Recently, World Heavy Industry's W2900 hydraulic excavator successfully rolled off the production line. This model is a large crawler-type hydraulic excavator independently developed by World Heavy Industry. The successful development of the 90T excavator has further expanded World Heavy Industry's product line and marks another step forward in the company's R&D capabilities for excavators toward the high-end and large-scale fields.

　　The development of the World Heavy Industry W2900 crawler-type hydraulic excavator features ten major innovations:

　　1. Automatic two-speed travel mode;

　　2. Adoption of a high-performance environmentally friendly engine that meets European and American standards with low exhaust emissions;

　　3. Adoption of a two-stage dual air filter with a blockage indicator;

　　4. A rear-view camera and a large color LCD monitor provide an unobstructed rear view, thereby improving safety during machine slewing and backward travel;

　　5. The slewing system and working equipment are equipped with self-lubricating devices;

　　6. The entire machine is equipped with dual systems of automatic centralized lubrication and manual lubrication. The automatic centralized lubrication system can automatically supply oil to each lubrication point according to a preset program, facilitating routine maintenance; even if the automatic centralized lubrication system fails, the lubrication points can still be lubricated through the manual lubrication system;

　　7. The entire machine is equipped with a fuel refueling pump, making fuel filling during operation convenient;

　　8. For the first time, a hydraulic oil quality sensor is introduced, which can monitor important parameters such as hydraulic oil viscosity, density, dielectric constant, and temperature in real time, enabling timely understanding of the hydraulic oil condition at different stages of machine operation;

　　9. A 24V-12V DC power converter is introduced to provide users with a 12V power supply for convenient use of in-vehicle devices such as mobile phones and MP3 players;

　　10. A standard-equipped swing alarm buzzer with audible and visual alarm functions is provided, and the control mode can be set by the user according to actual conditions.

　　World Heavy Industry's 90-ton crawler-type hydraulic excavator will deliver more outstanding motion performance, economic performance, and comfort, providing powerful support for large-scale engineering projects such as mining and hydropower.
