Hitachi Construction Machinery Co., Ltd. has announced that the company will launch the Hitachi EX2000-7 ultra-large hydraulic excavator in October 2021. The EX2000-7 is remodelled from EX1900-6 and consumes up to 19 per cent less fuel while maintaining the same productivity.

EX2000-7 has high durability of structural parts achieved by the design employed on the current EX-7 series machines and it can incorporate support services for repair works and inspections based on ICT and IoT. In addition, it achieves higher fuel efficiency due to an entirely new hydraulic circuit, an addition of a work mode selection function, etc. Because of drastic cutbacks in fuel consumption, the machine contributes to reduction of environmental impact and the life-cycle cost. Since the first large hydraulic excavator UH50 (operating weight: 159 tons) was launched in 1979, ultra-large hydraulic excavators by Hitachi Construction Machinery have worked at mine sites throughout the world gaining a reputation for high productivity, reliability, durability, etc.

Hitachi has also provided solutions such as mining equipment utilizing ICT and IoT and operation control systems to address challenges faced by customers such as improvement of safety and productivity and the reduction of life-cycle costs. At an operating weight of 193 tons, the EX2000-7 is one of the smaller Hitachi EX-7 ultra-large excavators, high demand is expected from small to medium-sized mining and quarrying operations, to whom fuel efficiency is critically important. The EX20007’s impressive 19% fuel saving has been achieved through a range of new designed, energy-efficient features that have made the engine more compact while retaining outstanding productivity. When compared with its predecessor, the EX1900-6, the EX2000-7 can save as much as 460 tons of CO2 emissions per year per machine.
