Abstract

A self-aligning tool guide has a holder for securing a portable power tool for working on a ceiling, a lifting mechanism, and a self-balancing chassis. The holder is mounted on the lifting mechanism. The lifting mechanism has a propulsion system for raising the holder parallel to a lifting axis. The self-balancing chassis has two wheels on a wheel axis and a drive coupled to the two wheels. A sensor serves for detecting a contact pressure of the holder, the contact pressure acting in the direction of gravitational force. The control station activates the propulsion system depending on the detected contact pressure.
