hydraulic jacking motor

Planetary gearboxes serve a major role in the mechanics of jacking system. Their purpose is to provide a mechanical advantage, i.e. to achieve a greater output force (to pinion) than the input force (from motor). This is accomplished by converting the high speed of a hydraulic motor and its relatively low torque into a low […]

In a rack-and-pinion system, motors drive the gearbox, which in turn drive the main jacking pinion. Motors produce modest torque, which is then multiplied by the gearbox and delivered to the pinion. Depending on the system, motors can be electric or hydraulic. Both have their advantages and drawbacks. Electric jacking motor, gearbox and brake Electric
