Portable A-Frame

Allied offers a unique portable A-frame that comes disassembled in a 20-foot sea container for transportability. The A-frame can be erected quickly with a small crane and two workers. The A-frame mounts to the 24-inch center to center bolt-down grid pattern provided on most research vessels. The A-frame can be broken down to clear the deck in short order. The Allied portable A-frame is perfect for the scientist who needs flexibility on the project and does not have need or budget for total vessel support.
