Dump Trailer Hydraulic Oil: How to Choose the Best

Dump trailer hydraulic oil is a type of hydraulic oil used in the operation of dump trailers. It is a light, high-viscosity hydraulic oil with good cold flow properties.

It comes in various grades depending on the application. For example, for use in buses and dump trailers, it would be a grade A product, while for use in aircraft, it would be rate B. Dump trailer hydraulic oil is used to lubricate the gearbox and other moving parts that are exposed to dirt and debris from the ground during unloading operations.

Get to Know Hydraulic Oil

Hydraulic oil is a type of fluid that is used to transmit power from one place to another. It is also known as hydraulic fluid, a lubricant for hydraulic machines.

Hydraulic fluids are composed of four main components: oil, water, solid particles (grit), and gas bubbles (air). It is a liquid-based lubricant used in hydraulic machinery, such as pumps and motors. It provides the required amount of shear force to the moving parts to ensure smooth movement.

The Use of Hydraulic Oil for Dump Trailer

Hydraulic oil is responsible for facilitating a great deal of the essential functions your vehicle can perform. Different fluids are needed for specific purposes, such as when the conditions in which they will be operating. When choosing a fluid, you want to ensure it is suitable for your needs and is prepared to handle the characteristics of your system in terms of viscosity and wear resistance.

It also impacts the performance of various features: power transmission, lubrication, heat dissipation, debris transport, contamination, and sludge formation.

Dump trailers are enormous, heavy vehicles that require a lot of oil to keep them running smoothly. The oil is usually stored in a tank on the back of the truck and fed through an oil pump to all the moving parts. The oil can also be stored in other tanks throughout the dump trailer, but these tanks must be filled by hand or using an external pump.

To empty these tanks, dump trailers have a set of hoses that run from each tank  to an external hose reel mounted on the back of the dump trailers. The hoses are then connected to a series of quick-disconnect couplings that allow workers to disconnect and reconnect them as needed quickly.

Which Hydraulic Oil to Use in a Hydraulic System?

It does not matter what type of hydraulic oil you use as long as the viscosity grade (or thickness) is correctly matched to the operating temperature range of your hydraulic system.

There are a lot of different factors to keep in mind when choosing the correct fluid viscosity for your hydraulic system. The main factors affecting how viscous the fluid is, shaft speed, temperature, and operating pressure, affect how much energy should be added to the system.

There are different grades of hydraulic oils present in the market. Before selecting one for your vehicle, you must understand its properties and uses. There are multigrade or monograde, detergent or no detergent, and Anti-wear or R&W.

Multigrade or Monograd

If your hydraulic systems are required to work in both freezing and summer weather, you may need multigrade oil to keep the viscosity at an allowable level.

You’ll conserve fuel and money by using multigrade oil on your hydraulic systems while maintaining the viscosity range of 25-36 centistokes. It’s suitable for equipment operators, business owners, and the environment.

Anti-wear or R&W

The purpose of anti-wear additives is to maintain lubrication under harsher conditions. The most common anti-wear additive in engine and hydraulic oils is Zinc Dialkyl Dithiophosphates or ZDDPs.  As the discussion around the environment is becoming more prominent, “heavy” metals are getting a lot of attention as potential pollutants.

There are some negatives associated with using ZDDPs as a metal degreaser. For example, it can affect some metals and weaken or reduce oil viscosity (making it harder to filter). Stabilized ZDDPs chemistry has primarily overcome these shortcomings, making it an essential additive to the fluid used in any high-pressure, high-performance hydraulic system.

The additive is suitable for various engine types, including piston pumps and motors. According to some OEMs, an average concentration of 900 parts per million can be helpful in mobile applications.

What Kind of Hydraulic Oil Do I Use for My Dump Trailer?

Use high-quality industrial hydraulic oil for your heavy vehicles, like dump trailer trucks. Avoid low-grade/non-foaming juice as it will not provide the necessary protection to avoid corrosion and wear& tear.

What Is Non-foaming Fluid?

