Abstract

PURPOSE:To raise the efficiency of ripping operation as well as automatically prevent the slip of crawler by a method in which when the slip rate of crawler during operation reaches more than a given value, the output of engine is controlled so as to obtain a preset mode by a control circuit. CONSTITUTION:A circuit 31 to calculate the speed of cawler 2 on the basis of signals from a sensor 24 for output rotation of torque converter and a sensor 25 for change gear steps is set. A circuit 32 to calculate vehicular speeds on signals from a sensor 27 for the back and further acceleration of vehicular body is also set, and a circuit 33 to calculate the slip rate of crawler on signals from these circuits is set. When the crawler slip rate detected by the circuit 33 reaches more than a given value, an electronic control type governor 10 is controlled by an engine output control circuit 34 to regulate the output of engine. The slip of crawler 2 can thus be automatically prevented.
