Review of the best models
And although the market is represented by a huge selection of jacks with a lifting capacity of 2 tons, not all of them have proven themselves well among users. Therefore, when purchasing such a lift model, experts recommend taking into account the rating of the best devices that have received positive reviews.
For example, the following jacks can be considered reliable.
SPARTA 510084. This version is equipped with a special safety valve and perfectly copes with lifting loads weighing up to 2 tons. Its minimum lifting height does not exceed 14 cm, and the maximum is 28.5 cm. The device can be successfully used not only at car repair stations, but also in construction work.
Selection Tips
The choice of any tool depends on its purpose and conditions of use. There are a number of aspects to consider when choosing a 3 tonne jack.
The first aspect to look for when buying is the lift height. The value determines the ability to lift the load to the required height
This parameter most often varies from 30 to 50 cm. As a rule, this height is sufficient when replacing a wheel or performing minor repairs.
Pickup height is an important factor when choosing. Many motorists consider this parameter to be not so important. However, it is not. The choice of the required pick-up height is determined by the vehicle's ground clearance. Almost all types of jacks with a lifting height of more than 15 cm are suitable for SUVs and trucks. The ground clearance of a passenger car does not always exceed 15 cm, therefore, in this case, it is recommended to choose screw, rack or roll jacks.
In addition, when buying, you should pay attention to the presence of thrust pins and grips. These elements can provide a secure footing and safe operation on the road.
The dimensions and weight of the jack determine the possibility of convenient transportation and storage. Compact models weigh no more than 5 kg.
Not a single motorist can do without a jack. Lifting devices with a lifting capacity of 3 tons are considered the second most popular after 2 tons jacks. Most models are compact and easy to store in your garage or car. The choice of tool is based on many criteria. But the most important ones are listed above.
You can get acquainted with the test drive of the rolling jack in the following video.
Main characteristics
The jack with a lifting capacity of 2 tons is a device that is designed for lifting heavy loads. This device differs from cranes and other hoists in that its lifting force acts from the bottom up. The jack is activated by pressing a special lever or by rotating the handle, after which the platform with the load rises up. It is worth noting that jacks with such a lifting capacity are very reliable in operation. In addition to the above advantages, you can add a few more to them:
- stability and rigidity of the structure;
- high efficiency;
- smooth lifting and lowering of the load.
As for the shortcomings, there are very few of them (besides, they do not apply to all models of jacks):
- some models, due to the large initial pick-up height, do not allow lifting cars with a low seating position;
- hydraulic models require a level and solid surface.
Model rating
Jacks with a lifting capacity of 2 tons give a good result. For example, "Bison Master 43040-2". This screw device has a lifting height of 0.12 m. The loads will be lifted to a height of 0.395 m. The empty weight of the lift is 3.5 kg; it is quite sufficient for working with passenger cars.
Carrying capacity of 3 tons has a jack "Avtodelo 43330".The main mechanism is a special rail. The lifting height reaches 0.645 m. Pick-up of loads is possible at a height of 0.13 m.
If you need to lift a load of 70 tons, you will have to buy not a mechanical, but a heavy-duty hydraulic jack. But for lifting cars with a total weight of 5 tons, the screw bottle model TOR is useful. The height of the pickup is at least 0.25 m. Above this height, the load will be lifted by 0.13 m. The unladen weight of the product is 5.6 kg.
The DR (SWL) model will be able to lift up to 10 tons of cargo. The main lifting tool is a special rail. The pick-up height is 0.8 m. The dry weight of the jack is 49 kg. Rail travel - 0.39 m; but it is impossible to find mechanical manual models with a carrying capacity of 15 tons.
For this value, for example, the pneumohydraulic device Mega is designed. The total carrying capacity of the model reaches 30 tons. The pickup will take place at a height of 0.15 m. The highest lifting height is up to 3 m. Its own weight is 44 kg.
Lifting 70 tons of cargo is possible with the help of the Enerpred DN25P70T hydraulic device. A Russian company is engaged in the development and production of this model. The creators claim that their product can be applied in a wide variety of industries. The stroke of the rod will be 0.031-0.039 m. The working capacity of the hydraulic crankcase is 425 cubic meters. cm.
How to use?
A high-quality jack of the type in question must not only be correctly selected in the store, but also properly operated. Only if this condition is met can a long service life and durability be expected from the device.
The simple design implies an even simpler application of the described product. To start lifting the car, you need to place the jack on the ground under the place where it should rest on the car. On one side of the product there is a fastening for the wrench. You need to install the device with this eyelet towards you. Now we attach the cardan itself and after that we can assume that the device is ready for use.
It is very important for the jack to be installed on a level and solid surface. It is not allowed to install the support platform on a slope, ice, compressed snow. This could cause the machine to fall.
It should be borne in mind that it is necessary to install the product with a slight pushing it under the car, by 2-3 cm.The fact is that as the car rises, the jack will tilt in the direction of the rise, due to this it will roll, and the probability of breakdown will increase ...
Another important point when lifting the machine is to secure one or two wheels with wheel chocks. The handbrake and the transmission are not a panacea for small swaying of the car, and if the car is on a jack of the described type, it can be very dangerous. Any brick or large stone that can be found on the side of the road can be used as an anti-rollback stop. It is still not worth neglecting this "fuse".

Device and principle of operation
The screw jack is a car lift designed mainly for passenger cars. It is compact, stable and has a number of features:
- the design provides for a plane that, when lifted, makes the load stable and reduces the risk of emergencies during repairs;
- the jack can last much longer than the minimum period, subject to the recommended level of loads;
- the tool is resistant to adverse environmental influences.
The design of the jack is simple, its main purpose is to lift and fix the load in one position at a strictly defined height. The tool works on the basis of elementary laws of physics, the torque creates a translational motion that allows you to lift and fix the load. The main parts in the design are: nut, screw and gearbox.
There is also a hydraulic jack with its own characteristics: it is more reliable due to the presence of a mechanical brake in the structure. The gearbox transmits torque to the nut, thereby lifting. And at the right time, when the maximum height level is reached, the braking mechanism is triggered, and the position of the car is fixed.
A modernized manual jack has also appeared on the market, the design of which provides for the presence of special lifting rollers. This makes the structure more reliable as the frictional force is reduced. As a result, the tool lasts much longer and more efficiently than its counterparts.
How to choose?
In theory, any lift with a suitable load level can be used for passenger cars.
But it is important to understand that the carrying capacity should be taken "with a margin". Then lifting even a heavily loaded machine with an old device that has worked a lot will not cause any special problems.
Much attention should be paid to the lifting height. The fact is that it is usually limited to an adjusting screw, and it is impossible to unscrew it to the maximum at one time.
There must be a bypass valve anyway. The compilers of the domestic GOST did not mention this element for nothing. On the other hand, products made elsewhere abroad may not have a bypass valve. Appearance is also important. Any visually noticeable defects indicate either a manufacturing defect or severe wear of the lift.
For purchases, you need to contact only large stores or official branches of manufacturers
It doesn't matter if they are located somewhere in the city or work in the network - this principle is universal. It is useful not to limit yourself to the price tag and advertising assurances, but to study the accompanying documentation
You also need to pay attention to the pickup height, which should correspond to the vehicle's clearance or be selected for reasons of convenience in handling loads. Finally, you need to study the reviews.
