TAKEUCHI MFG. CO., LTD.

A working vehicle includes a control valve unit, a first drive unit, a travel unit, a lower body, an upper body, a second drive unit, a cab, a plurality of work units and a plurality of traveling hydraulic motors, an operation unit, and a controller. The first drive unit includes a first hydraulic pump, a first electric motor. The controller performs a control of the first electric motor and the second electric motor to adjust a first rotation speed of the first electric motor and a second rotation speed of the second electric motor such that a total rotation speed of the first rotation speed and the second rotation speed matches a target rotation speed calculated from required amount of pressure oil.

A soil-and-sand intrusion preventing structure includes: a rear door; a bumper disposed to protrude more downward and rearward than the rear door when the rear door is closed; a soil-and-sand intrusion preventing wall member that extends longer than an opening range of an opening between rear end wall portions of body frames disposed on the left and right sides of a vehicle body, and is fixed to an upper surface of the bumper; and a flexible trim mounted on a trim mounting plate disposed inside and below a peripheral edge of a rear door frame constituting the rear door, the flexible trim having a planar shape that follows a planar shape of the soil-and-sand intrusion preventing wall member, wherein the trim is brought into contact with the soil-and-sand intrusion preventing wall member over an entire length thereof when the rear door is closed.

A working vehicle includes an upper body having a device compartment, and a hydraulically operating working device, the device compartment being provided with an electric motor as a drive source of the working device, a driven device driven by the electric motor, a motor bracket supporting the electric motor, and a vehicle body-side bracket supporting the motor bracket, the motor bracket being installed to the vehicle body-side bracket via an anti-vibration support having an anti-vibration function and providing support, at two parts of a lower part and one part of an upper part, with at least two sets of the electric motor on one side of a predetermined direction and the driven device on the other side arranged one above the other.

Maintenance of components to be maintained is facilitated in a working vehicle equipped with an electric motor as a driving source of a working unit. A working vehicle 1 includes an upper slewing body, a lower traveling body, working units that is operated by hydraulic pressure, an electric motor for driving the working units, a battery pack for supplying power for driving the electric motor: a battery pack compartment for installing the battery pack: and a battery cover that is openable and covers an opening in the battery pack compartment. In the battery pack, at least a battery management unit board, a cell management unit board, a charging fuse, and a service plug are disposed as the components to be maintained at positions within a reach of a maintenance worker's hand through the opening.

A working vehicle is provided that can easily perform a mounting and detaching operation of a battery therein. A working vehicle includes: a body frame; and a counterweight that is mounted on a vehicle rear portion of the body frame. The counterweight is mounted on the body frame by a plurality of fixing bolts that threadedly engage with the counterweight by way of the body frame from a lower surface side of the body frame.

An operation control system includes a control device having a hydraulic pump control unit that controls a hydraulic pump based on a level that an operator selects from levels in n stages (n being an integer of 2 or more). The hydraulic pump control unit has operation distance/current value corresponding data where an operation distance of an operating lever and a current value are made to correspond to each other in a corresponding manner with each level in the levels in n stages. A current value that corresponds to an operation distance of the operating lever at a present point of time is acquired from the operation distance/current value corresponding data that corresponds to the level that the operator selects, and controls the discharge amount of a pressurized oil that the hydraulic pump discharges based on the acquired current value.

Provided is a working vehicle in which an angle in a vertical direction of a display screen can be adjusted to an angle that allows an operator to easily watch the display screen. The working vehicle includes: a display device; a lateral pipe that allows a wire harness connected to the display device to pass through the lateral pipe, and is disposed in front of an operator seat, a fixing portion that includes a clamp mechanism that fixes the display device to the lateral pipe, and a waterproof grommet that engages with a wire harness inserting opening of the lateral pipe by fitting engagement. The display device can be rotated by using the lateral pipe as a rotary shaft by loosening fastening of the lateral pipe by the clamp mechanism. The display device can be fixed at a desired angle by the clamp mechanism.

A working vehicle is provided that can easily perform a mounting and detaching operation of a battery therein. A working vehicle includes: a body frame; and a counterweight that is mounted on a vehicle rear portion of the body frame. The counterweight is mounted on the body frame by a plurality of fixing bolts that threadedly engage with the counterweight by way of the body frame from a lower surface side of the body frame.

Provided is a working vehicle that includes a power source socket that can prevent the arrangement of a plug and a wiring that are connected to a power source socket at a place where an operator gets on or off the working vehicle and a place where a machine operation is performed. A working vehicle includes: a bracket disposed on a side of an operator seat; and a power source socket that is supported on the bracket. An insertion port of the power source socket Is disposed so as to be directed toward a rear side of the working vehicle.

An operation control system includes a control device having a hydraulic pump control unit that controls a hydraulic pump based on a level that an operator selects from levels in n stages (n being an integer of 2 or more). The hydraulic pump control unit has operation distance/current value corresponding data where an operation distance of an operating lever and a current value are made to correspond to each other in a corresponding manner with each level in the levels in n stages. A current value that corresponds to an operation distance of the operating lever at a present point of time is acquired from the operation distance/current value corresponding data that corresponds to the level that the operator selects, and controls the discharge amount of a pressurized oil that the hydraulic pump discharges based on the acquired current value.
