This is a part designed for the LGB heavy load car number 40580. I had the middle part (bought from spares when LGB went bancrupt) but not the front and rear bogie frame work of the car, so I decided to create them. LGB trucks and axels will fit the frames. When I get time I will also design the bogies and the middle part so you can create a complete heavy load car. Mine is already running on our layout (see picture with tank). The complete file is just for reference. Enjoy!
2016-09-30: I've added bogies and wheels (also LGB wheel will fit). You will need 4 pcs of 70mm long steel shafts, 3mm in diameter. The bogies are glued together. Use the mounting help to get the correct distances. Put the mounting help on the table, insert the shaft, add the first wheel, insert "wheel_middle", add the second wheel and remove the mounting help. You need to drill all holes in correct 3mm diameter. I've also corrected a small misstake I made in the frame model. The new complete file also includes the bogies.
