Armed with stability and productivity

The ZX50U-3 is nimble, powerful and designed to keep their tails close to their tracks rather than bashing into fences or walls. We’ve reduced the size and footprint without sacrificing the Hitachi qualities you’ve come to expect - long life, high productivity, multifunction operations, smooth hydraulics and easy maintenance.

Product highlights

  • Reduced fuel consumption with a cleaner, more powerful Interim Tier 4 engine.
  • Efficient zero- and near-zero-tail-swing designs lower the center of gravity, increase stability and let you work in tight areas.
  • WC tungsten-carbide thermal spraying at the contact surfaces between the arm top and bucket reduces wear and jerking.  
  • Long arm/extra counterweight available. 
  • Auxiliary hydraulics are now operated with a switch conveniently positioned atop the right-hand pilot lever.
  • Automatic shifting between high and low travel speeds allows the excavator to shift into low when more power is needed, without operator intervention.
  • Optional angle blade for easier backfilling.

Tough components

The reinforced D-shaped frame is like that found on bigger members of the Zaxis family. Lubricant-impregnated HN bushings are used for greater reliability and increased service intervals. The highly durable box-section frame, enlarged counterweight and weighted undercarriage lower the center of gravity and increase stability. Rubber crawlers feature a steel core structure to protect shoe edges. Large-diameter drive sprocket and track idler increase durability and reduce the likelihood of a thrown track.

Operator comfort

You’ll love the Zaxis cab. It comes with an adjustable seat to provide day-long comfort and ergonomically correct low-effort pilot controls to enhance ease of operation. An enclosed cab option comes standard with air conditioning and heat, as well as a cloth suspension seat. And the canopy provides generous openings for easy entry and exit.

Easy to maintain

The ZX50U-3 features a side access door that is easy to open and that makes maintenance a breeze. The cabin floor can even be tilted up to 50 degrees for easy, quick servicing. Inspection points are concentrated for quick daily maintenance. The X-beam track frame is rounded for easy mud removal, while the one-sided slope on the side track frame minimizes mud packing. Split-type front hoses are jointed at the machine cover ports and the back of the boom for easy replacement.

Visibility and safety

Zaxis Compacts come standard with a TOPS/ROPS/OPG canopy. Tinted front and top windows, a one-piece door window and extra glass on the lower bottom right-hand side provide excellent visibility. 

The LCD monitor is easy to read and positioned to further improve the view from inside the cab. One quick glance is all it takes to verify that systems are normal. The monitor also features two trip meters to help track scheduled maintenance or jobsite timing.

Low operating costs

Take advantage of simple, durable and efficient components, while retaining many characteristics of our larger excavators. The reinforced D-shaped frame helps prevent impact damage along the edges. And you can count on the job-proven HN bushings on the boom, arm and bucket for reliability. These ooze oil from the pores of the bushing into the clearance between the pin and bushing to increase greasing intervals.
