Ro-ro vessels car deck plate hole cut way of lashing

摘要

In order to minimize the deformation of the card deck plate, the lashing holes are drilled in the carcass plate so as to have a width larger than that of the lashing holes drilled in the longitudinal direction by the perforating means in the width direction of the catech plate, ; And immediately after the punching operation of the single row of lashing holes in the width direction of the plate of the cardboard is completed, the lapping operation to the perforated lashing hole is immediately effected . Accordingly, it is possible to secure high reliability in the card deck plate, and to maximize the efficiency of the machining operation due to the perforation and finishing operations.
