In order to ensure safe lifting of loads, static stability of mobile cranes is very important. The limit load capacity refers to the maximum weight, which can be applied to a mobile crane before it tilts over. This capacity depends on dimensions, own weight, length, and hand position, and from the position and length of supporting (stabilization) legs. The maximum (limit) tension for the weakest bearing element is also important in terms of limit load capacity of mobile crane, whereas it is also important to observe ground-bearing capacity. The article also discusses theoretical and experimental analysis of the limit load capacity of a mobile crane for different working conditions. Analysis results for some most typical examples are shown on a graph, which also shows the calculated load capacities and load capacities prescribed by the mobile crane manufacturer. This provides a mobile crane operator with a quick response to extreme (limit) abilities of lifting loads. Proper awareness of limitations regarding machine abilities contributes to confident and safe reactions in critical moments of decision.
