Demag Crane Buying Scenarios: Three Paths, Three Different Answers

Three Ways People Buy Demag Cranes — and Why One Checklist Doesn't Fit All

Ask five people how to buy a Demag crane and you'll get five different answers. Not because four of them are wrong — because they're buying for four different situations, and nobody bothered to check which one you're in.

I've been handling crane and hoist orders for nine years. In that time I've personally made — and documented — 14 significant purchasing mistakes totaling roughly $23,000 in wasted budget. Every single one of those mistakes came from applying the right answer to the wrong scenario. So before any advice lands, figure out which of these three you actually are.

• Scenario A — The Project Buyer: You need one crane, maybe two, for a specific site or a specific job. Mobile, crawler, or truck-mounted.
• Scenario B — The Facility Buyer: You're specifying an overhead or gantry crane for a building, and it'll live there for 15+ years.
• Scenario C — The Channel Buyer: You're a distributor or stocking partner covering a region.

These three have almost nothing in common. The advice that saves a project buyer money will cost a facility buyer a fortune, and vice versa.

Scenario A: You're Specifying a Single Mobile or Truck Crane

You need one crane, maybe two, for a specific site or a specific job. The machine leaves when the job does. You're renting capacity by the day.

What actually matters here

Most buyers open the truck crane specification guide, find the headline lifting capacity, and stop there. That number is a sales figure. The number that decides whether your lift works is the rated curve at your actual working radius with your actual boom configuration — and those two numbers can be 60% apart. So what should the spec sheet actually be telling you? Look for the chart, not the banner.

The bigger trap is ground conditions. On paper, a 200-tonne machine clears your lift with margin. If your site only allows half-extended outriggers, the capacity chart drops hard. I approved a spec in September 2022 using full-outrigger numbers for a site that could only take partial extension. Caught it two days before signing. The revised chart put us 12% short at the required radius. So glad I re-read the outrigger page — we were one signature away from a crane that physically could not make the lift.

Run the road-legal question early too. Axle load limits and permit thresholds on public roads, not just the site pad. A crane that's perfect on the pad and illegal on the highway is not a crane you can use.

The counterintuitive part

Bigger isn't safer. For a project buyer, running two mid-size Demag cranes on the same site often beats owning one oversized unit that sits idle between jobs. You win on utilization, and you stop paying insurance, inspection, and maintenance on capacity you need twice a year.

Scenario B: You're an Overhead Crane OEM Buyer — Equipping a Facility

You're specifying an overhead or gantry crane for a building. The machine will live in one bay for ten to twenty years. This is where I've seen the most expensive mistakes, because the errors don't show up for three or four years.

Duty classification comes before capacity

Forget tonnage for a moment. The classification comes first.

ISO 4301-1:2016 assigns each crane a class from A1 to A8 based on total load cycles, and each mechanism gets its own M1 to M8 designation. Two cranes with identical lifting capacity can carry A3 and A6 ratings, look the same on the drawing, and have wildly different service lives. An A3 machine running an A6 duty cycle will eat wire ropes and brake linings years ahead of schedule.

Most buyers focus on rated capacity and completely miss the service class. I've watched an overhead crane OEM quote us an A3 unit for a foundry bay where the real cycle count was closer to A6. The quote was 22% cheaper. So was the service life.

Standard references for this category: ASME B30.2 for overhead and gantry cranes in North America, EN 15011 and EN 13001 in Europe, with inspection intervals per ISO 9927-1:2013. Verify the current edition at the issuing body before you sign anything.

The overlooked number

The question everyone asks is how much can it lift. The question they should ask is how much hook height budget do we actually have. You measure the building, add the hook block, subtract the lowest obstructing beam, then subtract another 500 mm for trolley approach. Then you ask whether a mezzanine is ever going into that bay. I've seen three retrofits in nine years where a crane had to be raised because nobody modeled the future floor plan.

On the Demag crane models side, the lineup covers single girder, double girder, gantry, and wall-mounted configurations. Each one changes your hook approach dimensions and your headroom math. Which model works is a function of your building, not your budget.

On parts and components

For an overhead crane running five days a week, genuine OEM parts and components aren't a premium — they're the maintenance schedule itself. Service intervals in the manual assume original-spec components. Swap in a substitute and you own the consequences, because the inspection criteria in the standard do not bend to accommodate it.

Scenario C: The Channel Buyer — Distributor or Stocking Partner

You carry inventory, you serve a region, and — if you're doing it right — you make your money on service and repeat business, not on the margin from the first machine.

What actually matters here

Product line breadth. Being able to walk into a customer site and quote mobile, crawler, overhead, gantry, tower crane, and hoist requirements from one catalog is worth more than a slightly better discount tier. It means one relationship, one purchase order, one service history.

Parts supply lead time comes next. A distributor who sells a machine and then spends three weeks chasing a brake spring from 800 km away does not get the second order. Genuine OEM parts availability — documented and predictable — is the single biggest retention driver I've tracked across our own accounts.

The one that surprises people

Everything I'd read about distribution said the job is to win on local price. In practice, across 200+ orders, the distributors who lead with responsiveness and parts certainty hold accounts three to four years longer than the ones who lead with price. Price gets you the first quote. Response time gets you the fourth.

Worth noting for anyone entering the channel: the tower crane distributor path in particular rewards parts infrastructure over sales volume. Tower cranes sit on job sites for years and every one of them consumes components on a schedule. Sell the machine. Service the schedule.

How to Tell Which Scenario You're Actually In

Answer these three, in order. Don't skip ahead.

1. Will you buy another crane within 18 months? If yes, you're a project buyer. Optimize for site fit and flexibility, not residual value.
2. Will this crane stay in one building for a decade or more? If yes, you're a facility buyer. Spend the extra week on duty classification and hook height budget — those decisions are permanent and expensive to reverse.
3. Does your revenue come from selling machines, or from keeping them running? If it's the latter, you're a channel buyer. Your product is uptime, and your catalog breadth is your sales team.

If you answered no to all three, you're in a fourth situation I haven't covered — typically a one-off retrofit or a leased asset. Treat it as a project purchase and add a service contract review, because the exit cost is where those deals go wrong.

The trap isn't bad advice. It's good advice applied to the wrong situation. The checklist I keep now is one page and starts with a single line: which scenario am I in? Everything after that gets easier, and the $23,000 spread across 14 mistakes has stayed at $23,000 for eighteen months.
