Abstract (en)
[origin: EP1593858A2] A hydraulic system (10) has a filter plant for the cleaning of the hydraulic oil (12) flow by filtration of particles, and a removing device for a defined part of a flow of the hydraulic oil. The removing device has filter element(s) for filtration of the partial flow of hydraulic oil. Independent claims are also included for the following: (A) a system comprising a reach stacker, and the above hydraulic system coupled to the reach stacker; and (B) filtering hydraulic oil in a hydraulic system of a reach stacker, comprising pressurizing hydraulic oil from the hydraulic system and providing the pressurized oil to an oil line; removing a defined flow portion of the pressurized hydraulic oil from the oil line; filtering the defined flow portion separately from remaining oil in the oil line via a filter; and supplying the filtered defined flow portion back to the hydraulic system at a lower pressure level.
