The hardware processor is further configured to control the shovel such that the distance is prevented from falling below a predetermined value.

Abstract: A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a cab installed on the upper turning body, a display device installed in the cab, and image capturing devices attached to the upper turning body. The display device is configured to simultaneously display a left mirror image and a right mirror image generated based on an image captured by at least one of the image capturing devices. The left mirror image is an image corresponding to a mirror image in a left mirror attached to the left front end of the shovel. The right mirror image is an image corresponding to a mirror image in a right mirror attached to the right front end of the shovel.

Abstract: A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a cab mounted on the upper turning body, an attachment attached to the upper turning body, and a display device provided in the cab. The display device is configured to display an image. The image includes numerical information items indicating the relationship between two positions of the leading edge of the attachment at two points of time and graphics each corresponding to one of the numerical information items.

Abstract: A shovel according to an embodiment of the present invention includes a lower traveling body, an upper turning body pivotally mounted on the lower traveling body, a hydraulic pump mounted on the upper turning body, a hydraulic actuator driven by hydraulic oil discharged from the hydraulic pump, an operating device used to operate the actuator, and a control device configured to control an acceleration/deceleration characteristic of the hydraulic actuator in response to an operation of the operating device depending on a work mode.

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.

Abstract: A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a cab mounted on the upper turning body, an operating apparatus installed in the cab, an actuator driven with the operating apparatus, and a processor configured to restrict the movement of the actuator. The processor is configured to determine the necessity of a restriction related to the movement of the actuator in accordance with whether the operating apparatus is operated with an operator's hand.

Abstract: An excavator includes a lower travelling body; an upper turning body mounted on the lower travelling body; a hydraulic pump installed in the upper turning body; a travelling hydraulic motor that is a variable displacement type motor configured to move the lower travelling body by being driven by hydraulic oil discharged by the hydraulic pump; and a control device configured to control a motor capacity of the travelling hydraulic motor so as to be switchable between a plurality of levels. The control device switches the motor capacity to a low rotation setting upon detecting that an operation for changing a travelling direction of the lower travelling body is performed.
