How to Choose the Right Alligator Jack for Your Maintenance Needs?

When it comes to maintaining aircraft, having the right equipment is essential for ensuring safety, efficiency, and effectiveness during operations. Among the various tools available to mechanics and technicians, the alligator jack stands out as an often overlooked option for supporting structures as work is carried out. Unlike various popular options for commercial models, the alligator jack is specially designed for use with private aircraft and other smaller airframes. In this blog, we will explore the design and capabilities of such ground support equipment (GSE), as well as touch upon the topic of choosing the right alligator jack for your specific maintenance needs.

Working Of Alligator Jacks

Like other similar forms of GSE, alligator jacks are primarily used for carefully lifting, propping, and supporting aircraft structures during maintenance procedures so that personnel can safely access various areas. Their design is distinct from the more popularly recognized axle jack, which is often used for raising aircraft by their landing gear. Instead, alligator jacks feature a longer, low-profile lifting arm that allows them to reach under an aircraft to lift it by its fuselage or other designated points. This is particularly useful for smaller airframes where traditional axle jacks may not provide the necessary reach or support for work to be carried out.

The operation of an alligator jack is highly tied to its hydraulic system, which provides the level of force needed to lift up and hold heavy structures in place while inspections, repairs, and replacements are carried out. While capable of managing and transferring significant levels of force, the hydraulics in alligator jacks maintain a compact and portable form factor. As a result, they are beneficial for settings or situations where space may be limited, or where a specific model is better handled with a smaller jack. In order to ensure that the jack has optimal pressure levels to support equipment, users can always refer to pressure gauge readings from integrated instruments or compatible measurement tools.

Benifits Of Alligator Jacks

While many smaller models can benefit from the use of alligator jacks, it is important that one takes the time to find the best fit for their needs before making a purchasing decision. For example, the size and weight of the aircraft will determine what capacity you need to look for in jacks, as options will typically vary. The jack's lifting capacity should generally exceed the aircraft's weight to provide enough of a safety margin to guarantee that loads can be handled without straining the hydraulic system. Additionally, it is highly recommended that one verify that the jack's lifting arm will be able to reach all designated points of the aircraft it will be used on, as not all models are designed with the same lifting points.

Another important consideration when choosing between options is the type of maintenance tasks you will be performing. Some alligator jacks are designed for specific procedures like lifting an aircraft for landing gear inspections or tire changes, while others are more versatile and can be used for a wider range of procedures. As such, understanding the scope of your maintenance needs will help you select an alligator jack with appropriate features and capabilities. For example, if you frequently perform tasks that require very accurate levels of lifting and positioning, you may want to choose a jack with advanced hydraulic controls that allow for finer adjustments to be executed.
