Abstract

PURPOSE: To display the maximum work capacity easily by a method wherein the speed of a belt exhibiting the maximum work capacity is obtained, the upper and lower movement of a blade is controlled using the speed of the belt as a command and the speed of the belt is controlled at the desired value.
CONSTITUTION: The speed of a belt and the actual speed of a bulldozer 1 under various load conditions are each detected by means of a belt speed detector 2 and an actual car speed detector 4. Effective traction output is computed by means of an arithmetic circuit 5 on the basis of detected values, detected belt speed, detected actual car speed and computed effective traction output are successively memorized and held, and a curve of travelling performance is displayed to a curve annuciator 6. The speed of the belt obtaining the maximum effective traction output is acquired from the displaying contents of the annunciator 6, and the rise and fall of a blade 14 are controlled on the basis of deflection between signals indicating the speed of the belt and the output of the belt speed detector 2.
