3,000 PSI reinforced concrete is required for a 4 post lift
To install a Mechanic Superstore’s free online 4 post car lifts, you will need to pour a minimum of 3,000 PSI of reinforced concrete. This amount is considerably higher than the minimum thickness required for 2×4 lumber. However, you must note that this thickness should not be less than four inches, since it is not the standard concrete thickness for a 4 post lift.
You should start by measuring the concrete area and inspecting the slab. It should be at least four inches thick, with a slope of no more than three degrees. To make sure the concrete slab is properly supported, you should have a building architect check the PSI of the concrete slab. For a 2-post lift, a 4" concrete slab should be adequate, but if you are installing a four-post lift, the required PSI should be three to five times the weight of the car lift.
Adding reinforcement to an old or damaged slab
Before you begin adding reinforcement to an old or damaged slab, make sure the beam has adequate structural support. This can be achieved by installing shoring posts. These posts support the beam while you work. Also, check the internal seal of the hydraulic jack, which can cause the jack to slip and drop the load. Before you begin, carefully remove the old concrete floor and measure the dimensions of the post. If the slab is more than two-and-a-half inches thick, you will need a larger, diamond-edged circular saw. Use a plastic sheeting to protect your floor from dust while you work.
For new slabs, the thickness should be 6 inches. This thickness is required by building specifications. It's important to obtain certified strength documentation from the concrete mixture supplier. If you're installing a lift in a basement, you must first obtain written permission from the building architect. Adding reinforcement to an old or damaged slab for a 4 post lift may be a simple DIY project, but it should be done with care.
Pre-existing floor requirements
If you are going to install a 4 post lift in your home, you need to consider a few factors. Firstly, you must make sure that you have a floor suitable for the lift. If the floor is not suitable for the lift, you need to ensure that the room is large enough for the lift to fit.
The floor must be strong enough to support the columns. Most manufacturers recommend a six to twelve inch concrete depth and a PSI of at least three thousand. This may be difficult to achieve with the existing floor but is still an essential consideration.
Adding gravel under a 4 post lift
Installing a 4-post lift is a good way to extend the use of your garage. You will need to prepare your garage floor for the lift to work properly. You will need to add gravel under the lift to help level the surface and prevent any settling within the concrete. Make sure to add the right amount of gravel to the ground. If you skip the gravel, you risk damaging the lift.
A 4 post car lift has several benefits. It is portable. If you need to move it from one place to another, you can install a jack tray attachment. A 4 post lift also gives you more storage options, such as a storage bin for motorcycles, riding lawn mowers, or snowblowers.
Limiting factors
When selecting a four post lift, you should consider a few important factors before making a purchase. First, make sure that the lift fits inside your garage or deck. This is important because it will determine how long the car can be lifted and how much room you have for a buffer. Also, check how wide the car will be when placed on the lift. If you need extra room, you can purchase a four-post lift with a longer wheelbase.
Another important consideration is weight limit. Lifts carry massive weight, which can pose a safety hazard if not used properly. Fortunately, modern lifts have many safety features. These systems can prevent cars from falling from a height, but in rare cases they can still fail. When purchasing a four-post car lift, remember that different models come with different weight limits. Make sure you check both the weight and height limits before making a purchase.
