Product introduction

Product selling point

1. For different formations and lithologies, the EBZ260 cantilever roadheader can be equipped with hard rock cutting heads and mudstone cutting heads with different numbers of picks to improve rock breaking capacity and construction efficiency.

2. The hydraulic system adopts constant power, pressure cut-off, and load-sensitive control technology to effectively increase the life of hydraulic components and reduce system failures.

3. The industry's first air-cooled independent heat dissipation system is applied to the roadheader, and the hydraulic system and the cutting motor are integrated and forced to cool.

4. The loading and transportation mechanism adopts high-strength wear-resistant plates to better adapt to hard rock conditions and increase service life.
