Load-lifting building – это сердце любого крана и в перечне подъемной technology, it takes a special place. Nowadays in the Russian market one can find a wide variety of hoists from different countries of the world (mainly Bulgaria, Russia and China) and different carrying capacity (the most popular lifting mechanisms with a lifting capacity of 3 and 5 tons). In order to correctly choose the hoists, it is important to imagine for which purposes you need a lift (and also to know approximately its technical characteristics). The main characteristics, which should be based on choosing a telfer - this is its payload and the height of the load. And now we list the secondary characteristics, which are also important for the acquisition of the telpher - the operating mode, the speed of lifting the load, the linear size of the telpher in height and the beam width for which it will be installed.
All types of hoists can be roughly divided into twogroups - manual and electric. Manual (or mechanical) designed for easy operation, where there is no need for operational efficiency. Plus, the manual hoist consists of not being able to supply power for its operation, since it is driven by the physical strength of the worker. Electric hoists, in turn, are divided into rope and chain hoists. The most demanded in the production of hoists - it's electric rope mobile lifting equipment, installed I-beam crane-beam. The maximum lifting capacity of such hoists reaches 50 tons. It is worth noting that manual hoists differ from electric ones by a lower and affordable price. Therefore, if you have a small production, and the lifting of the load is required on a case-by-case basis, the manual hoist will be the most reasonable choice.
In many cases, the choice falls on manual hoists and onit has three reasons (small dimensions and weight, serious load-carrying capacity (up to 10 tons), the ability to work in the absence of an electric current). Very often manual hoists are used for the installation of heavier electric hoists. Modern Bulgarian hand hoists are distinguished by high quality of manufacture and quality of operation.
Рассмотрим канатные и цепные тельферы.In the first, the lifting element is a lifting cable (which is wound on a drum), and in the second, a particularly strong steel calibrated chain (which rotates by means of a gear). In bridge and gantry cranes, most often cable rope hoists are used, and chain hoists install chain hoists (a small weight of the chain hoist facilitates its installation). After reading the review, you can be aware of the lifting equipment, but the final decision is better taken with the manager of the lifting company.
