The competition of transmission technology

Although hydraulic technology is only a transfer of mechanical energy rather than the generation of mechanical energy technology. Just like the transport industry, it is only the transfer of goods rather than manufacturing goods. But just as transport will not go away, technology to deliver mechanical energy will always be needed.

Delivering mechanical energy, in addition to hydraulic, there are mechanical transmission (lever, gear, belt, chain, etc.), pneumatic transmission and electric transmission (motor, electromagnet). Hydraulic transmission ratio mechanical transmission is more flexible than pneumatic transmission. Hydraulic transmission is much more powerful than pneumatic and electric transmission, so it becomes the first choice in some applications. It is also like any other means of transport: planes, ships, trains, trucks. They are all for transport, but each has its own characteristics. Although there is competition in some applications, one cannot be completely eliminated.
