Is it better and/or cheaper to use hydraulics and pneumatic systems over actuators?
The electrical actuators are a strong alternative to hydraulic and pneumatic solutions, because they are stable, powerful, small in size and easy to control. An actuator system is far cheaper in purchase and operation than an equivalent hydraulic system. Compared to hydraulic and pneumatic systems the total efficiency is much higher. This makes the actuator solutions worth considering in a time with increasing demands on environmental and energy issues.
