<p>PURPOSE: A deck lifting system is provided to drastically reduce costs which are spent on the manufacturing, processing, and maintaining of a support pin by replacing a lifting unit, which is driven by a rack gear and a pinion gear which interlock, with a lifting unit which uses a support pin. CONSTITUTION: A deck lifting system (1) comprises a rack unit (100) and a pinion unit (200). The rack unit is combined with a leg (L) which supports a deck (D) of a marine structure or a marine work vessel, and equipped with multiple support pins (120) which are mutually detached. The pinion unit is prepared on the deck, and lifts the deck up and down by delivering the power, which is transferred from a power transmission unit installed on the deck, to multiple support pins. The multiple support pins are made of high tensile steel.</p> |
