Abstract

Zusammenklappbare Stufen-Anlegeleiter für Aufzugschachtgruben, bestehend aus
- zwei Seitenholmen (1, 2) in Form von U-Profilen mit nach innen, d.h. aufeinander zu gerichteten Schenkeln (1.1; 2.1), und
- Stufen (3), die im wesentlichen die Form von U-Profilen haben, deren U-Profilschenkel derart an den Seitenholmen (1, 2) angelenkt sind, dass die Seitenholme (1, 2) relativ zueinander aufeinander zu bzw. voneinander weg verstellbar sind,

dadurch gekennzeichnet, dass die Schenkel (2.1) des Seitenholms (2), in den die Stufen (3) im zusammengeklappten Zustand der Leiter einklappbar sind, eine an die Stufenhöhe angepasste Höhe haben, während die Schenkel (1.1) des gegenüberliegenden Seitenholms (1) eine geringere Höhe als die Schenkel (2.1) haben.
