Mining Bolt Pull Tester

The mine bolt pull-out tester applies axial tension to bolts through a hydraulic system to detect the relationship between anchorage force and displacement. It is used for quality inspection of underground support to assess the reliability of bolt installation and prevent roof collapse.
Selection
When selecting, consider that the maximum pulling force must cover the design value of the anchor bolt, and the stroke must meet the displacement range required for on-site testing. Prioritize explosion-proof types to suit the mine environment, with digital displays for easy reading and a portable structure suitable for operation in narrow tunnels.
