Abstract

The invention relates to a method for controlling slip form pavers. According to said method, the positions of two reflectors arranged on the longitudinal carriers of a machine frame are determined by means of measuring devices for determining positions, especially tachometers, arranged at defined points in a reference area. The positions of four points on the slip form pavers or the slip form paver plank in the reference area are determined from the position information and measurement by means of two gradient sensors arranged on the machine frame. The slip form paver, and thus the mounting height and position of the plank which is arranged in a defined manner in relation to the slip form paver, are automatically controlled by a comparison of the determined actual positions of the four points with the nominal positions thereof.

Claims (14)
