The task for the crane was to remove the machine, which is used to separate wood, metal and paper, from a low-loader between system sections already installed, and then move it to the end of a corridor, turning it around 90 degrees in a confined area.
Crane schedulers at Grohmann GmbH in Berlin ordered the new three-axle 55t compact crane to perform in a restricted space in the hall in the north of the capital.
After crane driver Thomas Anke had positioned and erected the machine, there was barely an inch of space to spare between the counterweight and the wall of the rack unit when the superstructure was slewed.
Once the LTC 1055-3.1 had removed the 8t sorting machine from the low-loader, the trickiest phase of the hoisting operation began. To manoeuvre the recycling equipment around the corner beneath a 10m-high metal rail, Anke first telescoped the crane boom to a length of 10.5m. The blower separation unit was then moved around the corner. Next, the telescopic boom was extended again with a gross load of 9.5t on its hook. Finally, at a radius of 12m, the crane positioned the sorting machine in the plant.
