This applies to 75kg / m rail and below-rail-type operations, supporting operations with tamping machine for line maintenance, use three or more pairs of turnout or turnout swarm from the road, very good results lining jobs. 

YQD-245 Hydraulic Rail Jack Maintenance

1.In order to ensure that the hydraulic lifting machine each time you use flexible and reliable, it must perform effective maintenance and periodic inspections.
2. To ensure the hydraulic lifting machine sliding parts and exposed moving elements do not rust, such as the use of longer intervals, it must on the anti-rust oil, do not drop the machine, knock, bumps, in order to ensure that the machine activities accuracy.
3. Requires quarterly moving parts of the machine and carry out periodic checks oil.
4.Replace or supplement the hydraulic oil should be used for the 18-38 CST viscosity (oil temperature at 50 ℃) specification, which is not greater than 20 microns precision oil filter hydraulic oil. When not in the supplementary hydraulic oil mixed with sand and other debris. And note that each oiling pump must be vented.
5.When need to repair, the use of clean gasoline or diesel oil and the main parts and components, and do not damage parts.
