Two post jack mainly used in lifting, lifting equipment for car maintenance, lifting weight, and designing according to customer requirements, for example, lifting 3ton, 5ton, 8ton, 10ton, 15 ton... and so on
Features
Simple structure, small size, light weight, high strength The strength and fatigue design according to load and frequency analysis, hydraulic cylinder material of special material, and special welding technology are used to detect by ultrasonic flaw detection. As a high-pressure specification, it achieves small size, light weight, high strength and high reliability. .
Sealing system
Relying on a unique sealing system designed to overcome the special field conditions of the two post jack, prevents destructive pollution of hydraulic cylinders by soil dust. While thoroughly solving the leakage outside the hydraulic cylinder, the piston rod is ensured to obtain the best lubricating oil film, which prolongs the service life of the sealing.
Cylinder Body
Use special materials to achieve good surface finish and hardness through cold extrusion and tumbling. It has achieved lightweight and high pressure design requirements.
Piston rod
Based on medium frequency quenching, the corrosion resistance of the piston rod is improved by double-layer bimetal plating (hard chrome plating + nickel plating).
Safety
Various valves having functions such as dedicated slow return count balance

FAQ
South Africa customers consulted with us about two post jack
Q: How does the control the quality?
A: 1)During processing, the operating machine worker inspect the each sizes by themselves.
2)After finished the first whole part, will show to QA for full inspection.
3)Before shipment, the QA will inspect according to ISO sampling inspection standard for mass production. Will do 100% full checking for small QTY.
4) when shipping the goods, we will attach the inspection report with the parts.
Q: PLC+inverter+motor+pump+solenoid valve+cylinder combination can control the position accuracy of the cylinder?
A: 1. Hydraulic oil can be compressed. It is elastic like a spring. Therefore, in a general hydraulic servo system, the valve control is much more accurate than the pump control. Because the valve can be mounted close to the hydraulic cylinder, even on the hydraulic cylinder, the pump must pass through the oil pipe and then enter the hydraulic cylinder, which has a long distance, which greatly reduces the rigidity of the system and increases the difficulty of control.
2. The dosing pump is leaky first, and there is also a 10%-20% flow pulsation. Pump leakage is related to pressure and is non-linear.
