The workplace organisation

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 a correct support for your raised car!

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

What suits as a support?

Hollow blocks have 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 that loading was distributed in regular intervals on a surface of all block. The block should stand necessarily apertures upwards (vertically) on flat and capable to sustain surface loading (concrete or asphalt).

Podstavnye racks is an ideal addition to a garage jack. However there is a danger that at lifting of one party of the car the racks established on the other hand, can overturn because of wrong installation of a tripod. Is better 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, best variant of a support as the jack here is not necessary. Besides, the car costs reliably enough.

Jacks

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 jack support it was not pressed into a ground.

Jack параллелограмного 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 has slightly decayed. In that case it is possible to establish a similar jack more close to the body middle.

Hydraulic плунжерный a jack: before purchase you should check up lifting height. Too short jack will not lift a car wheel highly enough. Too high jack in general cannot be established correctly on a ground.

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



The onboard automobile jack (2) can be established only under the marks 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 marks (1) such garage jack is established. However in this case the longeron under a body is 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!
