Do You Know Who Really Invented the Wheelbarrow? Zhuge Liang
Wheelbarrow, It was invented by the Chinese minister Zhuge Liang, who lived during the Han Dynasty between 181-234. He used Liang's wheelbarrow to carry supplies to wounded soldiers. But because it was an important invention, it was used secretly without seeing the enemy.
The wheelbarrow was also used in Chinese agriculture, which is said to be thirty times more productive than the farming activities practiced in Europe at the time. Wheelbarrows, which are used to carry heavy loads, are used in many areas from the construction industry to gardening today.
According to the history book The Records of the Three Kingdoms, by the ancient historian Chen Shou, the single-wheeled cart today known as a wheelbarrow was invented by the prime minister of Shu Han, Zhuge Liang, in 231 A.D. Liang called his device a “wooden ox.” The handles of the cart faced forward (so that it was pulled), and it was used to carry men and material in battle.
The person driving the wheelbarrow, which contains a carriage placed on one or two wheels, steers the cart with the help of two handles on the back of the cart. In the travel notes of the Europeans who visited China in the 16th century, it was stated that the Chinese sometimes benefited from the wind force with the help of the sail they placed on the car.
The wheelbarrow began to be used in Europe from the 12th century. The first example of this can be found in France and in Chartres Cathedral, which dates back to 1220. In a draft text of 1286, the definition of the wheelbarrow was included. The most important difference of this wheelbarrow from the ones used in China is that the wheel is located in the front of the cart, not in the middle of cart.
British inventor James Dyson paved the way for easier handling of the car, thanks to a new plastic circular wheel structure he invented in 1974.
