Liebherr LR 1200
Van der Meijden
This fine Liebherr LR 1200 belongs to Van der Meijden from Koudekerk aan den Rijn (NL) and was deployed in 2009 during the construction of a new museum in Opmeer (NL). It is a 220-tonne crawler crane.
The crane is powered by a Liebherr D 936 L A6, a 10.5-litre 6-cylinder diesel engine with an output of 270 kW (362 hp).
The carrier is 8.7 metres long and 7 metres wide. For transport on public roads, the crawler tracks have to be separated from the body; the crawler tracks weigh 19.8 tonnes each.
A total of 81 tonnes of ballast is mounted on the superstructure; the ballast consists of two wide base plates of 14 and 16 tonnes. On top of these, ten blocks of 5.1 tonnes each are mounted. The ballast has a swing radius of 6.2 metres.
A total of 36 tonnes of central ballast is mounted on the carrier.
Here, the crane was erected with a 29-metre main boom and a 38-metre luffing jib and was deployed to erect prefabricated concrete elements.
The luffing jib has a base length of 20 metres and a maximum length of 95 metres.
At the same construction site, a Liebherr LR 1300 of Van Marwijk was also deployed. A very fine operation for both crawler cranes!
