Articulated working machine vehicle

A working machine vehicle provided with a supporting frame and a pivoted load container,

• wherein the vehicle is configured to allow tilting of the load container from a transport position to a tilted position for dumping of a load from the load container,
• wherein the vehicle is provided with a suspension arrangement configured to reduce transfer of vibrations between the frame and the load container when the load container is in its transport position,
• wherein the suspension arrangement comprises a spring element and a damper element,
• wherein the vehicle further is provided with at least one hydraulic hoist cylinder connected between the frame and the load container and arranged to lift and tilt the load container to the tilting position for dumping,
• wherein the hydraulic hoist cylinder forms part of a hydraulic system comprising a container for hydraulic fluid and at least one conduit that connects the hydraulic hoist cylinder with the container so as to form a flow passage for hydraulic fluid between the hydraulic hoist cylinder and the hydraulic container, and
• wherein the flow passage is arranged to exert a flow resistance to a hydraulic fluid flowing through the flow passage so as to dampen an oscillating flow through the flow passage and thereby form the damper element of the suspension arrangement.
