Mobile bore hole positioner for use in arrangement for alignment of marking device for drilling of holes in ground for installing rails for stacker crane, comprises detector for detecting deviation of position of bore hole positioner

摘要

The mobile bore hole positioner (1) comprises a detector, a control unit (7), and a traversing unit. The detector detects the deviation of the position of the bore hole positioner from a reference line (9), and the signal of the detector is fed to the control unit. The control unit deflects or moves the traversing unit for minimizing the deviation of the position of the bore hole positioner from the reference line. Independent claims are also included for the following: (1) an arrangement comprises a detector, which is arranged in the form of a camera; (2) a method for alignment of a drill or a marking device by a mobile bore hole positioner; and (3) a method for drilling holes in the ground by a mobile bore hole positioner.
