SEA USA · Heavy-duty hydraulic swing operator

Super Full Tank. For the gates nothing else will move.

SEA's heaviest hydraulic swing operator, which SEA bills as the most powerful operator on the market. It comes in two strokes: 20″ for leaves up to 30 ft or 4,500 lb, and 40″ for leaves up to 40 ft or 5,500 lb at continuous duty.

    Two strokes · one platform

    Pick the stroke by the leaf.

    Both run on 120 V with the UNIGATE 2I inverter board, hydraulic slowdown, and bypass-valve anti-crush. The 40″ stroke carries the longest, heaviest leaves at continuous duty.
