HYDRAULIC CIRCUIT FOR CONSTRUCTION EQUIPMENT
Provided is a hydraulic circuit of construction equipment, including a boom cylinder for controlling ascending and descending movement of a boom, which includes a valve unit having a first control valve configured to control a large chamber of the boom cylinder to selectively communicate with a small chamber of the boom cylinder, a second control valve configured to control the large chamber to selectively communicate with an oil tank, a third control valve configured to control the large chamber to selectively communicate with an accumulator, and a fourth control valve configured to control a part of hydraulic oil flowing to the accumulator to selectively flow to an assist motor.
