The hydraulic lifter is constituted by an alloy structure which supports a single acting spring return CMI25N400X hydraulic cylinder powered by a pedal control MLP21HA air-hydraulic pump. The technical and dimensional details are shown in the drawing underneath. Jacks of different strokes and characteristics from the standard can be supplied on specific request.
They are used exclusively in lifting Vivalto train wagons with SIEMENS bogies for the regulation of the suspension by adding spacers between the side frame and the pneumatic suspension. This operation occurs by acting on the stud which projects from the pneumatic element through the hole in the side frame.
