Abstract

PURPOSE: To attain the safety of passengers, by operating a relay and contacts attached to a brake valve and an emergency valve and holding the emergency valve and informing the operation of the emergency value until the stoppage.
CONSTITUTION: The contacts 8, 16 are attached to the brake valve 2 and the emergency valve 15 of power vehicle 1. When the brake valve is moved into emergency position or the emergency valve 15 is operated, during the running of the vehicle, a power source E is connected to the relay 18 through the contact 8 or the contact 16. Then, an emergency solenoid valve 19 is operated to start emergency braking. Simultaneously, a contact 18a3 is closed to turn on an emergency brake lamp 10 and an alarm 11 to inform the passengers of the emergency braking. Since the relay 18 is held by the power source E through a speed detector 17, the emergency braking is continued until the stoppage of the vehicle even if the brake valve 2 and the emergency valve 15 are returned to their original positions.
