LiuGong Machinery, a premier global construction equipment manufacturer, will unveil its largest excavator to date, the 970E, at stand E551 at this year’s BICES trade show.
The LiuGong 970E hydraulic excavator was a completely new development project in line with LiuGong’s overall plan of excavator products and in accordance with market demands, ideally suited to large scale quarrying and mining operations. Built with latest component technologies and many advanced processes and developed with LiuGong’s product development process (LDP) and PLM tools, the 970E delivers a customer focused, high quality 70-ton excavator.
Advanced engineering tools, such as non-linear and linear finite element analysis (FEA), computational fluid dynamics (CFD) and dynamic simulation models were used to develop the 970E into an optimized, integrated design, all of which leads to increased reliability. The 970E features world-class components and Cummins QSX15 engine and the latest Kawasaki hydraulic components to maximize efficiency. The 970E features LiuGong’s new-generation electronic controller which is specially optimized for 970E to ensure the engine and hydraulics are matched exactly to the application for lowest fuel consumption. LiuGong used finite element analysis technology and dynamic simulations to carry out fatigue analysis to all major structural parts of 970E including operating device, slewing platform, moving frame and bucket. Analysis results were then verified in the test field using strain gage technology to ensure high durability. In addition, the 970E features centralized lubrication which extends its lifecycle. Its diesel particulate filter and air cleaner are well placed for easy access.
The 970E extended LiuGong’s product line and demonstrates LiuGong’s technical capability in designing and manufacturing large-tonnage machines. Along with other large-tonnage products like the 888 and 899 wheel loaders, the Dressta TD40E bulldozer and large mining dump trucks, LiuGong now provides a comprehensive solution to large-scale mining, quarrying and construction customers.
