Gate opener kits range in price and are sold separately from the gate. The installers will choose the appropriate opener kit for the style and size of your automatic gate.

Hydraulic gate openers are a popular choice for residential and commercial gates due to their high power and reliability. These gate openers are powered by hydraulic fluid and operate using a series of valves, pistons, and cylinders.

Below, we will explore the basics of hydraulic gate openers, how they work, the different types of hydraulic systems, and more.

How Do Hydraulic Gate Openers Work: The Basics

Hydraulic gate openers generate enough power to open virtually any size of gate. However, this isn’t their only use.

Keep reading to learn how hydraulic gate openers work before you invest in an automatic gate:

Principles of Operation of Hydraulic Gate Openers

Hydraulic gate openers operate based on the principles of fluid mechanics. The hydraulic fluid, typically oil, is stored in a reservoir and pumped through a series of valves and cylinders. The valves control the flow of fluid, while the cylinders convert the hydraulic pressure into mechanical force to move the gate. The hydraulic pressure generated by the fluid is much greater than the force that can be generated by a person, making hydraulic gate openers an efficient and reliable option.

Types of Hydraulic Fluids

Hydraulic fluids are used to transfer power in hydraulic systems. They must have good lubricating properties and be able to withstand high pressure and temperature. The most common types of hydraulic fluids used in hydraulic gate openers are mineral, biodegradable, and synthetic oil.

Mineral oil is the most common type of hydraulic fluid used in gate openers. It is affordable and has good lubricating properties. Biodegradable oil is an eco-friendly option but can be more expensive and require more frequent maintenance. Synthetic oil is also costly but offers better performance at high temperatures and under heavy loads.

Different Types of Hydraulic Systems

Hydraulic gate openers consist of several components, including the pump, cylinder, control valve, fluid, and hoses. There are two main types of hydraulic systems: single-acting and double-acting.

  • Single-Acting Hydraulic Systems: These use hydraulic fluid to move the gate in one direction only, usually to open it.
  • Double-Acting Hydraulic Systems: They use hydraulic fluid to move the gate in both directions, to open and close it. Double-acting hydraulic systems are more efficient and can operate larger gates.

What To Consider When Choosing Hydraulic Gate Openers

You should consider the following factors:


  • Gate Size and Weight: Larger and heavier gates require more powerful gate openers.
  • Speed: If you have a busy entrance or want to keep your property secure, choose a faster gate opener.
  • Durability: Choose high-quality models that can withstand pressure and heavy use.
  • Maintenance: Hydraulic gate openers require regular maintenance to operate properly, so it is best to choose a company that can properly maintain them.
