Air Lifting Bags Type

01
Underwater Lift Bags
Underwater lift bags are open or enclosed bottom parachute type design. These underwater air lift bags include commercial diving lift bags and professional lift bags.
- Features:Advanced design according. HF welding seam technology. ISO 9001:2015 strict quality management system. Top quality with competitive price.
- Applications:Used for the scuba diving lift bags, marine salvage bags, lift bags salvage, floatation bags salvage, and float bags salvage.
02
Marine Salvage Bags
SunHelm marine salvage bags are totally enclosed cylindrical shape design. It is known as enclosed air lift bags, inflatable buoyancy units, or salvage pontoon.
- Features:Advanced design according. HF welding seam technology. ISO 9001:2015 strict quality management system. Top quality with competitive price.
- Applications:Used for buoyancy support, marine salvage and re-floatation operation.


03
Enclosed Flotation Bags
SunHelm float bags salvage tube is enclosed and elongated cylinder shape. Its main capacity is from 500kg to 5,000kg. These are the salvage tube of choice when shallow water is a critical factor and towing is a concern.
- Features:Advanced design according. ISO 9001:2015 strict quality management system. Top quality with competitive price.
- Applications:Used for salvage towing, shallow water, and rigging.
04
Pillow Lift Bags
Enclosed pillow lift bags, known as enclosed flotation bags, is one kind of versatile marine salvage bags. Pillow lift bags are used in underwater salvage more than any other style underwater air lift bags.
- Features:High strength PVC coating fabric material, which is highly abrasion, and UV resistant.
- Applications:Perfect for vessel salvage, automobile recovery and emergency floatation systems for ships, aircrafts, submersibles and ROV.


05
Twin Inflatable Cable Floats
SunHelm develop twin boom inflatable cable floats is the very best solution for cable and pipeline installation support.Manufactured as two individual boom floats connected by a length of fabric (Professional Type) or strap system (Premium Type) to support the cable or pipeline. The cable or pipe is placed on the support system easily.
- Features:High strength PVC coating fabric material, which is highly abrasion, and UV resistant.
- Applications:Used for the buoyancy support for the pipeline, cable installation.
06
Mono Buoyancy Bags
SunHelm single point buoyancy units are one-kind enclosed pipeline buoyancy bags. It only has one single lifting point. So it is very effective for the steel or HDPE pipelines laying work at or near the surface.
- Features:Advanced design according. ISO 9001:2015 strict quality management system. Top quality with competitive price.
- Applications:Used for the buoyancy support for the pipeline, cable installation.


Buoyancy Cases
These products are widely used in marine engineering, salvage operations, and heavy equipment handling. With core advantages such as high load capacity, rapid inflation/deflation, and corrosion-resistant materials, they provide safe and reliable buoyancy support for water-based operations.
Water Weight Bag Overview
Water weight bags are simple and safe water filled crane test weights designed to provide proof load testing instead of traditional solid load test weights.
SunHelm Marine load test water weight bags are designed for proof load testing the lifting equipment and structures that request proof load weight testing. When it’s newly finished, or periodic check or maintenance. Such as crane load testing, beam load test, lifeboat davit load test, derrick load testing, overhead crane load test. So, this water-filled water weight bags offer one kind of innovative crane load test weights solution. Most noteworthy, it has the advantages of Safety, Economy, Convenience, High Efficiency.
