It weighs approximately 83,370 lbs (37,816 kg) and is designed for high productivity with a maximum cutting height of 46.5 ft, a maximum digging depth of 17.1 ft, and a maximum reach along the ground of 40 ft. The machine has a ground clearance of 2.4 ft and a height to the top of the cab of 12.2 ft, providing good maneuverability and visibility on site. The length of the track on the ground is 16.6 ft with a tail swing radius of 10.8 ft, enabling efficient operation in confined spaces. The hydraulic system includes a pump flow capacity of 115.8 gallons per minute, supporting powerful and smooth boom, stick, and bucket operation. The excavator’s hydraulic swing mechanism has a swing speed of 10.6 rpm and is supported by a swing drive fluid capacity of 2.1 gallons. It operates on a 24-volt electrical system with a 50-amp alternator. The undercarriage supports a shoe size of 28 inches and maintains a ground pressure of 9.5 psi, contributing to stability and reduced ground damage during operation. Cooling and fuel systems are sized for long operational cycles, with 6.3 gallons for cooling system fluid and a large 269-gallon fuel capacity. This combination of specifications makes the ZX250LL robust and efficient for diverse construction and excavation tasks.
