How to use?
Telescopic jacks are usually used for trucks, cars, buses and other equipment. Thanks to the units, you can quickly and easily raise a part of the car above the ground and replace the wheel and pads.
To ensure the correct operation of the jack, you need to adhere to certain rules for its operation.
Do not use the device in cases where the weight of the load exceeds the lifting capacity of the tool. This is traumatic and could cause the jack to break.
Before starting to work with the device, it is necessary to determine the center of gravity of the load that is planned to be lifted. In addition, it is required to choose the most suitable position, only then can the jack be installed in an upright position on a flat and solid surface. If necessary, you must additionally put a lining of hard material under the bottom.
It is necessary to operate the device from the complete closure of the exhaust valve, for which the end of the jack lever is used. It is inserted into the pump piston socket and pumping is started, after which the piston rises smoothly. When the maximum lift is reached, the hydraulic arm will begin to lock.
If you rotate the exhaust piston, it will begin to descend. It is recommended to turn slowly to avoid accidents.
In the case when several lifting devices are used at the same time, it is very important to ensure that the specific load level is not exceeded, and the lifting speed of all jacks is the same.
When using a telescopic jack, it is important to take into account the ambient air temperature, if it is from -5 to -20 C, then it is advisable to pour oil into the system that is resistant to low temperature conditions. In addition, it is necessary to constantly monitor the oil level in the piston, if it is not enough, then the required lift will not be achieved.
When lifting a load, it is strictly forbidden to be under it, as well as to push different parts of the body under it
Low-lift jacks cannot be used to secure the load at the selected height.
In the next video, you will learn how to choose the right jack.
Screw Bottle Jack Models and Manufacturers
The TOR firm produces quite expensive models, but this price is quite consistent with the quality of the product. The most popular jack from this manufacturer is TOR 3.2t. It is well suited for car enthusiasts, as it has small dimensions and weight. With a lifting capacity of 3.2 t, it can lift loads up to 335 mm high. This unit weighs only 4.3 kilograms. These jack models are very well suited for intensive use.
The next in the line of tools of this manufacturer is TOR 5.0t. This unit has a large carrying capacity (5 tons) and dimensions. In this case, the lift height is increased to 380 mm. This jack is better suited for heavy vehicles such as off-road vehicles. Weighing 5.8 kilograms, it fits perfectly in the trunk of any car.
Units from 10 to 32 tons of this manufacturer are designed for large vehicles, as well as for use for construction purposes. Their dimensions and weight are much higher than those of previous models. These jacks can be installed even on uneven surfaces. Thanks to the quality material, they can be used in all weather conditions.
Note!
The screw bottle jack from 10 to 32 tons does not require additional support and can hold the load for a long time.
The Skyway S01803001 unit has both many advantages and disadvantages. The mechanical screw telescopic jack has a lifting capacity of 2 tons. Its weight is only 3.9 kg, the size is 160 × 118 × 180 mm. With such insignificant indicators of weight and dimensions, it can lift loads up to 390 mm. Due to its compactness, it is well suited for use by motorists. The flaws of the model are that Skyway S01803001 is not able to hold the load for a long time. When using it, it is necessary to add additional supports. The load lifted by such a unit must not be moved. Also, you must not stand under a jacked-up machine without additional support.
Jack of the firm Skyway
The BIG RED SJ25 screw jack can lift loads weighing up to 25 tons. This unit is more often used in construction and repair areas. Despite its small size, it is very stable and can understand weight up to 669 mm... This model has a massive handle, thanks to which the BIG RED SJ25 is easy to carry. Jacks of this type are well suited for frequent indoor and outdoor use.
Note!
The sliding screw has a special rubber pad, so it does not slip when the load is lifted.
The BIG RED SJ25 is able to hold the load for a very long time; additional supports are not needed in this case.
Before choosing a jack, you need to decide on the scope of its operation.
Particular attention should be paid to the maximum lifting capacity and the level of lifting of the load.The quality of the material also plays an important role in the choice
In such models, corrosion protection must be present. Only in this way will the lifting mechanism be able to serve for a long time and not break.
Design features and principle of operation
The principle of operation of a hydraulic type jack is the use of a working fluid that cannot be compressed (for example, oil). The fluid rises into the hydraulic cylinder - this is done by the hydraulic pump - thanks to this, lifting of heavy and extra-heavy loads becomes smooth, without jerking, and the jack rod can be stopped anywhere.
Rack and pinion hydraulic jack as a versatile lifting device
Note!
The location of the lifting arm, located at the bottom of the tool, allows you to lift loads in such cases in which the lower position of other types of jacks is not enough - practically from the floor.
Due to the low height, there is an excellent possibility of using low hydraulic jacks in confined spaces when it is not possible to use a different type of device. This includes situations related to the installation and alignment of heavy equipment and structures, viaducts, bridges, etc. The low weight and small dimensions of the low jack facilitate operation.
On a note!
Spring-return versions can be used in virtually any interdimensional position. And the grooved support part will prevent the load from slipping.
Other features include the outstanding lifting capacity, which can reach 25 tons, work in all planes, the ability to rotate the body 360 degrees.
The characteristic features of this type of hydraulic jack with a low pickup predetermine a number of differences in its operation:
It is forbidden to use the jack in cases where the weight of the gravity exceeds the carrying capacity of the tool.
It is necessary to determine the center of gravity of the load that needs to be lifted, choose the most optimal position, then install a low-type jack in an upright position on a solid, flat, rammed plane
It will be important to pay attention to the condition of the surface on which the rigging device will be installed. If necessary, place a firm pad under the bottom.
