The 4 post car lift gets its name from the four supporting posts. However the feature that makes it unique is the bridge-jacks. Automotive can easily drive on and off of these supports made of metal. Till the time the wheels of the car are up on these supports, the weight is balanced. The arm adjustment which is needed in case of two post hoists is not required in the case of a 4 post car lift. Thus it takes very less time to get the vehicle up on and off the rack. However in this kind of setup, the access to some various important components of the automobile is restricted such as the suspension and brake.
This system provides adequate space in between the bridge jacks for accessing most of the underbody parts of the car including the exhaust, fuel system and the drivetrain. Many a times these are used in place of pits for lube service.
The heavy duty truck hoist has a cat-walk for accessing the engine while the truck is up in the air. The alignment racks are a bit different in this kind. Rollers and measuring equipment is added to the racks. However these can still be used as a four post car lift whenever needed. The jack tracks between the hoist's bridges can hold the trays, jacks and other accessories which makes the work of transmission easier. The gearbox can be rolled and moved up, down, forward and backwards. This makes it really easy to line up with the bolt holes and mounts.
New light models of 4 post automotive lifts have come up in the market which aims at those consumers who wish to make the most out of their garage space. In this one car can be held on the rack, leaving out enough space underneath for another car. In the high-lift type, the space is enough to park a conversion van or an RV.
Although it takes up more space than two post type, yet the benefits are more and are very suitable in certain situations. It is important that you buy these from a reputed manufacturer or seller.
