First job for Swiss LTM11200

The first lift for Senn’s new 1,200 tonne Liebherr LTM11200-9.1 All Terrain crane was carried out in mid June, at a wind farm in the Jura mountains.

There are a total of eight wind turbines to be installed on Mont Crosin a perfect task for a big telescopic.

The first blade is lifted into place

In order to install the Vestas 2MW systems at a hub height of 85 metres, the crane needed to lift 80 tonnes to a hook height of 113 metres. The LTM 11200-9.1 was therefore rigged with 182 tonnes of ballast, 52 metres of telescopic boom and Y-guying system, a 20 metre lattice extension and 48 metre luffing jib.

Senn co-owner Jörg Senn said: “It only took a few days for us to be able to do what we wanted with the crane. It can be set up and dismantled very quickly, and even with these systems it still had lifting power in reserve.“

The mast goes up in the Jura mountains

“The crane only needs a small area to be assembled and erected, and that is particularly important in areas such as here in the Jura where nature can be extremely sensitive”.

Senn ordered the world’s largest telescopic crane specifically for wind power installations, as it grows in importance in Switzerland.
