I think it is because hydraulic systems are stronger than pneumatic systems. if you know that is wrong then get an expert. : )
I think you'll find that actually, not all cranes are yellow. Other popular colours for cranes include red and white.However, construction vehicles such as rollers, bulldozers and cranes are often yellow as it is the most visible colour. This is important, as these machines can be very dangerous, and it is best that nearby people are aware of them.
That is not easy to answer simply ! -Somewhat like the early adventures in aviation, early earthmoving machines 'evolved' rather than being 'invented'. The main people in this were brothers, Charles and Benjamin Holt and a competitor C.L. Best. They both built 'caterpillar ' style tractors around the early 1900's. These early tractors were steam powered and usually for haulage and farming, but later found many uses. The advent of the kerosene engine (around 1910) and more efficient tracks made the first practical bulldozers around 1912. Caterpillar style tracks had been made by Englishman George Cayley around 1870, but were evolved and improved by Best and the Holts. Around 1920 the Holts opened up the Caterpillar Company and carried on making ever more efficient bulldozers and tractors ever since.
