摘要： The invention relates to methods and systems for stabilisation of a vehicle with a chassis including a rear wheel bogie, a pendulum shaft rotatable through rotary bearings around an axis parallel to the longitudinal direction of the vehicle, a tipping arrangement on which a crane is arranged, and a stabilisation arrangement having first and second hydraulic stabilisation actuators in the rear wheel bogie. The tipping arrangement includes a rotating disk and rotary bearings, such that the rotating disk and crane are rotatable around a vertical axis, and first and second hydraulic tipping actuators in connection with the rotating disk, that can be rotated around a horizontal axis. The first stabilisation actuator and first tipping actuator are in fluid-mediated connection, and the second stabilisation actuator and second tipping actuator are in fluid-mediated connection. The stabilisation actuators are controlled based on the pressure at the tipping actuators.
