EBH (Q) 260 medium-hard rock curved arm roadheader

EBH (Q) medium-hard rock curved arm roadheader is a series of multifunctional roadheader developed by our company based on the current domestic large, medium and small mine roadway excavation and mining. It replaces or mostly replaces the blasting excavation in the medium-hard rock roadway excavation and mining, and solves the problems of medium-hard rock roadway excavation and mining instead of blasting excavation and mining. It is mainly used in mine roadway, water conservancy engineering, national defense engineering, and urban comprehensive pipe gallery engineering.
This series of curved arm roadheader has the following performance advantages:
1. Combining the advantages of roadheader and bucket loader, it has the advantages of small volume, convenient disassembly and assembly, easy transportation and installation down the shaft, and is more suitable for the excavation and mining of small and medium-sized sections;
2. Compared with traditional single-arm roadheader, this kind of roadheader has the following advantages;
(1) The working mechanism adopts a curved arm structure, which makes tunneling and mining faster, more convenient, more efficient, and more flexible. It also has the functions of auxiliary loading, roadway repair, and risk elimination;
(2) The world's most advanced stepless variable speed cutting head is adopted, with high cutting power, which can meet the requirements of medium hard rock cutting, and can ensure stable operation, low vibration and long service life;
(3) The hydraulic system adopts the most advanced hydraulic components in the world to ensure its strong internal power, and uses load sensitivity and pilot operation. In addition, it also uses a water-cooled and air-cooled dual cooling system, which is flexible in operation, efficient in energy saving and long in continuous use;
(4) The machine adopts imported motor with large driving force, strong structural rigidity, flexible and convenient walking, and is suitable for slopes below 25 °;
3. The starwheel loader is driven by hydraulic motor, which works reliably and has high slag removal efficiency;
4. The transportation trough continues the advantages of our company's slag extractor transportation mechanism, and has the advantages of no slag jam, no floating chain, and high efficiency;
5. The machine also adopts an efficient spray dedusting and cooling system to improve the working environment;
6. The machine adopts advanced electronic control system, which can meet 660/1140V power supply modes.
