ABSTRACT:
A vehicular device designed to operate in enclosed canals includes a swivel head (25) which is connected by means of a rotatable and/or vertically adjustable boom (manipulator arm) (2) to the front end of a main chassis (3). The main chassis is fitted with rotatable supporting arms (6, 7; 6',7') to which are attached, both above and below and equidistant to the midline of the main chassis, pairs of wheels (8, 8'; 9, 9'; 28, 28', 29, 29'). The supporting arm or arms are maintained by means of a power source (16, 16') in a position of maximal spread in relation to the main chassis.
