At the time of brake braking of the job machine without manipulation of the engine halt prevention system

摘要

Disclosed herein is an engine stall prevention system for industrial vehicles. The engine stall prevention system includes a transmission, which is configured such that a hydraulic shuttle valve for performing forward and reverse switching without requiring the operation of a clutch pedal, and a control unit for controlling the shuttle valve. The control unit receives a brake pedal operation signal from a brake detection unit for detecting the operation of a brake pedal, detects the traveling state of a vehicle using a traveling detection unit, determines whether the speed and engine RPM of the vehicle are equal to or less than respective preset values, and performs automatic control such that the shuttle valve enters a neutral state or a half-clutch state if it is determined that the vehicle speed is greater than the corresponding preset value and the engine RPM is equal to or less than the corresponding preset value.
