The ZX50U-5N compact Hitachi excavator has an operating weight of 10,560 pounds, maximum dig depth of 11 feet 7 inches, and a maximum reach of 19 feet 7 inches. The 36.3-horsepower, reduced-tailswing excavator has an independent swing boom and 360-degree rotation.

A standard quick-coupler-equipped, boom-mounted auxiliary line aids attachment hookup on the Hitachi ZX50U-5N. An auxiliary function lever (AFL) is available with an analog switch, trigger switch, and horn for running attachments such as a breaker or an attachment with swing.

Engine speed can to be matched to the job with power/economy work modes. The power mode provides higher engine speeds for most general digging work, and the economy mode reduces engine speed for lighter digging jobs. The Hitachi Triple H (HHH) hydraulic system enables combined operations by adjusting the optimal flow rate for all actuators.

Ergonomic short-throw hydraulic pilot control levers provide smooth, predictable low-effort fingertip operation, and control patterns can be quickly switched from backhoe- to excavator-style controls with a control-pattern selector located in a compartment beneath the seat.

A 3.5-inch LCD monitor keeps the operator informed of vital information while allowing fingertip control of several functions, including auto-shutdown and power/economy modes.

Oil-impregnated HN bushings are used on the boom, arm, and bucket joints. Heavy-duty X-frames and a single-pin swing post boost the structural integrity of the excavator.

The undercarriage includes rubber tracks with a unique steel core that resists cracking, and large-diameter drive sprockets and track idlers.

A V-shaped cylinder guard provides added protection to the boom cylinder. To prevent damage to the upper structure, a D-section frame skirt improves upward impact resistance by 20 percent over previous models.

A hinged door provides wide-open access to the side-by-side oil cooler and radiator core for easier cleanout. Routine checks, such as engine oil level, are quickly accomplished from ground level. A hydraulic fluid sight gauge and see-through coolant reservoir allow the operator to check at a glance.

Adjusting proper track tension only requires a grease gun and a wrench. The excavator has a large fuel tank, 500- and 2,000-hour engine and hydraulic oil service, and 500-hour greasing intervals.

The operator station tilts forward 50 degrees, providing access to the swing motor, hydraulic control valve, engine starter motor, and alternator.
