640 Hydraulic Barrier
The Model 640 is the ideal hydraulic barrier for controlling heavy traffic at wide entrances. The 640 operates continuously, raising aluminum beams from 13 to 23 feet long in as little as 4 to 7 seconds. The 640 always stops smoothly and gently thanks to an adjustable electronic braking system which slows the beam down before the end of its travel when opening and closing. A heat sensor monitors the operator temperature, switching on a cooling fan when required.
