How To Choose Automotive Car Lift

How To Choose Automotive Car Lift

First of all, see if the functional parameters can meet the requirements. The user should select the parameters of the lift according to the situation of his major model. Such as rated lifting quality, lifting height, passing width, using voltage and so on. Second, the main structure of the comparison. As previously mentioned, the double-column lift has sub-floor and gantry type points. The gantry type lift has good stability, high atmosphere, and convenient operation at the lower part, which is the main direction of current development. Bottom plate lifts are cheap and have many brands. They are the main selection equipment for small and medium-sized repair shops. Since the "internal-lift" double-column lift has obvious advantages over the traditional "lift-up" double-column lift, users should use the "internal lift type". Two-column lifts are available in twin and twin cylinders. The double-cylinder lifter works smoothly, and the user may prefer to use it; the price of the single-cylinder lifter is slightly lower than that of the twin-cylinder lifter. The drive of the lifting mechanism currently uses two types of chains and steel wire ropes. The chain transmission has good rigidity and smooth lifting; however, due to the certain elasticity of the steel wire rope, the lifting mechanism will have a crawling phenomenon when it is lifting, and the work stability is poor. Therefore, the user should use a chain-driven lift. Third, compare the major components. After the main structure is selected, the main components between the lifts of the same main structure should be compared next. The main components of the lift are: Post: Compare column size, plate thickness, height dimension. Gantry lifts should also pay attention to whether the column is an integral structure or a two-section connection. Lifting mechanism: Comparing the size of the cross section, the strength of the stiffness, the range and flexibility of the swing and telescope. Hydraulic station: The hydraulic station provides working power to the lift and is one of the most important parts of the lift. General lift manufacturers have chosen professional hydraulic manufacturers. It is often used in the form of motor gear pumps, imported and domestically produced. Imported from the United States, Germany, Italy and Japan and other brands, they generally have reliable quality, low noise, but the price is higher; domestic brands are uneven, users should pay attention to select the regular manufacturers of products. Hydraulic cylinder, chain, wire rope is the choice of regular manufacturers of products. Fourth, the comparison of security. Security can be divided into active security and passive security. Active safety refers to the safety and reliability of the lift's own work, such as whether the structure of the lift is reasonable and whether the strength and rigidity of each component is sufficient (such as the safety factor of the chain and wire rope specified in the standard cannot be lower than 5). Passive safety refers to the protection of the human body and equipment in the event that the lift loses active safety, such as whether there is a mechanical safety insurance mechanism (preventing abnormal drops), hydraulic self-locking protection, and mechanical limit protection (prevention) Machinery, vehicles, etc.), power outage protection and other devices. Fifth, the appearance quality is compared. Can compare the appearance design is beautiful, the work is fine, the quality of the weld, the surface treatment and so on. It should be noted here that the surface treatment of the lift is now sprayed and sprayed. The spray treatment method is far superior to spray paint treatment, and its durability and stability are very good. In addition to paying attention to the appearance quality, the paint-treated products should also pay attention to whether or not the surface of the underlying metal is pretreated with phosphating, etc. Sixth, compare service conditions.

 

  Good products also have good services. Comparing services can be compared from the following aspects: whether there is a complete manual and other factory data; whether to provide transportation, installation, training and other services; the size of the product warranty and the length of the warranty period; whether the manufacturer has a service organization or service network in the local area. And service response time. Seventh, compare the strength of the production plant. The above six points are to compare products from the technical aspect, but it is somewhat difficult for some users to compare such details. Another method of comparison is to compare the strength of the production plant. Generally speaking, formal large and medium-sized manufacturers (such as state-owned large-scale factories, military enterprises, and listed companies) have strong development capabilities, advanced technological methods, strict internal controls, and a comparative focus on their own brand image. Their product quality levels and identity are relatively high. Good; and a certain workshop manufacturer does not have its own development capabilities, rely on imitation production, limited process means, it is difficult to establish an internal control system, its product quality is difficult to guarantee, not to mention product identity, low cost and low price alone Participate in competition, can not afford responsibility for major quality problems. Eighth, understand other user word of mouth. Ninth, comprehensive and cost-effective. After comparing performance and quality, we have to consider the practical issue of price. However, it is also necessary to point out here that prices can be pursued without sacrificing safety (such as certain safety mechanisms that are not provided for in certain lifts; cutting corners, ignoring safety requirements, or failing safety certification from authoritative organizations). Etc.) For safety lifts that do not meet the requirements of safety lifts should be carried out one vote veto; nor to sacrifice performance to pursue prices (such as certain manufacturers of small lift tonnage, lifting height and width is difficult to achieve Use requirements, etc.) Must compare safety and performance indicators to meet the requirements of products with similar product quality and service levels, comprehensive comparison of performance and price, and selection of inexpensive products
