Application
Testing rubber suspension components for trains. This frame is fitted with a special dual-area actuator capable of applying high mean loads as well as higher frequency dynamic cycles at lower load.
Frame
- 4 column frame. Moveable upper crosshead. Variable daylight space 0 to 1420mm
- Fail-safe crosshead clamping by high capacity disc springs with hydraulic cylinders to unclamp
- Servo-hydraulic actuator for axial (vertical) loading mounted on upper crosshead
- 500kN thrust compression for static and low frequency work
- 80kN thrust tension and compression for high frequency
- Stroke 300mm
- Integral displacement transducer
- Load cell mounted on end of actuator rod
- Side load support bearings on rod end with support brackets mounted to under side of crosshead
- Servo-hydraulic actuator for side (horizontal) loading application mounted to side of lower crosshead
- 50kN thrust tension and compression fatigue rated
- Stroke 300mm
- Integral displacement transducer
- Load cell mounted on end of actuator rod and connecting to side load part mounting table
- Side load part mounting table available
- Automatic compensation for dynamic oscillating masses in both axes – automatically corrects for the inertial load of adaptors and end fittings by using feedback from axially-mounted accelerometers.
