EMERGENCY STOP SYSTEM FOR A HYBRID EXCAVATOR

WIPO Patent Application WO/2012/011618

A1

Disclosed is an emergency stop system for a hybrid excavator, including an emergency switch and an emergency stop part. The emergency stop system applies power from a power source to a hybrid controller and to an engine controller during normal operation. When the emergency switch is pushed, the applied power is cut off. Accordingly, when the equipment fails to work and an emergency occurs, the hybrid system can be effectively stopped. Also, when the emergency switch is pushed, power is applied to an emergency alarm part and an energy discharge part to provide notice of the malfunction of the equipment and of the occurrence of the emergency to the operator and to the people around the operator, and to simultaneously expend the hybrid power.
