Coal Mine Bolt Tension Meter_Auxiliary Equipment_Products and Solutions_Shandong xiangde Electromechanical co., ltd

Product Introduction

This equipment is specifically designed for quality testing in bolt-shotcrete support engineering. Through high-precision measurement of bolt strength, anchoring force, and anchorage quality, it provides data support for the safety of roadway support in coal mines. Integrating automatic anchoring and anchor removal functions, the built-in tool anchor enables one-button control, avoiding errors from manual intervention, enhancing operational safety, and shortening construction periods. It is compatible with multiple types of top pressure applicators. The exposed steel strand length is ≤ 20 cm, reducing safety hazards and meeting the construction requirements in narrow roadways. Adopting a modular structure and digital display technology, the operation interface is intuitive, and data feedback is precise and reliable, making it suitable for bolt quality acceptance and engineering evaluation under complex geological conditions.
