Top 5 Construction Heavy Machines Prone to Hydraulic Cylinder Failure
We've compiled the top 5 heavy construction equipment that most often have hydraulic system problems. Check it out!
Construction equipment relies heavily on hydraulic systems to perform various tasks, from lifting and digging to grading and hauling. These hydraulic systems, powered by hydraulic fluid pressure, convert hydraulic energy into mechanical energy so the equipment can tackle demanding jobs.
However, hydraulic cylinders are a critical component of these systems and are prone to failure due to factors such as fluid contamination, improper maintenance, and extreme temperatures. This article by our team at Cylinders, Inc. will discuss the top five types of construction heavy machines prone to hydraulic cylinder failure and explore the causes, prevention, and maintenance of these issues.
1. Excavators: The Backbone of Construction Sites
Excavators rely on hydraulic cylinders to power the boom, arm, and bucket, enabling them to dig, lift, and move materials efficiently. These cylinders offer the necessary force and precision needed for excavators to perform their tasks effectively in harsh working conditions.
Most frequent reasons/causes for breaks:
Fluid contamination due to dust, dirt, and debris.
Worn or damaged seals and piston rods.
Overloading or excessive stress on the hydraulic system.
Improper maintenance or lack of regular servicing.
Troubleshooting guide:
Check for leaks or visible damage to the hydraulic cylinders.
Monitor the excavator’s performance for reduced power or efficiency.
Inspect the hydraulic oil for signs of contamination or degradation.
Listen for unusual noises or vibrations during operation.
Maintenance tips to avoid downtime:
Perform regular fluid filtration and replacement.
Keep the excavator clean and free of debris.
Inspect and replace worn seals and piston rods as needed.
Follow the manufacturer’s recommended maintenance schedule.
Use high-quality hydraulic fluid and filters.
2. Loaders: Moving Mountains, One Scoop at a Time
Loaders, such as wheel loaders and skid steer loaders, use hydraulic cylinders to lift and tilt the bucket, allowing them to move large amounts of material quickly and efficiently. These cylinders have the needed power and control for loaders to perform their tasks effectively.
Most frequent reasons/causes for breaks:
Scored or damaged cylinder rods due to misaligned mountings, inadequate lubrication, or abrasive particles in the hydraulic fluid.
Worn or damaged seals, leading to leaks and reduced performance.
Overloading or excessive stress on the hydraulic system.
Improper maintenance or lack of regular servicing.
Troubleshooting guide:
Check for leaks or visible damage to the hydraulic cylinders.
Inspect the cylinder rods for scoring or wear.
Monitor the loader’s performance for reduced lifting capacity or speed.
Check the hydraulic fluid level and condition.
Maintenance tips to avoid downtime:
Ensure proper installation and alignment of the hydraulic cylinders.
Perform regular lubrication and fluid maintenance.
Inspect and replace worn seals and cylinder rods as needed.
Follow the manufacturer’s recommended maintenance schedule.
Use high-quality hydraulic fluid and filters.
3. Backhoe Loaders: The Swiss Army Knife of Construction
Backhoe loaders are versatile machines that combine the functionality of an excavator and a loader. They rely on hydraulic cylinders to power the boom, arm, and bucket of the excavator, as well as the loader’s lift and tilt functions. This makes them ideal for a range of construction tasks.
Most frequent reasons/causes for breaks:
Seal failure due to extreme temperatures, fluid contamination, or improper maintenance.
Worn or damaged piston rods and bearings.
Overloading or excessive stress on the hydraulic system.
Improper operation or lack of operator training.
Troubleshooting guide:
Check for leaks or visible damage to the hydraulic cylinders.
Monitor the backhoe loader’s performance for reduced power or efficiency.
Inspect the hydraulic fluid for signs of contamination or degradation.
Listen for unusual noises or vibrations during operation.
Maintenance tips to avoid downtime:
Use high-quality seals and regularly inspect and replace them as needed.
Perform regular fluid filtration and replacement.
