All about hydraulic jacks with a lifting capacity of 5 tons

Lifting the load manually is not always possible. Especially when it comes to loaded vans or large trailers. To solve this problem, it is important to know everything about hydraulic jacks with a lifting capacity of 5 tons.

A conversation about jacks of such a carrying capacity should start with the fact that these can be stationary or portable models. The energy used for lifting is generated by the movement of the working fluid. Usually there are special brands of oils inside the jack. The liquid presses evenly over the entire surface, so the force is maximal. This design allows you to increase the carrying capacity to the maximum, as well as provide the device with a number of other advantages during operation.

The main parts are the plunger and the acting cylinder. The smaller piston is equipped with a pressure system. It maintains a uniform pressure force immediately applied to the large piston. As a result, the total impact on the plunger increases significantly, it begins to move vertically.

If we consider the most simplified schematic diagram of the design of a 5-ton hydraulic jack, you can find:

• piston drive;

• injection electrical or mechanical system;

• oil filter;

• automatic pressure regulator with a relief safety valve;

• pump that supports the movement of the working fluid.

Simplicity of design and ease of use have made hydraulic jacks widespread and popular. No wonder they are readily used in various fields. Hydraulic lifts are found in ordinary garages and on construction sites of large facilities.

In addition to the already mentioned advantages, it is worth emphasizing such valuable properties of hydraulics as:

• Efficiency is about 80%;

• smoothness of movements;

• increased accuracy of movement;

• increased rigidity of the entire structure.

The most popular is the hydraulic bottle jack. In it, the stem is placed vertically. The device includes a mandatory complex for oil injection.

The telescopic design means replacing a conventional piston rod with a retractable piston. In this version, the lifting height of the load increases.

Diamond systems are attractive because they have 4 key lift points. This is very convenient when you need to raise the entire vehicle above the ground, and not just work with one of the wheels.

But for ordinary work in a private garage, a rolling jack will be more attractive. Its working height is low. But there is a trolley that makes it easier to move. Such a device is also useful for repairing other equipment.

The double-rod jack has one more piston (in addition to the main one). Its carrying capacity is quite high. Such devices are in demand in professional workshops. With their help, it is easier to repair a heavy car, and it will not be difficult to bend any metal structure. But there are many other subtleties that a potential lift owner must take into account.

The most important parameter for any type of hydraulic jack will be its lifting capacity. When selecting it, you cannot focus only on the dry weight of the car. Sometimes it has to be lifted in a tucked state, and even with a loaded trunk and / or interior. It is recommended to add another 10-15% to the estimated full load. Then any unpleasant event will be completely excluded.

Of course, we are talking only about quality jacks. And such copies can be bought either directly from manufacturers and their dealers, or in large chain stores where they sell a variety of goods. But a specialized outlet will still be better than any supermarket.

In practice, the height of the load is of great importance. Moreover we must not forget about such a value as the pickup height - if you ignore it, in many cases the jack will be useless. The dimensions and weight of the lift are important primarily for those who are going to carry it with them by car. However, the need to constantly drag an unnecessarily bulky device in the garage or car service will not inspire anyone. Experts advise not to limit yourself to these criteria.

So, the chemical composition of the hydraulic fluid can be of great importance. The efficiency of work in hot or cold weather depends on this. It is also useful to know the amount of effort that will have to be applied. In order for the pressure relief rate to be maximum, it is necessary to buy a model with a two-way valve. You can find out such characteristics in technical data sheets, in official catalogs, as well as in consultation with official suppliers.

Has good prospects bottle jack MATRIX 50756... It is capable of lifting 5 tons of cargo to a height of 41.3 cm. At the same time, the lower pick-up level is 21.6 cm. This model has one pick-up level. The weight together with the case is 4.8 kg, the proprietary warranty is given for 12 months.

An alternative could be modification "Stella NM 50"... The device picks up a load at a height of 2.5 cm and lifts up to 36.8 cm. The mechanics provides two main working levels. The mass of the device is 25 kg.

The Stella NM 50 model is useful for:

• installation of various structures;

• work on railway tracks;

• construction of highways and various bridges;

• lifting, lowering, clamping or spreading objects (but this jack is not suitable as a support).

Another attractive bottle model - "Sorokin 3.205"... Its lifting height is 17.5 cm. The load can be lifted up to 39 cm. There is only one working level. The total weight of the product is 5.5 kg, its two-stem design is very convenient.

Perfect for tire fitting Rock Force RF-tC50001... The height of work with a load is 7 cm. The lifting height is 73.5 cm. The total weight is 44 kg. The scissor device is pretty rigid.

Alternative - "TOR DG-5"... The stroke of the rod reaches 12 cm, and the height of the load grip is 19 cm. The size of the screw neck is 6 cm. The dimensions of the device are 10x10x19 cm. The support area is 9.6x10 cm.

Lovers of rolling models should take a closer look at the option Nordberg N3205... A pedal is provided that is responsible for fast lifting. The operating handle is completely ergonomic. Its tilt is adjustable with a latch. The designers have provided for the automatic centering of the loaded device.
