  • Publication number: 20240150161
    Abstract: 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.

  • Patent number: 11307080
    Abstract: The present invention relates to a method for determining the weight of a demountable platform. In the method, a hooklift is used to lift the demountable platform from the ground onto a vehicle, values of a force acting on a main cylinder of the hooklift are determined at predetermined intervals of a physical quantity that varies as a function of the movement of the hooklift, and the weight of the demountable platform is calculated using the determined values of the force. The present invention also relates to a system for determining the weight of a demountable platform.
