SHOVEL AND METHOD FOR CONTROLLING SHOVEL
A shovel according to an embodiment of the present invention includes an engine (11) provided with a supercharger (11a), a main pump (14) connected to the engine (11), a hydraulic actuator (1A, 1B, 2A, 7, 8, 9) configured to be driven with hydraulic oil discharged by the main pump (14), and a controller (30) configured to control horsepower absorbed by the main pump (14). The controller (30) is configured to increase the supercharging pressure of the supercharger (11a) by increasing the horsepower absorbed by the main pump (14) before a hydraulic load on the hydraulic actuator (1A, 1B, 2A, 7, 8, 9) increases.
