Commercial Lift Bags offer simple operation with powerful functionality, making them an ideal solution for light salvage, object recovery, underwater construction, and scientific research. Designed for ease of use by a single diver, these lift bags provide a cost-effective alternative to cranes or barges, particularly in remote or shallow-water locations where rapid deployment from small craft is required.
Manufactured by Subsalve USA, these bags are constructed from urethane-coated, high-strength nylon with RF-welded seams, delivering excellent abrasion resistance, UV stability, and resistance to petro-chemicals. The rugged yet lightweight design ensures low maintenance and easy cleaning between operations.
Each bag is fitted with Subsalve’s proprietary Plunger Dump Valve, allowing precise buoyancy control. Air can be vented from the top, side, or bottom of the bag using a push button or lanyard, enabling controlled ascents and accurate positioning of lifted objects. A 1/4″ NPT inflation port supports remote filling, manifolding multiple bags, or fitting an optional stainless steel quick-disconnect.
High-strength, resin-treated nylon lift straps are sewn directly into the base of the bag, providing a 6:1 safe working ratio and dependable load transfer. Supplied factory-equipped with all required hardware, these lift bags are ready for immediate use on site.
