Kubota is advancing in the construction industry with an innovation in electric excavator design.
Kubota first introduced its prototype 2.5 tonne electric excavator at Intermat in 2012, marking the beginning of its journey into electrification within the construction industry. Now, the company is taking another significant step forward by unveiling an electric retrofit option for the KX019 (1.8-tonne) and U27-4 (2.5-tonne) diggers. This innovative concept aims to make the transition to electric equipment more accessible and practical for the construction industry.
As global demand for sustainable alternatives grows, Kubota is addressing a key industry need: machine reusability and longevity. The new solution allows customers t replace their excavator’s standard diesel engine with a modular battery pack. Alternatively, machines can be equipped with the battery pack from new and later replaced with a diesel engine or vice versa.
Cost has always been a barrier to adopting electric machinery. But with this retrofit solution, customers gain flexibility. They can enjoy the low running costs of electric and still have the option to switch to diesel, if necessary. It’s about providing choice and easing the transition to a greener future.
Kubota’s solution also reduces maintenance costs and operating overheads. With no engine and associated components, service time and costs are significantly reduced, saving customers both time and money. In addition, electricity costs far less than fossil fuels, providing a significant economic advantage.
What’s more, the retrofit solution offers low noise levels, making it ideal for urban environments and indoor applications. Noise levels at the operator station are significantly lower than the diesel equivalent, allowing better communication and safety with colleagues. Quiet operation also allows for longer working days, maximising time on site and accelerating project schedules.
Kubota’s solution addresses the unique needs of construction operators, recognising that many machines only operate for a few hours a day, often less than two hours. The battery pack’s runtime aligns with this usage, and with the ability to top up charges throughout the day, working hours can be easily extended.
Kubota’s approach is aimed at providing an easier path to adopting electric technology without abandoning the flexibility of existing diesel setups.
The electric retrofit is expected to roll out throughout 2025.
