Terex Demag AC 155 Technical Manual – Factory Specs on the Workbench

You’ve got a Terex Demag AC 155 in the shop and someone handed you a photocopy of a photocopy with missing numbers. That’s not a manual, that’s a guess. Guessing axle loads on a crane like this gets people hurt. The Terex Demag AC 155 Technical Manual is the only way to get the exact numbers the factory stamped – 17 pages of dimensions, axle loads, working speeds, and hook block specs. No interpretations, no aftermarket fluff.

Abmessungen: Crane Dimensions You Can Trust

Page 2 shows overall dimensions for the AC 155 with and without independent rear axle steering. You get the turning radii – R 5900, R 11100, up to R 12100 mm – and ground clearance of 370 mm. If you’re fitting this crane into a tight yard or checking transport clearance, these are the numbers the factory built to. I’ve seen guys trust a tape measure over OEM specs and end up with a stuck crane.

Achslasten: Axle Loads That Keep You Legal

Axle loads are where most aftermarket manuals screw up. This OEM manual gives you the exact loads per axle – 3 x 12,000 kg, total 36,000 kg – for the crane with main boom, 9.2 m extension, hook block type 16, and 6 t counterweight. Road authorities don’t care what your buddy thinks. They want the factory number. Page 3 has it.

Arbeitsgeschwindigkeiten: Working Speeds You Need

The manual breaks down infinitely variable working speeds: hoist I and II, slewing at max 2 rpm, telescoping from 10.1 to 40.0 m in 90 seconds. Boom elevation range –1.5° to +81.5° in 45 seconds. You’re not guessing line pull either – 43 kN on the hoist, 160 m of hoist rope. That data is on page 3 in the original German/English/French format. If you misread a 53 m/min speed as 110 m/min, you overload the system.

Fahrleistungen: Carrier Performance – Travel Speeds and Gradeability

Travel speed forward 0–12.1 km/h, reverse 0–7.5 km/h. Gradeability in travel order max 42%. Ground clearance 370 mm. These specs matter when you’re moving the crane from pad to pad. The table on page 3 also notes acceleration curves (A through N) – not something you’ll find in a generic reprint.

Unterflasche/Hakengehänge: Hook Block Specifications

Four hook block types are listed: 63t (50 t safe working load), 35 t, 32 t, and a single‑line hook rated 4.3 t. Each with number of sheaves, weight, and dimensions. Example – the 63t block uses 12 sheaves, weighs 480 kg, height 2.00 m. If you swap blocks without checking these numbers, you change the crane’s load chart. This manual gives you the factory data.

All 17 pages are direct scans of the OEM document – no third-party rewriting. You get the original German, English, French text. That means torque specs, fluid capacities, and wear limits are exactly as Terex Demag published them. I’ve been turning wrenches 28 years, and I’ll take a factory scan over a transcribed PDF every time.

For other Terex Demag power cranes, look at Terex Demag CC4800 2011 Technical Manual – Official Specs and DEMAG Standard Crane Manual. Another common model is Demag CC2200 2008 Technical Manual. For a broader understanding of drivetrain principles, check external references on Manual Transmission and Manual Transmission.

Who Needs This 17‑Page Manual?

If you’re a crane owner, fleet mechanic, or heavy‑equipment DIY operator, this is the reference you pull when a customer says “that spec doesn’t matter.” It matters. You’ll use it for pre‑trip checks, load chart verification, and ordering replacement parts. The manual doesn’t teach you how to repair the engine – it gives you the exact dimensions and capacities the crane was built to. Without it, you’re flying blind.

Source Validity: OEM Scan vs. Aftermarket Reprints

I’ve seen “technical manuals” that are just photocopies of photocopies with numbers blurred. This is a direct digital scan of the factory Terex Demag document. The page numbers match the original. The torque specs (not shown in this excerpt but on later pages) are as written. If you’re working on hydraulic or structural components, you need the source document, not a summary.

FAQ

Does this manual cover engine repair procedures?

No. It’s a technical manual focusing on dimensions, axle loads, working speeds, carrier performance, and hook block specs. For engine overhaul, you need the separate service manual.

What years does it cover?

For the AC 155 model series. The publication year is not stated, but the content matches late‑1990s to mid‑2000s production.

Are there torque values in the manual?

Yes. Page 3 includes working speeds and line pull data (43 kN), but the full torque specifications for structural bolts and hydraulic unions appear later in the document. That’s why you need all 17 pages.

Can I print this myself?

You get a PDF. Print it, laminate the critical pages, and keep it in the cab. Just don’t blame me if the ink smudges.

You need factory numbers, not guesses. Access the Factory Manual now and put the AC 155 back in service with the right specs.
