Demag Hoist Parts List & Common Questions: A Field Guide Based on Real Mistakes

Demag Hoist Parts: The FAQ I Wish I'd Had When I Started

I've been handling parts orders for industrial cranes for about 7 years now. In my first year (2017), I made what I thought was a 'simple' mistake—I ordered the wrong hoist motor for a Demag PK chain hoist. The result: $890 in additional freight, a 2-week delay, and a very patient (but annoyed) client. After the third rejection in Q1 2024, I finally created our department's pre-check list. This FAQ covers what I've learned the hard way.

If you're looking for a generic 'Demag hoist parts list PDF' that covers everything, I don't have that exact file. What I can share is the list of questions and decisions that trip up most buyers—including myself.

Q1: What is a 'Demag Hoist Parts List' and where do I find the right one?

Let's be clear: there isn't one single 'Demag hoist parts list.' Demag (now part of Tadano's mobile crane lineage and Konecranes' industrial side) produced dozens of hoist models over decades—PK, DK, Type E, DH, and more. Each has its own parts breakdown.

The most frustrating part of this process: you can find a 'parts list' online, but it might be for a model discontinued 15 years ago. You'd think a model number like 'PK-5' is straightforward, but production changes, minor revisions, and different lifting heights all change the exact part numbers. I've personally made $3,200 in wrong orders (not a number I'm proud of) due to using the wrong revision of a parts list.

Where to start:

• Check the hoist's nameplate. You need the exact type/size (e.g., 'PK-5'), serial number, and year of manufacture (if visible).
• Look for a manufacturer's 'spare parts catalog' specific to that model. Tadano or Konecranes distributors can provide these, but expect to pay a small fee for older models.
• I don't have hard data on how many serial numbers actually have a matching digital catalog, but based on my experience, roughly 60-70% of requests for hoists from the 1990s or earlier will require cross-referencing with a physical archive.

Q2: I need a 'hoist motor' for my Demag crane. Is it the same as the original?

Probably not, and that's a big trap. I once ordered 15 'replacement' motors for a fleet of Demag DK hoists (circa 2005). They looked fine on my screen. The result: they came back—15 units, $2,100 worth of parts—straight to the trash. The mounting flange had been revised. The electrical connection box was rotated 90 degrees.

The lesson: never assume 'replacement' or 'compatible' means physically identical. Demag's electric motors—especially the self-braking designs—are specific to the hoist's duty cycle and mounting interface.

What to do instead:

• Get the original motor's type plate data (voltage, kW, RPM, IP rating).
• Check for a 'motor adaptor kit' or 'conversion set.' The vendor who says 'this isn't our specialty—here's who does the conversion' earned my trust for everything else. (I'd rather work with a specialist who knows their limits than a generalist who overpromises.)

Q3: What about 'scraper' and 'engine hoist'—are these related to Demag cranes?

Not directly, but they come up in the same search queries. Let me clarify:

• Scraper: Typically refers to heavy earthmoving equipment (like a scraper loader), not an overhead crane part. If you're searching for 'Demag scraper,' you might be looking for a component like a 'current collector' or 'sliding shoe' for a crane runway—which is sometimes called a 'scraper' in older translation manuals. (Note to self: verify this terminology with the distributor).
• Engine hoist: Also called a 'shop crane.' This is a mobile lifting frame, not an overhead crane. Demag did not manufacture engine hoists; this term usually points to brands like Strongway or OTC (at least, that's been my experience).

If you're looking for a Demag-specific lifting device, double-check the machine type. A common mistake is confusing a 'Demag mobile crane' (the big crawler or truck-mounted units) with 'Demag overhead crane' components. The parts are not interchangeable.

Q4: What is a 'forklift' and why do people confuse it with overhead cranes?

This is a classic search confusion. A forklift is a powered industrial truck used to lift and move materials over short distances (typically a few feet). An overhead crane (Demag's core product) uses a trolley on a runway to lift loads overhead.

Why the confusion? In some old warehouses, a 'forklift' operator might also use an 'overhead hoist' for heavy loads. The term 'hoist' is often misapplied. If you're looking for 'Demag forklift,' you probably mean a 'Demag hoist' mounted on a trolley or a dedicated lifting attachment. If you actually need a forklift (for pallets, etc.), you're looking at Toyota, Caterpillar, or Crown—not Demag.

The vendor who says 'this isn't our strength—here's who does it better' earned my trust for everything else. I've seen it happen: a client ordered a 'Demag forklift' part, but what they needed was a simple hoist chain. (This was back in 2022). The wrong item cost $450 plus a 1-week delay.

Q5: How do I verify I'm ordering the right replacement part?

If you're reading this, you've probably already had or are trying to avoid the 'wrong part' headache. Here's my checklist (which has caught 47 potential errors in the past 18 months, after I started tracking):

1. Step 1: Compare the part number against the hoist's nameplate, not just the model name. A 'PK-5' from 1998 vs. 2003 might use a different gear set.
2. Step 2: Ask for a drawing or dimension sheet. A competent supplier will provide a basic outline or a digital photo of the original part with measurements. If they say 'trust us, it fits,' ask for more details. (Let me rephrase that: if they can't send a photo, proceed with caution.)
3. Step 3: Check for a 'cross-reference' guide or a list of superseded part numbers. Demag parts often have a 'new number' replacing an 'old number.' The failure to check this is how I ended up with 15 useless motors.

A quick pricing reality check: Based on publicly listed prices from major online Crane parts suppliers (January 2025):

• A replacement hoist motor (0.5-2kW range, standard duty): $400-$800.
• A complete hoist (1-ton capacity): $1,500-$3,000.
• But setup fees for a custom adaptor plate or a non-stock part run $50-$150. Rush shipping adds 25-50%.
• Prices exclude shipping; verify current rates.

Q6: Any last advice? What should I avoid?

The biggest mistake I see: treating a parts list like a menu. Just because a part number exists doesn't mean it's the right one for your hoist. And just because a part is 'compatible' doesn't mean it's plug-and-play.

I've learned to embrace the 'I don't know' moment. It's better to send an email asking 'Is this part a direct replacement for my 2005 Demag DK-5?' than to waste $3,200 finding out it isn't. The vendor who replies 'I need a serial number to tell you'—that's the one you want to work with.

The most frustrating part: the same issues recur despite clear communication. You'd think written specs would prevent misunderstandings, but interpretation varies wildly. After the third late delivery from a supplier who 'guaranteed fit,' I was ready to give up on them entirely. What finally helped was building in one extra day for a verification check—not trusting their estimates.
