Introducing the Lego Technic Crawler Crane Track Chassis. Build a Crawler Crane Pt.4
BUILD YOUR OWN CRANE VIDEO: https://www.youtube.com/watch?v=Cmpx7IuXtmg
This is the 3rd Track chassis that I have developed over the past few years for my larger and larger Crawler Cranes. Key to the design is the reduction in twist, distribution of weight from the frame into the tracks and rotation of the frame around the center moment of the tracks.
The Track chassis is designed to fit perfectly into my crawler crane. You can find that design files here - https://rebrickable.com/mocs/MOC-22859/HRU%20Bricks/moc-crawler-crane/#comments
**NOTE: Long term storage of any Lego Technic build that has a consistent load on it will warp the beams over time. Note in the physical build picture I have added up right supports for long term storage and display.
Inside the digital design files (Stud.io and LDD) you will find that the LDD has the frame in sub models which are not to hard to build from and the Stud.io file can be used to buy parts with.
The files have been uploaded to Brick safe and the link is attached to this page. If you have any issues or thoughts on the build message me below.
