1, roadblocks machine system consists of: Buried roadblocks roadblock equipment mainly by the main frame, hydraulic station, electric control part of three parts: 1.1, the main frame: roadblocks mainly by flipping the body or body movements, base composition (anti- hit the nail tooth may need to install according to the customer). Whole steel structure, the use of 25 mm GB A3 mold steel, channel steel welded to international standards, with high-strength load-bearing capacity and anti-collision; body without appliances, line settings, waterproof, safe. The device is embedded in the driveway or designated location door, through the instruction duty vehicle traffic restrictions. 1.2 Hydraulic station: hydraulic transmission station consists of tanks, manual pumps, a full hydraulic solenoid valve, high-power motors, pumps, tanks, fuel gauge, oil standard, externally mounted level, a GB high-pressure hydraulic hoses and other components prepared wire It is the power source for the entire barrier system, the device is mounted roadblocks on one side, and supporting the use of roadblocks (which can rise and fall speed by adjusting the valve change), decentralization of power can be manually bezel can also be manually lifted. 1.3, the electronic control system: automatic electronic control components: control board, vice panel, GFCI, contact the high life without exposure to noise, precision start time setting (impact force in place after the anti-cylinder stroke increases the service life of the cylinder) can be set to automatically rise (plus sense coil over the bar from the car). Automatic Controls: Includes control box, remote control, manual buttons control the use by the duty officer.
