Shovel

Abstract

A shovel includes a lower traveling body; an upper turning body that is turnably mounted on the lower traveling body; an attachment that is attached to the upper turning body; a posture detection device configured to detect a posture of the attachment; and processing circuitry configured to determine, based on position information of a slope and a posture of the attachment, whether or not the attachment and the slope contact each other during turning of the upper turning body.

What is claimed is: 
     
         1 . A shovel, comprising:
 a lower traveling body;   an upper turning body that is turnably mounted on the lower traveling body;   an attachment that is attached to the upper turning body;   a posture detection device configured to detect a posture of the attachment; and   processing circuitry configured to determine, based on position information of a slope and a posture of the attachment, whether or not the attachment and the slope contact each other during turning of the upper turning body.   
     
     
         2 . The shovel according to  claim 1 , wherein
 upon determining that the attachment and the slope contact each other during the turning of the upper turning body, the processing circuitry is configured to control a turning actuator such that the attachment and the slope do not contact each other during the turning of the upper turning body, the turning actuator being configured to turn the upper turning body.   
     
     
         3 . The shovel according to  claim 1 , wherein
 the processing circuitry is configured to determine whether or not the attachment and the slope contact each other during the turning of the upper turning body while a predetermined operation tool is being operated.   
     
     
         4 . The shovel according to  claim 1 , wherein
 during the turning of the upper turning body, the processing circuitry is configured to move a predetermined portion of a bucket along the slope in response to an operation by an operator on an operation device configured to operate the attachment, the bucket being included in the attachment.   
     
     
         5 . The shovel according to  claim 4 , wherein
 upon the upper turning body facing the slope, the processing circuitry is configured to stop a turning actuator configured to turn the upper turning body.   
     
     
         6 . The shovel according to  claim 5 , wherein
 upon the upper turning body facing the slope, the processing circuitry is configured to stop an attachment actuator configured to move the attachment.   
     
     
         7 . The shovel according to  claim 2 , wherein
 the processing circuitry is configured to inform an operator that the turning actuator is controlled such that the attachment and the slope do not contact each other during the turning of the upper turning body.   
     
     
         8 . A shovel, comprising:
 a lower traveling body;   an upper turning body that is turnably mounted on the lower traveling body;   an attachment that is attached to the upper turning body;   a posture detection device configured to detect a posture of the attachment; and   processing circuitry configured to calculate a track drawn by a predetermined portion of the attachment upon turning of the upper turning body, or an approximate straight line of the track.
