HITACHI ZX70-3 CRAWLER EXCAVATOR

Technical Description

The Hitachi ZX70-3 is a compact hydraulic excavator engineered for versatile construction and demolition applications. Powered by a 4-cylinder AU-4LE2X engine producing 54.4 hp at 2000 rpm, this machine delivers efficient performance in confined work environments. The excavator features a sophisticated hydraulic system with a pump flow capacity of 38.1 gpm and relief valve pressure of 3843.6 psi, enabling responsive bucket control and consistent digging power. With a maximum digging depth of 13.7 feet and maximum reach along ground of 20.3 feet, the ZX70-3 accommodates both standard excavation and precision work. The reference bucket capacity of 0.4 cubic yards suits light to medium material handling tasks. Operating at a gross weight of 15,432 pounds, the machine maintains excellent mobility with a maximum travel speed of 3.3 mph, while its compact track configuration—featuring 17.8-inch shoes and 7.7-foot width—provides exceptional maneuverability in restricted job sites. The design incorporates a minimal tail swing radius of 5.8 feet, crucial for working adjacent to obstacles. Advanced features include a widescreen color LCD monitor for operator convenience, rear-view camera option, theft deterrent system, and multi-language selection capabilities. The E-mode hydraulic system reduces fuel consumption by up to 12 percent compared to previous models while maintaining comparable production rates. Enhanced structural rigidity derives from reinforced D-section frame skirts and strengthened boom foot mounting brackets, ensuring durability in demanding conditions.
