Subsalve USA Professional Lift Bags 4400 lbs

The Subsalve USA Professional Lift Bag began with a one-of-a-kind assignment from the US Navy to develop a floatation device that would dependably withstand particularly abusive conditions. Subsalve developed the 5-ton deep ocean lift bag which had unprecedented strength, low elasticity and superior resistance to abrasion and chemical attack. This bag is now Subslave's Standard Professional Lift Bag design.

These open-bottom, balloon shaped bags with a single attachment point are easy to use in construction, heavy and light salvage, and many offshore tasks. The Professional Lift Bags are manufactured from heavy-duty, ballistic-rated nylon fabric coated with urethane. This specially-coated fabric is: high in strength, very-resistant to abrasion, most petrochemicals and UV. All Subsalve USA Professional Lift Bags are equipped with easy-to-operate fill and dump valves on the top of the lift bag.

Each bag leaves Subslave's manufacturing facility equipped with all necessary hardware and is ready for immediate use out-of-the-box. Each Subsalve USA Lift Bag is tested prior to shipping and must meet rigorous U.S. Department of Defense Requirements. Lift bags rated for below 2-tons (1814.4 kg) have multiple nylon lift straps sewn directly to the bottom of the lift bag which bares the load and has a safe working ratio of 6:1. They are fitted with Subslave's plunger dump valve which provides air control with a push-button at the top of the bag and a lanyard at the bottom of the bag as well as a 1/4" NPT inflation port. Vent air from above, beside or below lifting bag to achieve desired ascent rate.

The lift bags are designed with replaceable heavy-duty nylon webbing lift harness fabricated into the skin of the bag. They are fitted with a 3/4" NPT inflation port and a 3/4" bronze ball valve for deflation. All bags are similar in shape to an inverse water droplet at-the-moment of breakaway; this unique design provides maximum lifting capacity with the least total bag weight. It also provides an even distribution of stress over the fabric surface.
