Shovel capable of preventing motion thereof from being uniformly restricted

A shovel comprising:

• a traveling lower body;
• a revolving upper body rotatably installed on the traveling lower body;
• an attachment attached to the revolving upper body, the attachment including a driven object;
• an object detection device provided on the revolving upper body;
• a control device provided in the revolving upper body;
• a display device;
• and
• an actuator configured to move the driven object,
• wherein the object detection device is configured to detect an object in a detection space set in surroundings of the shovel, the detection space being part of a space monitored by the object detection device,
• wherein the display device is configured to display, regardless of whether the object detection device has detected an object, an image in the detection space obtained by the object detection device, or an image in the detection space obtained by an imaging device provided separately from the object detection device,
• wherein the detection space includes a first detection space with respect to the attachment, the first detection space being divided into a plurality of spaces, among which at least two spaces are spatially arranged one above another in a vertical direction,
• wherein the control device is configured to
• determine whether the object is detected based on an output of the object detection device,
• determine whether a motion of the driven object is toward the detected object in response to determining that the object is detected, and
• brake or inhibit the motion of the driven object in response to determining that the motion of the driven object is toward the detected object, and allow the motion of the driven object in response to determining that the motion of the driven object is not toward the detected object, and
• wherein a range of the detection space is set to be variable depending on a position of the attachment attached to the revolving upper body.
