Industrial Crane Oil Cylinder Lifting Chromed Hydraulic Cylinder
Hydraulic cylinder is both for single or double-acting applications
with heavy duty welded construction. Cylinder’s standard color is
black, orange or as per requirement. In addition, all seals are
manufactured to US specification, and being 100% hydro-pressure
tested before delivery. Rod surface treatment is for chrome plated
or as per requirement. Hydraulic cylinder’s standard is B type
piston (optional: A type piston).

hydraulic cylinder common problem
1. Improper operation caused by the user cylinder or cylinder
deformation (overturn, cylinder by external impact, the use of
emergency brake unloading, etc.)
2. the cylinder bore internal fine particles produced after the
arrest of the guide ring, causing chaos cylinder.
3. missing (welding) limit plate limit valve failure.
4. Limit valve internal failure caused by cylinder out of line.
5. To improve the trip, the user adjusts the limit valve stem
without permission, causing the limit valve failure caused by
dislocation of the cylinder rod or stuck.
6. Limit valve stem cannot return caused by fuel tank stuck.
Control of hydraulic system leakage control program
1. The choice of hydraulic components often plays a decisive role
in the leakage of the hydraulic system
2. This determines our technical staff in the new product design,
the improvement of old products, dump truck hydraulic lifting
system custom,
3. The choice of cylinder, pump, valve, seal, hydraulic accessory,
etc., The principle of selecting the best, choosing the best and
the cheapest will be prudent and comparative
