ARD inflatable rubber air bag ( Pass CCS,ABS,DNV of lifing air bag )is a kind of innovative product with our own intellectual property.It has been widely used in the ship launching and landing,the caissons lifting movement, the removal of other heavy objects, underwater installation work buoyancy aid and other areas. Marine airbag applications are not affected by site constraints, and don't need largescale machinery and equipment,so that to shorten the project cycle and save a lot of money. After 20 years of development practice,prove that it is safe,efficient, green,and flexible.
ARD heavy lift pneumatic rollers ( airbags) 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 ARD RUBBER have wide heavy lift pneumatic rolling airbags in capacities from 70 tons to 380 tons per bag. ARD also has a selection of bags with diameters up to 2m in diameter and up to 20m in length to cover virtually all applications.
advantages of pneumatic rubber airbag used as formwork in construction of pipe culverts :
1.High strength,anti-aging
2.Good air tightness,safety and reliability
3.High shock absorption,less reverse impact on ships
4.High kneading
The structure of pneumatic rubber airbag:
It consists of a bag body and an iron-end component. The bag body is manufactured by vulcanizing the preliminary shaped airbag made of base rubber and reinforced fiber material. The material of the iron- end component is metal, and it is connected to the bag body firmly.
pneumatic rubber airbags application:
1.Hoisting and moving airbags: They can be widely used for moving various large prefabricated reinforced-concrete products (such as caisson, box culvert, and bridge), oil drilling equipment and integrated building, etc.
2.Floating and filling airbags:The corresponding buoyancy can be offered on the clients’ request for wreck salvage and underwater installation operation. Filling and floating gasbags can be flexibly used in the projects of wreck salvage, pontoon bridge installation, dock building, underwater transmission pipeline installation, etc. in many ways.
3.Ship landing and launching airbag: It is widely used for landing and launching the large-size, medium-size and small size ships, with the advantages of labor-saving, time-saving and capital-saving.
4.Mandrel airbag: It can substitute the wooden or steel mandrel used for pouring the hollow of large reinforced concrete structure.
5.Container airbag:It can be used as the gas or liquid storage and transport container.
Standard specifications of pneumatic rubber airbag:
1> Diameter (D) : From 0.3m to 2.2 m.
2>Effective Length (EL) : From 6m to24m.
3>Total Length (TL) : From 7m to28m.
4>Other specification of ship launching airbags also available upon customer’s request
