Features of jacks with a lifting capacity of 2 tons

Every car enthusiast should always have at hand such an indispensable tool as a jack. However, this device is used not only for lifting a car: it has found wide application in the construction and repair industry. And although there is a huge selection of jacks, the most popular are models with a carrying capacity of two tons. The role in this was played by their following advantages for most consumers: compactness, lightness, endurance and quite democratic cost.

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 cars with a low seating position to be lifted;
• hydraulic models require a level and solid surface.

All hydraulic jacks with a lifting capacity of 2 tons differ not only in the principle of operation, but also in their individual design. At the same time, all of them are united by one feature - the use of a lever during operation.

The main components of the bottle type hydraulic jack are:

• support-base (body sole);
• working cylinder;
• working fluid (oil);
• pickup (the upper part of the piston, used to stop when lifting a load);
• pump;
• safety and pumping valve;
• lever arm.

Despite the fact that the list of components of the device is large, its principle of robots is quite simple. The working fluid is pumped by a pump from one reservoir to another, building up pressure in it. This is to drive the piston. The valve performs a shut-off function - it is responsible for blocking the backflow of the working fluid.

The device of electric jacks represents a single mechanism of moving parts. These types are equipped with a geared motor. Such a lift can work either from the electrical network or from a battery.

As for pneumatic devices, a compressor is provided in their design, and outwardly such jacks resemble a pillow. The principle of operation of the pneumatic jack is similar to the hydraulic options, only the working medium here is the air pumped by the compressor.

Nowadays, a jack with a lifting capacity of 2 tons is considered the most obligatory tool that should always be in any car. Such units are presented on the market with a huge selection, with hydraulic bottle jacks, rolling and electric car jacks being especially popular. Each of these above types has its own operational characteristics, has pros and cons.

This type of jack got its name because of the external similarity of the design with a bottle. Here the slave cylinder with a stem protruding from above stands out sharply. Such a lift is often called telescopic, since the rod in the initial position is hidden in a cylinder, which is similar to the knee of a telescopic fishing rod. There are variants with one and two rods. Much less often, you can find models with three stems on sale.

Such devices are equipped with a rolling mechanism that provides quick and safe lifting of the load to the desired height. Rolling jacks are ideal for use in garages of car enthusiasts and professional car service workshops. This type of device can have different carrying capacity, but the most common is 2 tons.

The working mechanism of electrically driven jacks is driven by an electric motor. There are models that can be powered by a car cigarette lighter or directly from a battery. Manufacturers often equip them with a control panel.

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 copes well 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.

• "Stankoimport NM5903". The jack has a manual drive, a hydraulic system, and a cardan mechanism, due to which the lowering of the load is carried out smoothly. The surface of the jack is covered with a special protective layer against scratches. Advantages of the model: convenient use, reliability, durability, reasonable price. There are no downsides.

• Rock Force RF-TR20005. This model is able to cope with lifting loads up to 2.5 tons, its pick-up height is 14 cm, and its lifting height is 39.5 cm. The main advantage of this unit is its compactness, since when folded it takes up a minimum of space. In addition, the device has a swivel handle for working in confined spaces.

• Matrix Master 51028. This is a very popular model among car enthusiasts as it is compact and comes with a convenient storage case. This jack is equipped with a safety valve, hydraulics and a lever handle that minimizes force. This model appeared on the market recently, but managed to prove itself. The only drawback is the high cost.

• "ZUBR T65 43057". Jack with two pistons designed for lifting low-slung vehicles. It is produced in a metal case and is completed with a rubber support. This construction weighs about 30 kg. The pickup of the unit is 13.3 cm, and the maximum lifting height is 45.8 cm. The disadvantage is its large dimensions, which complicates transportation and storage.

Even before purchasing a high-quality jack with a lifting capacity of 2 tons, it is important to determine its purpose and find out all its capabilities (maximum lifting height, minimum gripping height, lifting capacity) and compliance with the technical characteristics of the vehicle parameters.In order to correctly calculate the carrying capacity of the device, you first need to find out the weight of the car itself, taking into account the daily workload. For cars and SUVs, it is best to purchase bottle-type jacks.

The lifting height of the device also plays a huge role, it is determined by the distance from the jack support point to the maximum height that should be suitable for changing wheels. The average height can be from 300 to 500 mm. As for the pickup height, this is also one of the important indicators of the device.

Additionally, you need to clarify the type of device drive. The most convenient to use are hydraulic bottle jacks. They are equipped with a special lifting handle and do not require much effort. In addition, it does not hurt to read user reviews about a particular model, as well as take into account the manufacturer's rating. It is best to buy equipment of this type in company stores that give a guarantee for the goods and have quality certificates.
