HITACHI ZX290LC-5 CRAWLER EXCAVATORS

Technical Description

The Hitachi ZX290LC-5 is a mid-sized hydraulic excavator engineered for demanding construction and earthmoving applications. Powered by an Isuzu AH-4HK1X diesel engine, this machine delivers 140 kW (187 horsepower) of rated power at 2,100 rpm, with maximum torque output of 652 Nm at 1,800 rpm. The 5.193-liter, turbocharged, water-cooled four-cylinder engine meets Stage IIIB emission standards, combining high productivity with improved fuel efficiency compared to earlier models. Operating at a working weight of 63,273 pounds (approximately 28,800-30,300 kg), the ZX290LC-5 delivers impressive digging capabilities with a maximum reach along ground of 37 feet and maximum digging depth of 25.83 feet (7.22 meters). The excavator features a variable geometry turbocharger and high-volume cooled EGR system that effectively reduces nitrous oxide emissions while maintaining operational efficiency. The machine utilizes Hitachi's proprietary TRIAS hydraulic system, which enhances productivity while reducing fuel consumption by up to 18 percent in ECO mode compared to previous generation models. The reinforced undercarriage and strengthened front attachment provide durability in harsh working conditions. A ROPS pressurized cab protects operators from dust penetration and potential tip-over incidents, while ergonomic features including an air-suspension seat, expanded legroom, and comprehensive visibility optimize operator comfort. The excavator incorporates an attachment support system with 11 modes for versatile equipment compatibility, making it adaptable for various construction tasks.
