blog about Komatsu Unveils 35ton Zerotail Swing Mini Excavator for Tight Spaces

The zero-tail-swing design represents a breakthrough in spatial efficiency. Unlike conventional excavators, this model's rear section doesn't extend beyond its tracks during operation. This innovative feature eliminates collision risks when working near walls, obstacles, or in densely populated urban environments—from crowded city streets to indoor renovation projects.

Don't let its compact dimensions deceive you—this excavator delivers remarkable power. The advanced hydraulic system generates 35 kN of bucket digging force, capable of handling various soil conditions and materials. With a maximum digging depth of 3.17 meters and unloading height reaching 3.41 meters, it competes with larger machines while maintaining superior accessibility.

Engineered for comfort and efficiency, the cabin features intuitive controls including ergonomic joysticks and a multifunction display. The integrated HVAC system maintains optimal temperatures year-round, while the ISO/SAE convertible valves accommodate different operator preferences. The hydraulic quick coupler system enables rapid attachment changes, significantly reducing downtime between tasks.

At its core lies the Yanmar 3TNV88 diesel engine, delivering 18.2 kW (24.4 hp) of consistent power with exceptional fuel efficiency. The 9.68-gallon fuel capacity supports extended operation periods, minimizing refueling interruptions. Built with high-strength materials and precision engineering, this machine withstands demanding job site conditions while maintaining operational reliability.
