Terex AC 350/6

Krandienst Lange in Germany used its Terex AC 350/6 wheeled mobile telescopic crane to assist in the dismantling of an old power plant.

A pair of overhead travelling cranes were dismantled at the plant in Lubmin, near the town of Greifswald. Torsten Lange, Krandienst Lange director, selected the newest crane in the company's fleet, a 350 tonne capacity Terex AC 350/6. A 200 tonne capacity AC 200-1 was also on site to support the larger crane on what was its first "real" job at a construction site.

"The crane passed with flying colours," said Torsten Lange. He and crane operator Guido Siegmeier were pleased with the way the assignment went. The 125 and 25 tonne capacity gantry cranes were dismantled in a tandem lift operation over 2 and half days.

For the job the crane was rigged with 31.7 m of main boom, a 4 m adapter and 22 m luffing jib (SWIHI configuration). The luffing jib was needed to lift the load out of the building at a travelling height of 30 m, above a high projecting edge.

"Since I don't get work for a 350 tonne class crane every day, it is particularly important for the crane to be able to handle a wide range of operations," explained Torsten Lange. "The AC 350/6 is an all-rounder that I can use efficiently even for operations suited to the 160 tonne class by using a partial counterweight. For tasks that require a 350 tonne class crane, I need only very little additional transport capacity and can have the crane ready-to-operate on site in no time."

Operating since 1997, Krandienst Lange's fleet includes mobile cranes, lowbed trailers, and loader cranes. It operates mainly in Mecklenburg-Western Pomerania but has extended to construction sites in other regions and abroad.

To boost utilisation, the AC 350/6 has been optimised to cover the greatest possible range of operations in the 160 to 350 tonne class, Terex said. It was originally designated AC 300 but its capacity, especially with fixed jibs, was sufficient to warrant an increase, Terex said. A free update will be available for machines already delivered.
