Abstract

PURPOSE: To enable locus of cutter end of bucket on shovel loader to be controlled as will in such a way that two operating cylinders are driven by respective variable discharge pumps, while one of said pumps is controlled by signals converted from control signal of or feed-back signal from the other of said pumps.
CONSTITUTION: Boom of shovel loader is driven by boom cylinder 5, while arm mounted on extreme end of the boom is swung by arm cylinder 6. In order to have bucket on the extreme end of the arm to be moved horizontally and/or in any other various directions, controller 12 of variable disharge pump 10 connected to cylinder 5 is controlled by signals from one of operating levers for boom cylinder 5 and arm cylinder 6. Whereas, controller 13 of other variable discharge pump 11 connected to cylinder 6 is controlled by signal from other one of said operating levers, or by converted signal of feed-back signal from controller 12 of variable discharge pump 10, said feed-back signal being converted in respense to locus of moving bucket 4 so that the bucket 4 can be moved as will by merely operating said operating levers for boom and arm cylinders 5 and 6.
