Hi, As I really like the design and HUGE size of this crane I wanted to build it. The LDD was great to use and a good help during the build.
As I experienced the same issues with the gears skippings and slow movement I decided to rebuild the gearbox, but still remain within the original design and keep it a true C-model
The results:
The gears stay in place due to direct motor mount and reinforced structure holding the gears. Also moved some of the gearing down to the crane house, removing the forces away from the gearbox driveline.
The release handle for the containers is changed to manual, as it's light and only requires 90 degrees movement of the lever..
The propulsion handle works only one direction, but as the direction switch on the battery box can be used now to change motor direction the crane is driving both ways.
The other gears, made reinforcements to keep them in place and moved the angled axles out.
And the changes in the cranehouse:
Also changed the locking of the gearbox top the cranehouse by removing the 4m axles and replacing them with 3m beams with 3L connector pins
The top of the boom I used Pleegwats' modification adding the other wheels:
Here's the link to the modified LDD file https://bricksafe.com/files/Skeltertje/Luffing-Crane_42055-C Model_v2.lxf
I checked the 4205 A model part list which I pulled from an other LDD file and all the parts used for the crande are also in the original set,
I guess this means the crane remains a true C model..
Again, I really liked your design Leonard and after the modifications done now it also is fun playing with it!
