Abstract

See full text

A shovel excavator with an upper carriage pivoting unrestrictedly on an undercarriage and with an attachment holder (6) for a boom (8) pivoting laterally at the front. The pivot shaft (5) is located a distance corresponding to at least half the conventional shovel width from the front edge (22) of the operator cab, so that when the boom is pivoted transversely and the shovel post (10) is folded up, together with the excavating shovel (11), this assembly remains within the contour of the upper carriage. Unhampered view forward and on the ground through the folded-up boom assembly is provided to the operator cab. The second pivot shaft (5) is located in the area between the travel track and the longitudinal center line L of the vehicle in one main excavating position of the upper carriage. Neither in the travel position nor in the main excavating position do the side walls of the upper carriage project laterally beyond the undercarriage.
