Abstract

A shovel includes a traveling body, a turning body turnably mounted on the traveling body, an object detecting part configured to detect a predetermined object around the shovel, a controller configured to restrict a motion of the shovel or report detection of an object when the object is detected, and a canceling part configured to execute a cancellation of restricting the motion or reporting the detection. A person around the shovel is alerted at the time of the cancellation.

First claim

What is claimed is:

1 . A shovel comprising:
a traveling body; a turning body turnably mounted on the traveling body; an object detecting part configured to detect a predetermined object around the shovel; a controller configured to restrict a motion of the shovel or report detection of an object when the object is detected; and a canceling part configured to execute a cancellation of restricting the motion or reporting the detection, wherein a person around the shovel is alerted at a time of the cancellation.

2 . The shovel as claimed in claim 1 , wherein the canceling part is installed in a cab in such a manner as to be manually operable.

3 . The shovel as claimed in claim 1 , wherein the canceling part includes a switch exclusive for the cancellation or a switch normally used for a purpose other than the cancellation.

4 . The shovel as claimed in claim 1 , wherein the controller is configured to automatically execute the cancellation when an object that has been around the shovel is away from the shovel.

5 . The shovel as claimed in claim 1 , wherein
the person around the shovel is alerted simultaneously with the cancellation, or the cancellation is executed after the person around the shovel is alerted.

6 . The shovel as claimed in claim 1 , wherein the person around the shovel is alerted using at least one of light, sound, display, and vibration, when the cancellation is executed.

7 . The shovel as claimed in claim 1 , wherein the person around the shovel is alerted using a notifying part attached to the turning body or a cab, when the cancellation is executed.

8 . The shovel as claimed in claim 1 , wherein the person around the shovel is alerted using a notifying part around the shovel, when the cancellation is executed.

9 . The shovel as claimed in claim 1 , wherein the person around the shovel is alerted using a part configured to turn on or blink a display or a light visible to the person around the shovel, when the cancellation is executed.

10 . The shovel as claimed in claim 1 , wherein the person around the shovel is alerted using a sound generating part configured to generate a sound audible to the person around the shovel, when the cancellation is executed.

11 . The shovel as claimed in claim 1 , wherein the person around the shovel is alerted using a vibration perceptible to the person around the shovel, when the cancellation is executed.

12 . The shovel as claimed in claim 1 , wherein the person around the shovel is alerted using a portable device possessed by the person around the shovel or a loudspeaker, a display panel or a lighting apparatus installed in a work site.

13 . The shovel as claimed in claim 1 , wherein
the canceling part is connected to the controller, the controller is connected to a notifying part configured to alert the person around the shovel at the time of the cancellation, and the controller is configured to execute the cancellation and transmit a signal related to notification to the notifying part, in response to a signal from the canceling part.

14 . The shovel as claimed in claim 1 , wherein
the canceling part is connected to a notifying part configured to alert the person around the shovel at the time of the cancellation and to the controller, the controller is configured to execute the cancellation in response to a signal from the canceling part, and the notifying part is configured to alert the person around the shovel in response to a signal from the canceling part.

15 . A shovel comprising:
a traveling body; a turning body turnably mounted on the traveling body; a cab mounted on the turning body; a surroundings alarm attached to the turning body; an interior alarm installed in the cab; a switch installed in the cab to cancel alarming; and a controller including a person detecting function to detect a person around the shovel, wherein the controller is configured to start the alarming by the interior alarm in response to detecting the person around the shovel, and to activate the surroundings alarm and activate a lighting apparatus for at least a predetermined time simultaneously with cancellation of the alarming by the interior alarm, in response to an operation of the switch.

16 . The shovel as claimed in claim 15 , wherein the controller is configured to activate at least one of an audio output device that outputs an audio in conjunction with traveling, a horn, a work light, and a rotating light even when the shovel is not traveling, when canceling the alarming.

17 . The shovel as claimed in claim 15 , wherein the person around the shovel is alerted using a portable device possessed by the person around the shovel or a loudspeaker, a display panel or a lighting apparatus installed in a work site.

18 . The shovel as claimed in claim 15 , further comprising:
a camera attached to the turning body; and a display device installed in the cab, wherein the controller is configured to, in response to detecting the person around the shovel, display a camera image captured by the camera and an alarm image indicating a presence of the person around the shovel on the display device.
