Hitachi Construction Machinery Co., Ltd., (president: Ryuichi Seguchi; capital: 2.219905 billion yen) has instigated a change in models from the EX27u, EX30u, EX35u, EX40u, and EX50u super-short rear-end swing radius excavators, unveiling the ZAXIS series in September and October. Specifically, the ZAXIS27U (normal bucket capacity: 0.08m3; machine mass: 2,700kg), ZAXIS30U (0.09m3; 2,980kg), and ZAXIS35U (0.11m3; 3,350kg) went on sale on the 28th of September, and the ZAXIS40U (0.14m3; 3,980kg) and ZAXIS50U (0.16m3; 4,450kg) on the 21st of October.
The U series has a noticeably slim body, and all operation systems are of the hydraulic pilot type, thus ensuring greater operability and safety. Furthermore, the right-hand side cover can now be opened and closed, allowing much easier inspection of hydraulics and greater maintainability, thereby allowing lessors, in the increasingly rental-oriented market, an unprecedented peace of mind.
This new series meets criteria set by the Japanese Ministry of Land, Infrastructure, and Transport for super low noise type construction machinery (the ZAXIS40U and ZAXIS50U are super low noise type), as well as secondary standards for nitrogen oxide and particulate matter emissions. In addition, the ZAXIS mini series is the first to feature the “e-shovel” function (satellite communication option), by which data pertaining to operation hours and position are able to be acquired.
The ZAXIS mini series is ideally suited to urban civil engineering works, such as water and plumbing work in densely populated areas. A sales target of three hundred units per month has been set.
