The Hitachi ZX60USB-3 is a new ultra-short excavator with a swing boom and backfill blade, and it is designed for jobs along walls, guard rails, narrow roads and tight work sites. The independent swing boom moves 80 degrees to the left and 60 degrees to the right. The boom offset is 33.5 inches to the right and 28 inches to the left. The unit is available with either rubber or steel tracks. A 6-foot, 1-inch-long arm with an additional 573-pound counterweight is also an option. Just like the larger models in the Zaxis series, the ZX60USB-3 uses a D-section frame skirt to increase the rigidity of the upper structure frame. A box-section stay is used at the blade for greater durability. The one-piece swing post helps reduce jerking of the swing boom. WC tungsten-carbide thermal spraying at the contact surfaces between the arm top and bucket reduces wear and jerking. The radiator and oil cooler are arranged in parallel for easier and quicker cleaning. Waved fins and radiator front net help reduce dirt clogs.
