<p><P>PROBLEM TO BE SOLVED: To appropriately stop traction of a line upon generation of an overload on the line of work trucks. <P>SOLUTION: When pulling the work trucks forming the line on a production line, the gross weight of the line after detachment or addition is calculated when the work truck is detached from the line or is added to the line (steps S12, S14 and S34, S36), tractive force sufficiently required for conveyance is calculated based on the gross weight (steps S16, S38), and the tractive force of a traction unit is controlled to the calculated sufficiently required tractive force at a timing of detaching the leading work truck from the line or a timing of adding a new work truck to the line (steps S18, S20 and S40 and S42). <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
