Six national patents:
1) Decelerating unit
2) Intelligent ***ection unit
3) Clutch
4) Machine core structure
5) Box with unique surface
6) Pole with unique surface
Wejoin 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 pole lifting. The microcomputer
control is adopted for a smart limit unit, requiring no limit switch. When the
pole rises to vertical it will automatically ***ect the signal and stop running.
Our barriers utilize a special process to effect internal movement. The unique
mechanical construction with electronic high technology allows for free movement
of the pole.
