This is a serious contender for the heavyweight title with each machine having different boom and stick configurations. The reach boom machine has 17.5m reach but maintains a standard CAT 385 bucket size. Long reach options allow 21.5m reach with large bucket size (up to 3m3) right up to 32m reach depending on the work application. Fitted with factory hydraulics for hammer shear rotate (HSR) auxiliary circuits, the CAT385 is an impressive piece of equipment. With the newer CAT engine developments the CAT 390 offers the additional benefits of the very latest fuel effiencies and emissions technology.
