CONSTRUCTION MACHINE CONTROL MODE SWITCHING DEVICE AND CONSTRUCTION MACHINE

摘要

A construction machine control mode switching device includes: a plurality of actuators (2, 6, 7) performing different operations, drive means (10, 11, 12, 14, 15, 16) for driving the respective actuators, a plurality of operation levers (22a to 22c) for instructing the operations of the respective drive means, a plurality of limit switches (72a to 72e) for detecting that each of the operations levers has reached the vicinity of the operation area end, mode judgment means (controller 23) for judging whether the mode is a priority work mode according to the combination of the on/off states of the limit switches, and drive control means (controller 23) used when the mode judgment means has judged that the mode is the priority work mode, for controlling the drive means so that the output of at least one particular drive means becomes higher than usual or the output ratio becomes higher as compared to the other drive means.
