    1. Hydraulic cylinder is the most important component in hydraulic systems, it will transfer hydraulic energy into mechanical energy, and is matched with various transmission mechanism, to complete a variety of mechanical motion. 2. Hydraulic cylinder has the advantages of simple structure, large output force, stable and reliable performance, easy maintenance, wide application.   3. Hydraulic support lifting jack is the main weight-bearing element which undertakes the movement of the hydraulic support and each part. The product is mostly single telescopic, double-act, piston type hydraulic cylinder, widely used in the hydraulic support for traction, side thrust, protection and assistance, balance, support adjustment, and etc.   4.Long stroke hydraulic cylinde can be used for dump truck, oil field, marine, drilling machine, industry, elevator , workover rig ,etc.     2.products showcase      3.prodecu line 700 sets manufacturing equipment,such as cold drawing production line ,heat treatment production line ,surface treatment production line,testing equipment,various digital-control machining equipment,gantry style linear electroplating production line.      4.Quality guarantee system   Program before Delivery 1. Trial Operation Test 2. Start-up Pressure Test 3. Pressure-Tight Test 4. Leak Test 5. Full Stroke Test 6. Buffer Test 7. Testing the Effect of Limit 8. Load Efficiency Test 9. Reliability Test Every piece of hydraulic cylinder are tested and will send out only after they are pasted the each test.   Our company has abundant technical force and perfect testing means. By making wide technical and business cooperation with many related enterprises, universities, colleges and institutes both at home and abroad, and employing senior engineers and software engineers, we have greatly strengthened and improved our designing, processing, and testing abilities.         5.certificates           6.factory overview     We are one of the biggest hydraulic cylinder manufacturer in China, specialized in design, R & D and manufacturing of hydraulic machinery products etc, with its annual production capaciy of 200000 sets.My company with 600 employees in it ,covers an area of 180000 square meters.There are 700 sets of mnufacturing equipment .   0ur company invested 10 million RMB in two cold drawing lines, one is 200 tons and the other is 320 tons with acid cleaning, phosphatization , heat treatment and alignment cutting.   Gantry style linear electroplating line is appropriate for copper, chrome, or zinc plating, aluminum oxidating, phosphorization electroplating of plastics, and other advanced technological requirements. And it can fulfill the functional and ornamental requirements according to the demands of customers. The whole line has the merits of rational structure, beautiful exterior. It is easy to operate and can be designed into full automatic-manual operation. The automatic operating system can be programmed and controlled by computer. The roller of gantry overhead crane is made of lactoprene and moves smoothly without noise. All working procedures can be monitored. With the frequency control, the soft lift, the to-and-fro speed of 4-40m/min, it is an automatic production line with wide adaptability, appropriate for coating baths of different dimensions.
