A Further LR 1250 Enhances Crane Fleet and Convinces During Works Expansion

1,144

To date fifty-two telescopic and crawler cranes with lifting capacities up to 500 t as well as various loading and mobile construction cranes made up the fleet of the company Dornseiff Autokrane und Schwertransporte & Co. KG, which operates from four locations in Germany. Now the crane hire company has extended its fleet with an additional fully equipped crawler crane, type LR 1250, from Liebherr.

The lighting manufacturer Osram Opto Semiconductors GmbH is also expanding, its facilities in Regensburg are being considerably enlarged. The company Dornseiff is involved in the project with its new LR 1250.

For this jobsite the Liebherr crawler crane was fitted with a 35 m main boom and a 35 m jib. It was used for lifting heavy concrete elements as well as the steel construction of the new production building’s roof structure. The crane’s Blocked Crawler Mode was deployed several times. At an outreach of 45 m, the lifting capacity could thus be increased by 20% to 18 t, and at 36 m by 15% to 23 t. This significant improvement made it possible for Dornseiff to accept the contract for this jobsite.

Thanks to the increase in lifting capacity in Blocked Crawler Mode, it was not necessary to use the next biggest size of crane – a decisive advantage due to the confined space on site. Furthermore, the continuously variable main boom with lifting capacities that are actively calculated by the control system proved to be highly efficient for this jobsite.
