A suspension system for an agricultural or construction industry vehicle is described. The suspension system comprises two hydraulic cylinders, which support a frame in relation to an axle of the vehicle, the hydraulic cylinders each having a piston-side chamber and a piston rod-side chamber and each of the chambers of the hydraulic cylinders being connectable to one another via connecting lines provided with a switch valve, a first supply line, which can be connected via a switch valve to the piston-side connecting line of the first hydraulic cylinder, a second supply line, which can be connected via a switch valve to the piston-side connecting line of the second hydraulic cylinder, a hydraulic accumulator, in each case connectable to the supply lines via proportionally adjustable orifices, a hydraulic source, a hydraulic tank, a control valve device, and an electronic control unit. In order to prevent the activation of a suspension state in critical vehicle states, means for the detection and compensation of load states of the vehicle are provided in the suspension system.
