This crawler crane is made from the 42055 excavator. The main beam has a modular design and can be extended.
Main features:
-Modular main beam
-Motorized lifting
-Motorized raise-lower of main beam
-Motorized forward-backward movements
-Manual turning of crane (needs to be improved)
During final constructions the following flaws were found :-(
-When the gearbox is not in main beam raise-lower position the beam will go down. To solve this a stopper pin is added (so to raise-lower the beam the pin needs to be removed).
-When the main beam is lowered the model might tip over (need to redistribute the weight of the top part).
