Hitachi ZX690LCH-5A: work well advanced and reliable
Hitachi built machine 5A series excavator ZX690LCH-5A new mine excavator equipped with in line with national III emission Isuzu engine, super power it can achieve 345kW, and with foreign ton mine machine compared with the power advantage is more prominent, and with a large rock 4 big output operation can be realized efficiently.
The three stage of new environmental protection Isuzu engine increases the cylinder suction capacity, fuel efficiency will be further improved. The high pressure common rail fuel injection, the high-pressure fuel savings is uniformly supplied each fuel injection device, to optimize the control of combustion, through the realization of complete combustion, to reduce emissions of black smoke, exhaust cleaner.
The hydraulic system model HIOS III -B is Hitachi built machine for large-scale environmental excavators tailored by optimizing the original large hydraulic system and. Through the improvement of hydraulic pipeline and software, hydraulic loss is reduced, operation performance is enhanced, and the working efficiency of ZX690LCH-5A excavator is enhanced.
For large mine excavators, the durability of their structural parts is particularly important, otherwise it will be difficult to cope with long-term harsh conditions. The front end of the working device of mine excavator using Hitachi ZX690LCH-5A is very solid, durable boom and arm, internal weld (H) enhanced, can not stop working in the mines and quarries to poor working site best play a role.
The durability of the ZX690LCH-5A excavator is also highlighted in the enhanced upper slewing platform and the lower body. For the new ZAXIS platform, a 30% - section steel plate with an outer edge of the D - shaped cross section is used to enhance durability. The new ZAXIS-5A retains the reliable lower running body structure of the 3G model, and strengthens the handling of the box structure and the position of the reinforcing plate of the tensioning wheel to improve the walking stability. An enhanced two stage side ladder is also provided to facilitate driving up and down the cab.
To improve the durability of the engine, a fuel filter and two standard oil and water separators are added to the fuel system. At the same time, in order to increase fuel air emissions, the fuel system has been added to the electromagnetic pump. To prevent air from entering the cooling circuit, the auxiliary water tank is equipped.
Hitachi ZX690LCH-5A mine excavator cab configuration of high strength, in accordance with the 2 standard OPG with the top door. According to the characteristics of night work for large excavators at night, the movable arm and right lamp are designed for the 690 standard to ensure the safety of night work.
Hitachi's E-Service system, the preventive maintenance management work of the machine into the electronic information age. Hitachi built with the client machine can share information, to determine whether the need for inspection and maintenance of machines. When the exception occurs, the alarm information can also be used to diagnose the cause, which helps the customer to monitor, manage and improve the output rate, maximize the customer's benefits and reduce the failure time of the customer's equipment.
Hitachi global E-Service system
Hitachi ZAXIS series is a new generation of hydraulic excavator work well, productivity, reliability, durability and environmental protection and energy saving has been verified, based on the traditional Hitachi technology, the use of cutting-edge technology to achieve further work fast and large capacity operation device. Hitachi ZX690LCH-5A excavator will lower body walking environmental protection engine, advanced hydraulic system, high strength and the front end of the working device, and perfect the power and speed matching, and for the maker.
