With the increasingly stringent environmental protection requirements in the field of construction machinery, industry leaders represented by Hitachi Construction Machinery have taken the lead in making arrangements, so that products can demonstrate high-quality and sustainable competitiveness while conforming to the trend. According to the latest deployment of the Ministry of Ecology and Environment, from December 1, 2022, all non-road mobile machinery below 560KW must meet new limit requirements, including ammonia and particulate matter particle number (PM value), CO and NOX emissions, etc., and stipulates that the equipment above 37KW should be equipped with satellite navigation and precise positioning system. In response to the new policy of the industry, Hitachi Construction Machinery took active actions, relying on the advanced technology of the group, and adopted the DPF (diesel particulate post-treatment filter) technology with more than 10 years of global on-site experience. Utilizing a high-end durable ceramic filter, the technology captures particulate matter from exhaust gas and converts it into harmless CO2 emissions by increasing exhaust temperature for efficient internal combustion. The DPF system of Hitachi Construction Machinery has a simple structure, does not need to add urea solution, saves labor and worry, and has stable performance and low failure rate. It has sold more than 100,000 mainframes overseas. The engines of the 6A series fully comply with the National IV standards. While reducing emissions, they maintain the same operating efficiency as the 5A products, and add an ECO control mode to make consumption reduction and efficiency increase more intelligent.
For performance, Hitachi Construction Machinery’s new 6A product deeply optimizes the matching of the engine and hydraulic system, reduces pressure loss, improves energy utilization, and effectively improves operating efficiency and fuel efficiency. For example, the first batch of 7-ton minicomputers on the market adopts a fully electronic speed-adjustable engine, which increases the types of engine control, makes fuel injection more precise, and further improves fuel efficiency. At the same time, a new pump control solenoid valve is added to the hydraulic pump to realize speed sensing control, which improves the matching efficiency of the engine and the pump, and is conducive to stable output.
For driving experience, the 6A new machine continues Hitachi Construction Machinery’s humanized control of details, creating a more comfortable and safe operating environment in the cab. The minicomputer adopts a suspension seat, which can adjust the seat hardness according to the body weight to reduce fatigue; the lightweight handle is adopted, and the torque is reduced by about 15% compared with the previous generation product, which makes daily driving and control handy; newly added support for Bluetooth/AUX/USB external audio sources The support and practicability are close to the needs of users; the display system of the new product has also been upgraded to a liquid crystal display, which is simple and clear, and has various functions, which can help users complete multiple tasks intuitively.
Since its launch in 2014, Hitachi Construction Machinery ZAXIS-5 series products have been widely praised by the market and users. From imported core components to the self-developed HIOSⅢ hydraulic system, from high-durability components to low-cost maintenance, Hitachi Construction Machinery 5A products have been continuously listed in the TOP50 list of construction machinery and have accumulated a good reputation in the market. Now, ZAXIS-6A, which integrates better environmental protection attributes and comprehensive high-end value, is on the market. The first batch of new products on the market includes ZX70-6A, ZX75-6A, ZX520LCH-6A, and ZX900LCH-6A, which can meet the needs of customers in different industries and sizes. Use demand, its follow-up market performance is worth looking forward to.
“Safe and reliable comprehensive solutions around you” is the value concept of the new ZAXIS-6A product, and it is Hitachi Construction Machinery’s commitment to social responsibility and customer value. Hitachi Construction Machinery has always spared no effort in responding to policies and responding to needs. In line with the particularity of China’s construction machinery industry, Hitachi Construction Machinery insists on carrying out targeted localized R&D and operation, and strives to achieve the goal of “No.1 in customer satisfaction”. With the successive launch of new ZAXIS-6A products, Hitachi Construction Machinery is leading the new trend of green development and helping more customers realize their dreams on the road of promoting industry innovation.
