Cubans remember the years of close and successful cooperation with the Soviet Union. And if middle-aged people sometimes call us out of habit “sovetikos”, the young people of all Russians calling it as “rusos. Cuba imported from the Soviet Union more than 700 items of goods (about 80% of turnover). With the assistance of the Soviet Union, the island was built more than 100 large industrial enterprises, hundreds of medium and small. Huge number of people older study Russian language in schools and universities on the island, hundreds of thousands of Cubans have studied or interned with us.
And after a bilateral contacts in 2008 are all talking about the “new phase”, “revival Russian-Cuban relations. ” The most breakthrough began in October and November. On October 17 in Havana began Russian Days in Latin America, and October 19, Metropolitan Kirill of Smolensk and Kaliningrad (now Patriarch ROC) consecrated built in the heart of Havana’s Russian Cathedral of Our Lady of Kazan. Then, at the end of the next visit of Igor Sechin, was signed nine agreements. Almost simultaneously with these negotiations, Foreign Minister Felipe Perez Roque Moscow for talks with his Russian counterpart, Sergei Lavrov, was accepted by Prime Minister Vladimir Putin and President Dmitry Medvedev. November 27 flew to Cuba, President Dmitry Medvedev, who finished in Havana, his 6 day tour of Latin America. Dmitry Medvedev and Raul Castro held talks hour and a half in ‘one on one. ” The main themes were the issues of cooperation in hydrocarbon production and processing, and nickel.
In any case the construction of one of the most pressing issues is the nuance of cargo handling. And used in the construction types of materials and equipment – all that requires not just a trigger manually force the masters, but and mechanical devices. It is hard to imagine even imagine the extent practicable at the moment to hire a regular crane. If we compare with the classical construction cranes, whose transportation and installation of the power switch to big problem, not remembering nothing of the board. In turn, the order of the crane, easy to navigate and nekrupnogabaritnogo makes it possible to rapidly solve emerging problems in the degree requirements.
In addition, for truck crane did not appear the need to mount the rails and carry out ancillary work on planning for field work. Truck crane operates in all conditions, and thus provides a reliable work with the object. At present, rental truck – it's actually a quality assistance to small businesses that operate in the construction of buildings. But even for ordinary home owners, who staged refurbishment or upgrading your home or personal problem, the possibility of truck crane will be particularly useful. A large number of companies that offer to the market segments of different vehicles, including and cranes, supply special equipment for a variety of implementation options. Dissimilar load capacity and maneuverability of different options provide an opportunity for each customer to find directly the technique, which optimal path can be established to carry out its task. Besides hiring crane – hence, to invite the same time and qualified crane operator, who has decent experience and is capable of the most significant capacity to implement all kinds of work, without exception, moreover, regardless of the degree of convenience of a cargo.
With the use of special truck crane will be the ability to move at the same time the most large building structures, as well as complicated and expensive equipment. Not counting the service crane would be extremely the way in any construction procedures: for connecting slabs or large-scale construction materials. A regularly collaborating clients, however in a position to become engaged in building the organization, always get the ability to get the discount. In addition, except for cranes and other special vehicles, companies and independent entrepreneurs always have the opportunity to rent in addition to and other vehicles – trucks, vans, flatbed car, plus a special transport for the transportation staff directly to the construction site. Saving time and functionality of the order of several vehicles at once – is a noticeable benefit.
Butt joint is a weld of two elements located in the same plane and adjacent to one another end surface. It is most common in welded structures, because has several advantages over other types of connections. Symbols of butt joints: ci – C48. Lap-joint is a weld, which combines elements are arranged in parallel and overlap. Symbols: HI-H9. Mechanical connection – a compound in which the side surfaces of the elements adjacent to each other. Symbols in the standard yet.
Gusset lateral surface of one element is adjacent a corner scrap and welded onto the end face of another element. Typically, the angle between the elements of the line. Symbols T-joints: T1-T8. Depending on the types of welded joints distinguish butt and fillet welds. Seams of the first type operates in welding butt joints, the joints of the second kind – when welding angle, tee and nahlestoch-like compounds. The shape of the cross-section welds subdivided into standard, convex and concave.
On the number of layers of welded joints can be single-layered and layered. Layer – is part of the weld metal, which consists of one or more rollers located on the one level, the cross-sectional weld. Roller – a metal joint, weld, or remelted in a single pass. In accordance with gost 2601 – 84 basic parameters form a butt joint: e – width of joint, q – the convexity of the seam, m – weld concavity, h – depth of penetration (penetration), for fillet welds – the value of leg A '(Figure 1.11). Part of the weld, the most distant from his face, called the root of the weld.
