Embodiment Construction

[0032] exist figure 1 A side view of one embodiment of a mobile work machine 10 according to the present invention is shown in , while figure 2 A front view of the work machine 10 is shown and image 3 A top view is shown. The work machine 10 comprises a travelable, ie including running gear, undercarriage 12 having a plurality of foldable supports 13 on which a superstructure 14 is rotatably supported. A boom, not shown further here, can be articulated at the superstructure 14 and can be pivoted about a horizontal axis. In general, a working machine according to the invention can be, for example, a material handling device or an earth-moving device such as an excavator, in particular a hydraulic excavator.

[0033] Work machine 10 may be controlled by an operator from cab 16 . The cab 16 is not directly connected to the superstructure but is connected via a lifting device. The lifting device comprises a lifting arm 20 which is connected to the superstructure 14 and the ...

Abstract

The invention relates to a mobile working machine that comprises an undercarriage, a superstructure rotatably supported on the undercarriage, a boom pivotably supported at the superstructure, and an operator's cabin mechanically connected to the superstructure via a lifting apparatus. The operator's cabin is adjustable in its height above the ground by means of the lifting apparatus, with the operator's cabin being able to be moved by means of the lifting apparatus from a working position spaced apart from the ground into a mounting position in which the operator's cabin sits on the ground. The lifting apparatus further comprises in accordance with the invention a lifting arm that is arranged between the operator's cabin and the superstructure and is pivotably supported at the superstructure about two non-parallel pivot axes independently of one another.

Description

technical field [0001] The present invention relates to a mobile work machine comprising: a chassis; a superstructure rotatably supported on the chassis; a boom pivotally supported on the superstructure; Structurally mechanically connected driver's cab which can be adjusted in height above the ground by means of the lifting device, wherein the driver's cab can be accessed by means of the lifting device from a working position spaced from the ground to the top in a vehicle position, and the working position is accessible from a boarding position, in which the driver's cab rests on the ground. Background technique [0002] Mobile working machines, such as material handling equipment or hydraulic excavators, are known from the prior art in various variants. Such work machines generally have a superstructure rotatably supported on a travelable chassis, to which, for example, one or more booms are articulated. Furthermore, such work machines usually comprise their own cab, whic...
