Rack jack is a mobile (portable) device that allows you to lift various loads to a height. This type of device is actively used in many areas due to various types of structures, and a distinctive feature from other lifting mechanisms is that they are placed under the load, and not above it. The rack jack is especially popular with motorists, due to its compactness and simplicity of the device. They can have a cast-iron or steel rail, and they can lift the load to the height of this very rail.
In general, the rack jack is quite popular in all areas. The essence of its mechanism lies in the fact that in its design there is a gear rack with a special support cup. The mechanism is set in motion by the rotation of the handle, which moves the load along the rail along with the support cup.
Rack-and-pinion jack DR-5 is intended for lifting loads by means of a manual drive. This type of device is able to lift a load to a small height with a high degree of accuracy, while requiring a minimum amount of physical effort. Rack jack DR-5 has in its functional equipment a cargo brake, the main task of which is to ensure retentionlifted load. It is important that in this case, a proportional load on the axis of the rack is observed.
Distinctive features of these mechanisms is that they are a compact device that does not require any complex manipulations in operation. When lifting a load, a high level of smoothness is ensured. Thanks to the extended base, the jack has increased stability, and its load capacity is 5 tons. All these positive aspects make this device indispensable in some industries.
Rack rack jack 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 jack DR-10 is 10 tons, which expands the scope of its application compared to the previous type presented.
The rack jack allows you to stop lifting the load at any height, while the load will be securely fixed. The scope of application of lifting mechanisms is determined by their technical capabilities: type of device, load capacity, availability of additional functions, etc.
As noted above, such mechanisms are most popular among motorists, and especially those who prefer off-road to smooth roads. In such extreme conditions, this type of lifting device is the perfect helper.
Jacks capable of lifting over 10 tons,are used mainly in construction work and for laying railway rails. They can also be used not only in the horizontal, but also in the vertical plane, while the main condition is the presence of a reliable support. The maximum load capacity of rack jacks is 20 tons.
In addition to rack jacks, there are also screw, hydraulic and pneumatic types.

Rebar classes: general information
Reinforcement is an important component of reinforced concrete structures, designed to accept heavy loads. It can be said that the reliability and performance of structures largely depend on the strength and endurance of these steel rods. Reinforcement classes reflect mechanical, chemical and physical properties, rolling technology, post-rolling treatment methods, corrosion resistance, as well as a number of other parameters of these load-bearing elements of any modern structure
