SUMITOMO CONSTRUCTION MACHINERY CO., LTD.

A shovel includes a lower traveling body; an upper turning body turnably mounted on the lower traveling body; an imaging device attached to the upper turning body; a display device; and circuitry configured to display, on the display device, position information representing a relationship between positions of a person detected by the imaging device and the shovel and when the person whose position is represented in the position information is no longer detected by the imaging device, continue to display the position of the person who is no longer detected in the position information in a case where a predetermined condition is satisfied.

A work machine includes a lower travel body, an upper slewing body mounted on the lower travel body in a slewable manner, a work attachment including a boom attached to the upper slewing body in a raisable and lowerable manner, a hydraulic actuator attached to the work attachment, and a manual adjusting valve provided in piping extending from the upper slewing body to the hydraulic actuator. The manual adjusting valve is attached to the boom.

An excavator includes: a lower travel body; an upper slewing body mounted on the lower travel body in a slewable manner; an attachment attached to the upper slewing body; a control device configured to perform control related to activity of the excavator; a first input apparatus configured to receive an input from a user; and a display apparatus configured to display a screen operable in response to an input from the first input apparatus. The control device has a plurality of control modes for the control related to the activity of the excavator, and the display apparatus is configured to display one predetermined screen on which the user can discretionarily select one control mode from the plurality of control modes by performing an operation through use of the first input apparatus.

A work machine includes a lower traveling body; an upper turning body configured to turn with respect to the lower traveling body; an attachment attached to the upper turning body and including at least a boom or an arm; an operation device including one operation lever and another operation lever; and a control part, wherein the control part controls the attachment in a first control mode when the one operation lever is operated, and the control part controls the attachment in a second control mode when the other operation lever is operated.

An excavator includes a lower traveling body; an upper slewing body that is slewably mounted on the lower traveling body; a boom that is attached to the upper slewing body; an arm that is attached to an end of the boom; an end attachment that is attached to an end of the arm; a tilt sensor configured to detect a tilt of the excavator; and a control part configured to control a height of the end attachment during slewing of the upper 10 slewing body, in accordance with a detection result obtained by the tilt sensor.

A working machine includes a physical quantity detector, a circuitry configured to calibrate the physical quantity detector, and a transceiver configured to transmit a calibration result of the physical quantity detector to a management server that is located outside the working machine.

A road machine includes a tractor, a screed disposed behind the tractor and configured to level a first paving material, and a working device configured to supply the first paving material in front of the screed, wherein the road machine is configured to perform a process for paving an area having milling marks with the first paving material based on the milling marks on a second paving material, the second paving material having been used to pave a road surface, and the milling marks being shown in image information captured by an imaging device.

An excavator includes a lower traveling body; an upper turning body turnably mounted on the lower traveling body; and a control device including circuitry, the circuitry being configured to perform notification of whether or not the upper turning body directly faces a target construction surface based on information about the target construction surface and information about an orientation of the upper turning body.

A display device is provided. The display device displays an image captured by a first camera of a plurality of cameras, the captured image representing a situation around a shovel, and when a predetermined object is detected within an imaging range of a second camera that is different from the first camera, the display device displays an image representing that the predetermined object is detected outside a range of the displayed captured image of the first camera.

A shovel includes a processor, and a memory storing program instructions that cause the processor to obtain environmental information around the shovel, and perform determination related to an object around the shovel based on the obtained environmental information, by using a learned model on which machine learning has been performed. The learned model is updated to an additionally learned model on which additional learning has been performed based on teaching information generated from the obtained environmental information. In a case where the learned model is updated, the processor performs the determination based on the obtained environmental information, by using the updated learned model.
