Abstract

A controller constituting a construction machine includes: a target value computing unit that generates a speed target value of a boom based on a lever manipulating signal; a target value correcting unit that corrects the speed target value; and a command signal output unit that outputs a command signal to a boom driving device based on the corrected speed target value. The target value correcting unit includes: a motion information acquiring unit that acquires motion information on a motion of an arm; a maximum value determining unit that determines based on the motion information a maximum correction value for reducing suppression of a floating motion by a floating motion suppressing unit as the motion of the arm becomes faster; and a correction value regulating unit that corrects the speed target value based on the maximum correction value.

First claim

The invention claimed is:

1. A construction machine comprising:
an undercarriage;
an upper revolving body;
a working equipment provided with a boom and an arm, the working equipment being provided on the upper revolving body;
a floating motion suppressing unit that suppresses a floating motion of the undercarriage corresponding to a motion of the boom; and
a controller that controls the working equipment, wherein
power to the working equipment is distributed and fed to a…
