Our company launched our first line of intelligent barriers in 2005. These barriers possess four technological innovations: 1) Silent operation 2) Clutch unit can be operated manually 3) Intelligent detection 4) Just one second for pole lifting Six national patents: 1) Decelerating unit 2) Intelligent detection 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 detect 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. Security: 1) Intelligent obstacle return unit: in case of any obstacle during the pole falling process, the pole will reverse 2) Intelligent infrared photocell unit prevents collisions: if the infrared signal is interrupted, the pole will reverse if falling 3) Two indicator lights can be connected (220V R&G): a) Red light indicates pole movement b) Green light indicates no pole movement 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 Technical data: 1) Pole length: ≤6m 2) Opening (Closing) time: 6s 3) Center height: 0.83m 4) Machine core working temperature: -40°C to +75°C 5) Electric working temperature:-20°C to +75°C 6) Rated voltage: 220V±10% 50Hz/60Hz, 110V±10% 50Hz/60Hz 7) Rated power: 80W 8) Relative humidity: ≤90% 9) Remote control distance: ≥30m
