Liebherr LR 1350/1-LN - Max Bögl
This is the other Liebherr LR 1350/1 of Max Bögl, this one is in the LN version. LN isn't an abbrevation but stands for the types of main boom and luffing jib, with them the crane is executed.
The big difference between the normal and the LN crane is the boom, the boom of the LN is much smaller and lighter. The main boom of the normal crane measures 3 x 2.4 meters, that one of the LN version 2.42 x 2.2 meters.
Fitted with 105 tonnes of counterweight. That isn't maximum, maximum are 125 tonnes. The tailswing of the counterweight is 7.1 meters.
The crane is powered by a 6 cylinder Liebherr D 926 TI-E diesel engine with 367 hp. With them are four hydraulic pumps for the crane functions driven.
The crane's year of manufacture is 2008.
The tracks are 9.7 meters long, 1 meter wide and 1.53 meters height. The tracks have a mass of 22 tonnes each. The undercarriage is 8.2 meters wide.
Between the tracks is hanging in total 38 tonnes of central counterweight. The counterweight per side exists out of two slabs with a 7.5 tonnes mass and a 4 tonne plate on top, that is used as walkway at the same time.
The LN boom is smaller and lighter, that means less loose of capacity due the mass of the heavy boom on larger radii. It is also possible the work with longer boom lengths. For example main boom with luffing jib; normal LR 1350/1: 56 + 66 meters and the LR 1350/1-LN: 66 + 84 meters.
The A-frames are closed profiles instead of the lattice A-frames of the normal LR 1350/1. Over the main boom of the LN crane is is possible to lift 250 tonnes maximum.
Fitted with 24 meters of main boom and a 36 meter luffing jib.
