Hitachi Construction and Mining Co., Moline, Ill., has introduced the ZX75US-3 excavator. The standard weight of the machine is 17,743 pounds and has a maximum swing speed of 10.5 rpm. The ZX75US-3 can handle bucket attachments ranging in size from 0.40 to 0.66 cubic yards. The new shape of the backfill blade provides better crowding performance and additional machine stability. The swing boom enables parallel digging to walls, guard rails and foundations. The ZX75US contains the turbo-charged Isuzu 4LE2X engine and Hitachi’s patented HIOS III hydraulic system. Cab features a suspension cloth seat, controls, multilingual LCD monitor, slide-open front glass and tinted, transparent roof hatch. Two engine modes can be selected to match engine rpm to the operating conditions and application. The E (economy) mode for light-duty work and the P (standard) mode controls the engine speed from slow idle to fast idle.
