The users of construction machinery demand higher quality. It is especially difficult to satisfy them with large-size bulldozers designed according to conventional design concepts that is, a new design concept is required now.Komatsu is putting the D475A, built by fully redesigning the D455A bulldozer, on the market. When developing this model, its power-train system, undercarriage, frame, etc., were redesigned under a new concept that emphasized moving large amounts of soil effectively, and new structures were developed as a result.In this paper, the design concept of the D475A and the structure that attained that concept will be outlined.
