Gates
Can you add an automatic opener to an existing gate?
Quick answer
Yes. In most cases an existing gate can be automated by adding the right operator, power, and safety devices. Feasibility comes down to the gate's weight and condition, the posts and hinges, whether it swings or slides, and whether power is available at the gate. Heavy, sagging, or undersized gates may need reinforcement first.
What determines whether your gate can be automated?
A few things decide it. The first is the gate itself: weight, span, and condition. Operators are sized to a gate's weight and leaf length, so a heavy steel gate needs a stronger operator than a light aluminum one. If the gate sags, drags, or binds when you open it by hand, an opener will only fight that resistance and wear out early. It needs to swing or roll freely first.
The second is the posts and foundation. A swing operator puts real force on the hinge post every cycle, and a slide gate relies on a straight, level track or guide rollers. Posts that are undersized, leaning, or set in shallow footings often need to be reset or reinforced before automation. In DFW's expansive clay soils, posts that were fine for a manual gate can shift with the wet and dry seasons, so we check them.
The third is the gate type. Swing gates are automated with a ram or articulated-arm operator on each leaf. Slide and cantilever gates use a rack-and-pinion slide operator. Each has different space, clearance, and surface requirements at the opening.
The fourth is power. A standard operator needs 120V at the gate. If running a trench and conduit from the house is impractical, a solar-charged operator is a common and reliable alternative in our sunny Texas climate.
What operator and access controls would I get?
The operator is matched to your gate. Swing gates typically use a linear ram or an articulated arm; slide gates use a rack-and-pinion drive. The right model depends on gate weight, leaf length, and how many cycles a day you expect, so a busy commercial drive and a single-family driveway are spec'd differently.
For access, the common options are: a wireless remote (transmitter) for the car, a keypad for a PIN code, a card or fob reader, and a wired or wireless intercom or smartphone/cellular control so you can let in visitors. Many setups also add a vehicle loop or exit sensor in the driveway so the gate opens automatically as you drive out and won't close on a car sitting in the opening.
Most modern operators also support a battery backup so the gate still works during a power outage, which is worth having on a primary entrance.
Is an automatic gate safe? What about UL 325?
An automated gate is a powered machine, and safety is not optional. The governing standard is UL 325, the recognized safety standard for gate operators. Where a direction of travel has a risk of entrapment, it requires at least two independent means of entrapment protection in that direction, and the two means cannot be the same type. (If one direction has no entrapment zone, it may need only one means in that direction, but the other side still needs two.)
In practice that usually means combining the operator's built-in (inherent) obstruction sensing with an external device: a non-contact photo-eye (an infrared beam that stops and reverses the gate if something crosses the path) and/or a contact safety edge that reverses on impact. Modern operators monitor these external sensors, so the operator checks that they are connected and working and will fault out rather than run if one fails.
A proper automation job includes these devices, plus clearly placed warning signs and a manual release so you can open the gate by hand in an emergency or power loss. We will not wire an opener to a gate without the required safety package; it protects children, pets, and vehicles, and it is what the standard calls for.
Can it run on solar, and when does a gate need reinforcement first?
Yes, solar is a strong option in North Texas. A solar-charged operator pairs a panel with a battery so the gate runs without trenching to grid power. Solar-capable kits are rated by gate weight and leaf length, from light-duty units for gates around 300 pounds or up to about 12 feet, to heavy-duty units that handle several hundred up to roughly a thousand pounds. Sizing the panel and battery to your gate's weight and daily cycle count is what keeps it reliable. Our long, sunny days make solar practical here, though heavily shaded entrances and very high-traffic gates are usually better on wired power.
A gate often needs work before it can be automated. Common cases: the hinge post is undersized or set in a shallow footing and would flex under the operator; the gate frame is too light or racked and will sag once it cycles thousands of times; hinges are worn or binding; or a slide gate's track is uneven. We may add a heavier hinge post, gusset or reinforce the frame, replace hinges, or true up the track so the automation has a solid, free-moving gate to work with.
If you have an existing gate, the most useful first step is a site visit. We can tell you on the spot whether it can be automated as-is, what reinforcement it needs, and which operator and controls fit your entrance. Call (214) 603-9142 or email support@cjmmetals.com to set it up.
NoteAny cost figures are general DFW-area estimates that vary with gate size, weight, material, operator type, access controls, and site conditions; CJM provides an exact price only after a site visit. Gate automation typically involves electrical work and may be subject to City of Arlington and Tarrant County permitting and access requirements (including fire-department access rules for gated drives), and standards such as UL 325 are updated over time. Confirm current requirements with the City of Arlington Planning and Permitting before installation, as rules and prices change.
