Benefits of Heavy Lift Air Bags

Heavy Duty, High Pressure

Our heavy lifting airbags use the special synthetic-tire-cord, which is stronger than the material used for the ship launching airbags. The highest working pressure can reach more than 400 kPa.

Super High Lifting Capacity

The maximum weight caissons move by heavy lifting airbags reach 5,000, cofferdams reaches 2,200ton.

Cost Effective, Flexible

The lifting and moving work using heavy lifting airbags doesn’t need the slipway, trolley. Low reaction force on the objects, safe for structure.

Construction Of Heavy Lift Air Bags

Synthetic-tire-cord layer

The Synthetic-tire-cord layer is the reinforcement layer of the ship launching airbags which are made of rubber-coated synthetic-tire-cord fabrics. Many synthetic-tire cord layers are twined at ideal angles by unique and patented "Holistic Wrapping Technology". To hold the internal pressure and to distribute the stress evenly. We use the 1870 dtex/2 type synthetic-tire-cord fabric. The warp is over 95 cords per 100 mm in width. The breaking strength is more than 310 N per cords.

Inner and Outer Rubber

Prior to the airbag production, the outer and inner rubber layers shall be tested to meet the criteria in accordance with the test methods given in the International Standards listed below. The outer rubber layer covers the outside of ship launching airbags. To protects the cord layers from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage.

Application of Heavy Lift Air Bags

Q: How much weight can an airbag lift?

A: A 12-inch × 12-inch air bag with its surface area of 144 square inches multiplied by 150 (the psi of air used to inflate the bag to its maximum capacity) provides a lift of 21,600 pounds, or 10.8 tons. This assumes the object being lifted is in full/flat contact with the bag.

Q: What is marine airbag?

A: Ship launching airbags are specialized air bags that are used for launching marine vessels. These air bags are made of synthetic-tire-cord reinforcement layers and rubber layers, and are also known as marine airbags.

Q: How do marine salvage airbags work?

A: Marine salvage airbags are equipped with lifting belts and shackles. For the big size, we also install safety valves.

Q: What's working depth of your marine salvage?

A: Our marine salvage rubber airbags can be used for surface buoyancy support and deep-water reflationary work. The suggested maximum working pressure is less than 50m. When you lift objects from the seabed to the surface, have to control the lifting up speed.
