5D technology overcomes all disadvantages of 2D technology, such as mismeasurement.low precision.human factors , which are caused by following reasons:

   [1]Original errors caused by wheel rim deformation cannot be eliminated by compensation;

   [2]Errors caused by wheel clamp deformation can not be eliminated;

   [3]Precision of truck should be higher than that of cars, but 2D technology makes it lower; 

   [4]Different measurement results caused by different operational approaches and strength.

5D technology adopts anti-shake measurement technology. It can eliminate time errors caused by car body shake within 20 seconds, improving labor efficiency. Meanwhile, it avoids problems caused by wireless and high-frequency interference. It can be used at any indoor places.
