Method and system for hydraulic control of concrete distribution boom

摘要

The present invention relates to a method and system for hydraulic control of a concrete distribution boom (14) having a plurality of boom arms (16).A plurality of hydraulic drive cylinders (18) for the boom arm (16) coupled to the joint are controlled by a hydraulic circuit (34), and a supply pressure is supplied to the hydraulic circuit (34) via a hydraulic pump (32) and the pressure signal is At least one pressure sensor (38) is grasped within the drive cylinder (18), respectively.According to the present invention, the maximum pressure in the drive cylinder (18) is determined from the pressure signal, and the supply pressure is adjusted by the electronic control unit (36) in accordance with the maximum pressure.
