Abstract

A description is given of a method for testing the stability and bending strength of poles (1) which are anchored upright, in which in each case the pole to be tested is subjected to a variable bending moment, as well as of a device for carrying out the method. The device comprises a force unit (2), which with an increasing force (F) can be introduced into the pole (1) above its anchorage and the pole can be loaded with a bending moment, as well as a force sensor (4) to measure this force, whose level and variation can be evaluated to determine the stability of the pole. In this arrangement, provision is made of a distance sensor (5), which can be brought into contact against the pole above the pole anchorage, to measure the lateral deflection (S) of the pole occurring because of the bending moment, and the measured values generated by the force and distance sensor can be simultaneously processed in an evaluation circuit (6.1, 6.2) and can be displayed with reference to their mutual dependence. A linear variation of this dependence up to a desired testing force shows in this arrangement that the pole (1) and its anchorage are in order. If, before reaching the desired testing load, a transition of the relationship between loading and deflection value from a linear into a non-linear variation is indicated, a plastic deformation of the tested pole is present, that is to say a pole is present which is damaged. <IMAGE>
