Abstract: A work machine capable of continuing work by automatic operation over a large area includes a controller that makes an upper turning body and a work device perform a series of motions including processing motion a plurality of times. The controller performs: shifting the start position of the processing motion in the next series of motions in the turning direction of the upper turning body when a processing work performed by a series of motions reaches a predetermined stage; making a lower traveling body perform an area change movement when the processing work reaches a predetermined stage while the start position has reached a change limit plane; and setting an after-movement start position so as to make the processing work after the area change movement continued with the processing work before the area change movement.

Abstract: A work machine system includes a lower travelling body, an upper slewing body slewably attached to an upper portion of the lower travelling body, an attachment having a bucket that is capable of holding a work object and is rotatably attached to the upper slewing body, and a controller. The controller controls the upper slewing body and the attachment so that the upper slewing body and the attachment perform a series of operations having a plurality of operation phases, detects an amount of the work object held by the bucket, sets a target amount that is a target of the amount of the work object, and specifies, as an abnormal phase, an operation phase in which the amount of the work object held by the bucket is smaller than the target amount.

Abstract: Provided is a work machine capable of loading a transport object at a fixed point of a loading target. A controller is included that automatically performs an operation of discharging soil and sand held by a bucket (33) by driving a boom (31), an arm (32), and the bucket (33) based on a target loading point (P) set above a loading bed (56). After the controller rotates the bucket (33) such that the opening surface of the bucket (33) becomes vertical at the target loading point (P), the controller drives the boom (31), the arm (32), and the bucket (33) such that the opening surface of the bucket (33) faces downward while maintaining the position (T), with respect to the machine body, of the leading end of the bucket (33) in a front-and-rear direction.

Abstract: A controller (30) of an excavation system controls a bucket (15c) to excavate an excavation object (O) along an excavation row (C). In a case where the bucket (15c) is located forward (X1) of a border (53) at completion of one excavation performed by the bucket (15c), the controller (30) causes the bucket (15c) to perform next excavation without changing the excavation row (C). In a case where the bucket (15c) is located on the border (53) or rearward (X2) of the border (53) at the completion of one excavation performed by the bucket (15c), the controller (30) changes the excavation rows (C) and causes the bucket (15c) to perform the next excavation.

Abstract: A technology that further facilitates automatic driving control of working machines includes a working area setting system that includes an area setting unit. The area setting unit is provided to set a working area. The working area is a predetermined range in which an operation target of a working machine is stacked.

Abstract: A memory stores, in advance, target line information indicating an arrangement target of an object to be conveyed and related to a target line denoted by at least one of a curve or a polyline. A controller is configured to: calculate, based on the target line information, target information which is at least one of information about a target coordinate of the object and information about a target direction of the object; calculate, based on the at least one of the coordinate of the object and the direction of the object detected by the detector, detection information which is comparable with the target information; calculate a deviation of the detection information from the target information; and cause a display to display a moving direction of the object which allows the deviation to decrease.

Abstract: Provided is an automatic leveling system restraining leveling-objects from collapsing. The automatic leveling system includes a work machine that performs leveling motion, an imaging device, and a controller. The imaging device acquires three-dimensional information about the shape and position of at least one of the leveling-objects and a peripheral object. The work machine is provided with a work attachment including a tip attachment. The controller sets a leveling area based on the acquired three-dimensional information and makes the work machine perform the leveling motion by the tip attachment within the leveling area.

Abstract: To allow a worker to visually recognize information for assisting transportation of a transport object and the transport object at the same time. A guidance system includes a guidance device and a controller. The guidance device has a display portion. The controller stores information of a target position of a transport object. The controller calculates a detected position which is a current position of the transport object based on a detection result of a detection portion, and further calculates a position deviation which is a deviation of the detected position from a target position. The display portion displays information of the position deviation.

Abstract: Provided is a holding apparatus capable of holding a holding object with sufficient holding force from either of the outside and the inside. The holding apparatus includes a holding-apparatus body, a first and second arms, an opening and closing mechanism, a driving device, and a first and second holding elements. The opening and closing mechanism interconnects each of the first and second arms and the holding apparatus main bodies so as to allow the first and second arms to be moved in the opening and closing direction while kept in the holding posture. The first and second holding elements is pivotably connected to the arm lower region, having respective inner contact surfaces opposed to each other in the opening and closing direction and respective outer contact surfaces facing the opposite side.

Abstract: Provided is a construction machine capable of restricting halt of a function controlled by a controller when a key switch is in a key-off state. The construction machine includes an interruption switch switched between a supply allowing state of allowing supply of power from a battery to the controller and a supply interruption state of interrupting the power supply; a sensor detecting presence/absence of interruption necessary motion necessary for manipulating the interruption switch; and an alarm control device that causes an alarm device to issue an alarm only when the following conditions are all satisfied. The key switch is in the key-off state; the interruption switch is in the supply allowing state; the controller is being operated; and the sensor has detected presence of the interruption necessary motion.
