Abstract

The gantry is intended to be used to obtain access to the interior of spherical and spherically ended tanks and reservoirs with diameters of the order of 20 meters. The gantry consists of a tube (2) which is seated on a swivel plate (3). The top is located in a swivel head (4). At the mid point of the tube there is a collar (5) to which are joined two parallelogram arms (6a). The other ends of the arms are joined to a working platform which is close to the wall of the tank. A cable (10) runs from the platform to a pulley (11) and to an electric motor. The operator can control the movement of the platform.
