Abstract:
A crane includes a control interface to receive an operating instruction defining a target position, and a controller to determine movements of crane components and to generate driving instructions to be applied to a system of hydraulic actuators. The controller estimates a pressure level of a required working pressure of a hydraulic pump of each of the hydraulic actuators for the determined movements, and compares the estimated pressure levels and identifies the hydraulic actuators as a high pressure function, or as a low pressure function, based on the comparisons. The controller determines a time period during a movement from a current position to a target position, in which only the hydraulic actuators identified as a high pressure function or as a low pressure function is/are activated, and generates driving instructions for the hydraulic actuators to perform the determined movements, including activation of the determined hydraulic actuators during the time period.
