—provided you budget $3,000–$8,000 for a thorough third-party inspection and possible component replacement.
Dimension 2: Spare Parts Availability
New Demag: Every part number is current. You order a hoist motor brake coil, it arrives in 2–5 days. Demag’s parts network (now under Konecranes service, with mobile crane heritage from Tadano) covers all current models seamlessly.
Used Demag: This is where surprises hide. A used crane from the 1990s might use proprietary Demag controls that are no longer manufactured. I worked on a project where a 1985 Demag double-girder crane needed a travel motor. The broker said “just retrofit a standard motor.” That retrofit cost $4,200 and took three weeks of custom adapter plates and rewiring. Meanwhile, the crane was down. The “savings” of buying used ($12,000 versus $38,000 new) evaporated after factoring in downtime and the retrofit.
Conclusion: If you can document the exact model year and component serial numbers before purchase, and verify that common spares (motors, brakes, controls) are still available, used is viable. Otherwise, new gives you parts certainty for the next 20 years.
Dimension 3: Total Cost of Ownership (5-Year View)
I ran a blind comparison two years ago between a new Demag 10-ton overhead crane (quoted at $48,000 installed) and a used 2004 Demag of similar capacity ($22,000 as-is, plus rigging). The used unit required:
- Full inspection ($2,800)
- New hoist brake ($1,200)
- Control panel upgrade ($3,500)
- Two weeks of downtime during commissioning
Total used cost: ~$29,500 + lost production value (~$9,000 estimated). That’s $38,500. Not far from the new price. But the used crane still had a shorter remaining service life (estimated 15 years vs. 25+ for new), and the contractor’s warranty was only 90 days versus the new unit’s 2-year factory warranty.
Conclusion: The lowest upfront quote is rarely the lowest total cost. If you have a tight budget and can accept moderate risk, used can work—especially for non-critical applications (e.g., light maintenance shop vs. high-frequency production line). But for continuous operation where a breakdown costs your line $3,000/hour, new or certified refurbished is almost always the smarter investment.
When to Choose New Demag Overhead Crane
- You need a specific duty class (e.g., CMAA Class D or E for heavy use)
- You require a factory load test certificate for insurance/compliance
- You want a 2+ year warranty and guaranteed parts availability
- The crane will be used 8+ hours/day, 5+ days a week
When Used Demag Cranes for Sale Make Sense
- Your maintenance team can inspect and recertify in-house
- The crane is for intermittent, <10 lifts/day
- You find a late-model (post-2010) Demag with documented service history
- You have time to wait for retrofit parts
In my experience, about 40% of used crane purchases end up costing more than a new equivalent within three years. But the other 60% can be genuine bargains—if you’re willing to do the legwork. Start by asking every seller for the original crane serial plate photo, the last service report, and a signed statement on the current load test certification. If they hesitate, walk away.
