Abstract
Until now, authors investigated the structure of oxcart of Ephesus Museum in the first paper. And in the second paper, authors made clear the function of wheels and axel bearings which were found at local town Dinar. It was made clear that wheels of oxcart were fixed on an axle, and the axle was in contact with axle bearings directly. At first, authors thought that the structure exists only in the south-western part in Turkey. However, during investigations in north-west part of Turkey, the same bearing system was seen to an ancient two-wheeled truck having a long shaft which was discovered in a local town Edremit. The wheels had the same structure in comparison with reported results formerly too. In this third paper, The authors consider the ancient truck structure and bearing system based on the approximately decided figures derived from photographs taken.
