Medium-Small Section Twin-Boom Roof Bolting Rigs_Coal Mine Hydraulic Roof Bolting Rig_Drilling Rig Series_Products and Solutions_Shandong xiangde Electromechanical co., ltd

Product Introduction

This series of bolting rigs is specifically developed for small to medium cross-sections (20-25 m²) in roadways, integrating multiple functions such as synchronous roof and sidewall support, blast hole drilling, and geological exploration. The equipment features a fully hydraulic control platform equipped with dual-powerhead drilling arm groups, supporting multi-angle collaborative drilling or independent operations. Combined with a three-dimensional rotating mechanism, it achieves three-dimensional construction coverage. Equipped with an intelligent height adjustment system, including a front roof support mechanism and an adaptive lifting platform, it adjusts roadway roof support height in real-time through pressure sensing. The working platform can be synchronized for lifting, accommodating the needs of different cross-section constructions, thereby ensuring operational safety, and improving spatial adaptability. The machine integrates high-strength hydraulic pipelines and a precision filtration system to meet the demands of high-intensity continuous operations.
