Product catalog summary
Specifications
The MIDI-EXCAVATOR is powered by a Komatsu SAA4D95LE-7 engine, delivering 72.6 kW / 97.3 HP at 2,050 rpm. It has an operating weight between 12,880 and 13,900 kg and a bucket capacity of 0.40 m³. The hydraulic system includes a HydrauMind closed-centre system with load sensing and pressure compensation, providing a maximum flow of 229 l/min.
Versatility and Performance
The excavator features a compact design with 4-wheel steering and three steering modes for enhanced mobility. It includes a two-piece boom, standard hammer line, and a second auxiliary circuit, powered by an EU Stage IV engine and Komatsu’s CLSS hydraulic system for high productivity.
Environmental and Fuel Efficiency
The EU Stage IV engine is eco-friendly, with adjustable idle shutdown and fuel-saving technology, reducing fuel consumption by up to 6%. The engine management system ensures precision, while the viscous fan-clutch reduces power loss and noise.
Comfort and Safety
The cab is ergonomic with a widescreen monitor and joystick control for auxiliary circuits. Safety features include ROPS and OPG compliance, KomVision surround view, and a neutral position detection system, enhancing operator protection.
Maintenance and Monitoring
Maintenance is simplified with an electric refueling pump and accessible service points. The Komatsu Wireless Monitoring System (KOMTRAX) offers real-time data for proactive maintenance, reducing costs and improving performance.
Additional Features
The excavator offers six working modes for optimized power and fuel use, excellent travel performance, and high lift capacity. Its design allows safe operation in confined areas, with a short tail swing and KomVision for better visibility.
