An under-cart type guided tractor comprising a frame (1) provided with a driving unit (3) including driving wheels (2) adapted to travel guided by a guide signal sent out from a guide element, such as a magnetic tape (14) laid along a travelling path on a floor surface (4), and to draw a cart (5) provided with free wheels (11) and loaded with goods, to travel over very uneven floors. The frame (1) of the guided tractor comprises at least two separate frame components (7,8) that are arranged in line with the travelling direction of the guided tractor and joined by a pin (9) in such a manner that the frame components (7,8) are allowed to take an upward or downward bent formation. The frame components (7,8) are equipped with a clamp mechanism (10) capable of being raised and lowered, the clamp mechanism (10) being adapted to be raised and clamp the frame (6) to the cart (5) when the guided tractor has come to an appropriate position under the frame (6) of the cart (5). A sensor (13) is provided at a portion suitable for detecting the guide signal sent out from the guide element, such as a magnetic tape (14). <IMAGE> |
