ABSTRACT:
This invention provides a convenient apparatus and method for mounting equipment in an underground vault to provide convenient access to the equipment whenever such access is necessary. The vault mount includes a frame having one end thereof permanently pivotally mounted to the frame releasably attached to a second wall of the vault. Suitable springs are mounted between the first wall of the vault and the frame to urge the frame to pivot about the mounting to the first wall. When the second end of the frame is released from its wall mount, the frame and the apparatus mounted thereon pivots from a generally horizontal position in the vault to a generally vertical position with the equipment mounted on the frame extending out of the vault.
