Abstract

A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, an attachment including a boom and an arm, a boom cylinder configured to drive the boom, an arm cylinder configured to drive the arm, a hydraulic pump configured to supply hydraulic oil to the boom cylinder and the arm cylinder, an input device configured to receive an input from a user, and a control device configured to control the hydraulic pump. The boom is attached to the upper turning body, and the arm is attached to a tip of the boom. When a predetermined work mode for performing hoisting work involving use of the attachment is selected in response to the input received by the input device, the control device sets a standby flow rate of the hydraulic pump to be greater than when the predetermined work mode is not selected.
