摘要：

A screen-handling stinger extends and retracts hydraulically from within a bore of a hydraulic stinger of a rock bolter. The screen-handling stinger has a finger that engages a screen. The screen-handling stinger retracts the screen until it snugly abuts the front face of a pad of the stinger. The screen can then be rotated by the rotation motor of the stinger. 100 115 116
