Crate Cart
Designing a DIY farm cart.Background
Design requirements:
- Accommodate some typical crate sizes, e.g. 24" x 20" x 11" and 23" x 7" x 15" Nursery Crate;
- Allow for 2 x 2 or 2 x 4 stacking of crates;
- Wheel base should straddle 30" beds
- Use recycled bicycle wheels
- Improve on use of Vermont Cart:
Initial Design
 |
|---|
| Carrying area of planned 'crate cart' is 44" x 54". |
Design notes / ideas:
- Because cart will be lighter-weight than Vermont cart, and wheel must be mounted further forward, consider shifting 'back bumper' forward so that center of rear-placed crate is over wheel center
- Accommodate different recycled wheel widths by using a 'brace' and shifting two halves of frame with respect to eachother within the brace

Notes on initial prototype:
- make a handle that can allow for 'stepping inside' and lifting straight-arm while walking forward
- possible use of u-bolts to reduce number of drilled holes

Going to revert to drilling for the cratecart; farmers are capable of it, greatly reduces the cost; and less dependent on particular supply chain around ubolts.
Need to depict the dimensions.
