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 first job of this crane was in Zürich (CH) to instal precast concrete elements up to 90 tonnes onto a radius of 70 meters. The undercarriage is 12.44 meters long and 11.2 meters wide. Large enough to position a container between the tracks.

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 powered by a 680 hp strong Liebherr V8 diesel engine.

The counterweight exists out of two consoles with each 5 tonnes and on both sides a stack with ten slabs each 10 tonnes. In total 210 tonnes with a tailswing of 9.57 meters. The maximum counterweight is 250 tonnes.

Attached to the derrick boom is the center piece of the VarioTray with another 120 tonnes of counterweight.

The rest of the VarioTray stood within slewing range with another 240 tonnes. The maximum derrick counterweight is 450 tonnes on a counter radius of 12 to 22.2 meters.

The center part of the crane weights 60 tonnes, both tracks with each 60 tonnes are attached to the center part. The superstructre weights including A-frame 77 tonnes but can be splited for a more economical transport to 45 tonnes.

The derrick boom has a 36 meter length, but can be extended to erect longer main booms to 42 meters.

The crane was erected here with a 42 meter main boom and a 54 meter luffing jib. On moments where the crane wasn't used it was required to park the luffing jib at the ground to avoid obstructions for the tower cranes at the same construction site.

A very impressive crane that already had some heavy jobs in Switzerland and Germany in the meantime!
