crawler raise boring machine for hard rock drilling

The crawler raise boring machine is an efficiently integrated drilling device featuring flexible relocation and intelligent operation capabilities. It is suitable for raise boring construction in mines, tunnels, and other complex geological conditions, significantly improving work efficiency and reducing operational costs.

Description

The Crawler Raise Boring Machine

The crawler raise boring machine is a highly integrated new type of drilling equipment, specially developed to address the limitations of traditional raise boring machines in terms of relocation, intelligent control, and hard rock operations. By organically integrating the main unit, power system, and crawler chassis, the equipment achieves efficient, all-in-one operation.

Main Features of the Crawler Raise Boring Machine

  • Integrated structural design with a tightly combined main unit and travel system allows for quick relocation without disassembly, greatly reducing auxiliary operation time.
  • Equipped with innovative technologies such as dynamic guide plate, proportional rod disconnection, and automatic rod conveying, significantly enhancing automation and intelligence.
  • The crawler chassis design provides excellent off-road capability and adaptability to various terrains, enabling efficient operation in complex and hard rock environments.
  • Significantly reduces manual intervention and operating costs while improving overall safety and operational efficiency.

Application Fields of the Crawler Raise Boring Machine

This machine is widely used in mine shaft construction, hydropower projects, geological exploration, and other fields. It is especially suitable for engineering projects that require frequent relocation or operations in complex geological conditions for raise boring tasks.
