Getting to Know Your Hydraulic System: Hydraulic Cylinders

How Hydraulic Cylinders Help your Hydraulic System Work

Semi-truck hydraulic systems rely on hydraulic cylinders to perform heavy-duty tasks with efficiency. Though often behind the scenes, the hydraulic cylinders in your commercial vehicle's hydraulic system play a crucial role in raising and lowering trailers, as well as steering and braking. To help you learn as much as possible about the cylinders in your truck's hydraulic system, we will delve into the functionality, components, and necessary role they play in keeping you on task. Read on to learn more!

What is a Semi-Truck Hydraulic Cylinder?

Semi-truck hydraulic cylinders are mechanical devices that use the force of pressurized hydraulic fluid to convert linear motion into the power needed to move heavy loads. Composed of a cylindrical barrel, a piston, and a piston rod, these cylinders are responsible for generating the incredible force needed to perform various tasks. Whether it's raising and lowering the trailer bed, extending the boom arm on a crane truck, or steering the vehicle, hydraulic cylinders are a versatile way to make sure your truck can easily move heavy loads.

How Does a Hydraulic Cylinder Work?

The way semi-truck hydraulic cylinders work is based on Pascal's law, which states that when pressure is applied to a fluid in a confined space, it is transmitted equally in all directions. Inside the cylinder, hydraulic fluid is pumped under pressure, causing the piston and piston rod to move. The barrel houses the fluid and guides the piston's motion, while the piston separates the fluid chamber and converts hydraulic pressure into linear force. The piston rod extends from the piston and transmits the generated force to the equipment, allowing the attachment to perform it's intended task.

What are Hydraulic Cylinders Used for?

Semi-truck hydraulic cylinders are used for a wide range of applications. For instance, in trailers, hydraulic cylinders control the movement of the trailer bed, enabling smooth raising and lowering for cargo loading and unloading. In crane trucks, hydraulic cylinders extend the boom arm to reach distant heights, so that it can easily lift heavy objects. Hydraulic cylinders also play a vital role in steering systems, enabling drivers to easily and safely maneuver large semi-trucks. Braking systems also utilize hydraulic cylinders to apply pressure to the brake pads, ensuring effective and reliable stopping power.

How to Maintain your Hydraulic Cylinders

To make sure your cylinders provide optimal performance and longevity, they require regular maintenance. Proper lubrication and inspection of seals and connections are essential in making sure they are working properly. Additionally, monitoring fluid levels and addressing leaks promptly is a crucial step in preventing system failures. Routine maintenance not only ensures the efficient operation of hydraulic cylinders, it also minimizes the risk of costly breakdowns and downtime. By keeping these vital components in peak condition, you can maximize productivity and maintain safe and reliable operations.
