<p><P>PROBLEM TO BE SOLVED: To provide a hybrid construction machine which recovers hydraulic energy by converting the same into electric energy through power generation using the hydraulic energy exhausted from a hydraulic circuit when driving a revolving hydraulic motor. <P>SOLUTION: A hybrid construction machine comprises: a revolving hydraulic motor 21 which drives a revolving body 3; a hydraulic circuit 320 to supply the revolving hydraulic motor with hydraulic pressure; a revolving regeneration hydraulic motor 310 connected to the hydraulic circuit; pressure sensors 340A and 340B which detect hydraulic pressure inside the hydraulic circuit; and a revolving regeneration generator 300 which is driven by the revolving regeneration hydraulic motor. The hybrid construction machine supplies the revolving regeneration hydraulic motor 310 with the hydraulic pressure based on detection values of the pressure sensors 340A and 340B and stores electricity generated by driving the revolving regeneration generator 300 in a battery 120. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
