PURPOSE:To increase the degree of accuracy of work as well as automation by making correcting control during the play back operation and controlling a driving section while correcting a memory in a hydraulic construction machinery provided with a teaching/play back controller. CONSTITUTION:During the teaching/play back automation, control levers 1a and 1b are controlled correctively. After that, correcting signals are outputted to a controller 3 from transmitters 2a1, 2a2, 2b. Existing memory signals are corrected through a mode switching controller 3a by the correcting signals and are outputted to an electronic controlling controller 7 and, at the same time, storage of a memory 3b is renewed. In addition, an electronic system hydraulic valve 8 is controlled by the electronic controlling controller 7 to drive an acting cylinder 12. According to the constitution, the degree of accuracy of automation is increased with every play back control, and an operator's fatigue can be reduced. |
