Hitachi has a range of construction equipment models, including various excavator models. The “UH” designation used to be a part of their naming convention for some of their excavators, but please note that product names and models can change over time. As of my last knowledge update in September 2021, here are a few Hitachi UH excavator models:
Hitachi UH03: This was one of the early Hitachi excavator models.
Hitachi UH07: A larger excavator model compared to the UH03, designed for heavier construction work.
Hitachi UH083: An improved version of the UH07, featuring enhanced performance and capabilities.
Hitachi UH123: Another larger excavator model designed for heavy-duty construction and excavation work.
Please keep in mind that these models may have been updated or replaced with newer ones since my last update in 2021. If you’re interested in specific Hitachi excavator models or their latest offerings, I recommend visiting the official Hitachi Construction Machinery website or contacting a Hitachi dealer for the most up-to-date information on their product lineup.
