A working equipment including a base; a movable arm; a hydraulic system including a hydraulic cylinder provided with a cylinder cavity a piston, and a piston rod, the piston dividing the cylinder cavity in a first chamber and a second chamber; and a load holding valve unit. A pressure measurement member is arranged to measure pressure of the hydraulic fluid in the second chamber during an outward movement procedure of the piston rod. A working equipment control system is arranged configured to receive measured pressure values obtained in the second chamber during an outward movement procedure, and to evaluate the measured pressure values by applying at least one evaluation criterion related to risk of hydraulic cylinder buckling of the hydraulic cylinder. The working equipment control system is further configured to perform a predetermined activity to reduce the risk of hydraulic cylinder buckling in dependence of the result of the evaluation.
