Wiesbauer’s Terex Demag AC 700 in a tandem lift

Wiesbauer has updated its range of large cranes with a new Terex Demag AC 700. The crane was fully-equipped upon delivery and included a 160t counterweight, a Sideways Superlift (SSL), a main boom extension of up to 36 meters, a rigid fly jib of up to 50 meters, and a luffing fly jib with a length of up to 96 meters.

The Terex Demag AC 700 was selected, according to Wiesbauer, because it is currently the most powerful telescopic boom mobile crane approved for road travel. Additional factors leading to its selection included the AC 700’s outstanding load capacities and its simple and quick handling.

Wiesbauer handles jobs all over Germany and in bordering countries. The crane specialist has relied for years on products from Zweibrücken-based Terex Demag for its largest capacity cranes. The first crane in Germany with a 650-ton lifting capacity was delivered to Wiesbauer in 1999. That model was an AC 650 with SL-bracing. The recently delivered AC 700 is Wiesbauer’s fourth in this crane class.

First application – Transfer work via tandem lift

For its debut mission, the new AC700 travelled directly from the factory at Zweibrücken to the wharf for heavy loads at the Port of Heilbronn. There, five MAN marine engines were transferred to a cargo ship by means of a tandem lift with a second AC 700. Each engine weighed 225 tons.

Marco Wilhelm, technical field service, commented on the job: “What is unusual about this transfer is that, with this number of motors involved, the crane must be moved through ballasting and be re-positioned several times in order to move the engines from the back to the front area of the wharf. Because of this, both 700-tonners were equipped with short telescoped booms, as well as a 100-ton part ballast.”

Wiesbauer, founded in 1958, has 45 cranes currently in service, with telescopic-boom cranes from 30t to 700t capacity and lattice-boom cranes up to 800t capacity. In 2005, Jochen and Thomas Wiesbauer took over the company’s management, thus bringing it into its third generation. The company provides transport and assembly services as well.
