Hello all,
today I found an easy way to increase the lift capacity to more than 500 grams. I just turned the rear supports to front to support the front supports and connect the T-pieces of the rear stands to the L-pieces of the front supports. Adding the now free 1x3 liftarms to these conections improves the stability, so that the crane is able to carry about 650 grams, thought then the higher part of the crane arm bends extremely. I also explained this easy task in German in this thread: https://www.1000steine.de/de/gemeinschaft/forum/?entry=1&id=427774#id427774
There you can also find three additional pictures. Thank you for reading and greetings from Lower Saxonia, André (Plastik)
