Terex Demag AC100/4 Technical Manual – Factory Specifications for All-Terrain Cranes

Working on a 100-ton capacity all-terrain crane means one wrong dimension on the boom extension or counterweight can drop a load – or drop the crane. I’ve seen guys trust aftermarket spec sheets and end up with the outriggers in the wrong hole pattern. The Terex Demag AC100/4 Technical Manual is the 40-page factory document that kills the guesswork. It gives you the actual measurements, not some third-party approximation.

HA Main Boom and HAV Folding Jib Dimensions

The manual opens with page 4 showing overall dimensions – width at 2.55 m on 16.00 R 25 tires, overall length, transport height. Page 8 dives into the HA main boom sections, including the folding swing-away jib (HAV) starting on page 13. You get the exact lengths for each boom section and the jib angle limits. If you’ve ever tried to extend the main boom without knowing the clearances around power lines or building overhangs, you know why this data matters.

Does the Manual Cover Counterweight Configurations?

Yes. Page 7 lists counterweight options: 6.9 t within 12 t axle load, 21.3 t within 16 t axle load – roadable. The manual doesn’t just give numbers; it shows how to position the counterweight plates for each configuration. That is the difference between a stable lift and a lawsuit.

Factory Spec Data vs. Aftermarket Compilations

I won’t mince words: aftermarket crane manuals are dangerous. They take one PDF from a used machine, copy the pages, and sell them with typos in the torque values. This Terex Demag original has the factory stamp. The table on page 5 gives engine output, transmission ratios, and axle loads. Manual Transmission is a good read for understanding gearbox theory, but for the AC100/4 you need the original – not a reprint.

Boom Extension Systems: HAV-VA Variable with Swing-Away Jib

Page 18 covers the HAV-VA variable extension with swing-away jib – the most flexible boom setup in its class. The manual shows the assembly sequence and the locking pin torque requirements. Torque specs are listed in Nm. If you’re in North America using ft-lb, convert with caution; the manual uses metric. Skip this step and you’ll shear pins.

40 Pages of Factory Documentation – No Fluff

You get exactly 40 pages. Not 400 pages of filler. Sections include: Dimensions (4), Specifications (5), Equipment (6), Counterweight (7), HA Main Boom (8), HAV Folding Jib (13), HAV-VA Variable Extension (18), Basic Equipment & Options (26), MS Runner (23). Every page is a direct scan from the OEM. Terex Demag CC4800 2011 Technical Manual – Official Specs covers a larger lattice-boom crawler; the AC100/4 is a different machine entirely – this manual is specific.

Real-World Use Case: Setting Up on a Construction Site

A DIY crane owner – yes, some people own these as investments – needs the outrigger base dimensions from page 4 to lay out the pads. The manual lists the four outrigger bases (serial equipment) and their spread. Without that, your crane might boom over an unrated pad. For technicians billing by the hour, the manual cuts the search time to minutes. No flipping through three different PDFs.
