Gas struts, sometimes called gas springs or gas lift supports, play an essential role in our everyday lives. They’re found in cars, furniture, and even industrial equipment, helping us lift and hold heavy objects with ease. But what happens when one gets stuck open? This guide explains why it happens, how to fix it, and how to prevent it in the future.
What are gas struts and how do they work?
Gas struts are clever little devices that use compressed gas and oil to create a smooth lifting and holding motion. Here’s a quick breakdown of their key parts:
- Piston rod: the part that moves in and out of the cylinder to transfer force.
- Cylinder: a sealed tube that holds the pressurised gas and oil.
- Seal: prevents leaks and keeps everything working properly.
When functioning as they should, gas struts make movement easy and controlled. However, when they get stuck open, they can become a real headache.
Why does a gas strut get stuck open?
Gas struts can get stuck for various reasons. Knowing the cause is the first step to solving the problem:
- Pressure imbalance: the internal gas pressure needs to be perfectly balanced. If it’s not, the strut might get stuck in one position.
- Dirt and debris: dust and dirt can build up over time, stopping the piston rod from moving smoothly.
- Damaged seals: the seals inside the cylinder are vital for maintaining pressure. If they’re worn or damaged, the strut won’t work properly.
- Overloading: using a strut to lift something heavier than it’s designed for can cause it to overextend and become stuck.
- Manufacturing defects: sometimes, a faulty strut straight from the factory can cause problems after only a short period of use.
Step-by-Step troubleshooting guide
If your gas strut is stuck open, don’t worry. Follow these steps to figure out what’s wrong and fix it:
- Look for visible damage: check the cylinder and piston rod for cracks, dents, or bends. Leaking oil around the seals is another sign of trouble.
- Clean the strut: wipe away any dirt or grime with a clean cloth. For stubborn spots, use a mild cleaning solution and dry the rod completely before testing it.
- Test the movement: gently push the piston rod to see if it moves. If it’s stiff or doesn’t budge, there might be an internal issue.
- Check the load: make sure the strut is designed to handle the weight you’re using it for. If it’s too weak, you might need a stronger replacement.
- Add some lubrication: use a silicone-based lubricant to reduce friction on the piston rod. Just be careful not to use too much, as excess grease can attract more dirt.
- Inspect the mounting hardware: loose or poorly aligned brackets can affect how the strut performs. Make sure everything is secure and aligned.
How to fix a stuck-open gas strut
Once you’ve identified the problem, try these solutions:
- Adjust the pressure: if the internal pressure is off, it might need to be adjusted. This is a job for professionals, as improper handling can be dangerous.
- Replace the seals: damaged seals can often be swapped out with a repair kit. Follow the manufacturer’s instructions to ensure a proper fit.
- Reposition the strut: changing the angle or alignment of the strut can sometimes solve the problem.
- Get a new strut: if all else fails, replacing the gas strut might be the best option. Be sure to buy one that matches the size and weight requirements of your application.
Preventing future problems
Regular maintenance can go a long way in keeping gas struts working smoothly. Here are some tips:
- Keep them clean: wipe down the struts regularly to prevent dirt from building up.
- Use the right lubricant: a light application of silicone-based lubricant will keep the piston rod moving smoothly.
- Check for wear and tear: inspect the struts and mounting hardware for damage or wear, and address any issues quickly.
- Match the right strut to the job: always use a gas strut that’s designed for the weight and size of your application.
- Avoid overloading: don’t exceed the weight capacity of the strut. Overloading can cause permanent damage.
When to call a professional
If you’re not comfortable fixing a gas strut yourself or the problem is too complex, it’s a good idea to get help from a professional. They can safely adjust the pressure, replace parts, and ensure everything is working as it should.
