A Liebherr LTC 1050-3.1 mobile crane installed a gantry crane at the production hall of a company that manufactures models and moulds, in Biedenkopf in the state of Hesse, Germany.
The crane, operated by Gummersbach-based crane contractor Ley, was presented with some challenges, in that there was little space to extend the supports and hardly enough height for hoisting work.
The crane assembly was possible between the fixed workstations as a result of the mobile crane’s VarioBase variable supporting system. A support strut on the opposite side to the load could only be extended to 39%.
The main gantry, which also had a railing, had to be placed on the crane track just under the roof of the assembly building at a height of around 10m. It was only possible to work in these conditions using the heavy duty jib lowered to 60% and the hook traverse. In this configuration, the hook was just under the crane height and the compact crane had to operate with very little space above it. Operator Yves Chomsé elevated his cabin several metres in the air to get closer to the action
