Marine rubber airbag for floating dock operation 1.Usage of Marine Airbags Ship Launching Marine Airbags, also known as roller bags or ship launching rubber balloon, are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in long cylindrical balloon shape. Marine Airbags for Ship Launching and Dry Docking for barge can be used for n Brazil, Indonesia Shipyard especially for barges launching, pull to shore, vessels' haul out and ship landing work. 2.Comparison with other Launch Way Rollers Bag is a innovative ship launching technology, comparing with "end-on launching", "side ship launching", "float-out". This ship launching technology overcomes the restrictions of fixed launching track of side-launch. Ship launching airbags are accepted by more and more shipyards world wide due to its advantages of saving time, saving investment, flexible, safety. The biggest vessel launched by ship launching airbags up to 100,000 DWT. 3.Material and constructure of Marine Airbag Inflatable Marine Airbags are to be constructed of an out rubber layer, multilayer heavy-duty synthetic-tire-cord layers, and an inner rubber layer vulcanized firmly. Ship launching marine airbags are cylindrical balloon body, with two conical head and end mouth. Air tightness swivel and air inlet kits are screwed with end mouth. Refer below picture. 2. The outer rubber layer covers the outside of ship launching marine 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. 4.Classification of Roller Marine Air Bags Ship launching marine airbags are categorized by "ordinary airbags", "high-bearing capacity airbags", and "Super-high-bearing capacity airbags" according to the bearing capacity. The standard diameter of ship launching marine airbags (D) varies such as 0.8m, 1.0m, 1.2m, 1.5m, 1.8m and 2.0m, 2.5 meters etc. The standard effective length of air bag (EL or L) is from 6m to 26m, which should be specified by the user. Other specification ship launching airbags also can be supplied upon request. 5.Performance Parameters of Offhshore marine ships pneumatic rubber airbag Prior to delivery of the ship launching marine airbags, we test every air bag .All Evergreen Maritime ship launching marine airbags are manufactured and tested comply with  ISO 14409 "Ships and marine technology - ship launching air bags certificated by CCS, LR, DNV. 6.examples of  marine ships pneumatic rubber airbag For more information,please contact me directly: Ratchet Tie Down,Cargo Straps,Retractable Ratchet Straps,Endless Ratchet Straps,Stainless Steel Ratchet Straps WINNERLIFTING SAFETY EQUIPMENT CO., LTD. , https://www.ratchetstrapfactory.com
1. Synthetic-tire-cord layer -Â Reinforcement layer of the ship launching marine 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. Buoder use the 1870 dtex/2 type synthetic-tire-cord fabric. The warp is over 95 cords per 100 mm in width, and the breaking strength is more than 310N per cord.
