摘要： Provided is a swivel joint for which replacement costs can be kept low when worn. A swivel joint (A) for supplying and discharging various types of fluid between the top and bottom of a rotating platform comprises an outer cylinder (1), an intermediate cylinder (2), and an inner cylinder (3) that are fit concentrically around a central axis. The intermediate cylinder (2) can freely rotate with respect to the outer cylinder (1) and the inner cylinder (3), and a hydraulic fluid flow channel (4) is provided between the outer cylinder (1) and the intermediate cylinder (2). A hot water flow channel (5) between the lower portion of the inner cylinder (3) and the intermediate cylinder (2) comprises inner annular grooves (G) formed on the inner circumferential face of the intermediate cylinder (2). An air flow channel (6) between the upper portion of the inner cylinder (3) and the intermediate cylinder (2) comprises outer annular grooves formed on the outer surface of the inner cylinder (3). It is possible to suppress replacement costs because replacing the inner cylinder, which is the smallest part, suffices if the sliding surface opposite of the inner annular grooves (G) of the hot water flow channel (5) becomes worn.

摘要： Provided is an automatic boom extension/contraction device for a work machine in which it is possible to reduce the burden, such as arm or hand fatigue, on a worker inputting an operation for extending or contracting a boom when the worker actuates the boom so as to extend or contact. When, in a state in which an automatic extension/contraction switch (53) is ON, an engine rotation speed equal to or greater than a first predetermined rotation speed (R1) is detected by an engine rotation speed sensor (51) and an operation in which the speed of extension/contraction actuation of a boom (22) is equal to or greater than a predetermined speed is inputted through a boom extension/contraction lever (52), an automatic extension/contraction actuation is performed in which the extension/contraction actuation of the boom (22) is maintained in a state in which an operation of extending/contacting the boom (22) is not inputted through the boom extension/contraction lever (52).

摘要： A machine-position-information management system is disclosed, which is capable of reducing the transmission and data management costs in management of the work positions of machines. In the machine-position-information management system for a crane, a transmission controller determines whether the crane has started work, based on a result of the detection by a work-state detector, and when determining that the crane has started work, the transmission controller outputs the position information acquired from a GPS sensor at this time to a data management unit from a remote communication system. The data management unit is configured to save the position information when the crane starts the work and to output the saved position information upon request for use.

摘要： Provided is a work plan verification device capable of improving work efficiency of movement work of a suspension load. The work plan verification device determines whether an operator indicates a movement position of the suspension load on an image (A) displayed on a monitor (30). When a determination is made that the movement position is indicated, a mark is displayed on the movement position (B). Subsequently, a determination is made that the suspension load is suspended on a boom. When the determination is made that the suspension load is suspended, a load factor (C1) which is moving determination information allowing an operator to determine whether the suspension load can be moved to the movement position (B) is calculated, and the calculated load factor is displayed on the image (A).
