PE "OCC" appeared on the Ukrainian market of mechanical connection of rubber conveyor belts in 2006 and immediately proved itself as a reliable supplier of high-quality goods. Implementation connectors belts PWS in Ukraine - is the main activity of the organization. In a very short period of work in this field of activity of our company acquired a wealth of experience in the promotion of products, we are exporting products adequately presented and proved to be exclusively on the positive side. Beginning with 2013 PE "OCC" was organized on the basis of enterprise PPTE "Goleol" production of high mechanical connectors PWS fabric belts for conveyors and their further successful commercial implementation. We are the only manufacturer of such products in Ukraine. All mechanical connectors PWS have high rates of strength and reliability. High strength mechanical fasteners of rubber conveyor belts (60% of the strength of the tape) was established as a result of full-length sample test joints of conveyor belts using connectors PWS, which were held at the State Makeevka Research Institute for safety in the mining industry. High reliability mechanical connectors of rubber conveyor belts using connectors PWS confirmed by operation of heavy-duty conveyors for coal mines and ore-dressing and processing enterprises of Ukraine. These characteristics of mechanical joints when using PWS connectors are achieved through the use of modern technology steel and high-quality materials. Manual docking of rubber conveyor belts 10 mm thick or more and a strength of 500 - 1600 kN / m is an alternative way with respect to the docking of the belt ends by hot vulcanization and bonding. Manual docking is indispensable when using a conveyor delivery of coal, ore, rock mining, as it has the following advantages compared to hot curing and gluing the ends of the tape: - Manual docking connector using PWS produced in minimal time, which is several times less than the time required for alternative methods of joining, is especially important when carrying out repairs; - Does not require a special environment for the execution of works on docking and is not associated with the release of hazardous substances into the environment; - Manual docking of the least expensive cost compared to using alternative methods for reducing the fuel dock on the tape; - In conjunction with PVA compound is carried out qualitatively, the material does not destroy scrapers, cleaners, and damage to the main rollers, tension and drive drums at all possible.
