Abstract
PURPOSE: To prevent a displacement of cargo space between the tractor and the trailer as well as collapsed cargo by a method wherein the emergency brake at the tractor is simultaneously operated in cooperation only when the emergency brake at the trailer is operated.
CONSTITUTION: After the tractor protection valve 9 is closed to cause the circuit pressure in the emergency lines 13, 15, 16, 32, the emergency valve 33 at the tractor and the emergency valve installed in the relay emergency valve 17 at the pole trailer are started to operate, the circuits 18, 30 at the trailer are communicated with each other, the pressurized air in the air tank 19 is flowed to the air chamber 31. Circuit 34 and circuits 39, 36 at the tractor are communicated with each other the pressurized air in the air tank 35 is fed or supplied to the air chambers 24, 25, respectively, and the emergency brakes are simultaneously applied to the pole trailer.
