The distinctive feature of the dumper trucks on comparison with the other kinds of truck machinery is independent unloading ability. For this purpose, they are equipped with the mechanisms overturning the body.
The body as a rule is inclining with the hydraulic equipment. This is the device that has the best operational features, high reliability and running rate.
Depending on the application field of the dumper trucks, different kinds of the hydraulic cylinders are set. However, the structure of all the devices includes a liner, a piston (plunger), a rod, a cover, a mud wiper, seals.
Under the impact of the hydraulic liquid, the plunger performs to-and-fro motions relative to the internal surface of the liner. Due to this the lifting device is put into operating.
The hydraulic cylinders are constantly on-load, and influence operational safety of the machinery. That’s why it is necessary to apply the most efficient methods to extend service lifetime of the components.
One of the factors significantly reducing service lifetime of the hydraulic cylinders is increased friction between the internal surface of the liner, and the plunger. These mated parts get worn, and the entire system fails.
o prevent wearing, MODENGY 1014 anti-friction solid-film coating is applied onto the plungers of the dumper truck hydraulic cylinders. It forms a thin smooth film on the surface of the parts that reduces friction and wear of the contacting elements, provides corrosion protection, and thus, extending service lifetime of the lifting mechanisms.
This product is applied by the standard painting methods onto the preliminary prepared surface of the parts, and polymerizes at heating in a kiln.
Use of MODENGY 1014 coating also reduces starting effort of the plungers at the temperatures below zero, improves smoothness of their moving, and prevents stick-slip motion.
