Abstract
A large container 12 has a narrow top opening 14. An apparatus 10 is collapsible to be insertable into the container via the opening. When inside the container, arms 18 are opened outwardly from a central chine 24. Castor wheels at ends of the arms roll along an inner wall surface 18 to stabilize the apparatus and to allow displacement thereof. Service operations such as inspection, cleaning, maintenance and repair of the surface can be effected from the apparatus which serves as a platform. The service operations can be effected manually, or by means of remote controlled or automatically controlled service devices mounted on an arm.
