Rack jack. general information

Rack jack - mobile (portable) device, which allows you to lift various loads to the height. This type of device is actively used in many areas due to a variety of types of structures, and a distinctive feature of other lifting mechanisms is that they are placed under the load, and not above it. The jack rack is very popular among motorists, due to its compactness and simplicity of the device. They can have a cast iron or steel rod, and they can lift the cargo to the height of this very rod.

In general, the jack rack in all spheres is quite popular. The essence of its mechanism lies in the fact that in its design there is a rack with a special support cup. The mechanism is driven by the rotation of the handle, which moves the load along the rack with the support cup.

Jack Rack DR-5 is designed to lift the load by means of a manual drive. This type of device is able to lift the load to a small height with a high degree of accuracy, while requiring a minimum amount of physical effort. Jack Rack DR-5 has in its functional equipment a cargo brake, the main task of which is to ensure the retention of the lifted cargo. It is important that in this case, the proportional load on the axis of the rail is observed.

Distinctive features of these mechanisms is that they are a compact device that does not require any complicated manipulations in operation. When lifting the load, a high level of smoothness is ensured. Due to the extended base, the jack has increased stability, and its payload is 5 tons. All these positive moments make this device indispensable in some areas of industry.

The jack rack DR-10 has a ratchet mechanism that ensures safe operation and fixes the load during lifting. High maintainability and reliability make such devices ideal for use in difficult technical conditions. The lifting capacity of the DR-10 jack is 10 tons, which expands the scope of its application in comparison with the previous presented type.

Rack jack allows to stop lifting of cargo at any height, thus the cargo will be reliably fixed. The scope of the use of lifting mechanisms determines their technical capabilities: the type of device, load capacity, availability of additional functions and so on.

As noted above, such mechanisms have become most popular among motorists, and especially those who prefer flat roads off-road. In such extreme conditions, this type of lifting device is an ideal assistant.

The jacks, capable of lifting more than 10 tons, are used mainly in construction work and for laying railroad rails. They can also be used not only in the horizontal, but also in the vertical plane, with the main condition being the presence of a reliable support. The maximum possible lifting capacity of rack jacks is 20 tons.

In addition to rack and pinion jacks, there are also screw, hydraulic and pneumatic types.
