In the construction of railway tracks, devices belonging to the category of track tools are used. Such equipment significantly increases the speed and productivity of track workers.
Among the variety of travel tools http://www.zaoportal.ru/product/view/83 distinguish, first of all, the tool:
- manual;
- mechanized.
Hand-held track tools are used for small volumes of work that do not require serious physical effort. This category includes a track wrench, rack jack, rail pliers, claw scrap, track chisel, etc.
A mechanized tool is, of course, in great demand, since it is precisely its use that allows:
- save the current traffic intensity on the railway,
- comply with the scheduled intervals between trains (at least for the main directions).
The power tool has its own classification, which is based on the principle of its design. So, a mechanized tool is subdivided into:
- hydraulic, used, in particular, for transverse sliding and lifting of the rail and sleepers. An example of a hydraulic track tool is a spreader, which is used for distillation according to marks of sleepers (reinforced concrete and wooden);
- electrical - the so-called electrical units that are used to power a power tool with an electric drive. These are, say, mobile power plants, as well as a converter unit and one- and three-phase generators. In addition, the electromechanical track measuring trolley belongs to this category;
- pneumatic, which are pneumatic rail lubricators, wrenches, etc.
Track measuring devices are considered a separate category of devices used in construction, routine maintenance, repair, and restoration of railway tracks. They are used to control the indicators of the geometric parameters of the railway bed.
