A float is a form of two-wheeled horse-drawn cart, often with a dropped axle to give an especially low load-bed.
The high position of the axle ends allows large wheels, giving a smooth ride.
[5][6]: 20 Rather than a driving seat or box, they are driven from a standing position, alongside the load.
[5] The float design was also used for hauling heavy stone, horse ambulances, and carrying livestock.
In London, the Lord Mayor's Show was originally floated down the River Thames.
