Abstract (en)
[origin: EP4086216A1] A crane (2) mounted on a vehicle (4), comprising a crane boom system, comprising crane components (6) that includes a crane tip (8); hydraulic actuators (10) which are arranged to apply movements to the crane boom system in response to received driving instructions (14); a sensor system (16); a control interface (20) arranged to receive a set of operating instructions, defining wanted movements of the crane components, and a crane controller (24) configured to generate driving instructions (14) to be applied by the hydraulic actuators. The crane controller (24) estimates a pressure level of a required working pressure of the hydraulic pump (12) and a required flow level of each of the hydraulic actuators for the wanted movements of the crane components (6), based on the generated sensor signals (18) and/or predetermined operation conditions, and estimates a waste contribution measure for the wanted movements of the crane components (6). If the estimated waste contribution measure is larger than a predetermined level, the crane controller (24) generates an energy consumption status signal (30) indicating that the present crane operations are inefficient.
