Common Issues
Hydraulic leaks can cause a liftgate to malfunction, so it's essential to have a technician inspect and repair the hydraulic system promptly if you notice slow operation or leaking fluid.

Electrical problems, such as a malfunctioning motor or faulty wiring, can also cause a liftgate to stop working altogether, requiring a trained technician to diagnose and fix the issue.
Mechanical failures, like wear and tear on hinges, lifting arms, or the platform itself, can lead to operational issues, and these parts need to be repaired or replaced to restore the liftgate's functionality.
Some common problems with commercial truck lift gates include a liftgate not opening at all, which can be caused by a broken spring or other component within the liftgate assembly.
A liftgate not closing completely can be caused by worn out components, such as hinges, springs, or cables, which our expert technicians will make sure are working properly before leaving your property.
Pneumatic lift gates can encounter issues like air leaks or malfunctioning valves, which require identifying and sealing air leaks, repairing or replacing valves, and ensuring proper air pressure and flow.
Here are some common liftgate issues and their causes:
Pump Failures:

Pump failures can be a real headache, but understanding the common issues that cause them can help you prevent or fix the problem.
Repairs for pump failures may entail motor replacement.
In some cases, overheating issues can lead to pump failures.
Repairing or replacing damaged valves is often necessary to get the pump up and running again.
Pneumatic Issues:
Pneumatic issues can be a real pain to deal with. Pneumatic lift gates use air pressure for operation and can encounter issues like air leaks or malfunctioning valves.
Repairing pneumatic lift gate issues involves identifying and sealing air leaks. This is often a straightforward process that can be done with the right tools and some basic knowledge of how the system works.
Malfunctioning valves can be a bit more tricky to fix, but it's usually just a matter of replacing the faulty valve with a new one. Proper air pressure and flow are also crucial to ensure the lift gate operates smoothly.
Air leaks can be caused by worn-out seals or damaged hoses, so inspecting these areas is essential when troubleshooting pneumatic lift gate issues. By taking the time to properly repair or replace these components, you can get your pneumatic lift gate up and running in no time.
