Type 12 excavator（side swing）
* Originally imported engine. The engine conforms to China-III emission regulation and features strong power, low fuel consumption, and prominent performance and the aluminum
paralleling radiator features good heat dissipation performance.
* Originally imported hydraulic system. The four-pump constant power control mode is adopted to realize the perfect matching between hydraulic system and engine, reduce the fuel
consumption, and improve the efficiency and the double-pump confluence technology is applied for the boom and arm to realize high motion speeds and stable and efficient operations.
* Electro-mechanically integrated intelligent electronic control system with proprietary intellectual property rights. The multi-functional LCD display can realize the data acquisition and
transmission, orientation, control, protection, and remote firmware upgrade and achieve high intelligent control.
* All-new cab with broader vision field and more reasonable space layout. The air-cushioned seats and the ergonomic control system realize simpler and more comfortable operations and
minimize the driver’s fatigue.
* High reliability traveling mechanism and working device. The application of strength calculation, finite element analysis, and new structures and new materials for the structural parts
improves the reliability of the structural parts.
* Convenient repairs and maintenances. The application of full-opening front and rear hoods and side gates and the central lubrication system for slewing system realizes convenient and
efficient maintenances and reduces the maintenance costs.
