The most common way to move the gate is with a cylinder. As we discussed in the post on the power source, a 1.5” cylinder is enough to move most gates. As for length, 12” to 16” is most common and it depends more on how the geometry of mounting the gates is looking, how far does it need to swing, and how are you going to mount the cylinder. The Surplus Center 9-4410-xx cylinder series works really well

One of the important things with mounting up hydraulic cylinders on gates is that you want to have a strong enough gate for it. You need strong hinges (I like sleeves over a round end of the gate on all gates). You also need a strong frame to the gate. I like to use a gate that has sch 40 pipe for the top rail when I know that the gate will be hydraulic. 14 gauge is too light and the tubes can break.
The next thing is to have mounts that are strong and also allow you to remove the gate relatively easily. This design works good for this series of cylinder. It spreads the load out along the gate, making it less likely to break off, and it also gives you an easy way to pin the cylinders in place. This lets you remove the cylinder to open the gate is your hydraulic system breaks down.
To select the proper gate operator, one needs a clear understanding of the security level, site conditions, vehicle throughput, visual impact and safety standards that a site requires. These are questions to ask yourself when choosing an automated vehicular gate system for your site.
There are several types of gate operators, each serving a specific function, or purpose depending on site characteristics and security needs. There are five basic types of gates/gate operators:
Safety is of utmost concern when operating any type of gate. This ensures that personal injury and vehicle damage are avoided while opening or closing a gate system. UL 325 Standards determine which safety features need to be present in any given gate design and are classified into four usage classes depending on the type of site where the gate operator is being utilized.
The security level of a site also influences the type of gate operator suitable for it. It often comes down to a choice between being a convenience open or a secured/hardened access point. Convenience open would be used primarily on residential sites or light commercial and industrial facilities, where visitors and employees often come and go. A slide or swing gate are most used for sites with this security level.
Sensitive sites such as airports, prisons, data centers, or federal government facilities would require a hardened access point achieved with a more secure gate operator that can protect against hostile vehicle threats. HVM barriers such as wedge barriers, active bollards, and barrier arms are the best choice for these sites.
The speed of opening/closing a gate is crucial to the overall security of a site. Take slide gates for example — they are dependent on the size of the clear opening, who or what is crossing the access point, and what volume of throughput they will likely see throughout the day. A wider clear opening will obviously take longer to open and close, leaving your site exposed during that extended time.
If the security level requires that the gate is cycled for every vehicle, and gaining access quickly is important, you may need to choose a faster operator to accommodate those requirements. HySecurity offers slide gate operators that travel as fast as 3 ft./sec. When making this decision, also make sure to consider the UL 325 maximum speed limit of slide gates for UL Class I and II.
Identifying the size and weight of the needed gate panel can narrow down the type of gate operator that will work for your site. For example, when selecting a HySecurity SlideDriver™ model, you’ll find weight capacities ranging from 1,500 to 20,000 lbs. For swing gates, wind load can also add weight to a gate and affect its overall performance. To mitigate any wind loading issues, consider a gate panel that provides at least 50% open space. HySecurity offers a unique solution to swing gates with a lot of wind loading via the HydraSwing™ operator.
The operation of any gate operator can be affected by a power outage. To ensure continuous gate operation even during a power outage, consider gate operator models that offer UPS battery backup. These backup power systems allow you to continuously operate your gate operator for 24 to 48 hours (typical for most installations) or until normal AC power is restored. HySecurity offers a range of gate operators with UPS battery backups in DC and AC inverter options.
Note: Automated vehicular access gates are not intended for pedestrian access. Pedestrians must be provided a separate access point.
