The controlling apparatus of bucket posture for constantly maintaining a posture of a bucket includes cylinder position sensors attached on the upper circumferences of cylinders for sensing operational positions of the cylinders, a car inclination sensor for sensing inclined angle of an excavator, an electronic adjusting unit for supplying a signal to a bucket adjusting angle installed inside an operating room, a controlling unit for receiving signals from the cylinder position sensors, a car inclination sensor and electronic adjusting unit to control an operational angle of respective cylinder, an amplifier for amplifying an output from the controlling unit, an electronic proportional valve driven by the amplified signal, an oil hydraulic pump for setting a constant oil pressure according to an output from the electronic proportional valve, and a multiple control valve for lengthening or shortening the position of respective cylinders according to operating oil from the oil hydraulic pump. Thus, content in the bucket is accurately moved, and working efficiency is improved to significantly reduce fatigue of an operator.
