Patent ID: 8820061

Claim:
A method for actuating a hydraulically movable working element, which is provided on a main body of a working equipment, comprising at least one main cylinder and at least one additional cylinder, which are pivotably mounted on the main body and engage with the working element, by which the working element is actuated so as to be movable up and down in a working range, the main and additional cylinders each comprising a connection on the piston chamber side and a connection on the piston rod side and being supplied via pressure lines of a hydraulic control device and, in order to carry out a pivoting movement of the working element, being supplied with a pressure medium pressurised from a tank by means of pumps and in each case the connections on the piston chamber side or the connections on the piston rod side of the at least one main cylinder and the at least one additional cylinder being operated as pressurised connections, wherein the pivoting movement in the rapid motion mode is actuated in a first working pressure range of the hydraulic control device, the pivoting motion in a working motion mode is actuated in a second working pressure range, which is higher than the first working pressure range, the pivoting movement in the heavy load motion mode is actuated in a third working pressure range, which is higher than the first and second working pressure ranges, the pivoting movement of the working element in the operating modes of rapid motion, working motion or heavy load motion is actuated in accordance with the prevailing working pressure, and in the first working pressure range, in which the pivoting movement is actuated in the rapid motion mode, the pressure medium is fed from a tank of the working equipment to each of the pressurised connections of the at least one main and additional cylinders, and in that the unpressurised connections of the respective main and additional cylinders are connected to the associated pressurised connection by a respective bypass circuit so that in each case the pressure medium discharged from the main and additional cylinders is carried off via the unpressurised connections and is fed to the respective pressurised connections of the same main and additional cylinders.
