Forklifts depend on hydraulic fluid for their lifting and steering abilities. Hydraulics are the lifeblood of a forklift. Without it, you are increasing the chances of your forklift breaking down. Whether you are lifting 20,000 pounds or 1,000 pounds, a proper forklift relies on the perfect amount of hydraulic fluid to provide excellent production. An inadequate level of hydraulic fluid could decrease the functionality of your forklift’s lifting and steering ability. An Overabundance of fluid can cause leaks and spills, which could lead to safety and environmental dangers. Here is everything you need to know about adequately filling and checking hydraulic fluid for your forklift.

Filling hydraulic fluid into your forklift

There are specific steps and procedures to follow in regards to filling your forklift with hydraulic fluid. Correctly filling your forklift will help maintain the equipment in the future.

  1. Consult the operator manualWe recommend replacing a forklift’s hydraulic fluid every 1,000 hours of use. However, you should consult the forklift operator’s manual if available. It will provide the specific grade of hydraulic fluid use for your particular forklift along with the fill level of your hydraulic tank.
  2. Proper Parking – Please make sure the forklifts are parked on level ground and not on anincline. If not, you can run the risk of a hydraulic fluid leak or your forklift accidentally rolling. If you cannot park on level ground, please chock the wheels to prevent the forklift from becoming loose. Lower the forks until they touch the ground, set the parking brake, and turn the ignition off.
  3. The Hydraulic ReservoirOpen the hood and locate the hydraulic reservoir. It will have a vented fill cap with a sight glass or fill gauge on its side to indicate the fluid level.
  4. Provide the fluid – Remove the vented fill cap and insert the oil into the fill tube and begin pumping the liquid into the reservoir.
  5. Checking the levels –This step is very vital. Keep your eyes on the tank’s fluid level via the sight glass or fill gauge. The gauge contains a fill level that provides the proper capacity of oil for the forklift. Once the fluid reaches the max line, stop pumping.
  6. Withdraw the pump – Slowly remove the hydraulic delivery pump’s fill nozzle. Use a towel to clean up any fluid that may have spilled outside the tank.
  7. Finish the jobReplace the vented cap with a new one. Tightened the cap and closed the lid. You have correctly filled hydraulic fluid into your forklift.

3 Symptoms to watch for in case your hydraulic fluid is running low

Again, we recommend replacing a forklift’s hydraulic fluid every 1,000 hours of use. Still, sometimes it can be challenging to monitor all the forklifts in your fleet, especially if you run a forklift occasionally over time. Here are three easy detectable symptoms to be aware of when your hydraulic fluid is low.

Abnormal NoiseNatural elements can affect your hydraulic systems. Aeration occurs when air contaminates with hydraulic fluid. This can create a banging or knocking noise when it compresses and decompresses through the system. Ventilation can cause hydraulic fluid to accelerate the degradation of the liquid. If you begin to notice a knocking noise while operating your forklift, check your hydraulic gauge to ensure you are not running low.

Hydraulic Forklift

High Fluid TemperatureAnything can cause a high fluid temperature. If your fluid temperature exceeds 180 degrees, it can damage the seals and accelerate the liquid’s degradation. Not only could this cause your fluid to evaporate exponentially, but it could also damage the forklift due to its excessive thinning of the oil film. To notice if you have a high-temperature fluid, install an alarm in the system that can measure the fluid temperatures.

Slow OperationIf you begin to notice a significant drop-off in your forklift performance, you may need a hydraulic fluid change. The hydraulic fluid is the engine that keeps your forklift running in excellent shape. Therefore, a loss of speed can indicate a loss of fluid.

Proactively monitoring noise, fluid temperature, and operation can adequately detail the condition of your hydraulic fluid.

How to Check the Hydraulic Fluid Levels?

You noticed something is wrong with your forklift. Your equipment is making an abnormal noise, moving slowly, and it has been a while since you last filled your hydraulic fluid. It could be time to check your hydraulic fluid levels, but how?

