A machine is adapted for operation powered by any one of a plurality of interchangeable power sources. The machine may include an undercarriage configured for supporting ground engagement members that propel the machine and an upper structure rotatably supported on the undercarriage. The upper structure may include a swing frame, with the swing frame supporting an operator cab, any one of the plurality of interchangeable power sources, hydraulic components, electrical components, and a counterweight disposed at a first end of the swing frame. The counterweight may include a hollowed out portion facing toward the swing frame. The hollowed out portion of the counterweight may be centrally aligned with a center core portion of the swing frame configured for supporting any one of the plurality of interchangeable power sources, with the one power source being partially accommodated within the hollowed out portion of the counterweight.

Machine configuration and control system enabling interchangeable power sources

A travelling frame of a travelling device positioned between a center frame and a travelling motor attachment portion includes an upper plate extended toward the center side of the vehicle to form an extended portion. A long hole into which travelling motor hydraulic piping is inserted is formed in the upper plate along the extended portion. The travelling motor hydraulic piping extends from a lead-out hole opened in an end plate of the center frame, through the long hole of the upper plate and a long hole opened in an end plate, and inserted into the travelling motor attachment portion.
