When designing the rock wall crane beams in underground workshops, the direction in which the tensile anchor bolts extend from the surrounding rock is usually inclined downwards, aiming to balance the sliding and overturning resistance of the crane beam. Based on simulation model tests and prototype monitoring results, this study analyzes the bearing mechanisms and stress transfer patterns of the suspended anchor bolts at different loading stages, exploring the feasibility of arranging the tensile anchor bolts horizontally or nearly horizontally when structural stability is controlled by overturning. Combining this with a specific underground workshop rock wall crane beam, the rigid body limit equilibrium method and the nonlinear finite element method are employed to conduct overload calculations and compare the effects of horizontally arranged anchor bolts versus downward-inclined anchor bolts on stability. The results indicate that for rock wall crane beams whose stability is controlled by overturning, arranging the tensile anchor bolts nearly horizontally is more advantageous for enhancing the overall stability of the rock wall crane beam.
