Basic Info.
Product Description
Product specification
Our product uses XCG exclusive low-speed high-torque engine, after careful design and adjustment, it can achieve sustained stability and strong power output at low speed, and improve the power utilization rate and fuel economy. Powerful torque can meet the hydraulic system requirements and achieve faster working cycles.
For XMG, we use highly specialized design and analysis tools, combined with bench tests, to ensure that our machines are strong and durable. In addition, our materials and structures are rigorously tested for strength and toughness under the most extreme conditions.
Adopt the dozer blade that can move in parallel and the assistant stabilizing outrigger to improve the stability of the machine support. The outrigger and dozer blade in contact with the ground are carefully designed to prevent damage to the asphalt pavement. The support of the contact surface is enlarged to further reduce the bearing pressure of the ground.
The advanced wheel brake system makes the machine brake more effectively. It eliminates the rocking effect of the machine on the wheels when excavating. The transmission and axle integrated braking system can ensure the safety and meanwhile minimize the vibration of the whole machine, and effectively improve the braking stability.
Along with the self-developed intelligent control system of multi-functional attachments, the machine can perform multiple operations, including crushing, shearing, cleaning, compacting, milling and planning, pushing, clamping, grasping, scraping, loosening and lifting. It is widely used in the earthwork construction of city water, municipal engineering, pipeline maintenance engineering, civil engineering, industrial material loading and unloading, tunnel excavating, water conservancy engineering, urban demolition and relocation.
