How Does a Two Post Lift Work?


To operate a two-post lift, hydraulic fluid flows through equalizer cables that synchronize the lift's two columns. This type of lift is popular in Mechanic Superstore with high ceilings and requires communication between the columns. The hydraulic lines run inside a cross member, which acts as a conduit.

Hydraulic fluid flows to both hydraulic cylinders

The hydraulic cylinder is one of the most important components of an auto lift, and it should be maintained properly to ensure that it works at its best. When the hydraulic cylinder is dirty or damaged, it won't perform well, and this means that it will need repair or replacement. In order to avoid interruptions in work, it is essential to perform regular maintenance on the cylinder. Checking the hydraulic cylinder regularly can save you money in the long run and help you avoid costly downtime.

The two hydraulic cylinders in a two post lift are connected by a pipe. The pipe is connected to the pump and a valve controls the flow of fluid. The valve closes when the fluid is pressurized. The hydraulic fluid then flows into the cylinder, forcing the piston to push against it and raises the car.

Aircraft cable equalization system provides most positive results

The aircraft cable equalization system is an effective tool for lifts that feature two posts. This system uses equalizer cables and hydraulic lines. These lines must run through a conduit at the top of the column or under the floor plate. If the weight difference is significant, the lift structure and equalization system can be strained. The lift arms and carriage are also susceptible to damage.

The equalization system is also known as dual-synchro equalization. This system enables both lift carriages to rise simultaneously. It also provides stability and level lifting.

Concrete thickness is important

When purchasing a 2 post car lift, be sure to check the thickness of the concrete. If the lift is less than two inches thick, the lift may not be stable. The concrete thickness must be at least four inches to ensure stability and safety. A two-post lift can lift between 100-500 pounds. It is also important to make sure that the floor is level and not sloped. Before installing the lift, unpack the parts and double check that the pieces are secure.

Depending on the type of two-post car lift that you choose, you should choose a slab with a thickness of at least four inches. The concrete must also be strong enough to withstand up to three thousand pounds of pressure. Check with a building architect to learn more about the proper thickness of the concrete for your car lift. There are two basic types of concrete slabs: traditional slab-on-grade slabs and post-tension cable slabs.

Types of 2-post lifts

The most common type of 2-post lift is the surface-mounted type with two lifting carriages and swing arms that are synchronized. The carriages must travel level and together, and the arms should be positioned so that they do not interfere with each other when the car is being elevated. This synchronization can be achieved through steel cables or a chain, or hydraulic circuits. In the United States, the steel cable type is the most common type of synchronization.

Two-post lifts are typically inexpensive and convenient to use. They can lift any vehicle and give you excellent access to the underbody. These types of lifts are also highly durable. They are usually sold for $2500 or less, so you can get one at a great price without breaking the bank. These lifts are usually ideal for small garages, temporary installations, and smaller establishments.


When it comes to buying a 2 post car lift, there are a few factors that need to be considered. First of all, you need to consider the weight capacity of the lift. You can purchase a 2 post car lift with a capacity of up to 7,000 pounds. This is not a big capacity, but it will work for most cars. However, you need to keep in mind that this type of lift is not suitable for most commercial vehicles, lift trucks, or vans.

You will also need to consider the ceiling clearance. This is very important for safety reasons. If the lift is going to be used for a heavy vehicle, you will need thicker concrete. Lastly, you will need to consider the cost of the installation. Depending on the manufacturer, you can expect to pay anywhere from $500 to $800. These prices are inclusive of labor and utilities such as hydraulic oil.
