  • 20 Ton A-Frame

    The attached file is an overhead view of a 20 ton capacity A-Frame that attaches to the rear of a ship. We had to load test it to 40 tons of course but thanks to miller, and to some hard working fabricators, all welds held.

          Located in So Cal. The Lift is for sea-born operations requiring a dual winch set-up, one on the right and one on the left; for positioning expensive equipment below sea level.

                        All in all, the Hydraulic pressure unit took one hundred fifty gallons to operate the frame, winches and other related components. The HPU is powered with a caterpillar engine. 2" Hydraulic lines were used along with 1 1/2" lines for the winches. We only had to climb the ladders once during re-assembly in Florida put I am sure those rungs will be getting used out at sea.
