<p>The invention relates to a method of operating a flow line (1) comprising two or more assembly stations (A1, A2, A3, A4, A5, A6) for the assembly of heavy machines such as wind turbine nacelles (3). The method comprising the steps of : installing a prepared assembly trailer (5, 5a, 5b,..., 5n-2, 5n-1, 5n) in the flow line (1) before or at a first assembly station (A1), connecting the said prepared assembly trailer (5, 5a, 5b,..., 5n-2, 5n-1, 5n) to at least one flow line tow bar (37), if the prepared assembly trailer (5, 5a, 5b,..., 5n-2, 5n-1, 5n) is installed before said first assembly station (A1) then: moving the said assembly trailer (5, 5a, 5b,..., 5n-2, 5n-1, 5n) to said first assembly station (A1), else: moving all the flow line assembly trailers (5, 5a, 5b,..., 5n-2, 5n-1, 5n) to the next assembly station (A1, A2, A3, A4, A5, A6), whereby the steps of moving the flow line assembly trailers (5, 5a, 5b,..., 5n-2, 5n-1, 5n) are performed timewise stepwise. The invention also relates to a flow line (1) for the same purpose.</p> |
