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

Oct 07, 2021 · Boom or lift-regeneration is used for lifting functions, such as the boom of the excavator. In this function, the weight force is used during lowering and the oil flow from the return of the lifting cylinder is partially diverted to the opposite side. In this way, the flow required here is already provided largely without pumping.
