  • Patent number: 9518375
    Abstract: A turning working vehicle is provided with a monitor arrangement structure where a driver's seat is arranged on an operation part disposed on a turning body, and a working part manipulation lever which manipulates a working part and a monitor which displays various information are disposed on either one of left and right sides of the driver's seat. The monitor is arranged in an upright state outside and in front of the working part manipulation lever, and a display screen of the monitor is directed toward a viewpoint side of an operator seated on the driver's seat and performing manipulation while viewing a front side. An outer manipulation lever is arranged in an upright state behind the monitor thus allowing the operator to view the display screen of the monitor between the outer manipulation lever and the working part manipulation lever within a field of vision of the operator.

  • Patent number: 7008169
    Abstract: A pair of supported portions are provided in a bifurcated manner on the base end of the boom of a work machine. Operation oil hoses for an arm cylinder and operation oil hoses for a bucket cylinder are guided and piped into the boom from between both the supported portions. A hose guide hole is provided below each of the boom support portions so that operation oil hoses for the boom cylinder are inserted into the respective hose guide holes. At an intermediate portion of the rear surface of the boom, the operation oil hoses are taken out from the inside of the boom through a hose attachment plate and connected to respective external hoses connected to the arm cylinder. At a tip end of the boom, the operation oil hoses are pulled out from the inside of the boom through a rear side inclined surface of an angle rib.
