Emergency engine RPM control apparatus for heavy construction equipment |
摘要 |
The present disclosure relates to an apparatus for contingency controlling an engine rotational speed of a heavy construction equipment, which is capable of contingency controlling the speed of an engine when a controller of the heavy construction equipment such as an excavator does not operate normally. The apparatus for contingency controlling an engine rotational speed including a machine control unit generating a driving signal to control an operation of the engine by transferring a control value received from a control dial to an engine control unit may include: an instrument panel electrically connected with the engine control unit and allowing an operator to select and control a desired engine rotational speed because a control algorithm for the engine rotational speed is made into a database; and a connection switch electrically connecting the instrument panel and the engine control unit when the control dial or the machine control unit does not operate normally.
