Why is my telescopic bollard sticking or hard to lift?

If your telescopic bollard is sticking or difficult to lift, it’s usually caused by debris, lack of lubrication, water build-up, or misalignment. The good news is most issues are easy to fix with basic maintenance.

Common causes

Dirt and debris
Mud, grit, and leaves can collect inside the ground sleeve, restricting movement.

Water build-up
Standing water can lead to stiffness, corrosion, or freezing in colder weather.

Lack of lubrication
Dry internal surfaces increase friction, making the bollard harder to operate.

Misalignment
If the sleeve or casing has shifted (often due to poor installation or ground movement), the post may bind when moving.

Quick fixes

• Clean around the top and inside the sleeve using warm soapy water
• Flush the sleeve with clean water to remove hidden debris
• Apply a light silicone or PTFE-based lubricant (avoid grease, as it attracts dirt)
• Raise and lower the bollard several times to distribute the lubricant

Prevention tips

• Carry out regular cleaning and light lubrication (monthly in high-use areas)
• Ensure drainage is working properly to prevent water build-up
• Avoid driving over the bollard when it’s partially raised
• Use a tight-fitting cap or cover to keep debris out

When to look closer

If the problem persists, check for:

• Bent or damaged internal components
• Severe corrosion inside the sleeve
• Installation issues (e.g. the unit not sitting perfectly vertical)

Practical takeaway

Most sticking issues come down to dirt, water, or lack of maintenance. Keeping the sleeve clean and lightly lubricated will usually restore smooth operation.
