Grove RT38 and 7 related models: rough terrain crane

History and service record of RT38 and 7 related models

Grove rough terrain line. Grove's rough terrain cranes trace to the world's first slewing rough terrain crane in 1968; Grove itself dates to 1947, when brothers Dwight and John Grove and Wayne Nicarry began in a rented garage in Shady Grove, Pennsylvania. Manitowoc Cranes, Wikipedia.
RT38. Manitowoc lists the Grove RT38 rough terrain crane as a non-current product; Grove's RT-58 of 1960 to 1978 sits earlier in the same rough-terrain family. GROVE RT38, Manitowoc; Looking back at the first Grove crane, Crane & Transport Briefing.
Production in Italy. Manitowoc moved Grove rough-terrain crane production to Italy to be closer to customers. Closer to the customer, Manitowoc Looking Up (archived copy).
