Product Description

Product Introduction 
YQD-245 Hydraulic Rail Jack applies to 50kg / m, 60kg / m rail track, turnout from the road operations, increased by manually driven piston plunger pump, driven from the road levers so that jobs at the bottom of the rail track lifting lever front wheel quick lifting from the Road to achieve the purpose from the Road jobs.
YQD-245 Hydraulic Rail Jack is required an ideal for road on the mining service tool, suitable for rail rearrangement of homework.
YQD-245 Hydraulic Rail Jack mainly consists of hydraulic parts and lever parts. Hydraulic lifting machine main structural features: Hydraulic lifting machine with manual operation, no other power consumption, mainly through the manual lever on the side of the hydraulic drive machine hook for lifting movement, and thus play a role from the road, reasonable structure, carrying convenient, true-to-use mechanical. 
YQD-245 Hydraulic Rail Jack is the railway line from the lining repair special tools, jobs are not intrusive and bound, safe and reliable, in one machine, high efficiency, easy operation, reduce labor intensity. 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, Shang Hao oil must be used, 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 centistokes 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.
