Abstract

A shovel includes a traveling body, a turning body turnably mounted on the traveling body, an attachment attached to the turning body and including a boom, an arm, and a bucket, and a hardware processor. The hardware processor is configured to output a warning about the operation of at least one of the traveling body, the turning body, and the attachment when the shovel is on sloping ground or is likely to enter sloping ground. The hardware processor is configured to output the warning when the traveling body is traveling on the sloping ground in a downward direction or is likely to travel on the sloping ground in the downward direction. The warning alerts an operator to the tipping of the shovel in the downward direction of the sloping ground.

First claim

What is claimed is:

1. A shovel comprising:
a traveling body including a pair of right and left crawlers;
a turning body turnably mounted on the traveling body;
an attachment attached to the turning body and including a boom, an arm, and a bucket; and
a hardware processor configured to output a warning through a display device or an audio output device or a combination thereof when the shovel is on sloping ground,
wherein the hardware processor is configured to determine whether or not the traveling body is traveling on the sloping ground in a downward direction or is likely to travel on the sloping ground in the downward direction, and output the warning to alert an operator to tipping of the shovel in the downward direction of the sloping ground in response to determining that the traveling body is traveling or is likely to travel on the sloping ground in the downward direction.

2. A shovel comprising:
a traveling body including a pair of right and left crawlers;
a turning body turnably mounted on the traveling body;
an attachment attached to the turning body and including a boom, an arm, and a bucket; and
a hardware processor configured to output a warning through a display device or an audio output device or a combination thereof when the shovel is on sloping ground,
wherein the hardware processor is configured to
determine whether an orientation of the attachment matches a traveling direction of the traveling body traveling on the sloping ground in a downward direction and whether a height of the bucket from the sloping ground is more than a predetermined threshold,
determine that the shovel is in an unstable attitude state that increases a chance of a tipping of the shovel in the downward direction of the sloping ground in response to determining that the orientation of the attachment does not match the traveling direction of the traveling body and the height of the bucket is more than the predetermined threshold, and
output the warning, restrict a movement of the traveling body, the turning body or the attachment or a combination of one or more thereof, or output the warning and restrict the movement, in response to determining that the shovel is in the unstable attitude state.

3. The shovel as claimed in claim 2 , wherein the hardware processor is configured to restrict the movement in response to determining that the shovel is in the unstable attitude state when the traveling body is still on the sloping ground after a predetermined time or more passes since the hardware processor outputs the warning.

4. A shovel comprising:
a traveling body including a pair of right and left crawlers;
a turning body turnably mounted on the traveling body;
an attachment attached to the turning body and including a boom, an arm, and a bucket; and
a hardware processor configured to determine whether the shovel is on sloping ground,
wherein the hardware processor is further configured to output a warning and teach the operator a stable attitude that prevents tipping of the shovel in a downward direction of the sloping ground through a display device or an audio output device or a combination thereof in response to determining that the shovel is on the sloping ground.

5. The shovel as claimed in claim 4 , wherein the hardware processor is configured to determine whether the shovel is in an unstable attitude state that increases a chance of the tipping of the shovel in the downward direction of the sloping ground, and teach the operator the stable attitude in response to determining that the shovel is on the sloping ground and in the unstable attitude state.

6. The shovel as claimed in claim 4 , wherein the hardware processor is configured to teach the stable attitude by encouraging the operator to so operate the attachment as to bring the bucket closer to a ground.

7. The shovel as claimed in claim 4 , wherein the hardware processor is configured to teach the stable attitude by encouraging the operator to so operate the turning body as to reduce a difference between an orientation of the attachment and a travel direction of the traveling body.

8. The shovel as claimed in claim 4 , wherein the stable attitude corresponds to a posture state of the attachment where a height of the bucket from the sloping ground is less than or equal to a threshold.

9. The shovel as claimed in claim 1 , wherein the hardware processor is further configured to output, together with the warning, a notification to encourage closure of a window of a cabin or a notification to encourage wearing of a seat belt to the operator through the display device or the audio output device or the combination thereof, when the shovel is on the sloping ground.

10. The shovel as claimed in claim 9 , wherein the hardware processor is further configured to restrict a movement of the traveling body, the turning body or the attachment or a combination of one or more thereof when the window is not closed or the seat belt is not worn, when the shovel is on the sloping ground.
