Abstract: A vehicle determination system (1) includes a loading platform detection unit (30) and a controller (50). The loading platform detection unit (30) detects information including a distance to a loading platform (13). The controller (50) calculates dimensional information about the loading platform (13) based on the distance detected by the loading platform detection unit (30). The controller (50) stores a correspondence between the dimensional information about the loading platform (13) and a type of a vehicle (10). The controller (50) determines the type of the vehicle (10) based on the calculated dimensional information and the stored correspondence.

Abstract: Provided is a crane including a guy link coupling part easily accommodatable at a predetermined position thereof. The guy link coupling part has a pair of left and right link members each extending in a front-rear direction, and a coupling member extending in a left-right direction and connecting the pair of link members to each other. A linking and retaining structure includes a first retainer provided on a boom for retaining the coupling member to restrict the coupling member from moving in the front-rear direction. The first retainer has: a first slope surface slanting inward of the boom, from a proximal position of the boom toward a distal end thereof; a second slope surface located closer to the distal end of the boom than the first slope surface and slanting outward of the boom; and a recess part disposed between the first slope surface and the second slope surface.

Abstract: A work system is a system for automatically operating a work machine including a work device. The work system includes a controller that controls an operation of the work machine so that a leveling work is performed, the leveling work including a leveling operation in which a work target object that has been loaded into a container by a loading work is leveled using the work device. The controller acquires information regarding at least one of the work target object in the container, the container, the work machine, and the loading work, and determines at least one of a start position of the leveling operation and an end position of the leveling operation by using the information.

Abstract: Provided is a system for accurately calculating the degree of clogging of a filter with reduced amount of required data. The system includes a controller. The controller stores a judgment permission condition including that the flow rate of hydraulic fluid passing through a filter exceeds a predetermined flow rate threshold, and calculates: a judgment-permissible time, which is an integrated value of time in which the judgment permission condition is satisfied; and a judgment target time, which is an integrated value of time in which the judgment permission condition is satisfied and the differential pressure across the filter exceeds a predetermined differential pressure threshold. The controller calculates the degree of clogging of the filter on the basis of a comparison between the judgment permission time and the judgment target time.

Abstract: Provided is a system and the like that can improve operability of a manipulation mechanism for an operator. Manipulation reaction forces f1(θ) and f2(φ) acting on manipulation levers 2111 and 2112 are controlled by controlling operation of actuators 214. At this time, the manipulation reaction forces f1(θ) and f2(φ) are controlled to cause reaction forces F1(θ) and F2(φ) in manipulation directions opposite to each other perceived by the operator through manipulation levers 2111 and 2112 (manipulation mechanism) to realize symmetry about a manipulation amount of zero, within a manipulation amount range in a positive manipulation direction and a manipulation amount range in a negative manipulation direction.

Abstract: A work machine includes: a reference posture setting part which sets a reference posture which is one of postures of a working device in a holding task; an estimative load determination part which determines, based on a load acquired by a load acquisition section, an estimative load of an object of a work estimated to be discharged at a position above a loading destination in a discharge task when a predetermined estimative load determinative criterion is satisfied; an output part which outputs an estimative result which is information about the estimative load determined by the estimative load determination part. The estimative load determinative criterion includes a criterion that a posture change amount representing a changed degree of the posture of the working device from the reference posture is equal to or larger than a predetermined change amount threshold for determination of the estimative load.

Abstract: A remote operation device and a remote operation system that can reduce or eliminate deviation of the position of an indicator image of a working unit such as a line image in an image with respect to the position of the working unit in a real space. In some case, because of a cause such as a communication failure, a position posture coordinate value of a working unit corresponding to captured image data in a work environment image deviates from a position posture coordinate value of the working unit estimated according to an operation form of a remote operation mechanism. In this case, a semitransparent indicator image Img2(τ2) simulating a bucket is superimposed on a work environment image Img1(τ2) in a position where the bucket is estimated to be originally present and deviating from an image region representing the bucket.

Abstract: There is provided a system and the like capable of assisting remote operation of a work machine performed by a remote operator in such a way that contact between the work machine and an actual machine operator and other unfavorable situations can be avoided. Even in a situation in which a first evaluation result is affirmative and a work machine 40 can be remotely operated via a remote operation apparatus 20, but in a situation in which a second evaluation result is affirmative and it is highly probable that a worker carrying a portable terminal 60, such as an actual machine operator OP2, is so close to the work machine 40 or on the work machine 40 that short-range wireless communication between the work machine 40 and the portable terminal 60 is established, remote operation of the work machine 40 is inhibited.
