A joystick for operating utility vehicles is provided. The joystick has a handle area, and the handle area has a substance-to-substance connection to a support element. At least three conductor elements are arranged on the support element. At least one conductor element is designed as a heating element, one conductor element is designed as a temperature sensor element, and one conductor element is designed as a touch-sensing element.

A hydraulic system for a working machine includes hydraulic actuators actuated with hydraulic fluid delivered from a hydraulic pump, control valves each of which is shiftable among shift positions to control a flowrate of hydraulic fluid flowing to the corresponding hydraulic actuator, a detection fluid passage, an interlocking control valve, and a pressure detection unit. Each control valve includes an input port, an output port, and a flowrate reduction section. One of the control valves includes a flowrate increase section. The interlocking control valve is configured to be shifted in accordance with a shift of the one of the control valves among the shift positions and to be shifted to a blocking position to block a pilot fluid introduced into the interlocking control valve from the detection fluid passage when the one of the control valves is shifted to the increase position.

Provided is a work vehicle capable of preventing spillage of load materials from a bucket, even without adjusting an angle of the bucket in a scene where a traveling state is switched from a flat ground traveling to an inclined ground traveling. In a wheel loader 1 comprising a bucket 21 provided on the front of a vehicle body to scoop and discharge a work object, an inclination sensor 33 for detecting an inclination angle θ of the vehicle body is provided, and the controller 6 is configured to, in the case where a height position of the bucket 21 is higher than a predetermined height and it is determined that the vehicle body is in a state of being inclined rearward, activate a bucket cylinder 22 to a side for causing the bucket 21 to dump and correct an angle of the bucket 21.

Provided is a work vehicle capable of satisfying a user's demand to brake performance in a flexible manner. A wheel loader 1 comprises a controller 5 storing a plurality of control characteristics each of which is set such that a brake valve control pressure Pi of a solenoid proportional valve 45 increases as a pedal angle θ of a brake pedal 43 increases, and under the condition where a pedal angle θ is equal to or less than a predetermined pedal angle θ, an increase rate of the brake valve control pressure Pi with respect to the pedal angle θ varies. In a case where the pedal angle θ detected by a potentiometer 33 is equal to or less than the predetermined pedal angle θth, the controller 5, calculates the brake valve control pressure Pi based on the selected one control characteristic.

A working machine includes: an operating body switchable between a first position to prevent an operator from getting on/off an operator's seat and a second position to allow the same; a plurality of hydraulic actuators whose operation is enabled when the operating body is in the first position and disabled when in the second position; a manipulation member to be manipulated to operate the hydraulic actuators; and a pattern switching member to be operated switchingly to select one from among a plurality of manipulation patterns of the manipulation member to operate the hydraulic actuators. When the operating body is in the first position, at least a part of the pattern switching member is covered by the operating body so that the pattern switching member is impossible or difficult to be operated. When the operating body is in the second position, the pattern switching member is exposed to be operable.

An apparatus for drilling with a drilling machine including a boom for supporting a drill and a feed for feeding the drill. A single joystick is adapted for controlling the movement of the boom and the feed independently or together, such as according to different protocols (e.g., for causing movement of the boom and feed in the same direction, or in different directions). Related methods are also disclosed.

An apparatus for facilitating bucket movement of a material handling machine includes a joystick biased to a neutral position, movable away from the neutral position in a first direction along an axis to a first position, and movable away from the neutral position in a second direction along the axis, opposite the first direction, to a second position. The apparatus further includes an operator input movable from a disengaged position to an engaged position in which a bucket of the material handling machine is configured to automatically move in an oscillatory motion. When the operator input is in the engaged position, an intensity of the oscillation is dependent upon a position of the joystick along the axis, decreasing along the axis from the first position to the second position.

A work vehicle specification change system includes an information input to receive a specification change request in a free text format to change a specification of an in-vehicle device of a work vehicle, the specification change request being sent from an operation device on which an input operation is performed by a user driving the work vehicle, a specification update information generator to generate specification update information, based on the specification change request in a free text format, and an information output to transmit the specification update information to the work vehicle.

A work vehicle includes: a vehicle body that travels; a boom attached to the vehicle body to be vertically swingable; a work tool mounted to a front portion of the boom; a first illumination lamp that is disposed in the vehicle body and emits an illumination light forward; a second illumination lamp that is disposed in the boom and emits an illumination light toward the work tool; and an illumination controller that controls the first illumination lamp and the second illumination lamp, the illumination controller executing a lighting restriction of automatically turning off or dimming the first illumination lamp while the second illumination lamp is turned on.

A shovel includes a hydraulic actuator, an operating apparatus used to operate the hydraulic actuator, an obtaining device configured to obtain information concerning the vibration of the body of a shovel, and a hardware processor. The hardware processor is configured to perform such control as to reduce the responsiveness of the hydraulic actuator to the operation of the operating apparatus when the body of the shovel is vibrating or the vibration is likely to occur in the body of the shovel, based on the output of the obtaining device.
