  • Publication number: 20210189693
    Abstract: A hydraulic system includes: a regulator that adjusts a tilting angle of a pump; and a controller that controls the regulator such that a discharge flow rate of the pump is a lower one of an operation-requiring flow rate and a horsepower control flow rate. The controller stores a first horsepower control line and a second horsepower control line lower than the first control line. When an operating point exceeds the first horsepower control line, the controller decreases the tilting angle of the pump; when the operating point falls below the second horsepower control line, the controller increases the tilting angle of the pump. When the operating point exceeds the first control line or falls below the second control line, it is shifted and positioned between the first control line and the second horsepower control line, keeping the tilting angle of the pump as it is.
