PURPOSE: A support unit of a scaffold for an LNG cargo work is provided to easily adjust the height of a scaffold during an LNG cargo work by rotating a pulley through a drive unit. CONSTITUTION: A support unit of a scaffold for an LNG cargo work comprises first and second load dispersion plates(110,120), a screw jack(130), a pulley(140), and a drive unit(150). The first load dispersion plate supports the load of a scaffold for an LNG cargo work. The second load dispersion plate is separated from the first load dispersion plate. The screw jack is arranged under the scaffold and is placed on the top of the first load dispersion plate. The pulley is hung on the screw jack. The drive unit is coupled to one side of the second load dispersion plate and rotates the pulley. |
