Do you dare to use such a lift?
Dare you use this lift? When you are hesitating for hundreds or even thousands of yuan, you often ignore this point. Don't choose products that are not guaranteed for the sake of being cheap!
Double column lift is the main equipment to lift goods for a kind of operation. There are many brands and types in the market, and the quality is also different. If we don't choose a high-quality double column lift, the lifted objects will be abnormal and damaged. So, what should we pay attention to when purchasing?
1 look at the track of double column lift
Since it is a lift, and it is a double column lift, so the lifting track must be intact, only in this way can we ensure that the lifted items have better safety effect. Of course, if there is deviation from the track, or if the track is blocked or not unobstructed, the lifted objects will certainly have problems or even be damaged. Therefore, the track intact is the key to high quality.
2. The degree of stability
If you choose this kind of double column lift is not stable, or they are very stable, then, for the lifted objects, they are very likely to fall or fall. In this way, not only the fault of this kind of lift, but also the whole object will be damaged and unusable, Especially when the car is lifted up.
3 Comparison of main components
After the main structure is selected, the main components of lifts with the same main structure should be compared. The main components of the lift are as follows:
Column: compare column section size, steel plate thickness and height size.
Lifting mechanism: compare the section size, stiffness strength, rotation and expansion range and flexibility, etc.
Hydraulic station: the hydraulic station provides working power for the lift, which is one of the most important parts of the lift.
General lift manufacturers choose professional hydraulic products. It is often used in the form of motor gear pump, there are imports and domestic points. The imported brands include the United States, Germany, Italy and Japan, which are generally reliable in quality, low in noise, but high in price; Domestic brands are uneven, users should pay attention to choose the products of regular manufacturers.
Whether hydraulic cylinder, chain and wire rope are products of regular manufacturers.
4 Comparison of safety
Security can be divided into active security and passive security. Active safety refers to the safety and reliability of the lift itself, such as whether the structure of the lift is reasonable and whether the strength and stiffness of each component are sufficient (for example, the safety factor of the chain and wire rope specified in the standard shall not be less than 5). Passive safety refers to the protection of the lift to the person and equipment in case of losing the active safety, such as whether there is a mechanical safety insurance mechanism (to prevent abnormal falling), hydraulic self-locking protection, mechanical limit protection (to prevent mechanical vehicles from rushing to the top), power failure protection, etc.
5 Comparison of appearance quality
It can be compared whether the appearance design is beautiful, whether the workmanship is fine, the quality of the weld, the surface treatment method, etc. Here we should pay attention to the surface treatment of the lift, now there are two kinds of spray painting and plastic spraying. Spray treatment is far better than spray treatment, its durability, stability is very good. For spray painted products, in addition to the appearance quality, we should also pay attention to whether the surface of the metal substrate is pretreated by phosphating.
6 Comparison of services
Therefore, in the market for the purchase of double column lift, we need to combine their trajectory, track, combined with their stability to choose the main components, safety, appearance quality, service, etc. only in this way, we can ensure the safety and quality of the goods brought by this double column lift.
