Salvage Pontoon

Totally-enclosed, cylindrical bags are ideal for shallow water salvage, reducing the draft of a vessel or raising an object closer to the surface. They are invaluable in cable and pipeline operations, and where long tows are planned. Fabric• Urethane-coated nylon—high-strength and heavy-duty• Superior abrasion resistance• Resistant to most petro-chemicals• UV-resistant• Low maintenance requirements and easy to clean• RF welded seamsFittings• Replaceable, heavy-duty nylon webbing lift harness is built into the body of the lift bag, with a safe working ratio of 6:1• The harness maintains the lift bag in a horizontal position while insuring maximum stability• Equipped with shackles, valves and all necessary hardware for immediate use• 3/4" NPT inflation port with 3/4" stainless steel ball valves for inflation and deflating• Stainless steel quick disconnect for inflation• Pressure relief valves set to release at 2.5psi above ambient pressureAvailable in both standard cylinder and elongated tubesStandard lift capacities range from 1,000 LBS to 100,000 LBS. Custom sizes available.

Enclosed Flotation Bag

When you need to float an object close to the surface, use SUBSALVE’s “pillow” shaped Enclosed Flotation Bags in any position—upright or flat, outside or inside of structures—for vessel salvage, auto recovery, pipeline and cable installation and emergency  flotation for ships, aircraft, submersibles and ROVs. Adaptive• Configure a multitude of rigging combinations.• Use with a single pick point (shackle supplied on the bottom of the bag).• Invert to use the multiple stainless steel rings on the top of the bag. Fabric• Urethane-coated nylon—high-strength and heavy-duty• Superior abrasion resistance• Resistant to most petro-chemicals• UV-resistant• Low maintenance requirements and easy to clean• RF welded seamsLifting Harness• Heavy nylon lift harness built into the body of the lift bag• Safe working ratio of 6:1Safe and easy to use• Equipped with all necessary hardware—ready for immediate use• 3/4" NPT inflation/deflation port equipped with ball valve• Stainless steel quick disconnect for inflation• Pressure relief valves: set to release at 2.5 psi above ambient pressure• Enough pressure relief valves are installed in each bag to allow expanding to vent should a free ascent occur.Standard lift capacities range from 200 LBS to 6,000 LBS. Custom sizes available.

Professional Lift Bag

Our most versatile and easy-to-use, these open-bottom, parachute-shaped lift bags with a single attachment point are essential in construction, heavy and light salvage and many offshore tasks.• “Inverted water droplet” design facilitates maximum lift capacity with least possible weight, with stress distributed evenly over the fabric surface.• Equipped with all the necessary hardware and ready for immediate use.• Each SUBSALVE USA lift bag is tested prior to shipping. Fabric• Urethane-coated nylon—high-strength and heavy-duty• Superior abrasion resistance• Resistant to most petro-chemicals• UV-resistant• Low maintenance requirements and easy to clean• RF welded seamsEasy to use• Proprietary Plunger Dump Valve - air control with push-button at top of bag and lanyard at bottom. Vent air from above, beside or below lift bag to achieve desired ascent rate as well as 1/4" NPT inflation port. Below 2 tons– Multiple nylon lift straps sewn directly to bottom of lift bag, which bears load and provides safe working ratio of 6:1.2 tons and over– Designed with a replaceable heavy-duty nylon webbing lift harness fabricated into the skin of the bag, which bears the load and provides a safe working ratio of 6:1.• Fitted with a 3/4" NPT inflation port with quick disconnect or cam lock fitting and a 3/4" stainless steel ball valve for rapid deflation.Standard lift capacities range from 1,000 LBS to 100,000 LBS. Custom sizes available.
