The Hitachi Mini series, including the ZX30U-5B, ZX35U-5B, ZX40U-5B, and ZX50U-5B excavators, all feature Yanmar engines. When comparing the parameters, the ZX30U-5B and ZX35U-5B are similar except for their dimensions, as they share the same engine model, power, hydraulic pump, and hydraulic flow. Similarly, the ZX40U-5B and ZX50U-5B also have identical specifications. Unlike the models introduced in the first part, these excavators come with cabins and air conditioning systems, providing a more comfortable working environment in various outdoor settings. If working indoors with height restrictions, the cabins are relatively easy to dismantle.
In addition to the eight mini excavators introduced in the first part, Hitachi offers five more UR models that will be detailed in the next part. These models are highly functional in large estates, farms, orchards, urban landscaping, and basic construction projects.
The Hitachi Mini excavators are known for their excellent short-tail design, which allows for a small turning radius. This feature is particularly useful on narrow roads, in indoor spaces, and for many basement tasks. For farms and orchards, the rubber tracks minimize damage to the ground and greenery. With various attachments, these mini excavators can efficiently handle small waterways, afforestation, road paving, building renovations, and more. The ZX55. in particular, boasts a maximum digging height of over 5 meters and a digging depth of up to 3.77 meters, capable of completing over 80% of different types of urban infrastructure projects.
In the first and second quarters of 2024. Tiedou's demand for mini excavators has soared. Besides competitive pricing, many individuals and businesses have purchased mini excavators to meet their operational needs. Hitachi’s used excavator inquiries and transactions remain highly regarded. In the first half of 2024. the transaction volume for Hitachi Mini excavators increased by 7%, with reference prices ranging from $12.000 to $19.000. While Hitachi's market share in mini excavator sales is not the highest, its significance among many users remains undiminished.
Below, Tiedou introduces the basic parameters and specifications of these four Hitachi mini excavators.