Close the exhaust valve completely before starting work - the end of the jack lever is used for this.
It must be inserted into the socket of the pump piston and start pumping. In this case, the piston will begin to rise smoothly. The design of the hydraulic arm stops its lifting if the maximum lifting height is reached.
To lower the piston, the exhaust valve must be cranked. Rotate slowly to avoid accidents.
When using multiple jacks at the same time, it is important to maintain the same lifting speed and the unit load should not exceed the maximum lifting capacity of the unit.
If the air temperature of the working environment exceeds -5 ° C, preference should be given to oil of the SYB1104-62 or VG22 brands. If the temperature range varies from -5 to -20 ° C, you must use oil brand SYB1206-56
Alternatively, SYB1207-56 can be selected.
It is necessary to monitor the level of oil in the piston: if it is insufficient, the required lift will not be achieved.
When lifting a load, it is forbidden to be under it, to put your arms, legs, and other parts of the body under it. The low-lift jack cannot be used to fix the load at a certain height.
The best car jacks - which company to buy
All companies included in our rating have an extensive distribution network throughout the CIS, so you can buy their goods in every major auto shop. On the manufacturers' website, products are also sold, but mostly only in bulk.
The choice in favor of these firms will definitely not be a mistake:
- Autoprofi - the manufacturer offers all the goods necessary for motorists, from auto chemicals to jacks. The products are manufactured in Russia, so the prices for them are quite adequate.
- Matrix - its assortment includes rack, rolling, bottle models with a carrying capacity from 2 to 20 tons. Here both motorists and service station owners will find a suitable option for themselves.
- Kraft - the company began producing goods for car owners back in 1993. During this time, she replenished her piggy bank with tool kits, lighting equipment, spare parts and various accessories for cars. The company is balancing on the edge of a budget firm and a mid-price segment.
- Airline is a well-known Russian manufacturer of automotive goods. The line of jacks he has is very decent, it includes more than 50 modifications. But the priority of the company is the development of bottle hydraulic models with a large tonnage (from 2 to 50 tons).
- Sorokin - this manufacturer closes the top five, but he took the last place only because of the high price of his goods. It is mainly used by the owners of service stations. According to this indicator, the company is inferior to competitors, but ahead of them due to the presence in the range of rather rare electro-hydraulic models.

Features of the hydraulic double rod jack
The double rod hydraulic jack works on the basis of Pascal's law. Its design contains 2 interconnected vessels, which contain a special hydraulic oil that cannot be compressed. When pumping, oil from one vessel enters another through a valve, as a result of which an excess pressure is created in the second. It is this that raises the jack rod up. A bleed valve is used to return the piston to its original position. It is applied to return oil into the original container.
Double-rod bottle jack - a universal tool in any situation
On a note.
A distinctive feature of a double-rod jack is the presence of two functional rods, which allow lifting the load to a greater height than single-rod mechanisms.
This gives an excellent opportunity to lift to a solid height, for example, cars that have a fairly low ground clearance. Also, telescopic double-rod jacks can be successfully used in other industries - in presses, pipe benders, etc.
The device itself consists of the following working nodes:
- The tank is cylindrical: it contains the working fluid, usually special hydraulic oil.
- Piston: driven by oil pressure, which is pumped from the first vessel.
- Distributor: Its task is to distribute the pressure in the right direction.
- Oil cleaning filter: This filter removes dirt and other particles from the working fluid. He is also responsible for the absence of areas with high viscosity.
- Discharge valve: it allows you to maintain the required pressure in the working area. This is a predetermining factor when lifting a load to a certain height and fixing it in this position.
- Pressure relief valve: Its function is to return the telescopic stem to its reverse position.
- External pump: pumps oil into the cylinder and maintains the required pressure. Today, gear, plate and piston pumps are used.
Pros and cons of a double rod jack
The tool has a number of advantages that distinguish it favorably from a huge variety of other varieties.
So, they include the following:
- Impressive lifting capacity with small dimensions - some double-rod jacks can lift up to 200 tonnes.But the most popular among motorists are two-rod hydraulic bottle-type jacks for 2 tons: such a carrying capacity is enough for most cars.
- Low tool weight.
- Stability and rigidity of the structure.
- High efficiency - up to 80% of the applied effort goes into work.
- Smooth lifting and lowering.
- No need to put a lot of effort on the lift handle when understanding a solid scale.
- Cheapness.
Along with the advantages, there are a number of disadvantages:
- Comparative design complexity.
- The need for maintenance.
- Low lifting height.
Despite the aforementioned disadvantages, the tool more than pays for itself with exceptional efficiency, high reliability and ease of use.
Two-rod telescopic jack
Note!
There are also rolling, screw and flat jacks that run on hydraulic oil on sale. They differ in design and in some parameters (lifting height, lifting height), however, the principle of operation is the same for all hydraulic jacks.
Views
The described product does not have many types of its execution, since the design is very simple and reliable. However, there are some differences. In addition to the obvious difference in lifting capacity, products may differ in different heights when lifted. In order not to increase the minimum lifting height, but to increase the maximum stem overhang, the engineers decided to make a stem consisting of 2 or even 3 sections, which slide into one another, like in a retractable antenna. Bottle jacks can be conditionally divided into:
- single-pin;
- two-rod;
- three-rod.
In addition to the number of rods, sometimes you can find a jack of the described type with a screw pump. These are quite rare models, but they also deserve attention. They can be useful if they need to be installed in an inconvenient place and it is very difficult to pump with a conventional pump. In this case, a metal cardan will come to the rescue, which is supplied with the jack itself.
