Bolt dynamometer 
 Anchor bolt tension meter dynamometer dynamometer mining bolt 
 Dynamometer is to measure the anchor bolt force changes in equipment, it works in the common types of bolt and cable can be used. Anchor by testing conditions in order to monitor the quality of roadway , and thus on the tunnel, cavern, rock stress (stress appears) to monitor, is the study of bolt dynamometer roadway, the stability of caverns essential monitoring equipment. bolt dynamometer metal is mainly used for coal mine Bolt and Anchor axial tensile testing up, pull up the value of their directly by the pressure gauge pointer indicates.
