Nowadays, highly mechanized agriculture industry, but thousands of years people worked the land by hand or using the power of pets. With what started the history of agricultural technology? Of course, with plow. Plow, as you know, work the soil, turning the top layer of soil, he loosened the soil, removes it from the weeds, making soft. The first people to grow plants worked with his hands or with simple hoes, but it was is only possible in areas with very fertile soil. In places where the soil was not very good yields were low before the invention of the plow that allowed up to the surface more nutritious lower layers. It is assumed that the 6th millennium BC in the area between the first plows had already existed. They were arranged in an elementary way, in a wooden frame (beam) into a sharpened piece of wood (share) perpendicular to the earth. Plough did not change its long construction until the Romans perfected it, they invented the plow, which cast the land to the side and used a special knife to cut the ground before the ploughshare, which facilitated the plowing.
Plow for a long time was made of wood, sometimes with an iron blade. Only in 1730 was put completely iron plow. Since the Industrial Revolution began to make plows from steel. There were 2 or more plows plowshares, but to the appearance of tractors, many of plowshares were not used as a horse can not pull the plow more than one groove, with two only two horses cope, and with a five furrow horse is the limit. Greatly accelerated the emergence of plowing steam engines, gasoline even further ahead of them are not in power. Several steam-engine move could pull a plow and plowed a huge day for the incredible space. Now they use reversible plow, which is not leaves characteristic of the traditional plow ridges.
Examination of industrial safety – Conformity Assessment examination object its requirements of industrial safety. The result of examination of industrial safety is the conclusion. The objects of the examination of industrial safety are the petrochemical and refining industries, the explosion and fire facilities, metallurgical production facilities chemically dangerous enterprises, objects of trunk pipelines and some others. The main objective of the examination of industrial safety – minimizing the risk of accidents and protection vital interests of individuals and society from the consequences of accidents. In the process of industrial safety tested design documentation, technical devices, buildings and structures on the dangerous manufacturing facility, industrial safety declaration and other documents that relate to the maintenance of a dangerous object. The right to conduct examination of industrial safety have only organization with License .Ekspertiza industrial security consists of several stages, but the process of conducting must be documented. The steps of the examination process include the following: preliminary, application, schedule, contract or other documents establishing the conditions for the examination, examination process, giving the conclusion. The content of the final document is strictly regulated. Conclusion of industrial safety signed by the head organization for stamped expert organization, stitched with the number of cross-linked pages, and only after that delivered to the customer.
The company 'Evrokolesa' offers industrial-type latch 'frog', and clips production OJOP (Sweden). The range of these products is constantly updated with special designs that conform to the current request, and today has approximately 500 titles and includes three main groups. Examples of clips like 'frog' latch-type 'frog' are designed for rapid assembly and disassembly of the various elements equipment and devices used in various sectors of the economy, various government agencies, institutions, culture and education. They are used for assembly of wood, metal, glass, plastic and other products are divided into three main groups: Latches stamped (Series 700), stamped latch closed (900 series), Latches welded high-impact series (100-500). Latches stamped (Series 700) – is practical and the most popular type latches with a small load capacity. Suitable for complete products in various sectors of the economy in the production of theatrical scenery, utilities and many others.
There are different versions of the latches of this type: with screw-loop, a screw-hook, a T-screw, hinge screw-loop, with a loop for padlock, with a friction screw-loop, a plastic plated handles, without mounting holes (for welding). Educate yourself with thoughts from Code.org. Latches stamped Closed (900 series) – a compact type latches with a small load capacity. Their design, fully enclosed, with an interesting technical point of view, allows the latch with one hand. Suitable for complete products in various sectors of the economy in the production of theatrical scenery, furniture manufacture, production appliances, and many others. The products are made with a loop for a padlock and a friction screw adjustment. Latches welded (series 100-500) – this type of impact-resistant latches, with a large load capacity and durability. Suitable for complete products in various sectors of the economy. In their production of welded components used, which eliminates the possibility of internal stress and lends structural strength.
Materials used. All latches and locks are made from high quality materials, specially designed for a wide range of applications, even in the harmful environment. Used for the production and cold hot-rolled steel, stainless steel AISI 316. Latches and locks are zinc coating thickness of 12 microns, with the exception of products without mounting holes, designed for welding. Also available are special options for coverage, such as yellow, green or black chrome. Also applied powder coating clips in various colors.
