摘要： In left and right web plates (12) of a boom (11), first to fifth web materials (12A to 12E) are joined at edge portions in a front-rear direction along welding lines (13A to 13D). In an upper flange plate (14), a rear upper flange material (14A), a front upper flange material (14B), and a middle upper flange material (14C) are joined at edge portions in a front-rear direction along welding lines (15A, 15B). Ina lower flange plate (16), first to sixth lower flange materials (16A to 16F) are joined at edge portions in a front-rear direction along welding lines (17A to 17E). The welding lines (13A to 13D) of the left and right web plates (12) are disposed in positions that are different from those of the welding lines (15A, 15B) of the upper flange plate (14) and the welding lines (17A to 17E) of the lower flange plate (16) in a front-rear direction. This makes it possible to reduce the entire weight and thereby achieve reduction in weight while ensuring bending strength, torsional strength, and the like of the boom (11).

摘要： An arm (11) of a hydraulic excavator (1) is formed as a box-shaped structural body surrounded by left and right side plates (12, 13), an upper plate (14), a lower plate (15), and a thick rear plate (16). An upper end (16A) of the thick rear plate (16) is protruded upward from an outer surface (14A3) of the upper plate (14). Upper ends (22B) of a pair of arm cylinder brackets (22) joined to an outer surface (16C) of the thick rear plate (16) are arranged higher than the outer surface (14A3) of the rear thick upper plate (14A) and lower than the upper end (16A) of the thick rear plate (16). As a result, in each of the arm cylinder brackets (22), a joint area with the thick rear plate (16) can be ensured large, and joint strength can be improved.

摘要： A hydro-static transmission travel system for a working machine enables the working machine to travel over a range from low speed to high speed with a simplified circuit arrangement. By referring to a machine traveling speed (vehicle speed) based on a detected signal from a rotation sensor, a controller computes respective target tilting amounts of hydraulic motors 10, 20 and controls the tilting amount for the hydraulic motors and a clutch. Depending on whether the traveling speed exceeds a setting speed as a reference boundary, the controller selectively switches over a drive mode between low-speed four-wheel drive, in which travel units 12, 22 are both driven, and high-speed two-wheel drive, in which the front-wheel side hydraulic motor 10 is controlled to zero displacement and only the rear-wheel side travel unit 22 is driven.

摘要： One of the mode lamps 38a, 38b and 38c of the mode indicator 38 corresponding to the current steering mode is turned on yellow and the other mode lamps are turned on green or turned off, thereby indicating whether front wheels 1, 1 and rear wheels 2, 2 are at neutral. A controller 39 does not operate a mode changing valve 24 even with an instruction outputted from a mode change switch 35 when the front and rear wheels are not at neutral, and operates, in response to an instruction outputted from the mode change switch 35, the mode changing valve 24 to establish a steering mode corresponding to the instruction when the front and rear wheels are at neutral. Also, the mode indicator 38 is controlled to always indicate, as the current steering mode, one corresponding to the steering mode actually established by the mode changing valve 24. With those features, in a working vehicle in which the mode of steering front and rear wheels can be changed over between two-wheel steering and four-wheel steering, a steering system having superior operability and high reliability can be provided.
