Abstract: A shovel includes an attachment configured to execute work; a guidance unit configured to guide an operation of the attachment; and a display unit configured to display information related to the work by the attachment. The guidance unit changes color of a partial area or an entire area of a display screen of the display unit, depending on a distance between a position of the attachment while the work is being performed and a target surface as a reference of the work.

Abstract: A shovel includes a lower-part traveling body, an upper-part turning body, an attachment, and a controller. The upper-part turning body is turnably mounted on the lower-part traveling body. The attachment is mounted on the upper-part turning body, and has a consumable part attached to its leading edge. The controller is configured to obtain coordinates of the consumable part when the consumable part is caused to contact a predetermined feature, and to calculate the amount of wear of the consumable part based on at least two sets of the coordinates obtained under different conditions.

Abstract: A periphery-monitoring device for working machines creates an output distance image based on an input distance image taken by a distance image sensor attached to a working machine. The periphery-monitoring device for working machines includes a computer programmed to execute a process including obtaining coordinates on an input distance image plane on which the input distance image is positioned, obtaining coordinates on an output distance image plane on which the output distance image is positioned and associating the input distance image and the output distance image with each other.

Abstract: A shovel includes a lower-part traveling body 1, an upper-part swiveling body 3 installed in the lower-part traveling body so as to be rotatable relative to the lower-part traveling body, an attachment attached to the upper-part swiveling body, and a machine guidance device 50 of reporting a visual report or an audible report of a value of a difference between a present position of an end attachment and a target position of the end attachment, wherein the shovel includes a controller 30 that reports possible discontinuity of an accurate guidance in a case where it is determined that a predetermined event occurs. The controller determines that the predetermined event occurs in a case where it is determined that a change occurs in a position of the lower-part traveling body or a posture of the lower-part traveling body, and reports the possible discontinuity of the accurate guidance to the operator.

Abstract: A construction machine includes a lower-part traveling body that performs a traveling operation, an upper-part turning body turnably mounted on the lower-part traveling body, an operator's cab mounted on the upper-part turning body, multiple image capturing devices mounted on the upper-part turning body, and a display unit mounted in the operator's cab to simultaneously display an image and operating information regarding an operating condition. The image includes at least one of multiple images captured with the image capturing devices. The display unit is configured to change at least one of the displayed image and a display position of the operating information, in response to an operation of a single changeover switch.

Abstract: A construction machine includes an image capturing device configured to capture an image of the surroundings, an image display part mounted in an operator's cab and configured to display a menu screen showing an operating condition and various settings, or the captured image captured with the image capturing device, an operation part including a menu switch to cause the menu screen to be displayed on the image display part, and a detector configured to detect whether a work element is enabled or disabled. The image display part is configured to display a warning in response to the menu switch being operated while the work element is enabled.

Abstract: A shovel includes a lower traveling body; an upper turning body that is installed on the lower traveling body; an internal-combustion engine disposed in the upper turning body; an oil hydraulic pump that discharges hydraulic oil by power of the internal-combustion engine; a hydraulic actuator that is driven by the hydraulic oil discharged by the oil hydraulic pump; a fuel container that stores fuel of the internal-combustion engine; a first detector that detects a residual quantity state of the fuel; a reducing agent container that stores a reducing agent to be used in a selective catalytic reduction system; a second detector that detects a residual quantity state of the reducing agent; and an image display unit that is installed in a cabin, wherein the image display unit is configured to simultaneously image-display the residual quantity state of the fuel and the residual quantity state of the reducing agent.
