Lifting column as some of the main places of maintenance equipment, more and more loved by everyone, then the lifting column anti-collision level standard is what.
The lifting column anti-collision level standard mainly refers to the blocking ability level.
Blocking ability level
The barrier blocking capability level code is represented by a combination of a collision energy code and an intrusion distance code. The blocking capacity of the roadblock shall be divided according to the results of the actual vehicle collision test. After the actual vehicle collision test, the vehicle shall lose the ability to continue driving, and the roadblock shall be able to maintain the blocking state.
It should be noted that the real vehicle collision results of A1/B1/C1 are very difficult to achieve, especially the real vehicle collision results of A1 and B1, which are almost only at the theoretical level for the lifting column. Because the vehicles in the real vehicle collision test generally use scrapped vehicles to reach the preset collision speed under the action of traction or gravitational acceleration, some mass parts on the vehicle will instantly break away from the car body during the collision, accelerating to fly away, such as the engine, gearbox, and the spacing of the lifting column is not enough to completely prevent these small volume and mass parts from passing through. Therefore, for the real vehicle collision results, a2/B2/C2 is already the actual best result.
In addition, due to the contingency of crash test and the difference of vehicles, and due to the high cost of crash test, it is impossible for manufacturers to carry out all four levels of crash test A, B, C and D for each product, so the crash results are generally comparable at the same level, but not completely suitable for cross-level comparison, for example:
1）C1>C2>C3，
2）A1>B1>D1>C1>E1
3) But C3 cannot be said to have stronger blocking ability than D2.
From the practical application point of view, B3 above can be considered as high safety level, C2 below can meet the basic urban applications.
