Before starting the lifting work of truck cranes, it is necessary to identify hazardous areas within which dangerous factors are constantly acting or may be acting.

The boundaries of hazardous zones are determined by the places over which the cargo moves, the height of the rise and possible fall of the cargo, the radius of the departure of the cargo when it falls. It is also important to take into account the change in the boundaries of the zone if there are overhead power lines at the work site.

The image shows the calculations for identifying hazardous areas.
