In response to concerns about energy shortages and environmental issues, Hitachi Construction Machinery has assembled Hitachi Group's comprehensive technical capabilities and launched a new hybrid excavator in order to achieve sustainable development of the society and the long-term value of customers. The new TRIAS-HX system has passed on. Hitachi Construction Machinery has developed years of accumulated experience in hydraulic excavators, electric excavators, and battery excavators. By combining a hybrid system with an energy-saving 3-pump hydraulic system, it has achieved lower fuel consumption and less emissions. The power unit product inherits Hitachi's excellent frequency conversion AC technology and manufacturing technology. Energy-saving and environmentally friendly 'TRIAS-HX system' for lower fuel consumption and emissions The new 'TRIAS-HX system' combines a hybrid system with an energy-saving 3-pump hydraulic system. Using Hitachi's impressive technical experience, it provides reliable technical support for lower fuel consumption and less emissions. Reduced fuel consumption Energy-saving and environmentally friendly 'TRIAS-HX system' for lower fuel consumption and emissions Hybrid power system The energy generated during the deceleration of the rotation is converted into electrical energy by the rotary electric motor and accumulated in the capacitor unit via the PCU. The accumulated energy is used as an auxiliary power for the acceleration of the swing and for the engine. Through the effective use of these electric energy, the fuel is realized. Reduced consumption. Energy-saving 3-pump 3-valve hydraulic system In order to improve the energy saving effect of hybrid power, we have developed an energy-saving hydraulic system. The new hydraulic system adds pumps and control valves, uses 3 pumps and 3 control valves, and achieves a reasonable distribution of the output flow of the three main pumps. Finer output control reduces energy loss during shunting and contributes to energy saving.  Efficient 'TRIAS-HX System' for excellent job performance The TRIAS-HX system, which is based on hydraulic system, adopts a new 3-pump 3-valve hydraulic system, which brings efficient operation performance through reasonable flow distribution and fine output control. 3 pump 3-valve hydraulic system for efficient operation The TRIAS-HX system uses a new, energy-saving, 3-pump, 3-valve hydraulic system. Compared with the 2-pump 2-valve hydraulic system, the pump and the control valve are used to distribute the flow rationally, reducing the need for throttling during compound operation. The shunt provides finer output control and results in more efficient operation. In addition, the highly acclaimed boom regeneration system and excavation growth system are used in the hydraulic excavator to provide faster and smoother compound work. Strong technical support.  In combination with high-power engines, excellent basic performance is achieved. Equipped with the original imported engine, rated power (net) up to 113 kW, combined with 3-pump 3-valve hydraulic system, achieving excellent basic performance. ■ Bucket's maximum digging force: 158 kN ■ The maximum digging force of the stick: 114 kN ■ Walking speed (high/low): 5.5/3.5 (km/h) The large-capacity bucket is equipped with a 0.91 m3 high-capacity bucket as standard. The combination of high-efficiency hydraulic system brings a large amount of work, and fully demonstrates its high efficiency in the field of loading and unloading.  Hitachi Group's comprehensive technology builds a reliable and durable hybrid The ZH200-5A's hybrid system uses Hitachi's superior technology and Hitachi-manufactured components, coupled with a high-quality 5A engine and structural reinforcement to ensure that the machine can operate stably for a long time. Hitachi's superior frequency conversion AC and manufacturing technology The Hitachi Group, which started as a motor, holds the world's core frequency conversion AC technology and has outstanding performance on the Shinkansen and dump trucks. The ZH200-5A's PCU uses Hitachi's inverter technology, high power transmission cables, and connectors. Hitachi Cable Co., Ltd. developed a hybrid-specific product that has been waterproofed and shielded to improve its durability in harsh environments. Capacitors have been used. They have a longer life and are more economical than NiMH or Li-ion batteries. Reliable hybrid design The TRIAS-HX system uses an electric motor to provide power assistance to the hydraulic system. Therefore, even if the hybrid system is shut off, only the hydraulic system can be used to perform normal operations. In addition, in order to achieve more stable performance, hybrid power is provided. The dedicated cooling system heats the PCU, rotary electric motors and capacitors to prevent them from aging due to overheating. Front end working device · High-durability, flat-bottomed bucket with high-performance wear-resistant plates for the bottom and side of the bucket stiffening plate, which greatly improves the durability of the bucket. · The new HN bushings are used for all front-end device pins. , Effectively improve the lubrication effect and improve the durability of the front end device. · The contact surface of the connecting part of the stick and the bucket is sprayed with WC (tungsten carbide), which helps to reduce wear and seizure. Upper slewing body and lower body · D-shaped cross-section frame is used on the car platform, which can effectively resist the impact of the outside world. · The X-beam adopts integrated welding structure, which improves the strength and stability of the off-road and enhances the durability. The tensioning wheel tensioning mechanism adopts integrated design, which can effectively prevent the tensioning wheel from sliding. Highly reliable and durable 5A engine The ZH200-5A is equipped with a 5A engine with high durability and high efficiency output. The design is sturdy and durable. It not only has an enhanced design for the core components, but also optimizes the fuel circuit, plus a multi-stage fuel filtration system to allow the engine to perform well. The advanced cooling system ensures that the engine is in good operating condition. The expansion tank improves the exhaust performance of the cooling circuit. The engine periphery is made of high-durability materials and can maintain cooling performance for a long period of time.  Easy to maintain ZH200-5A aims to save customer's time and operating costs, rationalize the layout and design of daily maintenance parts, and make use of electronic information management to make maintenance work more time-saving. Routine maintenance convenience Electronic parts such as electric motors are maintenance-free and require no special maintenance on a daily basis. The main fuel filter, fuel pre-filter, pilot filter, oil filter and electric fuel pump are centralized in the pump chamber. Fuel tank drain valve , The oil drain opening is convenient for daily draining. With the expansion tank, the cooling circuit is completely sealed and there is no need to frequently fill the coolant. The bottom of the fuel tank is provided with a large size cleaning port, which helps to keep the fuel clean, and simplifies Check the operation. Add skid plates at various places to improve the safety of maintenance. Easy cleaning around the engine The hydraulic oil cooler, radiator and intercooler are arranged side by side, simplifying the cleaning of the engine periphery. The air conditioner condenser adopts an open design to facilitate the cleaning of the radiator. The insect net is installed in the air conditioning condenser and the fuel cooler. The outside, the use of a lock-type structure, easy to disassemble and easy to clean. Radiator is equipped with a cleaning cover on the top, can be cleaned by blowing in compressed air.  Multi-function information system e-Service Owner's site By using the 'e-Service Owner's site' loaded with advanced information networks, the preventive maintenance management of the machine was introduced into the era of electronic information. Hitachi Construction Machinery shared machine information with customers and used it as an element of regular inspection and maintenance.
