Technical Description

The Hitachi EX1100 is a heavy-duty hydraulic excavator designed for large-scale construction and mining operations. It features a powerful Cummins KTTA19-C turbocharged diesel engine with a displacement of 1153.4 cubic inches (19 liters) delivering a gross power output of 630.3 hp (470 kW). This engine is well known for its reliability and efficiency in demanding environments. The machine's operating specifications include a fuel capacity of 317.1 gallons and a hydraulic pump flow capacity of 129.5 gpm, enabling strong hydraulic performance for efficient digging and loading tasks. Dimensionally, the EX1100 has a shipping height of 14.9 ft, shipping length of 52.7 ft, a ground clearance of 3.5 ft, a cab height of 14.9 ft, and an overall width of 15.1 ft. The track length on the ground is 52.7 ft with a tail swing radius of 15.6 ft, providing stability and maneuverability on site. It offers a maximum cutting height of 44.8 ft, a max digging depth of 30.5 ft, and a max vertical wall digging depth of 22.4 ft, with a maximum ground reach of 49.3 ft, supporting deep and extended excavations. The undercarriage exerts a ground pressure of 103 psi and allows a maximum travel speed of 2.3 mph (3 kph). Its swing mechanism operates at a speed of 5.8 rpm to efficiently position the boom and stick. This unit’s combination of robust engine power, substantial hydraulic capacity, large dimension footprint, and powerful digging capabilities makes it ideal for heavy excavation projects requiring exceptional reach, depth, and load handling.
