We've just sent off our first 53ft long portable sawmill to the US. This machine was commissioned to saw extremely long crane pads.
We are looking forward to video footage of this beast sawing in action. A little hard for us to source such long logs to test it out on!
You will note that this machine is still all operated from one end. You also have 180 degrees access to load your logs and remove your beams. Maybe 2 forklifts could be required? A major advantage of a sawmill of this length is its accessibility.
