The Athey Blade - A New Concept for a Practical Maintenance Grading Machine 690370
This paper gives reasons for development of a new concept for a practical maintenance grading machine, including details of previous equipment and studies made to determine what improvements and new concepts could be incorporated. The engineering and manufacturing program planned and executed to complete design and development of a prototype unit within a specified time period is described.
Engineering features of the unit such as power train, hydraulics, and circuits are explained. Special emphasis is placed on the study made on appearance and styling; to the achievement of operating improvements; and to the design steps taken to insure ease of serviceability and machine maintenance.
Data are supplied on tests on the prototype including initial durability trials, engine performance trials, and subsequent field trials by a variety of operators. Results of these trials were then translated into improvements in the production model.
The paper concludes with a description of the production unit and gives applications for this equipment in construction and earthmoving industries.
