摘要： The present invention provides a construction machine adopting a structure that assures a predetermined sound pressure level along a forward direction relative to the construction machine and allows a warning horn to be miniaturized. Warning horns 12 and 13 are mounted in the vicinity of at least either a left headlamp 9 or a right headlamp 10 provided on the left side and the right side of a vehicle body 3 of the construction machine. The warning horns 12 and 13 are housed inside a bracket 11 used to mount the headlamp 9 or 10. The plurality of warning horns 12 and 13 are disposed on a single side toward the left headlamp 9 or the right headlamp 10. Since a front attachment 7 does not block the sound generated from the warning horns 12 and 13 and thus the warning sound can travel without hindrance along the forward direction, a predetermined sound pressure level is achieved with ease along the forward direction relative to the vehicle body 3.

摘要： A forward/reverse control system for a work machine cancels a second control state, in which forward/reverse switching control is performed by a second forward/reverse control means, by an operation of a first forward/reverse control means to return to a first control state in which forward/reverse switching control is performed by the first forward/reverse control means. The system is provided with a F-N-R lever unit 30 (the first forward/reverse control means) and F-N-R switch unit 40 (the second forward/reverse control means) that instruct forward, reverse or neutral, a controller 42 which performs forward/reverse switching control by giving priority to an instruction from the F-N-R lever unit 30 over an instruction from the F-N-R switch unit 40, and a selector switch 41 which by an operation of a switching control member 41a, instructs the controller 42 to switch to the second control state or to cancel the second control state. As a consequence, the system has made it possible to return to the first control state without an operation of the first forward/reverse control means.

摘要： A threaded joint for steel pipes that includes a pin and a box. The pin has an externally threaded portion, a nose, and a shoulder portion. The box has an internally threaded portion, a sealing surface, and a shoulder portion. The outer circumferential surface of the nose of the pin has an outward convex curved shape, and the sealing surface of the box has a tapered shape. Additionally, the cross-sectional area of the pin at a seal point is 35% or more of the cross-sectional area of an original pipe portion corresponding to an unprocessed portion of the pin, the seal point being a portion on the pin that first comes into contact with the sealing surface of the box when the pin and the box are joined.

摘要： A threaded joint for a pipe is disclosed in which scalability, compression resistance, and galling resistance are enhanced. The threaded joint includes a pin nose outer peripheral surface that forms an outward convex curve in an axial cross-sectional view; the convex curve is such that a composite R curve, in which a plurality of outward convex arcs having different radiuses of curvature are connected in sequence to a generating line of a cylindrical portion next to a male member, is curved such that the radiuses of curvature increase with distance from the male member and tangents on connection points of the arcs are aligned with those of corresponding arcs connected thereto; and the inner peripheral surface of a box component facing the pin nose is a tapered surface that interferes with the pin nose outer peripheral surface when connected to a pin component.

摘要： A first hydraulic circuit leads, as clutch control pressure, pressurized oil supplied from a first hydraulic pump, to a transmission control device after regulating the pressurized oil, and leads, as torque converter operation oil, pressured oil to a torque converter, and leads pressurized oil to an oil cooler. Through a second hydraulic circuit, pressurized oil from a second hydraulic pump is distributed to a circuit portion downstream of the pressure regulation valve and upstream of a safety valve and to a circuit portion downstream of the torque converter and upstream of the oil cooler. A flow control device changes a proportion of a rate of flow in the second hydraulic circuit so that a proportion of the rate of flow to the circuit portion downstream of the torque converter and upstream of the oil cooler increases as pressure at an entrance of the torque converter increases.
