Cranes are classified as crane machines that are used in many branches of activity. These machines are used in particular on construction sites, but are also used in workplaces and for assembly, reloading and other types of activities.

Due to their design, the cranes can handle a limited space. They are made of a cone or cylinder, which determines the maximum height of the loads lifting by the machine, as well as a rotating base, which is responsible for the maximum outreach. At the end of the booms of the cranes there are tractors equipped with various types of grips adapted to the type of transported objects or materials.

When lifting loads, the most important unit is the tonometer which expresses the maximum loading moment. It is calculated by multiplying the maximum weight for a given device in tonnes by the horizontal distance in meters from the point of support of the outriggers.

The most popular type of cranes is the tower crane, which allows you to lift loads of several dozen tons, even above 100 meters. There are also port cranes used in cargo handling works. The third type of cranes are self-propelled cranes, which are self-propelled or mounted on cars.

To operate the presented machines you need a course for a crane operator Tower cranes and passing an examination before a committee of the Office of Technical Inspection. This confers the crane licence needed to work as an operator.
