摘要： An excavator includes a lower travelling body, an upper rotating body mounted on the lower travelling body, an excavation attachment attached to the upper rotating body and including a boom, an arm, and a bucket, a control valve serving as a straight-travel valve, and a controller that is configured to control functioning of the control valve. The controller moves the control valve while at least two selected from the boom, the arm, and the bucket are moving simultaneously in a non-travelling state.

摘要： An excavator includes an excavation attachment including a boom, an arm, and a bucket, a left main pump and a right main pump mounted on an upper rotating body, a control valve serving as a confluence valve that merges an operating oil discharged from the left main pump and the operating oil discharged from the right main pump with each other, and a controller that can control functioning of the control valve. The controller moves the control valve to merge the operating oil discharged from the left main pump and the operating oil discharged from the right main pump with each other while the boom, the arm, and the bucket are moving simultaneously.

摘要： A shovel includes a lower traveling structure, an upper swing structure mounted on the lower traveling structure via a swing mechanism, an image capturing device attached to the upper swing structure to capture an image of an area surrounding the upper swing structure, and a display device. The display device is configured to display the image captured by the image capturing device such that distortion in a part of an edge of the upper surface of the upper swing structure is reduced compared with distortion in another part in the image.

摘要： A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a cab provided on the upper turning body, an orientation detector configured to detect the relative relationship between the orientation of the upper turning body and the orientation of the lower traveling body, and an alarm device configured to output an alarm when a backward travel operation is performed while it is detected by the orientation detector that the orientation of the upper turning body and the orientation of the lower traveling body are in a predetermined relationship. The backward travel operation is an operation to cause the lower traveling body to travel in the backward direction of the upper turning body.

摘要： 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.

摘要： 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.
