Hitachi Zaxis-5 Excavators Built for Productivity, Reduced Operating Cost

The Zaxis-5 Series developed by the Design Centre at Hitachi Construction Machinery Co., Ltd. (HCM) in Japan, are built for productivity, durability and reduced operating cost, according to the company.

Yusuke Kajita, general manager of HCM's Construction Equipment Development Centre, is responsible for the team of 200 engineers behind the new medium-sized excavators. “We develop new machines, concepts and specifications in accordance with customer and market requirements,” said Kajita. “For example, the Zaxis-5 has better fuel efficiency, lower noise levels and excellent comfort.”

The new ZX160LC-5 replaces the ZX160LC-3, and the ZX210-5 and ZX210LC-5 replace the ZX200LC-3 – all introduced in 2007. The ZX210LC-5’s undercarriage is 12-in. longer than the 210 and supports a greater lifting capacity. The Isuzu AI-4JJ1 engine used in the ZX160LC-5 generates 90 kW (121 hp); the ZX210-5 and 210LC-5’s Isuzu 4HK1 engine generates 119 kW (159 hp).

The powerful Isuzu diesel engines employ a cooled exhaust gas-recirculation (EGR) platform paired with a diesel particulate filter (DPF) to meet EPA IT4/EU Stage IIIB emissions regulations. These easy-to-maintain engines require no special additional fluids – just ultra-low-sulfur diesel fuel and CJ-4 engine oil. The DPF is replaced at 4,500 hours by a Hitachi dealer.

Three work modes allow an operator to choose a digging style that fits the job. High Productivity (HP) delivers more power and faster hydraulic response. Power (P) delivers a balance of power, speed and fuel economy for normal operation. And Economy (E) maximizes fuel efficiency while delivering an enhanced level of productivity.
