Abstract: A mortar carriage includes a holder (10) for a tube (19) and two angularly related legs (11, 12). The legs have adjustment devices (112, 122) for adjustment of the length.A sensor (13) senses the incline of site and the elevation of the tube (19) and controls the electric motors (111, 121) which drive the adjustment devices (112, 122).Control devices with a counting unit (20) controls the automatic adjustment of the length of the legs (11, 12) by coarse adjustment of incline of site and elevation respectively and after that fine adjustment of incline of site and elevation respectively. At the adjustments for incline of site the actuation of the legs (11, 12) happens in opposite directions and at the adjustment for elevation the actuation happens in the same directions.
