Abstract (en)
[origin: US2013341996A1] A self-propelling construction machine has a machine frame, an operating drum and a drum housing enclosing the operating drum. The drum housing is closed off by a front and/or rear sealing element and/or lateral sealing element. The construction machine has a mechanism for raising and lowering the at least one sealing element. A measuring unit is configured so that the measuring unit measures the forces acting on the sealing element when the sealing element encounters an obstacle. A control unit generates a control signal for raising the sealing element when the force measured by the measuring unit is larger than a predetermined limit value, so that the sealing element is raised.
