Product Description
This integrated digger-loader is powered by a self-developed, enhanced-reliability torque converter and transmission system, delivering robust power output. Its reinforced engineering-grade chassis ensures stable mobility and heightened durability. The equipment offers three steering modes (crab steering, front-wheel steering, and four-wheel steering) to adapt to diverse operational environments, complemented by 16.9-28 tires featuring elevated ground clearance for superior off-road traversal capabilities.
The equipment employs full pilot control for both digging and loading functions, delivering lightweight operation and superior working efficiency.
The premium FOPS & ROPS-certified cabin integrates a humanized rotating shock-absorbing seat and fully tempered glass construction, ensuring panoramic visibility and optimized operator comfort.
Excavation operations are enhanced by a fully hydraulic lateral sliding mechanism, which expands the working range while reducing labor intensity, achieving both time-saving performance and heightened excavation efficiency.
A variety of accessories can be selected to complete a variety of construction operations. Used in municipal, construction, water conservancy, highway, water supply, power supply, garden and other departments, can be engaged in agricultural construction, pipeline laying, cable laying, landscaping and other operations.
