After successfully delivering 7 wheeled excavators on November 1st, SDLG Small Agricultural Equipment Division once again received good news - a large construction machinery leasing company in Beijing has purchased 6 SDLG wheel excavators, fully demonstrating the continued influence and customer recognition of SDLG secondhand excavators in the capital market. This delivery not only further consolidates SDLG's market layout in the North China region, but also lays a solid foundation for further deepening the urban construction field. Among the 6 devices delivered this time, there are two star models, 4 EA7150H and 2 EA770H. As a 15 ton medium-sized wheeled excavator, EA7150H is equipped with a unique four-wheel suspension adaptive adjustment system, which has excellent overall stability and adaptability to working conditions. The machine has a working mass of 13600kg, a rated bucket capacity of 0.6m ³, a maximum excavation force of 94kN, and a climbing ability of 30 °. It is suitable for heavy-duty operations such as foundation excavation and earthwork transportation. The hydraulic system adopts dual pump constant power negative flow control and pilot proportional control, combined with a high torque engine, which not only responds quickly but also significantly improves work efficiency, fully meeting the high-intensity construction needs. The 7-ton EA770H is highly favored for its excellent flexibility and compact design. The EA770H adopts a compact design, with a small turning radius and a rotatable chassis, which can flexibly navigate through space limited working conditions such as renovation of old residential areas and underground pipeline construction. Equipped with internationally renowned hydraulic and transmission systems, the EA770H maintains efficient operation while maintaining low failure rates and high economy, and is widely used in diverse construction environments such as municipal, water conservancy, agriculture and forestry. The cab adopts a high-strength frame structure, with a wide field of view and significantly improved sealing and impact resistance compared to the previous generation. Coupled with shock-absorbing seats, the comfort of operation is greatly improved, effectively relieving long-term work fatigue.
