I didn't think anyone made one this big - but they do. I'm not sure it will start your motor, but you could ask.

http://www.thomsonlinear.com/downlo...ulic_to_Electric_Actuator_Conversion_taen.pdfThe myth that hydraulic actuators are more reliable may also be due to the fact that many
engineers are familiar with a previous generation of electric linear actuators that often did
experience reliability problems. But electric linear actuators have benefited from dramatically
improved reliability of all electronic and electrical products. Consisting solely of a motor,
gearbox, lead or ball screw and often a clutch, electric linear actuators are also much simpler
than their hydraulic counterparts. Compare this to hydraulic systems that have many more
components such as a reservoir, pump, DC motor, motor relay, solenoid valve, check valve,
hydraulic cylinder, and push-button station. Based on highly reliable electronic technology and
with minimized possible points of failure, the reliability of electric linear actuators has improved
in recent years to the point that in the vast majority of applications they will outlive the
equipment they are installed on.
Nope. Nobody believes you didn't design it.Lol brownout, convince anyone of what? That I did the design, and that is the application?
Eliminating the pump, hoses, etc can make a linear actuator 25-30% more efficient than a comparable hydraulic system. .you are right linear actuators are much less efficient
To support my earlier remarks about weight, this 1200 Watt converter weighs only 15 lb. Actually, I'm glad you posted that because some of the applications listed on the page are some of the same ones I've been thinking about for such a component.I didn't think anyone made one this big - but they do. I'm not sure it will start your motor, but you could ask.

By adding a simple rotary type fluid divider device between the pump and the two cylinders a repeatable synchronization regardless of load not an issue.The problem with Impacs current EZ Lift systems is the mess they make, and the position control. I don't understand the mechanics, but they use a "natural" position control, using fluid. But still, during un-even loads the actuators see a 6" difference in position from shaft to shaft at full stroke!
