Jacks are essential tools in every automotive enthusiast’s toolbox. From every commercial automotive shop to every personal garage toolkit, a hydraulic floor jack is perhaps the most popular device.
Jacks are used for lifting heavy vehicles off the ground for the dual purpose of servicing and maintenance. The more powerful the jack the more stability it demonstrates in the suspension and lowering of the said heavy weight.
Available in many shapes and sizes, depending on the purpose of its use, these jacks can be categorized as one of the following- floor jacks, scissor jacks, pit jacks, bottle jacks, rolling jacks, bridge jacks, etc.
How Do Hydraulic Floor Jacks Differ from Regular Jacks?
Hydraulic floor jacks, as the name implies, work based on hydraulic systems that can be explained by Pascal’s principle or law of fluid mechanics.
Basically, it means that when there’s a change in pressure at any point in a confined, incompressible fluid, that change is transmitted throughout the entire fluid without any loss.
Simply put, the law states that if you push or squeeze one part of a fluid, the effect propagates to all other parts of the fluid.
So, unlike, say, mechanical jacks, hydraulic floor jacks work because of the transfer of motion through a fluid medium within the cogs of their machine.
How Do Hydraulic Floor Jacks Work?
To understand simply the workings of a hydraulic floor jack, let us consider the example of a hydraulic system of operation, consisting of the following broad components:
- hydraulic oil,
- reservoir or buffer or oil tank,
- main cylinder or ram,
- release valve,
- control valve,
- check valve,
- lifting arm or pad,
- hydraulic pump with piston or plunger, and
- pump lever or handle.
The reservoir or buffer or oil tank is the physical compartment of the hydraulic jack that holds the hydraulic liquid or pump oil together when it is not in use. The control valve stays in a closed position when the hydraulic jack is not in use to prevent the accidental flow of oil.
The piston is responsible for lifting the heavy load or weight. It is usually mechanically activated by shifting the positions of the handle or pump lever attached to it. This movement builds up pressure in the hydraulic fluid contained inside the reservoir or buffer tank of the hydraulic jacks.
When the handle or lever of the hydraulic pump with piston or plunger is mechanically lowered or raised, it activates force and builds up pressure in the adjoining compartment, i.e., the reservoir or buffer tank containing the hydraulic fluid or pump’s oil, inside hydraulic jacks.
The pressure created allows the fluid to move through a check valve into the ram or main cylinder, which then pops out of the main body of the hydraulic jack creating the force required to lift the load.
This applied pressure is what transfers the oil from the pump through the check valve and into the main cylinder or the ram, which extends out of the hydraulic jack body. Finally, the release valve relieves the built pressure for easy retraction and lowering of the ram with the load on it, creating the required lifting force and lifting the load.
Top 3 Essential Hydraulic Floor Jack Accessories
- Jack Stand– Jack stands are essential floor jack accessories that provide support for the tools during use. They work as stabilizers in the lifting, suspension and lowering process. By ensuring that the jack stays in place while lifting heavy weights off the ground, they provide safety and security to the vehicle being lifted and the personnel involved in lifting it, successfully.
- Rubber Pad– Better known as lifting pads, foam or rubber pads provide a system of cushioning to the vehicle being lifted by the jack. This ensures that there are no scratches, dents or other types of harm inflicted by the jack on the vehicle. If not for these cushioning rubber pads, vehicle injuries can turn out to be very expensive for the owner.
- Car Jack Adapter– Last but not least, car jack adapters are our final feature on the list of the top 3 essential hydraulic floor jack accessories. These support tools come in a variety of sizes and can be used on all types of hydraulic floor jacks. They are used by attaching to jack bodies and enhancing their extension to reach the desired lengths.
Stan Design Inc. Hydraulic Floor Jack Features
With over two decades of experience in the automotive industry, Stan Design Inc. brings to you hydraulic floor jacks with cutting-edge technology. At the heart of our innovative features lies a beautiful marriage of design and manufacturing that embodies the ideal of convenience and safety at affordable prices.
Hence, we had dived deep into analyzing the most pressing issues within the industry and found out that garage owners across the nation were wasting countless hours every day lifting heavy-duty vehicles with slow and cumbersome floor jacks that require multiple stands to support the truck.
So, we came up with Scorpion floor jacks with both hydraulic and air bag functionality. Because of the powerful hydraulics and the push of a button on a remote-controlled system, our hydraulic floor jacks do not require additional jack stands for support. We have also successfully eliminated the need for car jack adapters.
Our in-built automatic three-stage locking mechanism allows us to maintain the car as well as personnel’s safety during the lifting, suspending, and lowering operation.
