How to Fix Sliding Driveway Gate Chains

Driveway gates are an excellent addition to any home, providing added security and style to your property. However, a sliding driveway gate can be challenging to operate if the chain becomes loose or comes off the track altogether. If you’re experiencing problems with your sliding driveway gate chains, you’ve come to the right place. In this article, we’ll discuss how to fix your sliding driveway gate chains so that it operates smoothly and efficiently.

1. Inspect the Chain

The first step in fixing a sliding driveway gate chain is to inspect it carefully. This will help you determine the root cause of the problem. Check the chain thoroughly for signs of wear and tear or damage, such as rust or broken links. If you find any issues with the chain, you’ll need to replace it.

2. Adjust the Tension

If the chain is in good condition, the next step is to adjust its tension. Loose chains are often the culprits behind the sliding gate’s malfunctioning. Follow these steps to make the adjustment:

Step 1: Remove any obstacles that are blocking your access to the chain.

Step 2: Turn off the power of the gate, if it’s an electric one. It’s best to turn off the power and unplug it completely from the power source to avoid electrocution.

Step 3: Locate the chain tension adjuster on the gate. If you’re having trouble finding it, check the manufacturer’s manual.

Step 4: Use an adjustable wrench to loosen or tighten the tension adjuster bolt. To tighten, turn the bolt clockwise or counterclockwise for loosening.

Step 5: Once you get the desired tension on the chain, use a wrench to lock the tension adjuster bolt securely.

Step 6: Turn the gate on and see if the issue is gone.

3. Lubricate the Chain

One of the reasons why a sliding driveway gate might malfunction is because of the lack of lubrication. Over time, the chain may become dry or rusty, making it challenging to move. Lubricating the chain can help fix this problem.

Step 1: Turn off the power supply of the gate.

Step 2: Use a stiff wire brush to remove any dirt, old grease or rust from the chain.

Step 3: Apply a recommended lubricant to the chain. Before lubricating, check the manufacturer’s manual for the recommended type of lubricant. Apply in small amounts at a time, and wait for it to settle on the chain.

Step 4: After lubrication is done and settled, turn on your gate and check the movement.

4. Check the Chain Alignment

If the chain is still not functioning correctly after adjusting the tension and lubricating it, checking the chain alignment might be the best solution. Incorrect chain alignment can cause the chain to come off the track, making it hard to open or close the gate. Follow these steps to fix the chain alignment:

Step 1: Go to the end of the gate where the chain comes off the track.

Step 2: Loosen the tension bolts on the rollers to shift them to the correct positioning of the track.

Step 3: Adjust the alignment until smooth movement of the chain is achieved.

Step 4: Tighten the bolts securely to fix the new alignment.
