摘要： A method and an apparatus for driving a hydraulic system of a construction machine, in particular a hydraulic excavator, having a plurality of control blocks which are fed via at least one pump each and each drive a plurality of hydraulically operated actuators of the construction machine. At least two control blocks are designed to drive the same actuator. The delivery capacity of the pump of the second control block can be connected up to the actuator via a delay element.

摘要： The present invention is directed towards a method for measuring the weight of bulk goods loaded or, alternatively, loading performance over time of hydraulic earth moving machines, excavators or similar machines which are provided with a hydraulically operated material loading scoop. Typically, these loading scoops rotate about and are supported on a loading arm. The scoop is controlled and tilted by a hydraulic piston-cylinder unit. The determination of the weight of bulk goods loaded or of the loading performance of the excavator is often required by the operator and the manufacturer of the apparatus, both for the determination of the performance of the apparatus per work shift, or for the computation of the fully loaded weight of a transport vehicle used in carrying away the bulk goods. The measured values used in determining the weight of the loaded material are the pressure in the piston-cylinder unit, arragned between the loading scoop and the loading arm, and an angle defined by the line passing between the pivot point ofthe shovel and the center of gravity of the empty shovel with respect to a horizontal line. These values are fed into a computer, and by using certain predetermined values and a simple force equation, the weight of the contents of the scoop is calculated and then visually indicated. The weight may be accumulated, and then indicated on command, in order to determine the total loaded quantity of bulk goods. Alternatively, the accumulated weight can indicate the loaded performance of the apparatus if displayed at predetermined time intervals.
