Hot-selling Medium-sized Excavators
The best-selling medium-sized excavator is a high-performance and efficient machine. Its hydraulic system increases digging force by 11% and reduces fuel consumption by 8%, while the robust structure and optimized maintenance design ensure high availability and long-term, stable returns.
Product Description:
The working weight of this product is 21500 kg. Its bucket capacity ranges from 0.9 to 1.2 m³. The engine is a Mitsubishi 4M50ISU with a rated power of 118 kw at 2000 revolutions per minute.
Optimized System Matching:
It employs an international advanced hydraulic system. By setting action priorities and optimizing system throttling, it offers better operability and more precise actions. When the boom is lifted and the bucket is excavating, the oil flow within the valve enhances working efficiency. The bucket rod has a regeneration function, which accelerates the running speed of the bucket rod. Compared to the traditional model, the system pressure level is increased, the mining force is enhanced by 11%, and the internal channel of the main valve is optimized to reduce pressure transmission losses in the system, achieving a comprehensive fuel savings of 5% - 8%.
Boom:
The boom features a large cross - section design. High - load parts are strengthened, ensuring high durability. The optimized design prevents stress concentration on the bucket rod. The bucket rod is strengthened according to the force direction and magnitude during work, significantly improving its strength.
Bucket:
The bucket is made of high - wear - resistance material, which extends its service life.
Off X Rack:
Each process of the X frame is manufactured and processed using domestic and international advanced equipment, and non - destructive equipment testing is conducted on important parts. The track frame adopts a 7 - heavy - wheel structure design, with a standard of 45 sections of track plates, ensuring the reliability and stability of the vehicle under various complex working conditions.
High - Strength Structure:
Three - dimensional structure design and finite - element analysis are utilized to simulate the load on the fuselage, realizing a reasonable high - strength structure. The thickness of the high - strength left and right platforms and the high - rigidity turntable is increased, providing a guarantee for powerful excavation and high - speed travel.
