As well as zero-exhaust emissions, the new unit will deliver lower noise levels, enhanced efficiency numbers, exceptional performance in confined spaces, and fewer maintenance requirements says the Japanese manufacturer. There should also be less downtime than that required by conventional models too.
The new ZX55U-6EB is said to operate with exceptional manoeuvrability in confined spaces, as it has inherited the short tail swing of the diesel-powered ZX55U-6 model. It also provides equally high levels of performance.
Hitachi hopes that customers will be able to work on a diverse range of projects with the ZX55U-6EB, including urban construction sites, residential building and waste material handling projects – wherever the environment is a priority.
Customers can choose between battery-powered operation, using 39kWh lithium-ion batteries, and wired operation, which allows the machine to work while charging from a CEE 400VAC 3-phase power source. The cab has air conditioning as standard.
The status of the electric drive system, including the battery level and motor load factor, can be monitored remotely. Reduced external sound levels (91dB) allow for greater flexibility for working times and options. Safety is enhanced by the rear camera to monitor the secure connection of the cable during wired operation.
The ZX55U-6EB shares the same concept of Hitachi’s eight-tonne ZE85 electric excavator, which was developed by EAC (European Application Center), a joint venture between Hitachi Construction Machinery Co and KTEG (Kiesel Technologie Entwicklung). Further underlining its commitments to delivering sustainable solutions, Hitachi intends to expand its battery-powered products line-up in Europe in the future.
“Hitachi is delighted to offer our customers a new battery-powered model capable of working productively and efficiently in small spaces,” said HCME president Takaharu Ikeda.
“We are working hard to meet the growing demand for zero-emission equipment and listening carefully to our customers’ requirements for improved safety, increased productivity and reduced life-cycle costs.”
