Organization of a workplace

If care of the car has to remain simply a hobby, to it there have to correspond also external conditions.

Always to put the car on a support!

Jacks are good only to raise the car. They cannot serve as a reliable support during the works under the car. Even in the biggest haste do not forget about the correct support for your raised car!

For fixing of the car during rise by a jack it is necessary to prop up wheels. For this purpose it is necessary to enclose under them the stones, wooden or iron "boots" or other subjects holding the car from rolling.

What is good as a support?

Hollow blocks proved as a possible inexpensive support. However they should not be damp or with cracks, differently under loading they can develop (to collapse). Between the block and a body it is necessary to lay a board in order that loading was distributed evenly on a surface of all block. The block has to stand surely openings up (vertically) on flat and capable to sustain surface loading (concrete or asphalt).

False racks is an ideal addition to a garage jack. However there is a danger that at growth of one party of the car of a rack, established on the other hand, can overturn because of the wrong installation of a tripod. It is best of all to establish racks so that one foot showed aside, and two – in the car. Racks have to have the sufficient area of a support!

The platform is, certainly, the best option of a support as here the jack is not necessary. Besides, the car costs rather reliably.


There are many designs of jacks – the for each purse and each purpose. Here some of them are listed:

Automobile onboard jack: always it is necessary to enclose a small plate that a support of a jack it was not pressed into soil.

Jack of parallelogramny type: it is worth getting only a strong design. The similar jack approaches and during the works with the car which body in rise places already slightly decayed. In that case it is possible to establish a similar jack closer to the middle of a body.

Hydraulic plunger jack: before purchase you have to check rise height. Too short jack will not lift a car wheel rather highly. Too high jack in general cannot be established correctly on soil.

Garage jack: for those who prefers to work independently, the short small garage jack which is convenient for storing well will approach.

The onboard automobile jack (2) can be established only under the marking which is beaten out on a body (1) in a car bottom groove. It needs to be considered both in front and behind.

Also under marking (1) such garage jack is established. However in this case the longeron under a body will approach better. Not to damage it, it is recommended to enclose a plate (2) between a jack and a body.

 Never forget to substitute a support if you work under the car!
