Caterpillar (CAT) bouwt al tien jaar lang minigraafmachines en verkocht in 2008 het 100.000e exemplaar. Minigraafmachines zijn erg belangrijk voor Caterpillar, dat de machines produceert in Japan en in Desford, Engeland. De machines kunnen vanwege hun beperkte omvang op plaatsen komen waar normale graafmachines niet kunnen komen. Verschillende dieselmotoren van Mitsubishi zijn zeer geschikt voor deze minigraafmachines, waaronder de dieselmotor L3E, S3Q2, K4E-D31NSA, S6S en S4L2-Y263KL.
Caterpillar beschikt over een groot assortiment rupsladers voor de bouwmaterieelsector. De Caterpillar 939C is de kleinste rupslader van Caterpillar, van 90 pk. Het heeft een laadvermogen van iets meer dan 1m3. De machine is te bedienen met slechts een joystick, die de kracht perfect overbrengt naar beide rupsbanden. De Mitsubishi-dieselmotor S6S-DT is uitermate geschikt voor de 939C.
