Wedge type chocks with the corresponding inclination only be used. The material can be cast iron or steel. Surface treatment: The supporting surface of the top plate has to be milled. When fitting the chocks, a bearing contact of min. 80 % is to be obtained. Outwards inclination of top plate are needed in case of usinf steel chocks. Withour this it is not permissible to install steel chocks. M 25 C Propulsion - 04.2012
