Abstract
A working machine having a base assembly including a ground engaging structure; an undercarriage connected to the ground engaging structure; a superstructure connected to the undercarriage; a working arm mounted to the superstructure; a connector connecting the undercarriage to the superstructure; and a drive arrangement located in the base assembly for moving the ground engaging structure to propel, in use, the working machine.
Claims15
A working machine comprising:
- a base assembly including a ground engaging structure;
- an undercarriage connected to the ground engaging structure;
- a superstructure connected to the undercarriage;
- a working arm mounted to the superstructure;
- a counterweight mounted to the superstructure;
- a connector connecting the undercarriage to the superstructure;
- and
- a drive arrangement located in the base assembly for moving the ground engaging structure to propel, in use, the working machine;
- wherein the superstructure comprises a bodywork portion having a first angled perimeter surface, an angle of the first angled perimeter surface being greater than 0° below a horizontal and less than 90° below the horizontal;
- wherein the first angled perimeter surface extends over at least a part of the bodywork portion of the superstructure and at least a part of the counterweight;
- the working machine further comprising an operator's cab mounted on the superstructure, wherein the counterweight comprises a surface abutting against the operator's cab, and wherein said counterweight surface comprises a recess for abutting against the operator's cab;
- wherein the superstructure comprises a second angled perimeter surface positioned on an opposing side of the superstructure to the first angled perimeter surface, an angle of the second angled perimeter surface being greater than 0° below the horizontal and less than 90° below the horizontal;
- wherein the angles of the first and second angled perimeter surfaces differ;
- and
- wherein the angle of the first angled perimeter surface below the horizontal is less than the angle of the second angled perimeter surface below the horizontal.
