    Liebherr LR 11000

    I uploaded some WIP photos. LIebherr LR 11000 WIP by Dawid Szmandra, on Flickr LIebherr LR 11000 WIP by Dawid Szmandra, on Flickr Here you can see the LEGO turntable, which is only used to rotating and XY positioning. I initially wanted to use 4 PF Medium motors for the drive of tracks, but changed them into two EV3 Medium motors. LIebherr LR 11000 WIP by Dawid Szmandra, on Flickr Here is "core" which is connected with superstructure and bottom ring with minifigure heads. I used grease so this is not 100% LEGO in true. LIebherr LR 11000 WIP by Dawid Szmandra, on Flickr Upper ring with heads. Yellow part is placed on that. Thanks to two rings, the bearing can carry torque, not only vertical force.

LIebherr LR 11000 WIP by Dawid Szmandra, on Flickr Sensor for force measurement, range 0-5kg. It allows the measurement of total crane load (just a simple dynamometer).

    Track construction is almost identical as here: I did not have any problems with them.
