Can my existing gate be automated?

Can Existing Gates Be Automated?

In most cases, yes, automation can be added to existing gates.

If your hinges face each other, installation is usually straightforward. Where hinges are offset or not directly aligned, this does not necessarily prevent automation. Additional brackets or custom metalwork can often be fitted to achieve the correct positioning and geometry.

The most important factor in any retrofit installation is gate geometry and structural suitability. That is why we always begin with a free site survey. This allows us to assess feasibility and advise on the most appropriate solution, whether that is underground motors or rams fixed directly to the gate.

Structural and Installation Considerations

If you already have a pair of gates that you love and would like to automate them, it will usually be possible. However, the strength and construction of the gates must be suitable for the additional forces created by automation.

Gate Strength and Construction

Automation places torque on the gate leaves, so they must be structurally sound.

Wooden gates should have a frame thickness of at least 70mm. This prevents twisting under motor force and ensures smooth, reliable operation.
Metal gates should not be lightweight tubular constructions. The frame needs sufficient rigidity and substance to withstand the force of the motors without flexing.

If reinforcement is required, we will advise you accordingly.

Hinge Position and Mounting

Correct alignment is essential for safe and efficient operation.

Depending on which face of the post or brick pier the gates are currently hung from, they may need to be removed and re-hung to achieve the correct geometry.

Gates mounted directly to brick piers may also need to be re-hung from new structural posts, particularly if the existing piers are hollow or not designed to handle the additional load of automation.

If underground motors are chosen, the gates will always be removed from their existing hinges so the motors can be properly installed beneath the hinge point.

Choosing the Right Automation System

There are two main types of automation used for existing swing gates.

Hydraulic or Electro-Mechanical Rams

In most installations, either hydraulic rams or electro-mechanical motors are mounted on the rear of each gate leaf.

The right system depends on:

The weight and size of the gates
How frequently they will be used
Whether the property is exposed to strong winds

For heavier gates or particularly windy locations, hydraulic rams are generally recommended. They offer greater strength and durability under load. Electro-mechanical systems are often suitable for lighter domestic gates in more sheltered environments.

Underground Motors

In some situations, underground motors can be fitted to existing gates. However, the deciding factor is always geometry.

Very few gates are originally installed in a way that allows underground automation to be added later without modification. The hinge position, ground levels, and surrounding structure all need to allow for precise motor placement beneath the hinge point.

Underground motors:

Involve more extensive installation work
Require excavation and ground preparation
Are more expensive than above-ground systems
Provide a far more discreet finish

They are largely hidden from view, with only a small metal access lid visible at ground level. Following a site assessment, we can confirm whether this option is viable for your gates.

Whichever system is most suitable, when you choose to work with AutoGate Services you will receive high-quality, reliable automation backed by a 2-year guarantee. If you are not completely satisfied with any aspect of our work, we will put it right.

The Next Step

Every existing gate installation is different. A free site survey allows us to assess your gates, discuss your priorities, and recommend the most practical, reliable and cost-effective automation solution for your property.
