Yale PMF Multiple-flow Hydraulic Power Packs
Multiple flow hydraulic pumps can advance 4 cylinders with the same speed at the same time by injecting equal amounts of hydraulic oil into each individual cylinder. This principle allows a synchronized lifting of machines or similar loads from a central point. Even under different loading conditions the cylinders advance in synchronisation.
Levelling of a lopsided load is easily possible by an individual control of each single cylinder. Tbe lifting phase is initiated by a push-button remote control box and can be interupted and continued at any time.
