Hydraulic Fluid is the single essential product in the entire hydraulic system. The option of hydraulic oil varies according to the hydraulic system and application. One can pick from a range of oils like automatic transmission fluid, multiple grade engine oil, or anti-wear hydraulic oil.


In a truck crane, hydraulics are accountable for increasing and lowering the boom, extending the boom in a telescopic crane, controlling the steering, and outriggers, and adding and removing counterweights.


What is one of the best threats to your boom truck’s hydraulics? The cleanliness of the fluid.


Tiny Particles Can Create Big Damage


The research included some attention-getting statistics data:

  • Between 70% and 80% of hydraulic equipment, failures can be credited to hydraulic fluid cleanliness or lack thereof.
  • Particles that are as tiny as 2 microns can cause troubles in a hydraulic system.
  • The most harmful particles are between 3 and 20 microns in size. These tend to escape standard fluid filters.


Instead of oil analysis screening, the report suggests bit count testing which can discover particles as small as 2 microns. Since particles, less than 10 microns can trigger 3 1/2 more times damage than particles larger than 10 microns, it is important to use the more sensitive test on your hydraulic oil.


Choosing the Ideal Hydraulic Fluid

Though choosing the ideal hydraulic oil is a little challenging. Here are a few tips that can help you to pick hydraulic fluid.


Multiple Grade/Mono Grafe Oil

The hydraulic system is needed to operate in low temperature or tropical conditions after that it is advised to use multiple grade oil to maintain the viscosity.

Detergent Oil

Detergent oils are best known for emulsifying water and dispelling and arresting other contaminants like sludge or varnish. Generally, DIN 51524; HLP-D fluids are the ones comprised of detergents and dispersants.
