Manual tire breaker/manual obstruction roadblock

  • No:Cheng Hui
  • Quantity:

    First, Product characteristics:

    This product is based on the expansion frame made of aluminium alloy (the base of the new manual aluminium alloy tyre breaker is ground). The product can expand freely and the length of expansion can be reached.8 meters. The utility model can be opened at will when in use, and can be simply closed after completion of work. There are 158 zinc-aluminium alloy triangle needles on the telescopic frame. The needle face is equipped with an exhaust groove. The length of the exhaust groove is 15 mm, and the interior is a hollow structure.

    Two. Working principle:

    When the wheel rolls over the top of the triangle pin, the wheel pressure will cause the triangle pin to be pulled out instantaneously and stably penetrated into the tire. The faster the wheel speed is, the deeper the triangle pin is inserted into the tire, and the faster the air leakage speed is. Generally, four or six steel pins will be penetrated into the tire.In 20 seconds, all the gas will be released to effectively intercept the vehicle.

    Three. Usage method:

    1. Open the box, take out the blocking roadblock and put it on one side of the road. The policeman holds the nylon rope attached to the blocking roadblock on the other side of the road. When suspicious vehicles appear, pull the rope to block the roadblock. (Police officers can stand in safe positions and use blocking roadblocks)

    2. After that, pull the nylon rope backward or kick the aluminium bar to make it integrated automatically. At the same time, police officers should replace the lost or damaged triangular steel needle in time for reuse. Then, the roadblock is loaded into the box, the rope is wound back to the winding ditch and the lid of the box is covered.

    Notes:
    1. The roadblock after use should be checked, the position of each triangle needle should be corrected, the damaged triangle needle should be replaced, and the missing triangle needle should be repaired to ensure the effectiveness of the next use.
    2. To protect the triangle needle from damage, attention should be paid to avoid stabbing operators in maintenance and use.
    3. If the roadblocks are contaminated with dirt, they need to be cleaned with water and dehumidified in time. After drying, the triangle needle should be corrected and put into the box.
    Fifth, installation method of triangle needle:
    1. Pull out the damaged triangle needle;
    2. Remove the spare triangle needle.
    3. Align the flat end of the triangle needle to the fixing sleeve and insert the fixing sleeve hole. (Must wear gloves to avoid injuring hands)
    4. Check and calibrate the position of the triangle needle.
