If you're looking at demag cranes for sale, you've probably already read the brochures. They're German engineering, they're reliable, they're the benchmark. I get it.
Here's what the brochures don't tell you—stuff I only learned by making a few expensive mistakes. I maintain our factory's equipment checklist now, and these are the questions I wish someone had asked me before my first purchase.
1. What's the difference between a Demag crane and a Demag hoist?
This sounds basic, but I've seen people use the terms interchangeably and end up with the wrong thing. A demag crane is the whole system—the bridge, the end trucks, the runway, the controls. The demag hoist is the lifting mechanism (the motor, drum, and hook) that hangs off that bridge.
When you see demag cranes for sale, make sure you know whether you're buying a complete system or just a hoist to retrofit onto existing rails. In my first year (2017), I ordered a hoist thinking it was a full crane. The result: $3,200 in equipment I couldn't use for a month while we sourced the missing parts. That mistake alone taught me to read the spec sheet three times.
2. How do I find a reliable Demag dealer?
Not all dealers are equal. The conventional wisdom is to pick the closest one. My experience with 200+ orders suggests otherwise.
A good demag dealer does three things:
- They ask about your specific load profile (not just max weight).
- They can provide reference installations you can call.
- They're transparent about lead times—especially on parts.
I once chose a dealer based on a low quote. The catch? They didn't stock common parts. When I needed a replacement for a demag electric hoist, the lead time was 8 weeks. For a part that should've been a week, max. The conventional wisdom says low price wins. In practice, for critical equipment, proximity and parts availability matter more.
3. What does 'used Demag crane' actually mean?
Used demag cranes for sale are popular because the brand holds up. But “used” can mean anything from a 6-month-old demo unit to a 20-year-old retired system from a foundry.
My sample limitation: The used cranes I've dealt with were mostly from warehouse applications. If you're buying one from a steel mill or a foundry, your inspection checklist needs to be different. Here's what I check on a used Demag hoist:
1. The load chain or wire rope for wear. Demag hoists are precise, but abuse shows fast.
2. The motor brake. If it's been slipped (burnt), that's a $1,000+ rebuild.
3. The control panel. Look for signs of moisture or corrosion.
4. The serial number. You can call Demag to verify the original specs.
Don't hold me to this, but based on quotes I've seen, a used Demag crane in good condition is typically 40-60% of new pricing. A neglected one? It's not a bargain—it's a future headache.
4. Why would a GFCI breaker matter for a crane installation?
This is one of those questions nobody asks until something trips. In industrial settings, especially when you're installing a crane in a facility that originally wasn't designed for it—like adapting a tractor supply building—the power supply can be unpredictable.
A gfci breaker (Ground Fault Circuit Interrupter) is sometimes required by code if the crane or its controls are in a wet or outdoor environment. I once ordered a demag electric hoist with a standard plug, then discovered the local inspector required GFCI protection for that location. The wrong circuit had to be rewired at a cost of $450 plus a 3-day delay.
What I learned: Always check the local electrical code before you finalize the crane specs. Your demag dealer should ask about this. If they don't, raise the flag yourself.
5. Is a Demag hoist overkill for light-duty use?
This depends on what you mean by “light-duty.” If you're lifting 500 lbs once a week, a $2,000 chain hoist from a generic brand will work. But if you're lifting 500 lbs every hour, the duty cycle of the motor matters.
Demag hoists (especially the Demag DC chain hoist and the DK electric chain hoist) are rated for heavy-duty industrial cycles. The conventional wisdom is that you're paying a premium for the name. In practice, for continuous use, the Demag motor runs cooler and lasts longer. I'd argue the premium is justified—but only if you're actually using it at those cycles. For occasional use, you're paying for capability you'll never use.
Everything I'd read said premium options always outperform budget ones. In practice, for our specific use case (moderate frequency, 1-ton loads), the mid-tier option actually delivered better value. That's not a popular opinion among the Demag loyalists, but it's what I've seen.
6. What should I ask before buying parts for an existing Demag crane?
Demag crane parts are designed to be modular, but the generation matters. A part for a 2010 hoist might not fit a 2020 model—even if they look identical.
Here's something dealers won't tell you: the serial number is everything. If you're ordering replacement parts, always have the model number and serial number ready. I once ordered a replacement trolley for a demag electric hoist based on a photo. It arrived with the wrong bolt pattern. $890 in return shipping and restocking fees later, I learned to never order by photo.
My advice? Take a photo of the nameplate. Every Demag hoist has one. Send that to your dealer. It takes two minutes and saves weeks of frustration.
7. What is a crane? (Seriously, for non-engineers)
If you're a small business owner or a maintenance supervisor at a tractor supply-type facility, you might be asking: what is a crane in practical terms?
A crane is a machine that lifts and moves heavy loads. That's obvious. But the specific type matters:
Overhead crane: A bridge that runs on rails on the ceiling. The hoist moves left/right along the bridge, and the bridge moves forward/backward along the runway. This gives you coverage over a rectangular area.
Gantry crane: Like an overhead crane, but it stands on legs instead of hanging from the ceiling.
Jib crane: A single arm that rotates around a pivot. Good for a single workstation.
Hoist itself: Just the lifting part—can be mounted on a beam, a trolley, or a gantry.
When people search for demag cranes for sale, 90% of the time they need an overhead bridge crane. But I've seen buyers order a hoist expecting it to be a full crane. So to be clear: you need the whole system (rails, bridge, end trucks, hoist, controls) for a complete installation. The hoist alone is just the lifting guts.
Take this with a grain of salt: I've only worked with overhead cranes up to 10 tons. If you're looking at a 50-ton system, your requirements will be different.
After 7 years of buying, installing, and occasionally breaking Demag equipment, here's my bottom line: the brand is great, but the process matters more. Find a dealer who asks the right questions. Verify your specs. And for heaven's sake, check the serial number before you order parts. I've made (and documented) enough mistakes for both of us.
