Abstract

Ein Bagger mit einem Löffelstiel (22) und einer Schaufel (26), die mittels eines Hydraulikmotors (30) verschwenkt wird, enthält ein Gestänge, das sich aus einem drei Lagerstellen (46, 48, 50) aufweisenden Betätigungslenker (44) und einem zwei Lagerstellen (50, 54) aufweisenden Führungslenker (52) zusammensetzt. Der Betätigungslenker (44) ist einenends mit der Schaufel (26) und anderenends mit dem Hydraulikmotor (30) verbunden und dazwischen an den Führungslenker (52) angeschlossen, der anderenends an dem Löffelstiel (22) angreift. Die mittlere Lagerstelle (50) des Betätigungslenkers (44) ist gegenüber der ersten und der zweiten Lagerstelle (46, 48) von dem Löffelstiel (22) weg versetzt.

Figure 00000001
An excavator with a dipper stick (22) and a bucket (26), which is pivoted by means of a hydraulic motor (30), contains a linkage which is composed of an actuating link (44) having three bearing points (46, 48, 50) and a two Assembling bearing points (50, 54) guide link (52). The actuating link (44) is connected at one end to the bucket (26) and at the other end to the hydraulic motor (30) and is connected in between to the guide link (52) which on the other end engages the dipper arm (22). The middle bearing (50) of the actuating link (44) is offset from the dipper arm (22) with respect to the first and second bearing points (46, 48).
