Forklift Hydraulic System Problems: 5 Warning Signs & Repair Costs

Hydraulics are one of the most important systems of a forklift, because they control the machine’s lifting and lowering power, as well as the stability of each load. Even small issues can turn into major hazards, and also cost money because of unnecessary downtime when the equipment is out of order.

Not only do you need to know how to recognize forklift hydraulic system problems in the earliest stages. But it’s also essential to stay ahead of routine maintenance so that you can avoid bigger complications in the future. With the right approach, you can maintain the equipment and keep a productive work schedule for every shift.

How Forklift Hydraulic Systems Work

Even if you don’t know the technical details of a hydraulic system, it’s helpful to have a general idea about how this equipment works. There is pressurized hydraulic fluid that moves the forklift’s cylinders, which lift and lower the loads.

Some of the core components in the hydraulic system include the pump, hydraulic fluid, valves, and cylinders. If just one of these components fails, then it can have an impact on the whole system.

Five Warning Signs of Forklift Hydraulic Problems

All operators and team members need to be trained on these warning signs to ensure safety in the workplace. Regular inspections are non-negotiable. If any of these forklift hydraulic problems are identified, then the equipment should not be used until it can be repaired.

1. Slow or Jerky Lift Movement: A good hydraulic system will move smoothly. So, if you notice any slow or jerky movements, then it’s a sign that something is wrong. Pay attention if the load is lifting unevenly or the machine hesitates. Usually, these issues are caused by a loss of pressure or internal wear and tear.
2. Hydraulic Fluid Leaks: Check around the equipment to see if there is any fluid on the floor. When visible drips or puddles are present, it’s a warning sign that something is wrong. Don’t use the machine if you see signs of hydraulic leaks in forklifts, because it’s an indication that you might have failing seals or worn hoses.
3. Unusual Noises: When you’re using a forklift regularly, you are familiar with the normal sounds. Pay attention to any unusual noises, especially when they are coming from the pumps or valves. Warning sounds might include whining or grinding. It’s possible that you might have air in the system or a pump that is wearing out.
4. Overheating Hydraulic Components: Temperature matters, which is why it’s a warning sign if you notice excess heat while using the equipment normally. Heat could be an indication of restricted flow or contaminated fluid. If you ignore this heat, then it could speed up the internal damage of the machine, costing a lot more money in repairs or replacement in the future.
5. Loss of Lift Power: Any time there is a change in the lifting power, stop using the machine immediately. For example, if you are lifting a rated load, there should be no issues with lifting power. When you notice that it is lifting slowly or unevenly, then it could be an indication of advanced issues, such as forklift hydraulic cylinder problems.

Common Causes of Hydraulic System Failure

Every machine is different, which is why there’s not a cookie-cutter solution to fix forklift hydraulic system problems. But there are some common reasons that might impact the performance of the machine, such as:

• Wear and tear of the hoses and seals
• Fluid that is dirty or contaminated with moisture
• A malfunction of the pump or valve
• Air is trapped in the hydraulic lines
• Issues with pressure regulation

An Overview of Forklift Hydraulic System Repair Costs

How much money should you expect to spend on forklift hydraulic system repair services? It depends on the type of machine and the damage that needs to be fixed. Repair expenses are typically much lower when you are proactive about addressing issues in the earliest stages.

It’s much cheaper to invest in minor fixes and regular maintenance instead of waiting for system-wide failure. Talk to our team for personalized recommendations so that we can help you keep the equipment in the best condition possible.

• Minor Repairs vs. Major Repairs: Small repairs, such as seals or fittings, are much more affordable compared to major repairs for multiple components (especially when the pumps or cylinders are involved).
• Hose and Fitting Replacement: One of the most common needs for a forklift hydraulic system repair is to replace the hose and fitting. The good news is that this is an affordable repair when it’s caught early.
• Hydraulic Pump or Cylinder Repairs: These types of repairs can be more expensive, especially when you add up costs for both labor and parts. If you notice a loss of pressure, then it’s likely that these repairs are necessary.
• Full System Repairs: If a forklift has been neglected or routine maintenance has been skipped, then there is a higher likelihood that full system repairs will be necessary. Even though you’ll need to invest money into the expensive repairs, it’s worth the cost to restore the reliability of the machine.

When to Call a Professional Technician

Some maintenance tasks can be handled by your crew, but you shouldn’t hesitate to call a forklift technician for other types of repairs and maintenance. We recommend that you contact our team as soon as possible if your machine is leaking, overheating, or losing power. All of these issues can be addressed and should be taken care of immediately to avoid safety issues.

Whenever there is an issue that affects the forklift’s load handling, you need to act quickly to avoid hazards and danger. Even seemingly minor problems can quickly escalate into serious threats, which is why it’s essential to be proactive about taking care of your equipment with maintenance and repairs.

The Cost of Ignoring Hydraulic Problems

Not only do hydraulic issues increase the risk of accidents, but the other costs are not worth it. For example, your repair expenses will increase over time if you are not proactive about maintenance and early intervention repairs. Additionally, failing to keep up with the necessary repairs will reduce the lifespan of your forklift.

FAQ

Can you operate a forklift with a small hydraulic leak?

If you suspect a hydraulic leak, then the forklift should not be operated until it is repaired. Hydraulic leaks cause a safety threat. When left untreated, a leak will result in more damage to the equipment.

How often should forklift hydraulics be inspected?

A forklift hydraulic system should be checked daily. It’s an essential part of regular inspections and maintenance.
