It is the fundamental concept of the spreader beam, a mechanical structure that separates two legs of a sling, grommet or chain, all of which could only work at a straight tension and converts them into two suspended elements separated by a certain length and they spread the load between them. In the tables capacity of a Spreader Beam in our catalog (available for download at the bottom) are developed three typical work configurations: 20, 30 and 45º. Considering the angle that forms the top slings with the vertical one (In case of having the complementary angle it is only necessary to subtract it from 90º to have it). The tables are valid for any value equal to or less than the said angle with the vertical. The choice between one or another configuration capacity of a Spreader Beam will be due to the height available under hook and considering the length of the entire set of lifting accessories, the height of the load itself and the obstacles and height to be overcome. On the other hand, it is necessary to consider that the configurations that lose more height are more slender and have a more contained weight. On the other hand, configurations that lose less height are more robust and heavy, which may limit the operation due to the available crane capacity, apart from being more expensive. Therefore we have a wide range of options capacity of a Spreader Beam to accommodate the product to each application.
