TeleGiga hydraulic retractable bollards are engineered for high-security vehicle entrances at military, industrial, governmental, and commercial facilities, as well as streets closed to vehicle traffic during specific hours. Powered by a hydraulic drive unit, these bollards feature manual hand pumps to operate in power failure scenarios. PLC-controlled electronics enable raising and lowering via various access methods such as card readers, biometric scanners (fingerprint or hand shape), radio controls, and key switches. Safety accessories like photocells, inductive loop detectors, flashing lights, and red/green signals can also be integrated seamlessly.
