Abstract
An assembly for supporting the floating roof of a tank is provided that includes a guide fastened to the floating roof, a support leg slidably received in the guide and a locking pin. The guide supports the floating roof when the assembly is in an operating mode. In this mode, the support leg may be withdrawn from the guide. When the support leg is withdrawn, the locking pin is installed coaxial with the vertical axis of the guide, to close the orifice remaining upon removal of the support leg. When the roof is placed in a maintenance mode, the support leg is reinserted in the orifice and the locking pin is passed through aligned orifices of plates rigidly fastened to the top end of the guide. The transverse orientation of the locking pin in the locked mode enables an operator to determine the operating status of the floating roof.
