Title:
WORKING DEVICE POSTURE CONTROL STRUCTURE OF WORKING VEHICLE
Document Type and Number:
Japanese Patent JP2624405
Kind Code:
B2
Abstract:
PURPOSE: In the working device posture control structure of a working vehicle composed so as to actuate the hydraulic cylinder of the working device on an operating signal sent from an operating lever for changing the posture of the working device, to automatically operate an engine so as to increase its output in the case of heavy load by composing the working vehicle so that the load acting on the working device may be detected through an existing structure.
CONSTITUTION: A working vehicle is provided with existing posture detecting sensors 20, 27, 28 which detect the posture of a working device 3 to a machine body and use the above detected values for controlling the posture of the working device 3. In the case where operating levers 9, 10 are operated from their neutral positions, a time lag in starting to change the posture of the working device 3 is detected by posture detecting sensors 20, 27, 28, and when the detected time lag becomes larger, an engine is operated so as to increase its output.
