Product Introduction

This "best-selling diesel excavator for underground coal mines"; is specially developed for road maintenance, drainage channel formation, cinder removal, waste management and surface grading in confined underground working Spaces. Its compact design is made of sturdy materials and can withstand extreme underground environments, with priority given to achieving outstanding mobility in restricted areas. This device has the ability to perform 360-degree rotation within the smallest spatial gap and supports multi-functional tasks such as material excavation, ground leveling, lateral excavation, rock crushing and bulk loading. It effectively addresses challenging tasks, including uneven drainage ditches, coal dust removal, waste treatment and road repair.

The rotating superstructure facilitates full circular flaking beneath the conveying system for material extraction and excavation. Its articulated arm assembly can be broken and excavated without obstacles at different heights within the tunnel network. Configurable front blades can enhance the stability of the machine during operation and help smooth the surface. The key hydraulic pipelines along the working arm are shielded by a spring armored housing to minimize the wear of the hoses under harsh conditions.

This excavator integrates an intelligent pressure-response hydraulic system, which can automatically synchronize power transmission with operation requirements while ensuring precise motion control during load handling - a benchmark innovation in contemporary construction equipment. This device adopts a compressed air ignition mechanism, which ensures reliable start-up. It also employs advanced emission control technology, using water filtration to neutralize toxic exhaust gases, thereby promoting safer underground air quality.
