8 Layers Barge Lifting and Launching Marine Airbags

Marine airbags are newly innovative devices for lifting and launching barges and ships nowasdays. The technology of launching and lifting barges by rubber airbags was developed being based on Slipway launching technology.Luhang marine airbags are pliable and tough. It supples moderate force to keep ship stable and not be damaged when ship launching.Luhang rubber airbags are designed for higher load capacity, wear resistance and Seawater corrosion resistance.Luhang marine rubber airbags are not only just used for barge lifting, launching & docking,but also be widely used for Salvage operations,Transfer heavy structure,Storage and transport some Gas or liquid,Erection of bridge and Water pipe Floating.

The structure of Barge Lifting and Launching Marine Rubber Airbag

A marine airbag consists of three parts:

1.The mouth: a set of metal valves mounted on both ends of the airbags for charging air. One end is often mounted to a lug to pull the airbags under the vessels.

2.The head: A conical part connecting the body and the mouth of the airbag

3.The body: The cylindrical part of the airbag after inflation(effective length of an airbag)

Initially established as Qingdao Luhang Marine Airbag Factory in 1988 and changed to Qingdao Luhang Marine Airbags and Fenders Co.,Ltd in 2011, Qingdao Luhang had been devoted itself to developing and manufacturing marine airbags and marine fenders for more than 2 decades.

The factory area is 56,000m² with building area of  21,000m². The company has registered capital of USD 3 million and fixed asset of USD1.2 billion. We have a full line of production equipment: rubber mixing machine, rubber roller machine, the China biggest vulcanization tanks, the biggest Press Inspection Machine, EVA foam processing machine, Foam shaping machines and SPUA spraying machine.

Through these years' development, we have full range of marine airbags and marine fenders:

Ship Launching Airbags for ship launching and docking in shipyards

Marine Salvage Airbags for salvaging sinked vessels or refloating objects from under water

Other Airbags for special usage

Pneumatic Rubber Marine Fenders for ships and docks berthing

Foam Filled Marine Fenders for ship and docks berthing

Fixed Dock Rubber Fenders for docks and wharfs

Marine Buoys

From the begginning we have been focusing on technological innovation. With a team of experienced technicans and engineers, we have developed some high tech marine products and got some petents. We have been approved as a supplier of Navy products. 

Quality is our life line. We provide service of “three guarantees” (returning, repairing and replacing) on all our products in case of any defects due to the problems of material,manufacturing, performance under conditions of normal operation and maintenance.
