In April 2, 2018, the "China Construction machinery annual product TOP50" award ceremony was held in Beijing InterContinental Beijing Beichen Hotel. More than 200 guests from relevant ministries, associations, manufacturing enterprises and news media were invited to witness the release of the TOP50 list in 2018. In the 50 outstanding products representing the highest performance level of the industry, Hitachi construction ZH200-5A hybrid hydraulic excavator was awarded the gold medal for technological innovation. At the ceremony, Mr. Gao, who was deputy general manager of Hitachi construction machinery (Shanghai) Co., Ltd., took the award on behalf of Hitachi construction machinery.
Mr. Hitachi, deputy general manager of Hitachi construction machinery (Shanghai) Co., Ltd. came to the stage to receive the award (figure left 4).
The "annual product TOP50 of China engineering machinery", which began in 2006, is a barometer for the development of industry and the growth of enterprises. All of the products listed on the list are the models of annual R & D innovation. Hitachi construction products has been on the Top50 list for many years. Since the launch of ZAXIS-5A series, it has realized the four degree reelection of Gold Award, showing its competitive edge. Following the list of 2015, 2016 and 2017, the ZH200-5A hybrid excavator won the unanimous approval of the review team for its excellent energy saving and reliability, and won the "gold medal of technology innovation", which represents the industry's top technical strength again.
Honorary certificate of Gold Award for TOP50 technology innovation
Hitachi built ZH200-5A hybrid excavator, set Hitachi group comprehensive technical strength in one. The new TRIAS-HX system integrates the technical achievements accumulated by Hitachi in the fields of hydraulic excavator, electric excavator, and battery excavator for many years, which brings excellent hybrid power output performance, and realizes the consideration of both high output and low energy consumption. The energy saving 3 pump and 3 valve hydraulic system can reasonably distribute the output flow of 3 main pumps, so that the output control is refined, and the energy loss during shunting is reduced.
Thanks to the excellent energy saving design of the system, compared with the ZX200-5A model, ZH200-5A can reduce fuel consumption by 15% and fuel efficiency by 18% in PWR mode. Compared with ZX200-5G, the two indexes can be optimized by 25% and 33% respectively, and the quality improvement is achieved. Even when the hybrid power system is cut off, the equipment can operate normally.
In the core part, the ZH200-5A PCU inverter adopts the Hitachi frequency conversion technology with excellent performance on the Shinkansen and dump trucks. The electric parts such as the electric motor, the capacitor and the high-power cable all are made by the Hitachi technology. The connector has implemented the waterproof treatment and shielding treatment to improve the reliability under the bad environment. Durability; capacitance devices used for charging and discharging are longer and more economical and durable than Ni MH or Li ion batteries. In addition, the Hitachi construction machine has used the highly praised dynamic arm regeneration system and the mining growth system on the hydraulic excavator to provide powerful technical support for the more fast and smooth complex operation.
The ZH200-5A hybrid excavator carries the imported power of the imported ISUZU engine with the rated power (net) of 113 kW, combined with the hydraulic system of the 3 pump and 3 valves to achieve excellent basic performance. On the basis of the intensive design of the core components, the Hitachi construction machine also optimizes the fuel circuit, combined with the multi-stage fuel filter system to ensure the full performance of the generator performance.
Field construction of ZH200-5A
In addition to the new power system, ZH200-5A also has excellent competitiveness in terms of safety, comfort, maintenance and information technology. D section frame, integrated X beam, reinforced large capacity shovel and other designs ensure the durability of the product; wide field of vision and operation space, suspension seat, color multi-function monitoring module make the control convenient and easy to follow; maintenance free electronic parts and centralized design of fuel equipment, make daily maintenance more relaxed; exclusive e-Service Information system and ConSite platform are convenient for customers to share real time information with Hitachi construction machine, reduce downtime and ensure normal operation. ZH200-5A hybrid excavator has been widely praised by users since it was launched in 2016. Its advantages of low consumption, high efficiency, durability and reliability, and long term use under any working condition have been verified in practice.
Hitachi construction machinery, as the world's leading manufacturer of building equipment, has been practicing social responsibility as well as providing customers with an economical and efficient product. To achieve the "environmental vision 2025" formulated by Hitachi group (to achieve the target of CO2 emission reduction of 1 million tons in 2025), Hitachi has been committed to the development, manufacture and promotion of "electric Vask" engineering machinery products. With the introduction of a new generation of green products represented by ZH200-5A hybrid excavators, Hitachi construction will reduce the environmental load while improving the value of the product and make more effective efforts to protect the earth's environment.
