30M2 Hydraulic System30M2 Hydraulic System
Low < 175 bar (< 2,500 psi) operating pressure, safer than high-pressure systems
Reliable 2-section gear pump
Main valve section dumped straight to tank when not used - less heat build-up
Large 300 litre (80 gal) oil tank
Avoids rapid oil recirculation
RH and LH return towers minimize flow distances and ensure through flow in tank
