摘要： The invention essentially regards a hydraulic fluid arrangement for a hydraulic circuit of a vehicle, especially an industrial vehicle. This arrangement has a hydraulic fluid primary tank (2) located in a first place of the vehicle capable of storing a hydraulic fluid. The hydraulic fluid arrangement, further, comprises a satellite secondary assembly (3) hydraulically connected to the main hydraulic tank (2). The satellite secondary assembly is located in a second place of the vehicle and includes at least one or more function means coming from the group of: hydraulic fluid falling means; hydraulic fluid level controlling means; inlet connection means; and hydraulic fluid filtering means. In effect, the invention offers a hydraulic fluid arrangement which is separated into (i) a main hydraulic tank whose only function is to store a hydraulic fluid and, as such, can be of any shape and can be located in any suitable place in the vehicle, and (ii) a satellite secondary assembly which concentrates all the functions where an access is needed and as such has to be placed in the vehicle in a place offering an easy access.

摘要： An excavator includes a frame, and a platform on top of the frame. A hydraulic distribution system is received on top of the frame but below the platform. A pilot valve unit is at least partly received on top of the platform. The platform includes a dedicated hole capable of receiving therethrough at least that part of the pilot valve unit which is received on top of the platform. The pilot valve unit is fixed, directly or indirectly, on the platform. The pilot valve unit can be mounted from below the platform, through the dedicated hole, and is fixed on the platform from above the platform.