  1. Gather your DipstickMany Original Equipment Managers (OEM) provide the same dipstick for various models. For example, cushion tire and pneumatic tire trucks use the same dipstick with masts ranging from single to triple. For pneumatic forklifts, use the side marked with P1, P2, P3. With cushion forklifts, use the side of the dipstick marked C1, C2, C3. Check out your operator manual for reference on which number to check or contact your local dealer.
  2. Park on level groundMake sure you position your forklift on an uneven or uphill surface.
  3. Keep your forks in a standard position – Lower the forks to the ground and not tilt them backward or forward. If elevated, some of the hydraulic fluid will be in the lift cylinders, and you will not be able to gather an accurate reading.
  4. Use the dipstick to check the level
  5. Use the correct fluidMake sure to use the recommended fluid by the manufacturer. Putting the wrong fluid in the equipment will lead to poor results.

Keep your machines running right with regular fluid checks, filter replacements, and routine inspections. Please keep track of your hydraulic fluid and make sure to replace it every 1,000 hours of use. For any more service questions, contact ourservice department.

Most people have heard of the term hydraulics for cars and other types of machinery, but few know what the hydraulic system is exactly and how it works.

Since its invention, the forklift hydraulic pressure system has helped people get difficult, heavy work done and create a force that we can’t produce on our own. If you are a heavy equipment operator, then it’s important to understand how these forces work and the different parts that go into them.

Different machines use the hydraulic system in different ways. In this post, we address the basis of this system, and more specifically, the forklift hydraulic system.

Whether your company uses forklift hydraulic pressure lifts or electric forklifts, OSHA compliant is mandatory. Without properly trained forklift drivers, your company is more susceptible to suffer accidents and injuries on the job.

The History of Hydraulics

French scientist Blaise Pascal discovered the principle behind the hydraulic system over 300 years ago. Pascal learned that liquid cannot be compressed. When pressure is put on a confined liquid, the liquid transmits pressure in all directions. Those are the basic principles behind the forklift hydraulic pressure system. For example, if a container holding liquid has an opening, the liquid will try to escape at a pressure that’s equal to the pressure put into the container.

In the late 1700s, British mechanic and engineer, Joseph Bramah, used Pascal’s principles to experiment on practical applications. In 1795, Bramah patented the first hydraulic press which became the basis for the modern-day hydraulic system.

In a way, you can say that 1795 was the dawn of the hydraulic forklift era, although actual forklifts were still more than a hundred years away. However, Pascal and Bramah showed the scientific field how a forklift hydraulic system works – or would eventually work, anyway!

Forklift Hydraulic System Explained

Hydraulics work by using pressurized fluid to power the engine of a car or machine. Hydraulic presses put pressure on a small amount of liquid to create a large amount of power.

The basics of the hydraulic system go like this: Confined liquid has pressure on it from one side. That pressure forces the liquid against a piston on the other side of the container. That transfers energy into the piston, forcing it upward. The piston cannot move in the opposite direction unless the pressure is released. In terms of the forklift hydraulic system, the pistons raise the forks and keep them lifted until the hydraulic pressure is released by the operator.

The Forklift Hydraulic System: How a Forklift Hydraulic System Works

In most forklifts, the tank is integrated into the frame of the vehicle. That’s what holds the hydraulic fluid.

Besides the tank, the components of the forklift hydraulic system include:

  • Pump: Produces a constant flow of hydraulic fluid to supply the control valve. Most forklifts use a gear-type pump. The pump consists of a pair of rotating gears that push the fluid in the opposite direction of the rotation.
  • Control Valve: Starts and stops the direction of fluid and controls where the fluid moves using spools. Without a control valve, forklift hydraulic pressure would be useless.
  • Relief Valve: Protects the hydraulic system from too much pressure. This part is considered a critical safety component of hydraulic forklift hydraulic pressure.
  • Return Line: Returns the fluid to the tank. The return line completes the forklift hydraulics cycle.

The types of fluids used in forklift hydraulic pressure include water-based fluids, petroleum-based fluids, and synthetic fluids. Water-based fluids are fire-resistant but do not provide as much lubrication as the other types. Petroleum-based fluids are customized to the hydraulic system with additives and are the most popular. Synthetic fluids are useful for high temperature and high-pressure systems.

