Liebherr LR 11000 - Emil Egger
Emil Egger from St. Gallen (CH) took in 2017 this sharp Liebherr LR 11000 into operation. It is until today stil the largest crane in Switzerland with a lifting capacity of 1,000 tonnes. The second job for the crane was in Oberriet (CH) where the crane was supporting on the construction of a new concrete plant.
The undercarriage is 12.44 meters long and 11.2 meters wide.
Between the tracks is in total 50 tonnes of central counterweight installed, each side 25 tonnes (counterweight frame of 5 tonnes and two 10-tonne slabs). By jobs with longer main boom is the central counterweight increased to 90 tonnes.
The crane is powered by a 680 hp strong Liebherr V8 diesel engine.
The tracks are 12.44 meters long, 2 meters wide and 2.5 meters high. A single track weight with track plates 60 tonnes.
The crane is equipped with two 23-tonne hoist winches with each a 23 mm hoist cable.
The counterweight exists out of two consoles with each 5 tonnes and on both sides a stack with eigth slabs each 10 tonnes. In total 170 tonnes with a tailswing of 9.57 meters. The maximum counterweight is 250 tonnes.
The crane stood here erected in SL configuration; a tapered main boom. In this configuration has the main boom a minimum length of 18 meters and a maximum length of 114 meters. Here is the main boom 54 meters long, in this configuration is the crane able to lift 556 tonnes on a 9 meter radius and 56.8 tonnes on a 48 meter radius, but only in case the correct amount of reefings and counterweight is used.
A very impressive crane that already had some heavy jobs in Switzerland and Germany in the meantime!
