Peculiarities
The glass jack is designed to grip and hold products with even and smooth surfaces for a long time. Despite the fact that this is a very useful device, which is widely demanded in various industries, not all users know what a glass jack is and what its structure is.
It should be noted that the tool itself is distinguished by exceptional wear resistance and durability. Glass jacks with a plastic and aluminum body are widespread - such products are able to maintain their appearance and performance for a long time even in areas with high humidity levels. In fact, such a device works by analogy with powerful suction cups - they attach to the surface of the glass and thus hold it in an elevated state.
Glass jacks can be produced in different versions, each of which is designed for a certain weight, depending on which the device can have one or more cup-shaped suction cups. For ease of transport, the device has a plastic handle
We draw your attention to the fact that it can be difficult and even dangerous to lift such a jack by hand - very often the glass is damaged. To prevent this from happening, the design provides special clamps that gently press the suction cups
Thus, when they are lowered, the bowls are securely fixed to the surface.
Some users are afraid that the handle will come off and the glass will fall off while carrying it. To minimize these situations, it is best to use double or even triple jacks. In this case, even if one of the suction cups moves away, the rest will act as a safety net.
You can move not only glass panels, but also some other materials with a smooth surface, such as artificial stone, plywood, tiles, as well as some other building materials. The following situation often happens: the floor is lined with a waterproofing layer, and it is extremely undesirable to move on it. At the same time, the elements of the future tiled floor fitted to each other are fixed from above. Of course, you can number them and move them to another room, in order to subsequently grease them one by one and put them back. However, it will be much easier to use a glass jack - to lift fragments of the floor with it, spread it with a fixing compound and immediately put it back in place without disturbing the overall installation.
The glass jack can be used when transporting furniture if there is nothing to grab onto. The device is capable of lifting heavy porcelain stoneware countertops. In addition, the attachment can be used to lift materials to a height.
How to choose?
The choice of the optimal model of a glass jack directly depends on several important parameters.
Device material
The mechanism can be plastic or aluminum
When choosing a particular model, special attention should be paid not only to the material, but also to the shape of the case. Be sure to pick up the element and make sure of its good and well-thought-out ergonomics.
There is an opinion that a metal case is heavier than a plastic one - this is far from always the case, especially if aluminum is used for its manufacture. Nowadays, you can find quite reliable plastic cases, which are very convenient to work with. Another undoubted advantage is the presence of rubber pads on the handle.
Number of suction cups
The more there are, the higher the total carrying capacity will be.It should be noted that in a professional environment, single jacks with a single suction cup are almost never used - in a reliable tool there should be at least two of them, and even better if there are the same number of handles. This design allows you to easily lift a glass panel weighing up to one centner. Most often, craftsmen buy a glass jack with three suction cups arranged in a triangle shape. With the help of such a design, it is not only convenient to move the overall glasses, but you can also easily turn them on one side if necessary.
If you plan to move slabs weighing up to 150 kg, then it is better to entrust this matter to a glass jack with four suction cups.
The same structures allow transporting the glass to a great height, however, in this case it is very important to make sure that the jack itself has a sufficient supply of capabilities. It is best to choose such a model in which there is the necessary reserve of carrying capacity - only in this case it is possible to ensure a sufficient level of reliability and safety of glass movement
The design features of the case may be reflected in the total cost of the product.
Keep in mind that the suction cups can fail much earlier - this happens if you accidentally scratch their inner surface. However, experienced glaziers know very well how diaphragms can be repaired quickly and inexpensively. To do this, you should always keep a jar of cyanoacrylate glue, for example, Cosmofen, on the farm. Having processed the inner surface of the rubber with such a composition, you will not only be able to continue using the tool without any problems, but will significantly expand the functionality of your glass jack. After such treatment, it will be able to grip even corrugated and uneven surfaces.

Depending on the level of complexity of the work performed and the dimensions of the glass, a variety of types of glass jacks can be used. Manual is designed for transporting sheet glass, has a relatively low weight in the range from 2 to 25 kg. Manual installations with a vacuum pump allow you to transfer glass leaves weighing 40-80 kg. Power glass jacks are mainly used in addition to cranes and can handle glass slabs weighing up to 500 kg. Such devices are widely in demand for facade glazing.
Despite all the existing differences in the design features of different types of glass jacks, they are all based on the same operating principle. In the functional plane, a zone with reduced pressure is artificially formed.
