Basic speed series
Barrier gate running speed from 0.6 seconds to 6 seconds. Speed faster than 1.5 seconds belongs to fast speed gate. From 2 seconds to 4 seconds speed is medium speed gate. Speed more than 4 seconds belong to slow speed gate.
Basic Arm brackets
There are mainly two kinds of arm brackets. One is specially for fast speed gate, another is mainly for medium speed and slow speed gate.
For the fast speed gate, arm bracket should be special design for emergency. When barrier arm falls fast, if car go ahead, arm will swing out. so swinged out bracket is a necessary.
For medium and slow speed gate, used for the longer arm of the barrier gate, arm bracket should fix the arm with screws, no swinged out design needed.
Installation direction
There are different direction of traffic, left or right, so gate installation direction has left or right different.
And it can be installed in left or right, and because of the two sides of the barrier housing are the same, arm comes from the middle of the gate.
