The Allied stern-mounted A-frame has a robust design with a wide range of capacities and dimensions. The A-frame is hydraulically powered and swings outboard to give clearance over the stern for launching and recovery of trawls, nets, dredges and ROVs. As an option, the A-frame can be folded down to within 60 inches of the deck surface for maintenance and servicing. Additional options include lighting, walkways, tugger winches and pivoting cross bar.
