Choosing jacks with a load of 5 tons

To carry out work related to the repair and maintenance of cars, as well as to lift and move loads, special equipment is used - jack... This device is also part of powerful installations in industry and is widely used in construction. Jacks are presented on the market in a huge assortment, but models with a load of 5 tons are especially popular.

The 5 ton jack is a special a device that is designed to lift a heavy load to a height and self-service vehicles... Like any other power tool, the jack works on the principle of hydraulic oil pressure in the cylinder. The user acts on the pump handle, after which the pressure of the working fluid is created in the system and the plunger is pushed out, activating the lifting of the load. A valve is located between the pump and the cylinder; under the influence of the weight of the load, it prevents the oil from flowing in the opposite direction. The mechanism is lowered by opening a bypass valve located between the oil storage tank and the cylinder.

The maximum allowable increase in the lifting height is 10 cm.These devices are available in several types, each of which has its own technical and operational characteristics.

Today, manufacturers offer three main types of jacks for 5 tons: hydraulic, pneumatic and mechanical... Hydraulic devices work by pumping brake or working fluid, on sale they are found as single-valveand two-valve models.

In turn, hydraulic jacks are subdivided into bottle and movable. Bottle type device it is considered the most popular because it has a high lifting capacity. His only minus is small in size, making it unstable. Rolling jack It is used mainly for vertical lifting of cargo, it drives under the car, unlike the previous version, it is convenient to operate, works in any conditions and has good stability.

Pneumatic jacks equipped with a lifting mechanism, which is activated by pumping air into its cavity. As for mechanical type, then it is the simplest lifting equipment, they are often equipped with cars. The price for such devices is low.

Jacks of 5 tons differ among themselves and in design features, depending on which they are divided into five types.

• Rhombic... It is a mechanical instrument of the pantograph type. Its lifting part outwardly resembles a rhombus, and each side of the structure is movably connected to the adjacent one.

• Tablet... This is an affordable jack with a low-profile cylinder hydraulics. The device is connected to a separate hydraulic drive.

• Rack... The design of this type is based on a gear rack, a lifting mechanism moves along it.

• Klinovoy... Both hydraulics and mechanics can serve as a drive in such devices.

• Screw... The movement of the lifting platform in such jacks is due to the rotation of the screw.

Despite the fact that jacks are presented on the market in a huge assortment, universal models are in great demand, the carrying capacity of which does not exceed 5 tons. The most popular designs that have received good reviews are three.

• InforceT90504. It is a bottle type hydraulic device. Pros - ease of use, affordable price. There are no downsides.

• "BelAk 00029"... Double-rod jack, which can lift a load weighing no more than 5 tons. It can be used both in construction and in car service stations. The disadvantage is the price is above average.

• Matrix Master. It is a bottle jack with a hydraulic system, with the help of which it is possible to carry out repairs of passenger cars, as well as medium-duty vehicles. Equipped with a reliable relief valve, thanks to which the load is held in a stable manner. There are no downsides.

In order for the jack of the considered carrying capacity to reliably serve a long time, when buying it, you need pay attention not only to the design features, but also to the intended purpose. One of the main criteria when choosing equipment is considered lifting capacity, since each model has its own minimum and maximum indicators.

Also deserves special attention lifting height, usually most models are designed for 40-50 cm. This is enough to change a wheel or provide easy access to the handbrake cable. In addition, it is worth checking with the sellers and lifting speed, which directly depends on the working stroke. The larger it is, the better the lifting device is considered. It is also worth studying the reviews about a particular model, since it is absolutely not necessary to overpay only for a well-known brand.

In the next video, you can familiarize yourself with the characteristics of a hydraulic jack with a lifting capacity of 5 tons.
