How to judge the quality of the elevator door?

Some customers often ask that the appearance and function of industrial lift doors are the same. As the saying goes, insiders will keep an eye on the doorstep. The editor will teach you how to distinguish the quality of the improvement gate through several configurations.

Balancing torsion spring and shaft part

Firstly, look at the torsion spring above the lifting door, which ensures the balanced operation of the door body. The following figure shows a comparison between Meigao and a certain manufacturer´s torsion springs, with different colors and sizes. The surface of Meigao´s torsion springs has undergone electroplating and corrosion resistance treatment, so they will not rust. The large torsion spring is mainly because the real material used for the door panel is relatively heavy, and the torsion spring that is too small cannot withstand the weight of the door panel. Some manufacturers, in order to save costs, can also equip smaller torsion springs by making the door panels lighter. But this reduces the overall structure and stability of the door, and the quality cannot be guaranteed.

2. The buffer is a safety protection installed at the end of the track to prevent the door from falling off the top due to motor failure. The important configuration of Meigao is standard. It can be seen that some manufacturers still save costs.

3. At the fixed end of the wire rope, Meigao also comes standard with a wire rope anti break device. When the torsion spring accidentally breaks, this protective device will quickly respond and forcefully fix the door to prevent damage caused by the door body falling. These basic standard safety devices still need to pay attention to whether the manufacturer has omitted them for you. Don´t look at this inconspicuous configuration, the overall safety will be different.

4. Let´s take a look at a small detail. Good quality starts from small details. The fixed hinge center hinge on the doors of Meigao is also thicker than the regular ones. It will be fixed more firmly. If a manufacturer wants to cut corners on these small parts, then it must be the same everywhere else.

The above comparison allows everyone to understand how to analyze the quality of products. Only manufacturers that combine good products with professional services are worth choosing. Instead of blindly choosing low prices, problems may arise later and after-sales communication may not be possible. Not only will it be an economic loss, but energy will also be wasted.
