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
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,
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, 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
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.
