4x4 PTO Driven Timber Trailer BUILD Ep.6 - Hydraulic Crane

4x4 PTO driven timber trailer build continues. This time I'm welding on the CNC laser cut base plate with locating pin for the hydraulic crane. Since the trailer I'm building is taller than the trailer needed for the crane I had to modify the side stabilizer mount plates as well. So I just drew up needed parts in FreeCAD and cut'em out on the homemade CNC plasma table. With these CNC cut parts I made the stabilizer mounts also taller by just welding the homemade parts on to the provided mounts. I'm also mocking up the drive shaft. In the process of filming this video I managed to install and uninstall this crane at least 6 times. :) To be continued. Stay tuned for the next episode & thanks for watching!
