Product Introduction

Application Scope:

Suitable for excavating fully coal and semi-coal rock roadways with a unidirectional compressive strength of ≤50MPa.

Performance Features:

Adopts a transverse-axis high-strength retractable drum with a wide drum width, strong coal-dropping and fault-crossing capabilities

Compact overall structure with a low center of gravity, offering good operational stability and high reliability

Multi-motor independent drive with block-type layout, providing strong operational driving force, high efficiency, and easy status monitoring

Travel mechanism employs frequency conversion speed control technology, multi-gear stepless speed regulation, with a robust and efficient transmission system

Hydraulic system uses multiple filtration technology and advanced performance pump-valve systems, enhancing system reliability

Reasonably arranged onboard integrated hydraulic anchor bolt system with high torque, large thrust, fast drilling, and strong fastening force

During drilling and anchoring operations, workers are positioned under temporary supports, preventing injuries from roof falls and improving safety

Electrical system features a bus-based modular distributed design, adopting dual control (local and centralized), with reserved interfaces for remote communication and intelligent functions, enabling remote control based on user requirements
