Backhoe/Research Development

Status

There was a version of the backhoe for the LifeTrac 1. In 2012, OSE started a redesign. The new backhoe will have an increased range of motion and use the Bobcat quick attach standard to attach to the LifeTrac 6.

Redesign Status

For Oct 2013 work:

• Dan Log, Cody Log, and Marcin Log.
• Development Board
• The main open issue is redesigning the main pivot so that we have somewhere to mount the hydraulics to get as close to 180 degrees of side to side movement.
• Another known task is adding bushings to all 1" pivots since they have too much slack.

For the 2012 work (most of which is still being used):

• Lenny-Wayne as as Guest Collaborative Production Director was working on the GrabCAD Backhoe Redesign for Fabrication with Aaron as project manager.
• Brian Log.
• Backhoe Log.
• http://opensourceecology.org/wiki/GrabCAD_Backhoe_Redesign_for_Fabrication

Designs

• Oct 2013 redesign is using File:Backhoe deep dig.skp.
• This is probably the previous version: Backhoe Github Repository. We'll update this after the Oct 2013 redesign.
• Prototype 2: File:Backhoevari.zip. You'll need the VariCAD viewer. To manipulate the 3D object, press 'Ctrl+Shift+C' and left-click to move it around in 3D.

Existing Designs

• Oily Hands has a huge list of diggers people have built themselves
• this guy has a fully documented build process for his
• Ubuildit Plans has a backhoe design that's about as simple as one can possibly get.
