The roadblock machine (anti-terrorism wall) product controls the open and closed traffic lane management equipment by controlling the movement of the movable shutter. It can be integrated with the electric gate system and parking system, or it can be used alone. Roadblocks are mainly used for the control of vehicles in special venues such as customs, military bases, government key departments, airports, prisons, nuclear power plants, port terminals, and logistics warehouses. The roadblock machine system has stable and reliable operation performance and is easy to integrate. anti-terrorism wall adopts a hoisting structure to greatly improve the ease of installation and maintenance. The roadblock machine adopts internationally leading low-pressure hydraulic drive technology, and the whole system is safe, reliable and stable. The wall can adapt to the harsh working environment, the working temperature range can reach -20 °C ~ 65 °C; the roadblock machine is sturdy and durable, the action is stable, the load is heavy, the noise is low; the main hydraulic components of the roadblock are widely used in sensitive areas. And motorway access and gates in key prevention areas, such as: highway toll stations, checkpoints, prisons, customs, government agencies, embassies, border inspections, logistics, port terminals, treasury, nuclear power plants, military bases, government key departments, airports Vehicles, banks, industrial and mining enterprises, parking lots and all special places that need to restrict the passage of vehicles, etc.; the on-duty personnel issue instructions through the control system, and the hydraulic barriers enable the roadblocks to rise and fall quickly. After the vehicles pass, the automatic detection by the inductance is detected. Roadblock device or The manual button operation makes the roadblock machine rise and fall quickly; in order to control the lane, the door is released or closed, and the purpose of forcibly punching the card is effectively prevented. Highly practical, reliable and safe.

[Working principle of roadblock machine]
★, roadblock machine mainframe: The main frame of anti-terrorism wall consists of rack, movable flap, hydraulic cylinder and two sets of balance mechanisms. The movable flap and the frame are connected by two sets of rotating shafts, and the upper and lower earrings of the hydraulic cylinder are respectively connected between the frame and the movable flap through the rotating shaft, which is a power source for the movement of the mainframe, and two sets of balance mechanisms are connected. Load balancing and buffering between the movable flap and the frame.
★, hydraulic system: The hydraulic system consists of the drive motor, hydraulic oil pump, combined solenoid valve, manual control valve, pressure indicator table, and another hydraulic system.
★, interface function description: Ascending and descending input: the command control input interface of the roadblock machine rises and falls; the limit time and the limit limit precise time can be adjusted: the limit time is avoided to prevent the roadblock machine from running in the blocked state for a long time and affect its life; Ascending solenoid valve and descending solenoid valve: switching and closing of the oil circuit solenoid valve of the hydraulic pump of the roadblock machine, thereby realizing the function of ascending and descending of the roadblock machine; raising and lowering the regulating valve to adjust the rising and falling speed.
