Patent ID: 8813916

Claim:
An underground system comprising: an underground enclosure having a floor and walls defining an opening; a cover for the opening in the underground enclosure; a seal intermediate the cover and the underground enclosure, the seal and the cover configured to selectively occlude the opening; a first scissors lift and a second scissors lift, each scissors lift moveble between a retracted position and an extended position, wherein the first scissors lift is spaced apart from the second scissors lift; a rack having a first and a second sidewall and a bottom panel extending between the first sidewall and the second sidewall, the rack positioned beneath the cover, the first sidewall adjacent the first scissors lift and the second sidewall adjacent the second scissors lift, and the cover coupling the first sidewall relative to the first scissors lift and the second sidewall relative to the second scissors lift, each of the first and the second scissors lift having: a first plurality of scissor linkage units and an opposed second plurality of scissor linkage units, each scissor linkage unit having a pivot interconnecting arms of the scissor linkage units at a central position of a respective arm and terminal ends pivotally coupling one of the scissor linkage units to another one of the scissor linkage units, wherein one of the plurality of linkage units is slideably coupled to a base, the first plurality of scissor linkage units and the second plurality of scissor linkage units separated by a given distance; and, a scissors lift moving piston having a first end coupled to one of the scissor linkage units and a second end coupled to another one of the scissor linkage units, wherein the scissors lift moving piston translates the scissors lift between the retracted position and the extended position and the scissors lift moving piston is located within the given distance.
