Workplace organization

If care of the car has to remain simply a hobby, to it should correspond and external conditions.

Always to put the car on a support!

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

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

What suits 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 should 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 when lifting one party of the car the racks 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 should have the sufficient area of a support!

The platform is, certainly, the best option of a support as the jack here 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 necessary to get only a strong design. The similar jack approaches and at works with the car which body in lifting places already slightly decayed. In that case it is possible to establish a similar jack closer to the body middle.

Hydraulic plunzherny jack: before purchase you should check lifting height. Too short jack will not lift a car wheel rather highly. In general it will be correctly impossible to establish too high jack on soil.

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

(2) it is possible to establish an onboard automobile jack only under the marking beaten out on a body (1) in a groove of the bottom of the car. 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 better will approach. 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!
