Abstract: A display system includes: an image acquisition unit that acquires each of a first image of a work site imaged by a first camera and a second image of the work site imaged by a second camera; a viewpoint position calculation unit that calculates a viewpoint position of worker; a luminance adjustment unit that adjusts luminance of at least one of the first image and the second image based on the viewpoint position; and a display control unit that combines the first image and the second image having the luminance adjusted and causes a display device to display the combined image.

Abstract: A wheel traveling and operating vehicle includes a tire wheel traveling apparatus having axles in front and rear portions of a chassis frame body, an engine providing a traveling power, and a transmission. The transmission is provided with a transmission portion arranged so that an input shaft and an output shaft transverse an axis (X—X) in a vehicle longitudinal direction in parallel to each other at forward and backward positions of the axis and a bevel gear output portion outputting a tire wheel driving power to the output shaft toward a direction of the axis. The input shaft of the transmission portion is connected to the engine horizontally mounted to one side surface of right and left sides of the chassis frame body on the same axis as the engine output shaft and the bevel gear output portion is connected to front and rear tire wheel driving propeller shafts.

Abstract: A wheel type traveling and operating vehicle can reduce a height and a length in a longitudinal direction of a lower traveling body on which an engine is mounted, and can secure an improved operability and a traveling property. Accordingly, this vehicle is provided with a tire wheel traveling apparatus having axles (2, 3) in front and rear portions of a chassis frame body (1), an engine (11) providing a traveling power, and a transmission (12). The transmission is provided with a transmission portion arranged so that an input shaft (21) and an output shaft (23) transverse an axis (X-X) in a vehicle longitudinal direction in parallel to each other at forward and backward positions of the axis, and a bevel gear output portion (15) outputting a tire wheel driving power to the output shaft toward a direction of the axis.

Abstract: The present invention is a working vehicle having high visibility and transportability and is capable of providing a large excavation force over a wide range. To this end, a working unit (30) is provided with a boom (31), which is divided into a first boom (31a) and a second boom (31b), and an arm (32), which is fixed to a front end portion of the second boom (31b). The first boom (31a) is free to be swung by a first boom hydraulic cylinder (36) and the second boom (31b) is free to be swung by a second boom hydraulic cylinder (37). One end portion of a first arm link (33a) is attached to a front end portion of the second boom (31b), and one end portion of a second arm link (33b) is attached to a rear end portion of the arm (32), with one end portion of an arm hydraulic cylinder (38) and the other end portions of the first arm link (33a) and the second arm link (33b) being connected together.
