Abstract
PURPOSE:To effectively obtain the composite action of boom and slewing thereof by a method in which the horse power of engine is distributed so that the slewing action and boom action are ended at the same time according to the target angles of boom action and slewing action. CONSTITUTION:The target values of the rising action angle and slewing angle of boom which are selected by selection switches 19 and 20 are put in a controller C consisting of first - 7th arithmetic units 21-27. By controller C, a fixed engine horse power is distributed as a value such that slewing action and boom action are almost concurrently ended, whereby controlling both pumps 5 and 6 for boom and slewing.
