Jack podkatnye - choose our reliable rear for heavy duty applications

operating principle of Jacks

Rams usually called mechanisms (portable, mobile or stationary), with the help of which the hoisting to a certain height.The size of your device and these mechanisms are different:. Screw, the rack, pneumatic, wedge, hydraulic, etc. Here it is the latter, a hydraulic car jack version equipped with steel wheels, reminiscent of a small narrow carriage, called Jacks.

The most common hydraulic jacks used in automotive service organizations.Like stationary, Jacks combined in one design special hydraulic cylinder and piston pump with manual lever drive.

Such designs have the following advantages: full autonomy, high efficiency and safety carried out repairs.Usually the choice Jacks is associated with a whole set of reasons and factors.Since whether or not it will be used in conditions such as tire shop or a private garage.

Of course, such a simple, efficient and highly reliable lifting device is indispensable in case of need for small repairs, replacement tires, wheels, lift and smooth descent of the car in the garage conditions.For small tire or a full car service rolling jack is useful to replace the wheel operations or repairs.

It allows you to carry out repairs on site or adjacent parking lot, which saves time, space and manpower.In addition, the design options are almost all Jacks allow packaging removable stands and grips that extend their capabilities.Many models are available thrust pins, increasing operational safety in the raised position.

parameters, which should be selected jack

Among interest primarily parameters considered load Jacks.It could be from two tons.There podkatnye jack 3t, 5t and higher, and there is also 750 kilograms, for motorcycles and ATVs.

payload of two tons may be sufficient for personal garage with a small passenger car.But the owner of a solid technology, inveterate "dzhippery" load should be considered from three tons.And that if the car does not exceed the specified weight.

Besides duty, Jacks (as well as other mechanisms for this purpose) have a certain range cargo lift heights.Usually from the minimum values ​​(80-130 mm) to the maximum (350-800 mm).Of course, choosing a version of the model, you need to take into account the minimum height, taking into account the need to accommodate the heel of the jack under the seat all the way into the back of the car.

already mentioned stop pin , inserted into a special slot, significantly increases the safety of operation in the raised position with the load.Although safety is strictly prohibited without the stop operation in a rack or holder, often this requirement is not met.

The presence of the pin guarantees to avoid a sudden failure due to the folding ram hydraulic ram mechanism.

lever is longer or shorter, may have special forms the handle, on which work becomes more convenient.An important is the length of the handle of the jack lever.It is obvious that the jack podkatnye 3.5 tons easier to use with a long-handled, because such a large lever and lift the heavy car easier.

At the same time, cars are practical for a short handle.However, manufacturers have provided an option of modular lever handle, having the ability to control the length, in accordance with the requirements of the situation.Among the proposed

jacks weight models can be quite different.The lightest weigh about five to six kilograms, the next category is already about twelve.But load and own weight jacks are not directly related.

So, the two-ton cargo can lift mechanisms with a weight of ten kilograms and fifty kilograms.The choice also can have a big impact manufacturer - domestic or foreign.A separate line jacks are from Chinese manufacturers.

Tips Operating Jacks

Decide how to select the rolling jack, it is worth considering some of the features of its operation.Jacks budget series often have plastic packaging in the form of case studies, they are not heavy, and satisfy the needs of the majority of car owners.

peculiarity of operation may be the need for periodic pumping of the hydraulic system.This will help prevent or reduce the risk of arbitrary lowering of the jack under the load.As a rule, use instructions describe the sequence of actions when pumping.

Besides being able to bleed and, as a result, lowering, during the winter hydraulic fluid could freeze all that is necessary to take into account, among other factors.And once again I need to remind you that next to the briefcase in the trunk should be based on simple support tripod as a guarantee of safety repairs.

Using Jacks, its packaging should be supplemented by a couple of rubber O-rings to protect the car body coating.Since Jacks are equipped with steel wheels, in certain positions, and on the slopes of the jack may slide, especially under load.Therefore, we must take measures to avoid this danger: skid stops, stops, etc.
