<p>PURPOSE:To attain continuous traveling without generating a gap while keeping an inter-truck distance for preventing the collision between plural self-traveling trucks, to improve the traveling density of the trucks, to form an efficient working line, to easily and safely attain the transfer of a worker without slipping his (or her) foot, to suppress the separation between front and back trucks due to various failures from exceeding a fixed range by an emergency connecting device, and to maintain a continuous working floor without generating a gap by the emergency connecting device acting as a towing device. CONSTITUTION:A cover body 40 is connected from one of the front and rear ends of a truck body 21, an inserting body 41 is connected from the other end and each self-traveling truck 20 is provided with a collision preventing detector 45 capable of optionally detecting the preceding self-traveling track 20 and optionally changing a detection distance and the emergency connecting device 50 for allowing approach/separation between front and rear trucks 20 within a fixed range is distributed to the front and rear ends of respective truck bodies 21.</p> |
