  • Publication number: 20210277624
    Abstract: A shovel includes: an arm rotatably attached to a boom rotatably attached to a revolving body; a bucket rotatably attached to the arm; a tilt mechanism configured to support the bucket that can be tilted to the arm; a bucket tilt angle sensor configured to detect a tilt angle of the bucket; and a tilt angle controller configured to control adjusting the tilt angle. The tilt angle controller adjusts the tilt angle by automatic control of the tilt mechanism so that a bucket line of the bucket becomes parallel to a target excavation surface. The automatic control of the tilt mechanism is enabled after moving the shovel and/or during rotating the shovel.

  • Patent number: 11047113
    Abstract: A surroundings monitoring system for a work machine includes a display device in a cabin of the work machine, an image capturing unit configured to capture an image of the surroundings of the work machine, and a processor configured to generate a surrounding image of the work machine and to cause a monitoring image to be displayed on the display device. The monitoring image includes a work machine image and the surrounding image placed along the periphery of the work machine image. The processor is configured to cause a magnified monitoring image to be displayed on the display device. The magnified monitoring image magnifies a partial area of the surrounding image in the monitoring image. The partial area is centered on a position closer to a predetermined target object included in the surrounding image than to the work machine image and includes the target object.
