'Servotest' servo-hydraulic test machine

This machine has previously been taken in part-exchange and is now offered for sale. The sturdy, four-column loading frame has a movable crosshead with hydraulic clamping. Two motor-driven lead screws are used to power the crosshead up and down. A load cell is mounted on the hydraulic actuator rod.

Hydraulic actuator

• ± 250kN dynamic.
• 100mm stroke.
• Fitted with two Moog servo-valves. The manifold has provision for up to four servo-valves for high frequency work.)
