Abstract: A working machine (1) includes a working device (4); a hydraulic system (5) including an actuator (50a, 50b, 50c), and a hydraulic pump (51) to supply a hydraulic fluid (S) to the actuator (50a, 50b, 50c); an electric device (6a, 6b, 6c); a power generator (7) to generate electric power to be directly or indirectly supplied to the electric device (6a, 6b, 6c); a first cooling system (10) to cool the electric device (6a, 6b, 6c) with a first cooling medium (A); and a second cooling system (11) to cool the power generator (7) with a second cooling medium (B). The first cooling system (10) includes a first heat exchanger (100a) to cool the hydraulic fluid (S) through heat exchange with the first cooling medium (A), a second heat exchanger (100b) to cool the second cooling medium (B) through heat exchange with the first cooling medium (A), and a third heat exchanger (100c) to cool the first cooling medium (A) through heat exchange with outside air to a temperature lower than temperatures before the heat exchange of the hydraulic fluid (S) and the second cooling medium (B).

Abstract: Provided is a work machine capable of appropriately controlling a loading work onto a carrier machine by verifying validity of a recognition result of the carrier machine. A hydraulic excavator includes an external measuring device that measures a surrounding environment, an information processing device that recognizes a dump truck present around the hydraulic excavator based on a measurement result of the external measuring device, a control device that controls an operation of the hydraulic excavator based on a recognition result of the information processing device, and a truck information acquisition device that acquires a position and vehicle class information of the dump truck through external communication. The information processing device corrects the recognition result of the dump truck based on the information acquired by the truck information acquisition device. The control device controls the operation of the hydraulic excavator based on the corrected recognition result of the dump truck.

Abstract: A controller of a wheeled hydraulic excavator executes control of a vibration suppression function to control the flow of a hydraulic fluid from a hydraulic cylinder that drives a work implement, thereby suppressing vibration of the hydraulic cylinder when the rotation speed of wheels reaches a predetermined speed or higher. Furthermore, the controller disables the control of the vibration suppression function when the vehicle body is jacked up by the work implement, even when a vibration suppression instructing device has given an instruction for enabling the control of the vibration suppression function.

Abstract: There is provided a work machine allowing a steering operation device to be enhanced in reliability. The steering operation device (42) includes a joystick (43), a first electric lever (60), and an input unit (110). The joystick (43) receives an operator's operation. The first electric lever (60) includes a first main body unit (61) and a first lever unit (62) tiltable with respect to the first main body unit (61), and outputs a tilt angle of the first lever unit (62) with respect to the first main body unit (61). The input unit (110) inputs an input to the first lever unit (62) of the first electric lever (60) to tilt the first lever unit (62) with respect to the first main body unit (61) of the first electric lever. The input unit (110) has an elongated hole (111) extending in the frontward/rearward direction. The first lever unit (62) is disposed in the elongated hole (111).
