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.
There are several kinds of car lifts in operation today. Some of which are two post lifts, 4 post lifts, 4 post alignment lifts, inground lifts, mobile column lifts, short rise lifts, mid rise lifts and home garage lifts.
When installing two-post lifts, you will make sure that the ground where you are installing is very stable. Also you should make sure that it is stable so your item you are holding will not fall over.
The average price for high-quality two post lift is around $3,000. You can find some that are decent quality for as low as $1,000, and you can get very high-end lifts for $5,000 or more.
There are both light and heavy duty car lifts that work for small and large vehicles. Car lifts can hold up to 6,000 pounds, and a four post lift will hold more weight than a two post lift.
A four post auto lift allows you to stack two cars. Some people feel that two post auto lifts are not good for vehicles as they let the front suspension dangle. However, a four post auto lift is also not good for working on cars as it doesn't allow you to work on things like the brakes.
For the construction of a post lift, the material used for construction really depends on what these lifts will be used for. Instead of lumber, you might possibly want to consider steel for additional durability.
Most two post lifts can handle any normal vehicle. The usual capacity for a commercial grade lift is either 10000 lbs or 12000 lbs. This is ample for any normal vehicle like a car or pickup. A box truck like you see delivery men drive usually weighs under 9000 lbs, so that's pushing it with most two post lifts.
The two lifts in Olympic Weightlifting are the Snatch and the Clean and Jerk.
