Önhajtású

Önhajtású is a Hungarian adjective meaning self-propelled or having its own propulsion. It is used to describe devices or vehicles capable of moving under their own power without being towed or driven by an external power source. The term appears across technical, military, and industrial contexts to distinguish self-propelled equipment from equipment that requires external propulsion.

Etymology and usage notes: the word is formed from ön- (self) and hajtás (propulsion) with the adjectival suffix -ú. In Hungarian technical language, önhajtású typically precedes the noun it modifies, for example önhajtású jármű (self-propelled vehicle) or önhajtású eszköz (self-propelled device). It is sometimes used alongside related terms such as önjáró, which can be translated as self-moving or self-propelled, depending on context.

Contexts and examples: in military contexts, önhajtású describes platforms that carry weapons or sensor systems on a single chassis, enabling independent movement and rapid redeployment. In civilian and industrial contexts, the term applies to machines with an integrated engine, such as self-propelled cranes or excavators, distinguishing them from trailer-mounted or towed equipment.
