The invention provides a pneumatic car arrester. A port A of a three-position five-way spring self-resetting hand valve is connected with a first air connection hole in a cylinder, a port B of the three-position five-way spring self-resetting hand valve is connected with a second air connection hole formed in the cylinder, and a port P of the three-position five-way spring self-resetting hand valve is connected with an air source. When a spring of the three-position five-way spring self-resetting hand valve is compressed, a piston rod extends outwards, and a blocking device is in a car blocking state; when the spring of the three-position five-way spring self-resetting hand valve is released, the piston rod retracts back, and the blocking device is in a car passing state; through the characteristic of the three-position five-way spring self-resetting hand valve, the effects that the blocking device is in the car blocking state when a user pulls a handle of the three-position five-way spring self-resetting hand valve and the blocking device is in the car passing state when the user releases the handle of the three-position five-way spring self-resetting hand valve are achieved, and therefore operation is simplified.
