The is the main page for version 4 of the Backhoe. See that page for general info and how it fits into the GVCS.

Status[edit]

As of Oct 2013, there is no backhoe 4, nor any concrete plan for one. This page is here as a place to collect ideas for the next version of the backhoe if or when someone works on it.

Ideas for Backhoe 4[edit]

  • Jeffery Stump suggests: If anyone revisits the design later, they should consider putting the cylinder that moves the boom below, so that it can work in compression. That would make it 21% stronger for the same moment arm. I'm pretty sure the current set up will make a decent back-hoe, since the analysis I'm doing now is pretty conservative, but you should definitely use the larger piston, at least for the boom actuator. If I adjust the 1000 lb bucket load down to 695 for a load of heavy sand that completely fills the bucket I get that the bigger cylinder will work for extensions less than 55 inches. I updated a few pages of my calculations to make them more reader friendly. Probably at some point we should work out a consistent format for how calculations should be demonstrated and explained. Once again, the geometry section is unfinished: https://docs.google.com/file/d/0BzK1bz3_JbWNUDdUazRDRzNIZkU/edit?usp=sharing
