Jack - a necessary tool for car drivers, which will certainly help out on the road and in case of repair work in the garage. A feature of this device is that it lifts loads to the desired height and allows them to be fixed in this position.

Peculiarities

Recently, they are in great demand jacks with low (side) pick , since they make it possible to lift a load from a low working height. The design of such models is quite stable and reliable . Moreover, they differ large-scale functionality … Lifting devices of this type are used not only for car repairs, but also during construction and other work related to the lifting of large-sized metal or other structures and loads.

Low-grip tools are equipped with devices (bayonets) that make it possible to pick up a load from a very low height (distance from the ground surface, floor, plate to the bottom of the load).

The design also includes the so-called springs , which quickly bring the bayonets to their original position. In addition, the uneven surface of the jack prevents large objects being lifted from sliding, thereby ensuring safe operation. BUT special lever allows you to use the greatest effort for lifting.

Views

Low grip jacks are divided into several types, which, in turn, differ in their design, maximum carrying capacity and characteristic functions.

Hydraulic jack

This device works by using a special fluid that resists pressure. With the help of a pump, this fluid is pumped into the hydraulic cylinder. T This design allows you to prevent sudden movements, provides smoothness and the function of fixing the load in the desired position.

The main feature of the device using liquid is the presence of a lifting arm at the lowest part of the cylinder.

This arrangement helps to lift loads from a very low position, where the gap is almost invisible.

Thanks to modified methods, hydraulic tools can be used from absolutely any spatial location , and with the help of a grooved rod, resistance is provided, therefore the load cannot just slip off . And also it should be noted the ability of the tool lift a heavy load to a fairly large height . The weight of the cargo can reach 25-30 tons, and the lifting is carried out from different sides. These jacks are usually designed with 360 degree pivot point reversibility.

A number of performance characteristics determine its differentiation from other types:

• it is not recommended to use loads with dimensions larger than the instructions allow;
• a central reference point is predetermined, to which all the weight is distributed, while the tool must be vertically on a stable surface;
• the valve of the reservoir, which contains all the liquid, must be closed, and only after that the oil must be pumped using a pump; you need to try to raise the piston slowly, without sudden movements, and at the maximum height the device will stop by itself;
• to complete the work, you will need to turn the valve lever, but again without any jerks, otherwise a dangerous situation may arise in which the supporting part will not withstand the load;
• if the work is carried out in conditions when the air temperature is below zero, then you will have to carefully select the brand of oil (VG22 or SYB1104-62);
• it is necessary to constantly monitor the liquid level in the valves in order to reach the maximum height, otherwise the load simply cannot rise;
• it is important to know that safety while working with such devices plays an important role; protect your hands and feet by not pushing them under the jack.

Hydraulic bottle jack

A versatile tool that is widely used in construction and during automotive repair work . The bottle jack has a distinctive design that separates it from other low grippers. Let's list its main parts.

1. Main hydraulic cylinder.
2. Safety valve.
3. Suction valve.
4. Storage of working fluid (oil).
5. Functional (working) chamber.
6. Lever for pumping working fluid.

For this model to work, everyone's well-known Pascal's law is applied - the force of pressure, which is directed to a gas or liquid, is directly proportional to all directions without any distortion.

The principle of operation of the hydraulic cylinder quite simple and consists in the fact that the oil is pumped from the reservoir in which the working fluid is stored to the functional chamber, where pressure will be created to lift the main cylinder.

Consider characteristics a jack shaped like a bottle. Minimum and maximum lifting capacity devices range from 2 to 100 tons.

The smallest distance this tool can pick up a load is inferior to a hydraulic jack. That is, before purchasing a bottle lifting tool, you should pay attention to the ground clearance of your car . If it has a very low clearance, then such a device will not work. Another criterion is important - the height at which the device lifts and fixes the load.

This is the main specificity of bottle jacks, since they allow you to set the load at both minimum and maximum height.

There are two basic rules to follow to avoid jack breakage

1. Regularly make sure that the oil does not leak, while getting on parts with rubber or seals. In a leaking state, the tool will not be able to lift the load.
2. The dryness of the component gaskets, into which oil may seep, must be monitored. In this case, air will be inside the structure, which will interfere with the pressure in the cylinder, which will lead to a dangerous situation.

Hydraulic rolling jack

This device is the most common and widely used among jacks that work on a liquid basis. Their distinctive features are lifting height and lifting capacity . And the design is specific by the presence wheels , thanks to which the tool rolls under the car and picks up.

The superiority of the rolling jack is that he picks up from a height of 5 cm , and its application is possible even in hard-to-reach places.

There are jacks of different levels of functionality, which can be used with all kinds of car models . For work in workshops, hydraulic trolleys are manufactured, equipped with special levers , allowing you to work while standing and at the same time not exert significant physical effort.

Model overview

When choosing a jack, it is necessary to consider such points as country and manufacturer's brand , as well as vehicle model . It is also important for car owners how mobile this device is, so you need to find out about it weight and dimensions.

Having considered the popular brands of manufacturers and the most commonly used jacks, several of the best models can be identified.

Matrix Master 51028

It is a hydraulic rolling jack that easy to operate , compactly located in a special case. Designed for lifting passenger cars. The jack is equipped with protective device in the form of a valve, which prevents overloading of the tool. It can be used both in workshops and on the road for repairing cars.

The carrying capacity of this model is 2 tons.

Hobbyline jack

These low grip bottle jacks designed for picking up loads of a high weight category . But due to their rather large dimensions, they are difficult to transport, so they are usually used in service stations. The comfortable handle allows you to fix the mechanism in a convenient place for work, without any special effort.

DA5P120K

The model is considered one of the best among the low-lift jacks . Was designed for fixing and lifting oversized cargo in the production of installation and repair work. Designed for stationary use in workshops or garages. The design includes grips for lifting weights, springs with the ability to return the rods to their original position, as well as pumps that create fluid pressure in the chamber of the working cylinder.

The DA5P120K jack is made exclusively from strong, heavy and reliable materials, achieving, among other things, the stability of the center of gravity.

The support part allows lifting loads up to 5 tons, and the side parts are capable of only 2 tons. The hydraulic cylinder complete with the built-in pump and control panel makes it possible to work practically in automatic mode.

How to choose?

When choosing a jack, it is necessary to consider such a key point as intended purpose of the unit (where it will be used: at home or by professionals in the service station). Nowadays, a whole range of options are offered.

Criteria for selecting a suitable device

1. An important component is lifting capacity … It is calculated primarily depending on the mass of the vehicle, in relation to which the jack will be applied. After that, in order not to miscalculate with the choice of the lifting mechanism, about 300 kg should be added to the result obtained. This will help prevent future damage to the device.
2. Lifting height . This indicator determines how far the device can approximately lift the load. It is important to note that you need to find out how reliably the device can fix the unit.
3. Pickup height … This indicator characterizes from what height a low-profile jack allows you to pick up a large-sized unit. This is very important for those whose machine has very low clearance (in which case a hydraulic mechanism with a low pickup is perfect).
4. Weight and accessibility of the device for transportation . The jack can be useful not only for use in garages, but also when traveling long distances.
5. Reliability and sustainability . These factors are more dependent on the area of the center of gravity and the pivot point. If these elements are properly distributed, the device is able to support the intended weight.
