Species overview
Jacks are divided into the following types.
- Mechanical. The simplest lifting devices. The principle of operation is based on the mechanical force to move the working screw.
- Hydraulic. Jacks of this type work on pumping liquid from a container to a cylinder. Through this, pressure is created on the working piston, it moves upward, and the load is lifted.
- Pneumatic. The lifting of the load is carried out by pumping air into the container of the mechanism. The devices are structurally similar to hydraulic jacks. Can be run on exhaust gases by connecting to an exhaust pipe.
- Rhombic. A simple mechanism based on pure mechanics. The design is trapezoidal with a rhombus-shaped lifting part. Each side connects to the other in a movable manner. The sides are closed by the rotation of the stud. In this case, the upper and lower corners diverge. As a result, the load rises.
- Rack and pinion. The basis of the structure is made in the form of a rail along which the lifting mechanism with a pin (pick-up) moves.
- Bottled. The tool gets its name from the shape. The mechanism works on a hydraulic principle. This type is also called telescopic, since the rod is located in the cylinder (hidden in the same way as the separate knee of a telescopic fishing rod).
- Lever. The jack has a main mechanism - a rack, which extends when acting on the drive lever.
- Roll-up. The base of the rolling jack has wheels, a lifting arm and a stop base. The mechanism is driven by a horizontal hydraulic cylinder.
Lifting mechanism service life
But the longer the hoisting device serves you, the more problems arise over time. So, for example, the lifting speed becomes much slower, therefore more effort is required for lifting. And therefore, you should not delay the repair of your equipment for a long time, and having seen only the first signs of such work, it is worth starting to maintain and control it.
Maintenance of the lifting mechanism does not require particularly great effort and time-consuming. First of all, do not forget to add oil. It is known that during operation it can flow out of the oil seals, and it can just get dirty.
From time to time it is worth checking the presence of excess air bubbles in the hydraulic cylinder.It is necessary to pump it without lifting the load so that excess air leaves the device.
Pay attention to the details that rub. For their normal operation, special care is required, which consists in lubrication.
But make sure there are no oil leaks. Inspect and fasteners so that later you do not have any trouble with them. Remember to store the lifting mechanism in a dry place. If you follow all these rules, then the operating life of your lifting device will be long.
Safety when lifting vehicles
Obviously, the most important thing when using a floor standing unit or when performing any work on a vehicle is the personal safety of the driver. Below is a list of some safety guidelines and tips for using the jack:
- Never rely on self-made lifting devices when lifting the vehicle. Always use only a factory car jack of a well-known time-tested brand.
- Before starting lifting work, carefully study the operating instructions of the manufacturer. As soon as the vehicle begins to be lifted with a jack, it must be secured with special devices: you cannot rely only on the hydraulic components of the mechanism.
- Before starting repairs, the vehicle should be rocked a little to ensure that the installation is secure.
- Always raise the vehicle only on a level surface. A room at an angle as a result of an uneven floor creates a tipping hazard.
- Raise and lower the machine slowly.
- Use the permitted points and the lift key on the vehicle specified by the vehicle manufacturer in the technical documentation.
Rolling jack 3 t: which is better to buy?
First of all, when choosing a jack, it is important to pay attention to its parameters. The minimum lifting height of the device must be 130 mm. Heels are most often installed with a width of 4 cm
For a carrying capacity of 3 tons, this is considered normal. Next, it is important to estimate the maximum lift height. This indicator should not exceed 320 mm. With a length of 28 cm, the jack must weigh no more than 7 kg. If we talk about design features, then the lifting mechanism is evaluated first.

The handle should rotate freely. Its upper part is usually rubberized. The outlet valves in the device must be protected. It is not advisable to choose models with openings with plugs. The connection plate should be considered separately. The seam on it should be neat and even. The return spring in many versions is installed at the rear. On average, a model of a good manufacturer will cost around 3400 rubles.
3t jack advantage
The advantages of using such a lifting device are many. Let's dwell on some of them:
Large working stroke.
For me, he is simply irreplaceable at work. I easily increase its height, that's what I like. It's easy to work with him.

Mobility.
I liked this jack because it can be easily moved in any direction. Yes, I forgot to say that it is small. I was attracted by this.
Pavel, car enthusiast, Rostov
Performance. Efforts for lifting are spent less, and, accordingly, in the time interval, everything will be done much faster.
All this allows us to speak not only about a good result when working with such a lifting mechanism, but also about the fact that the master will be able to do a lot, and the client will not have to wait long.
Causes of breakdowns of the rolling jack
Any mechanism during operation can fail. The main malfunctions of the hydraulic jack are:
- complete failure of the device to lower or raise the stem;
- wedging when lifting or lowering;
- oil leak.
If such problems arise, the fixture should be repaired.
If the reason for the breakdown of the device lies in an oil leak, it is necessary to disassemble the device. When disassembling the device, the pistons are removed from it and checked for corrosion. If corrosion or contamination is detected, the damaged structural elements are cleaned and all contaminants removed. Then the stock is checked. If during the inspection it turns out that the stem is bent or has deformations, then repair is considered inappropriate.
Not infrequently, the cause of a jack breakdown can be a failure or clogging of the valves, which take part in the extension or retraction of the working rod of the mechanism. If such a malfunction is detected, this element should be repaired.
How the jack works
Knowing the structure of the lifting mechanism, which has already been described above, it is possible to understand the principle of its operation. So, it is worth recalling that rolling equipment consists of the following elements:
- Lever arm.
- Piston pump.
- Oil reservoir.
- Valve.
- Hydraulic cylinder.
The principle of operation of the jack is as follows: the hydraulic cylinder affects the piston pump in such a way that it drives it. If you need to lift some kind of load, you should press the lever. He is usually tame. It starts the movement of the hydraulic cylinder, which acts, like all other elements in this structure, on the principle of communicating vessels.
A hydraulic cylinder, triggered by the movement of the hand lever, starts the pump, which gradually begins to pump oil into the same cylinder. Due to the gradual filling of the cylinder, the piston begins to move. The valve is triggered and closes so that the oil can no longer flow back.
Therefore, the more this pump works, then, accordingly, more oil will be moved under the piston. This affects what will build up in the hydraulic cylinder. This is how the support itself is lifted, which is exactly combined with the hydraulic cylinder.
During this whole process, the jack must be rolled under the car so that the support is the most stable and reliable. As soon as the car rises to the height that you need, you need to stop pressing the lever with your hand.
Suppose that you have completed all the necessary work and now would like to lower the car. To do this, you just need to find a bypass valve on the pump and open it. Thus, the oil itself will now flow from the cylinder back into the pump, and the jack will begin to lower.
But for the proper operation of the rolling device, it is necessary to observe all the necessary operating rules and, of course, proper care of the lifting mechanism. The instructions are usually included with the purchase of the jack. If all the rules are followed, then such a lifting mechanism will last a long time.
