The reason hydraulic systems are used for large machinery and equipment is because you can route the hydraulic force using small pipes or tubes, not because it is efficient. You still need a motor to pump the hydraulic fluid.
Yes, hydraulics can exert a large force, but it takes a lot of energy to be created. Energy can neither be created nor destroyed, so what goes in must be greater than or equal to what comes out (since energy is lost in the process).
