Heavy Duty Lifting Air Bags

Heavy object lifting air bags are usually used in various occasions, such as construction sites, warehouses, docks, etc., and can be used to lift and move various heavy objects, such as steel, mechanical equipment, cargo, etc.

Product Introduction
What is Heavy Duty Lifting Air Bag?
marine heavy duty lifting airbags

A heavy duty lifting air bag is a device used for lifting and carrying heavy objects. It is usually made of rubber or synthetic rubber and has good elasticity and durability. The air bag is filled with compressed gas and can be inflated and deflated to lift and move heavy objects.

Advantages of Heavy Duty Lifting Air Bag

 

High Lifting Capacity

Air bags create high lifting capacity with safer low pressure. One air bag can lift 300~500 ton.

 

High Tensile Strength

Heavy-duty synthetic-tire-cord layers are the framework material. It can bear high working pressure.

 

Resistant to Abrasion

Lifting air bags have 6~12 plies reinforcement layers to withstand most abrasion and puncture.

 

Scrollable

Heavy lifting air bags can roll with load that is extremely useful for load moving and lifting.

 

 

Construction of Heavy Lifting Airbags

 

Heavy lifting airbags are to be constructed of an out rubber layer, multilayer heavy-duty synthetic-tire-cord layers, and an inner rubber layer vulcanized firmly. Heavy lifting airbags are cylindrical balloon body, with two conical heads and two end mouths. Airtightness swivel and air inlet kits are screwed with end mouth.

 

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.

 

Common Types of Lifting Air Bags

 

Ship Launching Airbags

Ship launching airbags, known as roller bags or ship launching balloons, are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in a long cylindrical balloon shape. Ship launching airbags can be used for the ship launching, ship launching work. Ship launching technology using rubber airbags is accepted by more shipyards worldwide.

 

Heavy Lifting Air Bags

High-pressure heavy lifting airbags are the toughest large pneumatic lifting bags for the huge structure, concrete caissons lifting and moving. High-pressure heavy lifting airbags is updated based on the ship launching airbags. The highest lifting capacity of each heavy lifting airbag can reach more than 1,000 ton.

 

Marine Salvage Airbags

Marine rubber airbags are particularly suited for installation buoyancy on pipeline float-out, beach pulls, and river crossings. Our marine rubber airbags have also been used in applications such as vessel and platform draught reduction. Marine rubber airbags also can be used to salvage the shipwreck, rescue or float the floating bridge, and dock construction.

 

Heavy Lifting Airbags Application

Heavy lifting and transportation relying on heavy lifting airbag is cost effective and flexible. Evergreen Maritime heavy lifting air bags will provide you with a unique capability of land transport very large vessels, heavy loads, or heavy construction over ground where terrain would otherwise prevent such an operation.

The deflated marine airbag is very flat and can be placed under a grounded or stranded vessel that is hard aground. As little as 12 inches will provide very quick placement of marine air bag under hull.

 

Tips for Using Heavy Duty Lifting Air Bag

 

There are some precautions that need to be followed when using heavy objects to lift the air bag. First, choose the right air bag model and size to ensure it can handle the required weight. Secondly, make sure that the air bag has been fully inflated before use, and avoid over-inflation or deflation too quickly during use to prevent the air bag from rupturing or losing stability. In addition, pay attention to the operating temperature and humidity of the airbag, and avoid using it at too high or too low temperature and humidity.
In general, the heavy duty lifting air bag is a very practical device that can effectively improve work efficiency and safety.

Q: Can air bags be used to lift heavy objects?

A: Air lifting bags are capable of lifting heavy loads with relative ease and efficiency. Some of the largest bags are capable of lifting over 90 U.S. tons. Proper training and education are paramount to a successful lifting bag operation.

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. When the inner pressure reaches the rated value, it can open automatically to release the insider air-pressure. You can choose the required diameter and effective length to meet your projects.

Q: What is ship launching airbags?

A: Ship Launching Airbags. Also known as inflatable marine airbags, roller bags, air lift bags, and salvage bags. Airbags range in size from 0.8 to 2.5m diameter, with lengths of 5.0m to 25.0m 'effective length'. Airbags are used for ship launching, haul-outs, loading, and floating.

Q: How heavy is your rubber airbag?

A: The weight of ship launching airbags is calculated by airbag surface area. When you care too much about weight, you may be misled by some manufacturers. Please remember "It's not that the heavier the airbag, the better the quality. Weight is not a good indicator of quality."

Q: How many times your marine airbags can be used?

A: Marine rubber airbags are not single-use products. It can be used for many times. But cannot define the exact number. General speaking marine airbags have 5~8 years lifespan under the correct usage and proper maintenance.

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.
