Based on the first sets of Technic lego®, this mobile crane truck was build. The crane itself is a copy of the 855 set, although some modifications were necessary to provide that the boom could be lowered without hitting the drivers cabin.
The outriggers can be extended (left and right independent) by turning the ‘bush’ wheels at the rear side of the truck.
It's just a very simple model (755 parts), and is easy to make.
Remark: When rebuilding you will notice that the model could be made much better (colour wise and brick wise). I decide to leave the model as it was in 1982, based on the available bricks which I had at that time.
