Cranes

If you arrange a survey on what to consider the greatest achievements of humanity, then lifting cranes are not that they will not be in the top ten, hardly anyone will remember them at all (well, it is possible only people who are professionally connected with cranes, and then not a fact). On the other hand, what can be more important in the production of an item, whether it be a house or a car, than the ability to move goods of any mass to an arbitrary place? According to the brick, the occupation is of little interest to the twentieth floor, although the pyramids were somehow built. In mechanical engineering, there are also nowhere without cranes, however, as in any other industry. And when you walk past a construction site with tower cranes, or see portal cranes in the port, is this spectacle not impressive at all? 
Cranes - devices are not easy and dangerous, the crane should be designed and calculated according to strict standards, carefully designed and tested. Drawings must be made without errors, minor inaccuracy can then be expensive during operation. Maintenance should also be taken very seriously.
The definition of a crane sounds simple - a cyclic machine designed to lift and move cargo in space. Cranes can be classified by a large number of features, such as:
design
ability to move
drive type
degree of rotation
support type
type of load-gripping element (not only hook)
design features
field of application, etc.
Our website presents drawings of these irreplaceable mechanisms and you can download them now.