Inspect and replace worn piston rods and bearings as necessary.
Follow the manufacturer’s recommended maintenance schedule.
Provide proper operator training to avoid overloading or improper use.
4. Bulldozers: Moving the Earth with Raw Power
Bulldozers are heavy-duty machines that rely on hydraulic cylinders to control the blade. They provide the necessary force to push and move large amounts of soil, rock, and debris. These cylinders allow bulldozers to perform their tasks effectively in extreme working conditions.
Most frequent reasons/causes for breaks:
Fluid contamination due to harsh working environments, leading to damage to cylinders and other components.
Worn or damaged seals and piston rods.
Overloading or excessive stress on the hydraulic system.
Improper maintenance or lack of regular servicing.
Troubleshooting guide:
Check for leaks or visible damage to the hydraulic cylinders.
Monitor the bulldozer’s performance for reduced power or efficiency.
Inspect the hydraulic fluid for signs of contamination or degradation.
Listen for unusual noises or vibrations during operation.
Maintenance tips to avoid downtime:
Maintain a clean hydraulic system by regularly replacing filters and fluids.
Keep the bulldozer free of debris and clean the hydraulic components regularly.
Inspect and replace worn seals and piston rods as needed.
Follow the manufacturer’s recommended maintenance schedule.
Use high-quality hydraulic fluid and filters.
5. Dump Trucks: Hauling Heavy Loads with Hydraulic Power
Dump trucks rely on hydraulic cylinders to lift and lower the dump bed, allowing them to quickly and easily unload their cargo. These cylinders provide the necessary power and control for dump trucks to transport large amounts of materials efficiently.
Most frequent reasons/causes for breaks:
Overloading or exceeding the truck’s rated capacity, leading to excessive stress on the hydraulic cylinders.
Worn or damaged seals and piston rods.
Fluid contamination due to harsh working environments.
Improper maintenance or lack of regular servicing.
Troubleshooting guide:
Check for leaks or visible damage to the hydraulic cylinders.
Monitor the dump truck’s performance for reduced lifting capacity or speed.
Inspect the hydraulic fluid for signs of contamination or degradation.
Listen for unusual noises or vibrations during operation.
Maintenance tips to avoid downtime:
Make sure the truck is loaded within its rated capacity.
Perform regular inspections and maintenance on the hydraulic cylinders.
Replace worn seals and piston rods as needed.
Maintain a clean hydraulic system by regularly replacing filters and fluids.
Follow the manufacturer’s recommended maintenance schedule.
Preventing Hydraulic Cylinder Failure: Best Practices
While hydraulic cylinder failure is a common issue in construction equipment, there are several best practices that can help prevent these failures and extend the life of the hydraulic system.
Our team has outlined what you need to know:
Regular maintenance: Performing regular maintenance, such as fluid and filter changes, can help prevent contamination and ensure that the hydraulic system is operating at peak performance.
Proper operation: Operating the equipment within its rated capacity and avoiding overloading can help prevent excessive stress on the hydraulic cylinders.
Correct fluid selection: Using the correct type and grade of hydraulic fluid can help prevent contamination and ensure optimal performance.
Seal and component replacement: Regularly inspecting and replacing seals and other components can help prevent leaks and ensure that the hydraulic system is operating efficiently.
Regular inspections: Conducting regular inspections of the hydraulic system can help identify potential issues before they lead to failure, allowing for prompt repairs and maintenance.
Conclusion
Unfortunately, hydraulic cylinder failures are a common issue in construction equipment, with excavators, loaders, backhoe loaders, bulldozers, and dump trucks being particularly prone to these problems. However, a little bit of knowledge goes a long way. By understanding the common causes of hydraulic cylinder failure, such as fluid contamination, improper maintenance, and overloading, construction professionals can take steps to prevent these issues and extend the life of their equipment.
Regular hydraulic system maintenance, proper operation, correct hydraulic oil selection, hydraulic seal and component replacement, and regular inspections are all essential best practices for preventing hydraulic cylinders from failing.
