Tata Hitachi Zaxis 23 U
Pros
- Zero Tail Swing: The rear of the machine stays within the track width, making it perfect for working next to walls or in narrow lanes.
- Versatility: Equipped with a boom swing feature, allowing you to dig offset to the machine's path (useful for digging foundations along walls).
- Ease of Transport: At roughly 2.3 tons, it can be easily transported on a standard small truck or trailer.
Sona RDT-17
Pros
- At ~1.7 t operating weight, easy to transport and use in tight areas.
- Reliable engine brand commonly used in mini excavators.
- 1.8 m digging depth and ~2.7 m height are reasonable for 1.7 t machines
