<p>A parking elevator comprising two continuous chains formed by interconnected links and adapted to hoist or lower cages in which vehicles are parked. Two drive wheels of polygonal configuration are adapted to drive the chains synchronously, these two drive wheels being positioned at the bottom part of the elevator. The chain links are interconnected by shafts in which the cages are suspended, these shafts also supporting guide rolls running in vertical guides supported on the elevator stand. The trailing end of each link presents a pressure surface, and follower means are provided at each apex of the two polygonal drive wheels for engagement in the pivot joint between two successive links of the chains and for pressing against these pressure surfaces.</p> |
