Archimedes
The block and tackle (or pulley system) was brought to us by Archimedes (287BC - 212BC) in Greece, but neither Archimedes, nor any who wrote about him and his extraordinary work dated the invention.stupid answer
2011 was the date of invention
A double pulley system is simple. Instead of one wheel like the single pulley system has, the double pulley system has two wheels and carries more heavier loads than the single pulley system can hold.
Double pulley systems are different from the one pulley system because the weight is now attacked to a pulley instead of an anchor. Another pulley is used to take some of the weight. A two pulley system only requires half the effort as a single pulley system.
yes they did they did i have a history degree. Sorry but the first pulley was not invented by the Egyptians it was invented by Archimedes of Syracuse in around 250 BCE.
