Abstract: A load detecting device that can highly accurately detect the magnitude and direction of a load whose direction of action changes regardless of the dimension of a pin is provided. Also, a working machine that is provided with this load detecting device and allows work to be performed safely and highly efficiently is provided. The load detecting device is configured with a pin-type load cell 4 and a load calculating unit 30. The pin-type load cell 4 is provided with three pairs of or three strain detecting units that are placed in the circumferential direction of the pin body 1. The load calculating unit 30 selects, from among the three or more pairs of or three or more strain detecting units, two pairs of or two strain detecting units that are less influenced by a change in the cross-sectional shape of the pin body 1, and calculates a load that acts on the pin body 1 according to an output of these selected strain detecting units.

Abstract: The invention provides a basic information calculator 30 for calculating basic information for area limiting excavation control to control a work device 20 of a construction machinery so that the construction machinery does not perform excavation beyond a target excavation surface.

Abstract: Disclosed is a working machine that computes and displays moment by moment its dynamic stability and its state of contact with a ground in view of an inertia force and an external force applied to the working machine. Specifically, a working machine is provided with an undercarriage, a working machine main body mounted on the undercarriage, a front working mechanism attached pivotally in an up-and-down direction to the working machine main body, and a working attachment connected to a free end of the front working mechanism.

Abstract: To provide a work machine with high stability in which a dynamic balance can be evaluated easily while the influence of a sudden stop of an travel base, an upperstructure and a work front is taken into consideration. A stabilization control calculation unit (60a) and a command value generating unit (60i) are provided in a control device (60) of the work machine. The stabilization control calculation unit (60a) uses a sudden stop model and position information of each movable portion of the travel base and a machine body including the work front (6) to predict a change of stability until reaching a complete stop when a control lever (50) in an operating state is instantaneously brought back to a stop command position, and calculates a motion limit needed to prevent destabilization from occurring at any time instant until reaching the stop.

Abstract: A dual arm hydraulic excavator 200 has two front work devices A and B, provided on left and right sides of a front portion of an upper swing structure 3 and swingable in a top-bottom direction of excavator 200. Front work devices A and B have arms 12a, 12b, booms 10a, 10b and working devices 20a, 20b. An average of angle ?a of the arm 12a relative to the boom 10a and angle ?b of the arm 12b relative to the boom 10b is defined as an average arm angle ?c. A range of the average arm angle, in which the average arm angle ?c is larger than a predetermined threshold value ?c2, is defined as an unstable range N. A range of the average arm angle, from an inner side of the unstable range and adjacent to the unstable range, is defined as a stable state limit range M.
