Mining equipment

Mining equipment is, as a rule, high technologies that are necessary for work at the relevant enterprises. This equipment must be of high quality, productive and advanced. In our modern world, such mining equipment is very valuable. After all, only it can create the security of many large enterprises in need of it.

The best mining equipment that perfectly meets all quality standards. It must be reliable and durable. In addition, it is absolutely resistant to aggressive environments.

Well, if the circuit round-link are made by electric contact resistance or reflow. Such chains can be with one or two welded joints. Round-link chains calibers up to 8 mm must be manufactured long segments 50-54 m and caliber should not be less than 8 mm, but more – a length of 25-27 m. If the consumer agrees, it is possible to produce chains of other lengths. After welding, the circuits must be subjected to heat treatment according to the manufacturer’s technology. On the surface of the links in any case should not be cracks, various hairs and bundles. Round-link chains can be used as a traction or cargo body of lifting mechanisms. Depending on what field of application they are needed, short or long chains can be used.

Scraper chains are also very important. As a rule, they are manufactured for different configurations of screens and special requirements for conveyors. The set of one section of such a chain can include 3 pairs of selected segments of high-strength chains, 3 scrapers and 6 links of connecting type 2.

The screws required for the Assembly of the scraper chain, produce technology, which in any case guarantees consistently high quality. Even if the landing of the bolt head occurs in a hot state, it eliminates the appearance of hidden cracks. Due to the subsequent machining with thread rolling and heat treatment, the bolt becomes more reliable in operation for the entire life of the conveyor.

As for the nut itself, it is made of high-strength steel. The plastic insert securely fixes it to the bolt thread. Samopromzvolny loosening the nuts are excluded.

Such mining equipment as arch support is also useful for many works. This is the so-called frame support, which consists of separate fortified arches, which are installed perpendicular to the longitudinal axis of the mine workings at a certain distance from one another.

What is their purpose? They are needed in order to fix horizontal and inclined mine workings, even with a small heaving of soil rocks. The arch of rigid arch support is made of I-beams or rails. It includes two curved elements, which are rigidly connected at the top of the arch with the help of bars and bolts. Strap, flat (of flat iron) or curly (cast or stamped), make the loading more on the shelves I-beams and these protect the bolts from shear.

In other countries, arch supports use pliable, pivotable and rigid. In mounting the arches are pliable nodes and connections with the use of clamps, polycab with threads and straps. These produce a lining with V-compliant nodes.

The support is used in the coal industry to fasten horizontal and inclined workings of different service life and purpose, and in combination with other types of fasteners in accordance with the requirements. The cross section of the arch support is made, taking into account the requirements of the customer. Even the production of fasteners can be done according to customer drawings.
