The axle passes beneath the load-bed of the cart but was cranked upwards at each side. This allows the load to be carried low, for stability and ease of loading with heavy objects such as churns or barrels. The high position of the stub axles allows large wheels, giving a smooth ride. The box body is open at the rear, with no more than a chain across for safety. Rather than a driving seat or box, they are driven from a standing position, alongside the load. Floats were drawn by a single horse or, especially in Ireland, a donkey.
