What determines the anti-collision ability of the lifting column?

As a kind of security product with high anti-collision ability, lifting column has been applied in more and more important places and played an important role in ensuring the safety of entrances and exits. There are various styles of lifting columns on the market. How to see the anti-collision ability?

Zhuo Ao Shipeng believes that the birth of lifting column is due to safety requirements, so impact resistance and interception are his core functions. So which aspects determine the anti-collision ability of hydraulic lifting column? Here are three answers for you.

First, the interception height of the hydraulic lifting column

At present, the interception height of most lifting columns on the market is 600mm, so I won't talk about it.

Second, the cylinder diameter

The lifting column has large diameter and strong anti-collision ability.

Oil cylinder structure of hydraulic lifting column

Column structure is the most important factor affecting the impact resistance of lifting columns.

At present, the interception height of most lifting columns on the market is 600mm, and the diameter of columns is also 2 17mm, the biggest difference lies in the column structure. In column structure, the core is the intersection length between flange and column.

1, flange

Flange is the special name of lifting column assembly. It refers to a circular metal sheet around the column on the ground, which not only helps the column to rise and fall smoothly, but also relieves a certain lateral force when the column is hit. The lateral force when the lifting column is hit is a typical lever principle in physics. The more stable the fulcrum is, the greater the force it can bear.

Unlike many thin flange plates with the thickness of 10- 15mm in the market, most of the Zhuoao flange plates can reach 35mm or even 58mm, which not only makes the lateral stress fulcrum more stable, but also prevents the damage to the whole structure caused by vertical stress such as vehicle rolling.

Cross-sectional length of lifting column

2、? Cross length of cylinder

In fact, it is easy to understand, that is, when the column is in the rising state, the overlapping part of the column and the underground bucket. Don't underestimate the length of this intersection. From the lever principle, vehicle impact is the driving force, and column interception is the resistance. The longer the resistance arm, the greater the resistance that can be generated. Just like a tree, the deeper the root is, the less likely it is to fall down.

(Comparison of flange thickness and column crossing length with other manufacturers)

To sum up, the thicker the flange, the more durable the lifting column and the better the impact resistance; The longer the column cross length, the better the impact resistance. Every detail embodies painstaking efforts, and every detail represents the cost.
