Vehicle hired labor and loader

摘要

"Vehicle hired labor and wheel loader.The invention comprises a work vehicle, a boom attached to the vehicle, a tool attached to pivu00f3 the spear, an actuator for moving the tool in its controlavelmente pivu00f3,And a sensor of angular velocity to detect the angular speed of the tool.A controller is adapted to perform a function of self - restraint of the tool, automatically maintain an initial alignment of the tool.By processing the data of angular speed and controlling the movement of the actuator of the tool to maintain the angular velocity to zero.The controller is adapted to discontinue the self retention of the tool, when the operator manipulating an input device controlling the tool that affects the movement of the actuator.And resume the function of self retention of the tool in a new direction affected by the operator.The manipulation of the input device of self - restraint control allows the operator to enable and descapacite selectively the function of self - restraint of the tool.
