Understanding Two Post Lifts

Answer 1

In the world of automotive repair, two post lifts are essential. Without them, the processing of lifting up a vehicle, in order to work on it from below, would be a lot more difficult. The kind of two post lift that is needed will depend on the types of vehicles that one works on regularly; heavier vehicles, like large trucks, will require stronger lifts. Before investing in a two post lift, however, it is smart to know the basic differences between the two primary types: symmetrical two post lifts and asymmetrical two posts lifts. The following information can help.

Symmetrical Two Post Lifts

For a long time, symmetrical two post lifts were the only available options. Under this configuration, a vehicle is centered on the lift in a balanced way. The same amount of the car rests in front of the posts as it does behind the posts. The practical benefits of this design are apparent: The risk of a vehicle tipping off are quite low. Still, drawbacks exist. The most glaring one is the fact that entering and exiting a car on such a lift is not easy, since the door is somewhat blocked by the posts. What's worse is that car doors often become dented and dinged on symmetrical two post lifts.

Asymmetrical Two Post Lifts

Asymmetrical two post lifts were designed in response to the deficiencies of symmetrical two post lifts. Under this design, a vehicle is positioned further back on the lift. About two-thirds of the car, then, is positioned behind the posts. As a result, doors can be opened with ease - and without the threat of becoming dented and damaged. Like their symmetrical counterparts, though, these types of lifts have their drawbacks. The biggest one is the fact that some vehicles - most notably rear engine cars and trucks with extra long crew cabs - don't balance well on them. The danger of inadvertent falls, then, increases.

Choosing the Right Two Post Lift

The main decision that needs to be made when selecting a two post lift lies between symmetrical and asymmetrical models. A mechanic needs to weigh the pluses and minuses of both designs and settle on the configuration that is right for him. If frequent entering and exiting of a car is necessary, an asymmetrical lift may be the right option. If work is regularly done on trucks with long beds and extra long crew cabs, though, a symmetrical design may be the best choice.
