When it comes to lifting and supporting heavy objects, gas struts are the go-to solution. These mechanical devices provide a means of support, assist in lifting objects, and provide a controlled release. This article delves into everything one needs to know about gas struts, including their functionality, applications, and installation methods.

What Are Gas Struts?

Gas struts are mechanical devices that use compressed gas and oil to support and control the motion of various applications such as vehicle boots, doors, cabinets, and hatches. They work on the principle of compressing nitrogen gas inside a cylinder which then assists in supporting or lifting the load. Gas struts are particularly useful for lifting heavy objects, as they provide a controlled and secure release once the load has been lifted.

How Do Gas Struts Work?

Gas struts work on a fairly simple principle; the compressed gas inside the cylinder creates pressure that pushes a piston, lifting and supporting the load. The amount of pressure depends on the amount of gas inside the cylinder. Once the load has been lifted, gas struts release the pressure, bringing the load down in a controlled manner. The amount of force needed for lifting and releasing the strut depends on the weight and size of the load.

Where Are Gas Struts Used?

Gas struts are widely used in various applications because of their flexibility and functionality. Some of the popular areas of use include the automotive industry, industrial and manufacturing settings, aerospace, and marine. Automotive applications include the opening and closing of car boots, bonnets, and hoods. They are also used in industrial settings, such as heavy equipment and machinery, where opening and closing heavy doors and cabinets can present a challenge.

How to Install Gas Struts?

Installing gas struts requires a few simple steps. The first step is to determine the weight and size of the load you want to lift. This information will help you determine the force needed to lift and support the strut. The next step is to measure the mounting points, purchase the appropriate gas struts and brackets, and then mount the brackets to the load and the supporting structure. Finally, attach the gas strut to the brackets and test to ensure that the load is lifting and releasing as needed.

Maintaining Gas Struts

Like any other mechanical device, gas struts need regular maintenance to remain functional. The gas strut’s piston and barrel should be kept clean and free of debris and dust to prevent rust and friction, which can cause damage over time. If a gas strut becomes damaged, it should be replaced immediately, as it can pose a safety risk.
