Our company launched the third type of intelligent barriers in 2007.

These barriers possessed four technological innovations:
1) Clutch unit can be operated manually
2) Balance spring device
3) Silent operation
4) Intelligent detection

Seven national patents:
1) Decelerating unit
2) Limit location switch keep accurate
3) Clutch device
4) Machine core structure
5) Case with unique surface
6) Bar with unique surface
7) Excellent pucker structure

HL barriers are at the leading edge technologically. Ours were the first intelligent barriers with manually operable clutch units. In case of a power failure, just gently open the clutch unit to allow manual bar lifting. The microcomputer control is adopted for a smart limit unit, with limit switch together. When the bar rises to vertical it will automatically detect the signal and stop running.

Our barriers use a special process to effect internal movement. The unique mechanical construction with electronic high technology allows for free movement of the bar.

Security:
1) Intelligent obstacle return unit: In case of any obstacle during the bar falling process, the bar will reverse
2) Intelligent infrared photocell unit prevents collisions: If the infrared signal is interrupted, the bar will reverse if falling

Convenience:
1) The internal controller is easy to remove, dispose of and maintain. The system uses a full remote signal transmitting system, which is simple to install.
2) Easy to debug: Full automatic diagnostic function at power on (takes less than 1 second)

Extended functionality:
1) Loop detector connection: Convenient to connect to a loop detector
2) IC card system connection: Simple IC card system, simple parking lot charging system or toll road system
3)Press electronic wave keep from extruding protection.
