Hydraulic jack 2 tons
This type of jack consists of:
- grounds;
- cylinder;
- working fluid;
- pump;
- lever;
- piston;
- valve.
Despite the large list of components, its principle of operation is quite simple. If any breakdown occurs, such a unit can be repaired by yourself. The main thing is to carefully study the design of each individual model.
Components of a hydraulic jack
Hydraulic units are divided into the following types:
- bottle;
- movable;
- electrically driven;
There are many firms producing models of this type, so only familiarization with the characteristics of each individual model will help to make the right choice.
Application
Jacks are primarily used for repairing vehicles in order to hold their bodies or for changing wheels. They can also be used as separate mechanisms for construction purposes, for tensioning wires in electric mains and high-voltage lines. With their help, you can compress a spring, destroy floors in old buildings, move heavy parts or blocks, and use them to repair railways and wagons. The scope of their application is quite wide, which helps to facilitate human efforts.
An overview of the 20 t hydraulic bottle jack is presented below.
What to look for when choosing a tool
When choosing a product, special attention should be paid to maximum lift and stability. First, you should decide on the purpose of using the unit, and then choose the required lifting capacity
The minimum pickup also plays an important role, since when the tire is flat on the car, not all types of jacks can be substituted under it. Especially if it is a low passenger car. It is also worth considering the weight and dimensions of the tool. And, of course, build on financial capabilities. An excellent budget option can be new mechanical units or small hydraulic ones.
How to fix a breakdown
Usually jack breakdowns are associated with improper use of the tool.
Potential problems include:
- slow rise;
- non-working piston;
- termination of the operation of the unit.
If the piston cannot rise or fall, then to repair it, you just need to add oil, since its work is based on it. The level of liquid in the cylinder must be constantly monitored. Slow lifting or jerking during work can be explained by the ingress of air into the tool. With the help of special valves, you need to bleed the accumulated air and pump the jack. If the instrument stops functioning altogether, the problem may be a clogged filter. You will need to disassemble the unit using a special key and clean the filter. If a more complex problem arises, you need to hand over the tool to a professional for service. And if it can no longer be repaired, then you should buy a new jack.
New tool
It is difficult to purchase a high-quality model, because there are many options available on the automotive tools market. But if you carefully study the benefits of each type and read the reviews, you can choose exactly what you need. And if the unit has already been purchased, do not forget that it requires service, otherwise the tool can quickly fail.
The most popular models of jacks 2 t
On a note.
The bottle jack from MATRIX costs little, but is well suited for ordinary car enthusiasts. The hydraulics provide smooth and fast weight lifting without much physical effort.Such a unit has a maximum lifting height of up to 345 millimeters. Moreover, the minimum lifting height only 18 cm.
Despite its small weight and dimensions, Matrix Master 50715 has many disadvantages to use.
The first thing that can be noted in this model is the impossibility of keeping weight for a long time. That is, such a unit requires additional support. The manufacturer recommends placing the tool on a level surface. There are also pluses - the body is made of high-quality material, there is protection against unauthorized weight lifting. The telescopic model lifts the weight up to 380 mm and has a lower pickup height (17 cm). Otherwise, it is completely similar to the previous model.
Also, this company produces rolling units. The Matrix 510209 jack is capable of lifting weights up to 355 millimeters. Its convenient design makes it easy to transport without lifting. Four powerful wheels help this, although the manufacturer also added a handle-holder for comfortable carrying if needed. Such a model, like the previous one, is not able to hold the lifted weight for a long time and is installed only on a flat surface. Therefore, it is necessary to use such a unit only indoors. Another model 51028 with a lifting capacity of up to 2 tons has basically the same characteristics as the previous one. The only difference lies in the maximum lifting height (up to 385 mm) and slightly different dimensions. Often such a unit is sold in a special case and with an additional repair kit.
MATRIX 51028
The Nordberg company is considered to be a very well-known manufacturer of auto equipment. The Nordberg MG-2 tool model can withstand a load of up to 2 tons. It lifts weight up to 310 mm. This model is more expensive than the previous manufacturer, but this is due to the chrome-plated piston of the jack and anti-corrosion coating. This type has a stable rectangular support. The manufacturer claims that such a model can work from any angle.
This unit is not able to hold the weight for a long time, therefore it requires additional support. The rolling model of this manufacturer N3202EC is capable of lifting weight to a height of 385 mm. The unit is quite easy to use and made of quality materials. Such a tool weighs 11 kg and has dimensions of 515 × 205 × 140 mm. Despite this size, it is quite maneuverable and is suitable for both an ordinary car enthusiast and a car service. This model is resistant to skewing and falling loads.
Note!
Hydraulic tools must only be stored and transported in a horizontal position.
The SOROKIN unit with a lifting capacity of 2 tons can lift the weight to a height of 330 mm. Such a tool is quite small, weighing only 2.5 kg. It is only intended solely for lifting, it is not capable of holding weight. In the process of use, additional stands will be needed. The rolling model 3.520 HOBBYLINE from this manufacturer has a lot of positive reviews. This jack is more suitable for home use. Just like the previous tool, it cannot hold the weight for a long time and is installed only on a level support. This manufacturer also produces double-rod types of jacks, the lifting capacity of which is much higher. These units are considered more reliable and are used in auto repair shops or in construction.
What are they?
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, while hydraulic bottle jacks, rolling and electric jacks are especially popular. Each of these types listed above has its own operational characteristics, has pros and cons.
Bottle
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.
Trolley
These devices are equipped with a trolley mechanism that ensures quick and safe lifting. 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.
Electric drive
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.
How to choose?
To choose a jack with a lifting capacity of 20 tons, you must first of all decide on its type of design, having considered all the advantages and disadvantages.
River jacks have the smallest footprint but are great for handling loads that are very low. Convenient for company use with a metal cable for winch purposes. With such a device, you can easily drag the load from one place to another. The devices have the lowest cost and lightest weight in comparison with similar jacks of other design.
The bottle has an average level of cost, thanks to the wide support heel, it is quite stable, working with them does not require much physical effort. In such structures, it is necessary to periodically inspect. They are not suitable for lifting loads from low heights, over time the seal breaks down and oil leaks.
Rolling jacks have a huge variety and are considered the most stable, capable of lifting a load from a minimum pickup height. The design of such devices is quite rigid, thanks to which the load is distributed evenly over the entire surface. But they are the most expensive, very inconvenient for transportation, as they have large dimensions and weight.
