Patent ID: 10246313

Abstract:
A concrete pit for housing the below-floor part of a vehicle lift that is at least partially below floor level is constructed of precast concrete pieces. In one embodiment, a trench is dug slightly bigger than the pit that will be installed, and a precast concrete base slab is placed in the hole. Features around the perimeter of the base slab mate with corresponding features around the bottom of a precast concrete hollow rectangle, which is placed on top of the base slab. Additional precast concrete hollow rectangles may be placed on top. A vehicle lift is placed within the concrete pit and in some embodiments fixed thereto using holes, protrusions, or other features built into the concrete pit. In some embodiments, plumbing, wiring conduit, and other passageways are cast into the pieces of the concrete pit to minimize manual installation work that needs to be done in the pit.
