<p>The invention relates to an apparatus for adjusting width and height of undercarriage (2) of passenger case elevators (G) having an underframe (1) connected to the undercarriage (2) as well as a cage lifting unit (E) with a cage (K) mounted on the underframe (1 ). Shore elements (3) are rigidly fixed to the undercarriage units (16, 17) of undercarriage (2) and upper and lower bolt holes (4a, 4f) to rotatably receive undercarriage bolts (5) are formed on each shore elements (3). The undercarriage bolts (5) are embedded in a first bolt hole (8) of upper and lower hinges (6, 7) each latter also having a second bolt hole (9) rotatably receiving a hinge bolt (10) partly embedded in a bolt hole (12) arranged on the underframe (1). A third bolt hole (13) is formed in an upper hinge (6, 7) connected to at least one shore element (3) by each undercarriage units (16, 17), said third bolt hole (13) receives a securing pin (14) partly fitted into either securing bolt hole (15) of at least two securing bolt holes (15) formed on the underframe (1). The bolt holes (4a, 4f, 8, 9, 12, 13, 15) are parallel to each other, respectively.</p> |
