The new system has reduced the complexity further with fewer components, better packaging by the integration of several sub functions into one main manifold, less connecting points for simplified installation and reduction of potential leakage points.
The entire hydraulic system is fed by one large variable displacement pump. Although less complex, the new one pump system offers increased lifting flow and by using an “on-demand” maximum flow boost function only when lifting, the pump margin pressure setting has been possible to reduce, (now 20bar), what reduces energy losses, heat generation and emissions further while saving fuel.