How Do Hydraulics Work in a Forklift?

Using cylinders, the forklift hydraulic system works very similarly to the confined liquid example. The cylinders are sealed tubes with an inserted rod. As the hydraulic lines put pressurized fluid into the tube, the rod is pushed out as the fluid looks for the path of least resistance. Resistance is introduced to run the fluid through the hoses and connections on the different components that are powered via hydraulic pressure. Pioneer vsx 922 service manual.

Tubing pumps the hydraulic fluid into a reservoir. The pump creates the pressure that moves the fluid through the forklift hydraulic system.

Which Grade of Hydraulic Fluid Does a Forklift Use?

To determine which grade of hydraulic fluid a forklift uses, consult the lift’s operations manual. Here, you can find full details about the proper type of hydraulic fluid for a forklift, how often the fluid should be changed, and other pertinent information. If you cannot find the lift’s operations manual, use a general purpose fluid like ISO 32 hydraulic oil.

When it comes to hydraulic fluid for a forklift, stick to the recommendation included in the lift’s operations manual. Using the proper hydraulic fluid limits the risk of wear and tear on your lift.

How to Check and Fill Hydraulic Fluid in a Forklift

The hydraulic fluid reservoir is located under the hood of the lift. It has a vented cap on the top and sight cap or gauge to indicate how much hydraulic fluid is currently inside the reservoir.

Typically, a forklift’s hydraulic fluid needs to be changed after approximately 1,000 hours of equipment use. At this point, the lift should be parked on level ground, with the forks lowered to the ground, the parking brake set, and the ignition off. Next, remove the vented cap from the hydraulic fluid reservoir, insert the oil delivery pump’s discharge nozzle into the fill tube, and pump the fluid into the reservoir.

Do not overfill the tank, as doing so can impact the forklift’s steering and lifting abilities. When the tank is full, remove the delivery pump’s fill nozzle, and clean up any hydraulic fluid that may have spilled outside the tank.

Common Forklift Hydraulic System Issues

There are many problems that can affect a forklift’s hydraulic system, such as:

1. Mast Drift

Mast drift occurs when a lift’s mast changes position when elevated under load. The problem may seem minor at first. However, when left unaddressed, the issue can escalate quickly and cause a lift to tip over.

2. Hose Leak

Hydraulic system hoses are used to transfer fluid pressure. But, a hose deteriorates over time, and it can crack and leak. Other factors that can cause a hose to crack or leak include the use of an improperly fitted hose fitting or use of an incompatible type of hydraulic fluid.

3. Clogged Suction Filter

A suction filter can become clogged if it goes unchanged for an extended period of time. In this instance, the filter can no longer catch and remove contaminants from the hydraulic fluid. It can also stop the flow of hydraulic fluid.

How Are Hydraulic Problems Diagnosed?

There are several warning signs that forklift hydraulic problems may be present, including:

  • Strange noises from the lift
  • Hydraulic fluid temperature above 180°F (82°C)
  • Slow operation

At the first sign of any hydraulic problems, it is beneficial to diagnose and address these issues. This ensures that a forklift can be fixed or replaced before it can potentially put the health and wellbeing of lift operators in danger.

Why Are Hydraulics Important to Operate a Forklift?

Hydraulic

Forklift hydraulics raise the load-bearing prongs off the ground. A hydraulic forklift lifts and holds the load in the air while the forklift moves. A forklift hydraulic system is the heart of the machine because it is responsible for moving pallets. And the heart of your company’s safety program is proper hydraulic forklift training and certification! The levers control the hydraulic system in a forklift. The operator needs to be very careful with them. It’s important that only trained and certified operators use forklifts. They need to properly calculate the load and how much lift power is needed to move it. The hydraulics of a forklift have a lot of power, and only a small amount of effort can create enough force to move a large, heavy load.

The proper usage and maintenance of a forklift will keep the forklift hydraulic pressure system in good working condition, without needing constant repair work.
