Basic
- Use 4"x4" square tubing, 3/16" to 1/2" wall thickness
- CNC torch holes, typically 1"
- Plates are 1/2" thick
- Holes can serve as holes for pins or bolts
- Plates are in sizes that are multiples of 4"x4"
- For heavy duty joints, 3" pins are used
- 3" holes are reinforced with DOM Tubing for precision of fit
- Bolt-together XYZ corners are a basic design pattern
Details
- Plates may be stacked
- Tubes may be stacked
- Rotating joints are a key motion feature
- Machines may be scaled from sub-ton to 50 ton weight
Calculations
- 3" pivots can be designed for 150 tons of force at the pivot
