Abstract: A space frame (12) for a machine (10) is disclosed. The space frame may have a first end (42) configured to be connected to front wheels (14) of the machine. The space frame may also have a second end (44) configured to be connected to rear wheels (16) of the machine. Further, the space frame may have primary structural members (56) arranged substantially lengthwise between the first end and the second end. In addition, the space frame may have secondary structural members (58) connected between the primary structural members to form substantially triangulated structures (60, 62) allowing the space frame to support a payload to empty vehicle weight ratio ranging from about 1.2:1 to 2:1.
