  • Understanding Excavator Boom Configurations - The Scoop

    Mar 27, 2020 · For example, the long-reach version of the Volvo EC380 excavator is 27′ 11″ (8.5 m) compared to the 21′ 2″ (6.45 m) standard boom and 16′ 5″ (5 m) arm that provide a max reach of 48′ 5″ (14.75 m). This brings up a good reminder on machine nomenclature. The "L" in EC380EL means it has a long undercarriage — the "LR" in
