The Development of Construction Equipment Power Drive Components in Poland

This paper presents in its general section the history and current technological levels of designing, testing and manufacturing of basic power drive components : torque converters, transmissions and axles. The case - study section depicts the typical new product development process and sequence as exemplified by a family of axles for wheel - mounted excavators with 0.4 - 0.9 cu. m bucket capacity.

The paper presents the design objectives technical requirements and some selected results of laboratory and field tests of the axle prototypes.
