The backhoe attached to the front of the LifeTrac I.


The Backhoe is a piece of excavating equipment used for digging holes and trenches.

This is probably an old version. We'll update this after Oct 2013 redesign.

They are typically mounted on the back of a tractor or front loader, this one is mounted on a LifeTrac. It consists of a digging bucket on the end of a two-part articulated arm. The section of the arm closest to the vehicle is known as the boom, and the section which carries the bucket is known as the dipper or dipperstick (the terms "boom" and "dipper" having been used previously on steam shovels). The boom is attached to the vehicle through a pivot known as the kingpost, which allows the arm to slew left and right, usually through a total of around 200 degrees. Modern backhoes are powered by hydraulics.

The backhoe is one of the most basic dirt working tools and is a common attachment to many small tractor and skid-steer vehicles. It can be used for digging trenches for foundations, digging up material to make compressed earth blocks, digging waste pits, and many other common building/farming tasks. Furthermore, by attaching a chain to the bucket, the backhoe can be used to lift and transport heavy loads such as engine blocks, battery packs, long pieces of pipe, etc.

Commercially manufactured backhoes vary greatly in their size and capabilities and therefore vary significantly in price. A quick google search seems to indicate that relatively small, simple devices like the one we are considering range from 2 to 4 thousand dollars with more sophisticated attachments approaching 10 thousand dollars.

TODO move this link to development board: Previous and still relevant research is at Backhoe/Research_Development.

As of Oct 6, 2013, we're finishing the redesign and building it:

  • For Oct 2013 work logs, see Dan Log, Cody Log, and Marcin Log.
  • [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):
