1. Japanese heart: Mitsubishi S6S-DT

The defining feature of this model is the legendary Japanese Mitsubishi engine at its core.

High performance: this 6-cylinder unit boasts an impressive torque reserve — confident operation under peak loads without dropping RPMs, ensuring consistent cycle times.
Acoustic comfort: Mitsubishi engines are renowned for balanced operation and low noise — a more comfortable environment for the operator and the community during urban projects.

2. Intelligent hydraulics

Multitasking efficiency: high-capacity pumps (2 × 172 L/min) enable simultaneous operations — boom lifting, swing and arm movement — without a loss in speed.
Power Boost function: on exceptionally hard ground or heavy lifts, the system triggers a momentary 10% pressure increase for extra breakout force.

3. Absolute stability

Lifting capabilities: powerful hydraulics with a stable base (outriggers + dozer blade) let the excavator double as a crane/handler for laying concrete culverts, pipes and well rings.
