How to Easily Cut a Chain for an Electric Gate: Step-by-Step Guide

Installing an electric gate can greatly enhance the security and convenience of your property. However, there may be situations where you'll need to cut the chain of the gate to make adjustments or repairs. Cutting a chain for an electric gate may seem like a daunting task, especially if you're not experienced in handling power tools or working with metal.

How Do You Maintain a Gate Chain?

Maintaining a gate chain is important for the smooth functioning of an electric gate. One of the key aspects of maintenance is lubricating your chain. Slide gates, which are commonly used for electric gates, operate on a chain mechanism. These chains should be lubricated annually to ensure optimum performance.

To lubricate your chain, you’ll need heavy axle grease. To prevent the job from getting messy, it’s recommended to place a liberal amount of grease on a cloth. Wrap the cloth around the chain and run it along the length of the chain. This will evenly distribute the grease without creating a mess.

By regularly lubricating your chain, you can prevent any potential issues caused by friction and wear. The grease acts as a protective barrier, reducing friction and extending the lifespan of the chain. It also helps to prevent rust and corrosion, which can cause the chain to weaken and break over time.

In addition to lubrication, it’s also important to inspect your gate chain regularly. Look for any signs of wear or damage, such as broken links or excessive rust. If you notice any issues, it’s recommended to replace the chain as soon as possible to maintain the security and functionality of your electric gate.

By taking the time to inspect your chain and address any issues promptly, you can ensure the security and reliability of your electric gate system.

Proper Cleaning and Maintenance of Gate Chains

  • Regularly inspect the gate chains for any signs of damage or wear.
  • Use a soft brush or cloth to remove any dirt or debris from the chains.
  • Apply a lubricant specifically designed for gate chains to ensure smooth operation.
  • Tighten any loose bolts or screws that may be holding the chains in place.
  • Check the tension of the chains and adjust if necessary.
  • Keep the chains clean and free from rust by applying a rust inhibitor.
  • Avoid excessive force or strain on the chains when operating the gate.
  • Periodically check the alignment of the chains to ensure they’re properly positioned.
  • If the chains become damaged or severely worn, replace them with new ones.
  • Regular maintenance and cleaning will help prolong the lifespan of the gate chains.

This will manually release the motor and allow you to open the gate without electricity. Be sure to consult your gate motor’s manual or contact the manufacturer for specific instructions on how to properly use the manual release feature.

This will typically unlock the motor and allow you to manually operate the gate. If the motor has a manual release lever or handle, simply locate it and turn or pull it to disengage the motor. Once the motor is disengaged, you can manually open or close the gate.

If your gate motor doesn’t have a manual release mechanism, there are a few alternative methods you can try. One option is to use a battery backup system, if your gate motor is equipped with one.

Another option is to use a generator to power the gate motor. Simply connect the generator to the motor using the appropriate cables or cords, and then start the generator to power the motor and open the gate.

If none of these options are available to you, you may need to physically cut the chain or lock on your gate to gain access. This can be done using a heavy-duty bolt cutter or an angle grinder. However, it’s important to note that cutting the chain or lock should only be a last resort, as it will likely damage your gate and may require costly repairs.

Opening a gate without electricity can be done through various methods. It’s important to first try locating and using the motors manual release lever, handle, or key.

Adjusting the tension on a gate chain is a relatively simple task that can be done using chain tension bolts. These bolts, equipped with two nuts and an eye in the head, allow for easy attachment of the chain. By mounting the bolt through the chain mounting bracket and tightening the nuts on either side, the tension on the chain can be effortlessly adjusted.

How Do You Tighten a Gate Chain?

When it comes to tightening a gate chain, one effective method is by using chain tension bolts. These bolts are equipped with two nuts and an eye in the head, allowing for easy attachment of the chain. To begin, position the bolt through the chain mounting bracket, ensuring that the eye is on the side facing the gate.

Next, secure the chain tension bolt by placing a nut on each side of the bracket. Make sure to tighten the nuts securely to prevent any movement or slippage of the bolt. This will ensure that the chain remains taut and properly aligned.

Tightening the nuts will increase the tension on the chain, while loosening them will reduce it.

Remember, it’s important to find the right balance when adjusting the tension. You don’t want the chain to be too loose, as this can lead to sagging and potential damage to the gate. On the other hand, overtightening the chain can put unnecessary strain on the gate mechanism.

Regularly checking and adjusting the tension of the gate chain is essential for optimal performance and longevity. So, don’t forget to include this important maintenance task in your routine!

How to Properly Lubricate a Gate Chain

  • Make sure the gate is closed and in a stable position.
  • Clean the chain using a mild detergent and water solution.
  • Rinse the chain thoroughly and dry it with a clean cloth.
  • Apply lubricant to the chain, focusing on the areas with most friction.
  • Use a brush or cloth to ensure the lubricant spreads evenly across the chain.
  • Allow the lubricant to penetrate the chain for a few minutes.
  • Wipe off any excess lubricant with a clean cloth.
  • Check the chain regularly and reapply lubricant as needed.
  • Remember to use a lubricant suitable for outdoor use and specific to chain applications.
  • Following this process will help prolong the life of your gate chain and ensure smooth operation.


By following the step-by-step guide provided, individuals can safely and efficiently cut through the chain, allowing for necessary repairs or adjustments to be made. It’s important to prioritize safety by wearing protective gear and using the appropriate tools for the task. Regular maintenance and inspection of the chain can prevent future issues and prolong the lifespan of the electric gate. With the knowledge gained from this guide, individuals can confidently tackle chain cutting tasks, ensuring the smooth operation of their electric gates for years to come.
