摘要:
A wheel loader (1) comprises steering cylinders (21 and 22), a steering pump (31a), a joystick lever (24), a pilot valve (42), an angular velocity corresponding value sensing unit (27), a notification component (29), and a controller (28). The pilot valve (42) controls the flow of fluid supplied from the steering pump (31a) to the steering cylinders (21 and 22) on the basis of how much the joystick lever (24) is operated. The angular velocity corresponding value sensing unit (27) senses a corresponding value that corresponds to the steering angular velocity that is changed on the basis of the fluid flow rate. The notification component (29) notifies the operator that the corresponding value has reached a threshold value preset on the basis of the upper limit of the steering angular velocity. When the controller (28) senses that the corresponding value has reached the threshold value, the controller (28) makes the notification component (29) give a notification.
