This system uses the four crane cameras to show a computer-assisted diagram of the possible outreach of the outriggers, as well as the counterweight tail-swing radius at the crane’s current location. Once at the worksite, the new Demag Surround View makes it easier for the operator to position the AC 80-4.

“Even when staying under an axle load limit of 10 t, it can carry 3.3 t of counterweight.” Demag Surround View system On the road, it can transport up to 9.3 t of this counterweight itself while remaining under a 12 t-axle load limit, and all while also carrying the 6.5-m swing-away jib, said Demag. The AC 80-4 has a sophisticated counterweight design, which makes it possible to have a maximum counterweight of 17.7 t. “Together with its width of only 2.55 m, our AC 80-4 is better suited for tight work sites than any other crane in its class,” said Mr Klein. The crane’s total length is 12.15 m, the carrier length is 10.60 m, its height does not exceed 3.85 m, and the front overhang is a modest 1.49 m. The AC 80-4 features a compact design, with nearly all of its dimensions being shorter than those of other four-axle units in its class, revealed Demag. That’s why we decided to add the AC 80-4 to our product portfolio in the segment of up to 100 t,” explained Michael Klein, Demag product marketing manager. In fact, a large number of customers kept confirming this time and time again. “The worldwide success that this model had, showed that there’s significant interest in a crane with this kind of lifting capacity. “At a radius of 10 m, it can lift 9.7 t, which is 2.2 t more than the next most powerful competitor.” The crane features a line pull of 66.9 kN.ĭemag already had an 80-t crane, the AC 80-2. The manufacturer said the AC 80-4 also raises the bar with its main boom extended to 50 m.

The crane can lift an impressive 5.4 t at a radius of 14 m. In the class of up to 100 t, no other crane comes close to the AC 80-4’s lifting capacity with a fully extended boom up to a radius of 30 m, according to Demag. The main boom can be lowered up to 3° below its horizontal position so that potential work at height can be easily eliminated and the jibs can be installed quickly and safely. Accordingly, the crane is also recommended for indoor projects. In addition, a 1.50-m runner with a capacity of 26.6 t is available for the Demag AC 80-4. “Its capacity is a generous 23.8 t, meaning it can be used to lift heavy loads over obstacles,” said Demag. If the main boom length is not enough, the reach can be extended with a 6.5‑m extension that can be offset by 25° and 50°.
