    • 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.
    • 用于容纳至少部分在地板下方的车辆的地板下部分的混凝土坑由预制混凝土构件构成。 在一个实施例中,沟槽比将要安装的坑略大,并且将预制混凝土底板放置在孔中。 基板周边的特征与预制混凝土中空矩形的底部周围的相应特征相配合,预制混凝土空心矩形位于基板的顶部。 其他预制混凝土中空矩形可以放置在顶部。 车辆升降机被放置在混凝土坑内,并且在一些实施例中使用孔,突起或内置于混凝土坑中的其他特征固定到其上。 在一些实施例中,管道,布线导管和其它通道被浇注到混凝土坑的块中以最小化需要在坑中完成的手动安装工作。
