Backhoe Conceptual Specifications

• Based on 4x4 inch tubing, 1/4" or 1/2" wall depending on strength required
• Scaling can happen by:
  • Extension of tube members inlength
  • By stacking tube members on top of each other in one direction
  • By stacking tube members on top of each other in two directions
  • By stacking tube members in a space frame configuration by using connector plates.
  • Using thicker wall of tubing
  • May be connected to one another by plates
  • Stacking of connector plates for increasing strength
  • Stacking of pivot joints plates to increase pivot strength
• Pivot joints are used to couple tubing members

Ecology

• Same technique for creating articulated joints may be applied to creating loader arms or cherrypicker arms
• Similar technique may be used to build well drilling rig frames
• Similar technique is used to build the ironworker machine.
