A two-wheel cart is a bed on one axle with two wheels and a pair of shafts, and it is the simplest wheeled vehicle to build because it needs no steering gear and copes with rough ground. One horse pulling it on a decent road can move about 500 kg, 20 times what a person carries comfortably on foot (25 kg), and the cart can be built in a few days with basic tools.
Part of Cart & Wagon Construction
A two-wheel cart is a load-carrying bed on a single axle, pulled by one animal through a pair of shafts, with the animal bearing a small part of the load.
One Axle Means No Steering Problem
A vehicle with two axles needs a way to turn the front one. A cart with one axle simply pivots on it, so the animal can turn it on the spot and the builder has no steering to make or break. The same single axle makes it light enough for rough tracks. The multiplier is large: 500 kg / 25 kg is 20 times what one person carries.
What A Cart Is Made Of
- Bed: a rectangular frame of cross-members with a plank or pole floor
- Shafts: two long poles, the full length of the cart, extending forward to the animal
- Axle: the beam under the bed that carries the wheels (Wooden Axle Construction or Salvaged Metal Axles)
- Wheels: two, solid discs to begin with (Basic Wheel Construction)
- Linchpins: to keep the wheels on (Axle Pin & Retention)
Typical Dimensions
| Part | Size |
|---|---|
| Bed length | 120-150 cm |
| Bed width | 80-100 cm |
| Shaft length overall | 250-300 cm |
| Ground clearance | at least 30-40 cm |
What One Animal Can Pull
The parent article’s practical maximums, for fit and well-fed animals:
| Terrain | Single horse cart | Ox cart (pair) |
|---|---|---|
| Good road or track | 400-500 kg | 600-800 kg |
| Rough track | 200-300 kg | 400-500 kg |
| Soft ground or mud | 100-150 kg | 200-300 kg |
| Steep grade over 10% | 150-200 kg | 300-400 kg |
These are practical limits, not theoretical ones. Overloading a horse on a rough track will break it down within days. For the animal side, see Draft Animal Training.
Building Order
- Cut and season the timber (Wood Seasoning).
- Build the frame and bed (Frame & Bed Construction).
- Make the axle and wheels, then fit them with linchpins.
- Fit the shafts and set the load balance (Shafts & Hitch Points, Tilt & Balance).
- Grease the axle (Lubrication & Wear) and test with half a load.
Common Mistakes
- Loading all the weight behind the axle — the shafts lift and the cart tips backward.
- Overloading the first trip — test at half load before committing.
- Forgetting spare linchpins — losing a wheel on a loaded cart in rough ground is a serious problem.
- Building for the best road — build the clearance for the worst track it will meet.
Safety
A loaded cart is a crushing hazard
A loaded cart can run away on a slope, drop its shafts when unhitched or tip back when the load shifts, and any of these can crush a person or kill the animal. Chock the wheels before unhitching, never stand downhill of a loaded cart, and do not ride a heavy load down a slope.
