How Deep Should Concrete Be For 2-Post Lift?


There are a few things you need to understanding Mechanic Superstore when installing a MaxJax 2-post lift on concrete. First of all, the depth of your concrete slab is important. It must be at least 4 inches thick. Also, you need to know where to install your tension cables.

Installation of MaxJax 2-post lift on concrete

The MaxJax 2-post lift is designed for garages with limited space and offers an innovative two-post design. It is more versatile than traditional garage lifting systems. Before you install the MaxJax, check to see if the concrete is in good condition and free from cracks.

Install the MaxJax lift on concrete by following the installation instructions provided with the lift. Then, use the concrete anchors to secure the lift to the concrete. The anchor bolts must be tightened to 90 lb.-ft., and the lift should be installed at least six inches from walls or significant floor cracks.

Requirements for concrete slab

When installing a 2-post lift, it is important to ensure that the concrete slab is strong enough to support the weight of the lift. To do so, the slab should be four inches thick and be able to withstand three thousand pounds of pressure. A building architect will be able to advise you on the proper thickness of the concrete. However, the thickness of the concrete slab will also depend on the type of lift being installed. A 4" concrete slab is usually sufficient for a two-post lift, but may be inadequate for a post lift with a heavier lifting capacity.

Once the slab is ready, the installation of the lift can begin. It is important to ensure that the slab is level and preferably, has no slope. Concrete slabs that are not level are unsuitable for lifting.

Thickness of concrete slab

If you're installing a 2-post lift in your driveway, you'll need to prepare the area for the lift. The first step is to dig a hole at least two feet by two feet and about 10 to 12 inches deep. Once the hole is prepared, you'll pour concrete to secure the lift. You'll also need to ensure that the area is level and that the ground is reinforced.

Concrete slabs should have a thickness of at least four inches. They should also be able to handle 3000 psi. The exact thickness you need depends on the brand and type of lift. Generally, a four-inch slab will be sufficient for a two-post lift, but a post lift with a higher capacity will require a thicker slab.

Location of tension cables

Post-tension cable slabs are often used in residential construction. These slabs have been in use since the 1950s and provide rigidity to concrete that is poured above voids in the soil. The location of tension cables is often indicated on the building plan. Ground-penetrating radar can also be used to check the integrity of post-tension cable slabs.

When installing a 2-post lift, the power unit column is typically installed on the passenger side of the lift. This makes it easy for the operator to position the vehicle from the driver side and position the arms. The operator then stands and raises the lift using the power unit. It is important to ensure that the cables are properly installed before tightening the bleeder screws.

Adding gravel under slab

Adding gravel under your slab will not only increase the durability of your car lift, but it will also help with the leveling. This will prevent the slab from settling on the ground and causing cracks. Adding gravel will reduce the amount of concrete that needs to be poured. Aside from this, it will also reduce the amount of moisture that enters the slab.

In addition, you will want to add a vapor barrier. This will prevent moisture from wicking up through the concrete slab, which can lead to unsightly wet spots or efflorescence, both of which are safety hazards.

Recommendations for laying concrete for 2-post lift

When laying concrete for your 2-post lift, you will have to take certain precautions to avoid damaging the lift. You should first make sure that the concrete is at least four inches thick and will be set at a depth of approximately six inches below the top of the lift. Next, you need to dig a hole that is about two feet across and two feet deep for each of the columns. Finally, you need to apply concrete to the hole to secure it.

When laying concrete for your lift, you must ensure that it is of sufficient thickness and is free of cracks and expansion seams. If your slab is not sufficiently thick, you should modify it to suit your needs. If you plan to place your lift on an elevated floor, make sure that you get written authorization from your building architect. Also, you should place the anchors at least six inches from control joints, expansion seams, and other irregularities in the concrete. Also, you should never use hand-mixed concrete.
