The majority of automobile owners are fully aware of the need for rigorous vehicle maintenance and repair. After all, purchasing a vehicle represents a big investment that needs to be safeguarded at all costs. The typical driver must perform a lot of routine maintenance, from changing the oil in a car to replacing the brake pads.
You need to have a specific set of tools available if you want to safely handle maintenance issues of this sort on your own. A hydraulic floor jack is one of this equipment’s most crucial components.
A floor jack is a hydraulic lift that is manually operated. It is one of a few distinct types of jacks that are available and are more frequently found in mechanics’ garages than in automobile trunks.
They are almost entirely used to lift vehicles off the road for maintenance and repairs.
The low profile of floor jacks makes it simple for them to roll beneath moving vehicles.
Working of Floor Jack:
Floor jacks rest on two fixed wheels and two swiveling casters, unlike the other types of jacks. They are incredibly portable because of this.
The jack is rolled by the operator till the saddle is beneath the lift point. The hydraulic cylinder elevates the lift arm by pumping upward and downward on the handle till the saddle comes into contact with the car.
A hydraulic cylinder is horizontally positioned. It can be compared to a bottle jack that is lying on the side.
Floor Jack selection:
When choosing a floor jack, make sure this will fit below your car and has a weight rating appropriate for your automobile (often, 2 or 3-ton capability jacks will do).
A solid, long-lasting floor jack is essential since it will assist hold the automobile elevated above you as you work, so it is crucial to choose one that suits your demands. See our article on the finest floor jacks here.
Although many cars are coming with such a scissor jack, we advise using a floor jack wherever possible for increased safety.
Various Kinds of Floor Jacks:
A wide range of jacks is categorized as “floor” jacks in some references. They then divide them into subcategories with names like “bottle jack,” “scissor jack,” and so forth.
For our purposes, a floor jack is a particular kind of jack, specifically the wheel-mounted, low-slung sort made specifically for lifting vehicles, as shown in the illustration at the start of this page.
There are several variants of the fundamental design of floor jacks.
Prioritize safety when changing a tire on the road before flat tire removal. Use the hand brake after correctly parking the automobile, ideally on a level surface with all the tires pointed in the same direction. Block the wheels for increased safety. When it’s time to lift the car, slip the floor jack or also scissor jack under there, making that the jack saddle lies directly below the suggested lift point. The rail of the frame, pinch weld, suspensions arm, as well as rear axle is the suggested lift sites.
Use of Floor Jack:
Some of them sometimes referred to as “Low Profile,” are particularly low to the ground. Some are built completely of aluminum, making them lightweight and ideal for simple storage and movement.
Use Jack stands in addition to the garage floor jack when working on the vehicle for extended periods of time, such as when performing a change of oil or other repairs and also maintenance, to ensure the car is stable and fully supported. Otherwise, you run the danger of getting held down by the vehicle. To ensure the stability of the jack and the car, it is best to do repairs on a flat solid slab.
The sheet metal components in the car’s underbody may become damaged if the jack saddle is not positioned correctly. Shut the hydraulic valve by turning the floor jack handles clockwise after the jack saddle is placed in the proper position. To lift the car, press the handle to start the piston, which will then use hydraulic fluid. Lift the car gently.
Lower the automobile gradually after fixing the flat tire or finishing your repairs. The hydraulic valve must first be released by turning the handle in the opposite direction of clockwise rotation. Never forget that floor jacks frequently have an oily or dusty surface. While working on it, your hands could slosh.
It is a good idea to screw in the tyre before lowering the car when changing tiers. The newly inflated tyre can help moderate the fall, so even when the floor jack failed or the car drops quickly as a result of poor handling, the automobile won’t slam down violently. When you’re finished, place a floor jack and the jack stands away.
How much floor jack can elevate?
Approximately 12 to 14 inches might be lifted by a conventional car jack. For an SUV or truck, this seems to be rarely high enough because they frequently need to be raised to heights of over 16 inches. But bear in mind that every car is unique.
What distinguishes a floor jack from a trolley jack?
Floor jacks often have a lightweight build, making them portable with ease. Trolley jack structures are often made of steel and have a release spring which enables the user to release the jacks quickly and effectively.
Is it dangerous to use a hydraulic jack?
The three most frequent risks involved with jack use are load slipping off from the jack, jack placement on rough surfaces, and collapsing from trying to rise more than the jack can support. The OSHA regulations are created to reduce these risks.
A 2-ton floor jack is it sufficient?
A two-ton jack should be adequate for elevating a corner on the majority of sedans and small automobiles. In order to provide you with the necessary margin of safety, a pickup truck and SUV may need to be rated at double that weight (four tones).
