​Development Prospect of Hydraulic Jack

Development Prospect of Hydraulic Jack
 There are many kinds of jacks. Today, several kinds of automobile jacks are introduced. Change the tire with a jack.                    

 1.  screw jack            

 Advantages: light weight, easy to carry, simple care, safe and reliable use            

 Disadvantage: low transmission efficiency, slow return               

 2.  Hydraulic jack            

 Advantages: Easy to use, time-saving and labor-saving            

 Disadvantage: Component and volume are larger, relatively not easy to carry.           

 Jack is a common product of small lifting equipment. Its application boundary is quite ordinary. It is not only the necessary equipment of various motor vehicles, but also has ordinary use in construction, railway, automobile maintenance and other parts.            

The market for jacks is quite large. At present, the annual output of automobiles in the world is more than 60 million. In 2010, the number of automobiles in China alone reached 70 million. Therefore, the Chinese jack Market for automobile matching and maintenance is over 50 million. With the accelerating pace of modernization and the enlargement of city scale, people will rely more on large-scale transportation equipment such as automobiles, yachts and so on, and the demand for jacks in the market will also increase.            

The jack industry belongs to the work-intensive industry. Compared with the developing countries, the cost of work force in developed countries is much higher. The advantage of low cost of work force in our country makes our country one of the key exports of all kinds of Jack products, which also brings excellent opportunities to our Jack industry. At present, China still has a number of enterprises devoted to the development and manufacture of various Jack products, most of which are scattered in Jiangsu and Zhejiang provinces.           

 However, with the renewal of the concept of consumers, the demand for jacks is no longer satisfied with a single performance, but gradually reveals the trend of natural and diversified demand. The difference in demand for Jack performance among  people with different matching scenery reflects that in the current oversupply market, consumers are still slowly taking the lead in the market.            

 There are several ways to prolong the service life of hydraulic jacks.            

 (1)  Before using the hydraulic jack, make sure that the bottom is flat and firm, and there is no oil plate to expand the pressure surface. In order to prevent sliding and ensure safety, boards should not be replaced by iron boards.            

 (2)  The hoisting must be smooth. Before that, check the weight for any special conditions. Only in the absence of special circumstances can we continue to improve. The driver can not lengthen or over operate the handle arbitrarily.            

 (3)  Hydraulic jacks should not be overloaded or over height. If the casing reaches the rated height, a red line will appear, and the jacking should be stopped at this time.            

 (4) If several hydraulic jacks work at the same time, synchronous lifting is very important. In particular, the adjacent two hydraulic jacks should keep the wood blocks, in order to prevent sliding, the two hydraulic presses should keep the gap.            

 (5)  In order to ensure the safety of the operation, attention should be paid to the seals and joint parts. 

 (6)  Where there are acid, alkali or corrosive gases, it is not suitable for hydraulic jacks.
