Product Details
The Underground Excavator, designed and manufactured by Shandong Cresics Equipment Manufacturing Co., Ltd., is a dedicated digging machine for coal mine underground operations. It not only boasts standard excavation functions but can also be fitted with a hydraulic breaker to perform crushing tasks inside mine roadways. Unlike products from other manufacturers, this model offers the following exclusive advantages:
1.Ultra-flexible for narrow roadway operations: Compact body with a height of less than 2.4 meters and zero-tail 360° rotation capability. Easy to turn around and operate in narrow roadways, and adaptable to all types of underground roadway sections.
2.All-round & high-efficiency performance: Capable of excavation, slag removal, milling, and support operations. Realizes quick accessory replacement, completing multiple processes without changing equipment, and delivers much higher efficiency than similar models.
3.Durable & low failure rate: Equipped with well-known imported core components and high-strength steel for key parts. Built-in multiple safety protection systems, ensuring stable operation even under heavy-load conditions with minimal maintenance requirements.
4.Worry-free experience with direct manufacturer: Factory-direct sales eliminate middlemen, offering cost-effective prices and customized solutions. Sufficient spare parts in stock, 24-hour after-sales response, free operation training and maintenance guidance, guaranteeing hassle-free post-purchase usage.
4.Explosion-proof design: Adaptable to various complex underground working conditions, especially suitable for high-gas underground environments.
