FEED SPECIFICATIONS:
per discussion with a knowledgeable experienced BLM/Tube bending personnel :
to Mandrell Feed you are LIMITED TO the 156″.
But there is NO Limit on HITCH FEEDING – you can feed a 6′ to 7″ feet per stroke until you run out of material. The is also FREE BENDING without the Mandrell.
The only issue is radius that are to tight will collapse the tube wall.
If you wanted to bend a 20′ or 240″ 3″ tube it will all depend on the clearances as the part moves forward. Many times manufacturers my place the tube bender on large I-Beams to increase the work envelop, by raising the tube bender up.
