发明名称 Traveling system for heavy construction equipment
摘要 A traveling system for heavy construction equipment is disclosed, which can prevent a flow rate of a hydraulic fluid to be supplied to a traveling spool from being suddenly decreased when a traveling device and a working device are simultaneously operated, and thus can minimize operation shock due to sudden reduction in traveling speed. The traveling system includes a sensing device that detects manipulation of an operation lever of the working device or manipulation of a traveling pedal installed in the operation lever or the traveling pedal and outputs an electric signal to a controller in a specific operation mode. The traveling system also includes first and second variable displacement hydraulic pumps that are driven by an engine and have the same maximum capacity and a main control valve that controls the flow direction of a hydraulic fluid discharged from the hydraulic pumps.
