Abstract
A self-propelled construction machine includes a machine frame and an operating drum arranged in a drum housing which is open downwards and is closed on both sides by an edge protector which is adjustable in height. A control assembly determines a reference value for the height of the ground surface relative to the machine frame on which the edge protector rests in a floating position, the height of the edge protector relative to the machine frame and the lowering speed of the edge protector. Furthermore, the control assembly is configured such that the height of the edge protector relative to the machine frame is determined at the point in time at which the lowering speed of the edge protector is less than a specified limit value. Preferred embodiments of the machine furthermore detect the edge protector sinking into the ground, and/or prevent the edge protector from digging into the ground.
