When was the shaduf first invented?
The shaduf, or sweep, is an early crane-like tool with a lever mechanism, used in irrigation since around 3000 BCE by the Mesopotamians, 2000 BCE by the ancient Egyptians, and later by the Minoans, Chinese (c 1600 BCE), and others.
What is a shaduf what was it used for?
shaduf, also spelled Shadoof, hand-operated device for lifting water, invented in ancient times and still used in India, Egypt, and some other countries to irrigate land. Typically it consists of a long, tapering, nearly horizontal pole mounted like a seesaw.
Who invented the shaduf?
The shaduf was widely spread in the ancient world, and several ancient civilizations dispute its origin. It was invented in the prehistoric times probably in Mesopotamia as early as the time of Sargon of Akkad (Emperor of the Sumerian city-states in the ca. 23rd and 22nd centuries BC).
How did the shaduf work?
A shaduf is a large pole balanced on a crossbeam, a rope and bucket on one end and a heavy counter weight at the other. By pulling the rope it lowered the bucket into the canal. The farmer then raised the bucket of water by pulling down on the weight. He then swung the pole around and emptied the bucket onto the field.
Why was shaduf invented?
The Egyptians built reservoirs made from bricks and mud to hold water. During floods, a connecting network of canals filled with water and the shaduf was used to refill the reservoirs. In Ancient Egypt, the River Nile flooded every June. The SHADUF project began in 2004 to study ancient irrigation techniques.
What is similar to a shaduf?
The pi cottah, used primarily in India, is similar to the shaduf but is operated by two people, one of whom acts as a moving counter weight to eliminate much of the strenuous work of returning the water container against a stationary counter weight.
How did the Egyptians use a Shadoof?
To lift the water from the canal, they used a Shaduf. A Shaduf is a large pole balanced on a crossbeam, a rope and bucket on one end and a heavy counterweight at the other. When the rope was pulled, it lowered the bucket into the canal.
How is the shaduf still used today?
A shaduf is a hand operated device used for lifting water out of a well or reservoir. It was invented by the Ancient Egyptians and is still used today, in Egypt, India and other countries. connecting network of canals filled with water and the shaduf was used to refill the reservoirs.
How is the shaduf used today?
Its still used today in some parts of the world. The egyptians built mud-brick reservoirs to trap and hold the water. These reservoirs lead out to a network of irrigation canals that filled with water during the flood and were refilled from the reservoirs using the shaduf.
Why is the shaduf so important?
The Shaduf was important to the ancient Egyptians because it helped water crops. Therefore they created the Shaduf to refil the irigation channels that they had built for the annual flooding. They used June as a time to rebuild their tools and fish.
Where is a shaduf still used today?
A shaduf is a hand operated device used for lifting water out of a well or reservoir. It was invented by the Ancient Egyptians and is still used today, in Egypt, India and other countries.
How does a shaduf make life easier?
In Ancient Egypt, the River Nile flooded every June. As well as moving the water with shadufs, the Egyptians went fishing and mended their tools during this time. The shaduf was used to lift water from one place to another to irrigate crops.

Here are some facts about the shaduf. A shaduf is a hand operated device used for lifting water out of a well or reservoir. It was invented by the Ancient Egyptians and is still used today, in Egypt, India and other countries.
What was the shadoof used for in ancient Egypt?

What do you need to know about a shaduf?
Typically it consists of a long, tapering, nearly horizontal pole mounted like a seesaw. A skin or bucket is hung on a rope from the long end, and a counterweight is hung on the short end. The operator pulls down on a rope attached to the long end to fill the bucket and allows the counterweight to raise the bucket.
How is the top beam of a shaduf used?
In both actions, the top beam serves mainly as a Class 1 Lever: pulling against the counterweight as the bucket is lowered and, as it is raised, the counterweight provides the Effort to lift the weight of water (plus a little extra effort provided by the operator pulling the bucket upwards). Build a model Shaduf and use it to lift a 1kg mass.