Non-Foam Hydraulic Oil AW is typically a zinc-containing, anti-wear hydraulic oil. The product features excellent wear resistance, rust, and corrosion prevention and offers thermal breakdown protection. These qualities also separate healthy water from gas while protecting foaming and filterability.

They are available in 32-46 and 68 ISO grades. L-HM Hydraulic Oil is a high-quality hydraulic fluid oil. Sinopec Anti-wear Hydraulic Oil ISO VG 46 is a premium oil for heavy equipment with an ISO VG rating 46with a low pour point and excellent anti-wear characteristics, perfect for industrial or equipment applications. It

t’s a hydraulic fluid that is rust and oxidation inhibited and contains an anti-wear additive package. It has been approved for industrial applications requiring ISO VG 46.

Why Use Anti-foaming Fluid?

There are many solid reasons for using these fluids. Some of them are listed below:

The excellent anti-wear and abrasion performance of the fluid prolongs the service life of your pump and all parts of your whole hydraulic system.

  • They have standard oxidation stability.
  • Good anti-corrosion and anti-rust performance
  • Have good adaptability for seals that effectively prevent oil from leaking.

How to Choose the Hydraulic Oil for Dump Trailer

There are many different types of hydraulic oil for dump trailers. Some are used for specific applications, and others for general use. You need to know your application, budget, and needs to get the best hydraulic oil.

The best oil for a dump trailer is compatible with the environment, has good lubrication properties, and is cost-effective.

The most important thing to consider when choosing an oil dump trailer is compatibility. This means that the oil should not be corrosive and should not contaminate the ground or water. The best oils are also compatible with other fluids like hydraulic fluid.

Oil selection can be tricky because there are so many factors to consider, but it’s worth taking the time to find the right one.

When choosing the right oil for your dump trailer, consider what type of vehicle you will be pulling with it and what terrain you will be driving on. You also need to ensure that your tank has enough oil capacity and that your engine requires the correct grade.

If you want to purchase a new hydraulic system, always check with your dealer if they have any specific recommendations on which oils to use with their products.

What Is the Difference Between AW32 and AW46?

The fluid is judged by its viscosity, meaning how well it can flow at different temperatures. AW oil is the best choice for heavy machinery because it resists wear and tears better than other oils. But, you may come across a question: “which is better, AW32 or AW46?”

There is no clear answer on which of these two types is better or worse.

The main difference between AW32 and AW46 hydraulic fluid is that AW32 is a 10-weight fluid, and AW46 is a 20-weight fluid. The lower the number, the thinner the oil, and the more easily it flows. The numbers do not refer to the quality but are solely a measure of fluid viscosity.

For Atlas above-ground lifts, AW-32 will flow better in colder weather than AW-46. Customers in cold climates with unheated garages may want to use AW-32. Above-ground lifts in heated garages (or warmer temperatures) may use AW-46 instead.

Things to Consider When Choosing Dump Trailer Hydraulic Oil

Although no fluid is ideal, selecting the best compromise for a particular system is possible. This requires knowledge of the system in which a fluid will be used.

The designer should know system characteristics such as maximum and minimum operating and ambient temperatures, pumps used, operating pressures and cycle, loads encountered by all components, and control and power valve types. 

Other than this, there are some key factors that you must consider while choosing the fluid for your hydraulic system.

  • Viscosity: The fluid’s viscosity can be increased to help it maintain a consistent level of friction, regardless of the fluid’s operating temperature. For this to happen, the maximum and minimum operating temperatures should be known. When filtering fluids, one must also remember that their viscosity is subject to change based on their operating temperature.
  • Wear: Hydraulic systems are prone to wear, but if you only think of it in friction, you’ll start believing that hydraulic systems never need service.
  • Corrosion: Your system needs corrosion protection to avoid breakdown and scathing attacks on metals. You should use additives that are water-stable and capable of protecting against corrosion.

These are the three main key factors: water retention, seal compatibility, fluid life, and disposability.
