Noisy, grinding or jerky gate
Grinding, squealing or jerky movement usually comes from worn gear sprockets, loose hardware, poor alignment, or worn wheels and track on a slide gate. On swing gates, a loose or flexible arm can make the gate surge. Look for loose bolts and visible damage, and call a gate company if anything is bent, cracked or needs welding. Sources: Elite Gates, Apollo.
Likely causes
- Worn gear sprockets.
- Loose hardware or poor alignment.
- Worn wheels or track on slide gates.
- On swing openers, a loose or flexible pivot arm can cause "surging" (Apollo).
Safe checks you can do
- Look for loose bolts and visible damage to wheels, track and brackets (Elite Gates).
- With the power off and the operator released, move the gate by hand to feel for binding (Mighty Mule gate opener maintenance guide).
- Lubricate the gate and moving parts with silicone spray every 3 months, as Mighty Mule suggests; grease ball bearing hinges every 2 months in coastal salt air (Mighty Mule gate opener maintenance guide).
When to call a gate company
- Anything is bent, cracked or needs welding.
- The noise comes from inside the operator.
- The gate binds when you move it by hand.
