heavy lifting marine airbag D1.5mxEL18m 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.  FAQ Q1:What's the material of your products?  A:Our raw material is natural rubber, and rubber-dipped nylon cord fabric  Q2:Are you factory or trading company?  A:We are the company and factory,located in Jimo City,Qingdao,near to Qingdao port and Qingdao airport,which is convenient for transportation.  Q3:Can you do OEM?  A:Yes,we can do.As long as receive your request,we could produce accordingly.  Q4:What's your delivery time and payment terms?  A:Delivery time is according to customers' size and order qty.The payment terms you could choose are T/T,L/C at sight,Western Union and so on.  Q5:How can I get samples from you?  A:We are honored to provide you samples for check quality.Customers just confirm freight collect and then we could send out the sample by FedEx,DHL,UPS,TNT and so on.  Q6:What's certificates can your company provide?  A:We can provide CCS,ABS,DNV,LR,BV certificates.  Q7:What about your warranty time?  A:Our warranty period is 18 months.During this time,any problems about products from our factory,we solemn promise to change and repair them for free;if problems from customers' improper operating,we could provide free guidance and repair materials.

Brief Introduction & Working Principle
when compressed air enter into the vacuum pump, simultaneously under the push of air cylinder, the empty door of hopper will be closed and the vacuum will be formed in the hopper. The vacuum feeding machine forms air stream under vacuum state. Under the action of this air steam the material which is conveyed will be transported to vacuum hopper through hose. Certain time later (feeding time, adjustable), the compressed air is closed, the pneumatic vacuum pump is unable to produce vacuum, simultaneously under the push of air cylinder the emptying door of hopper will be opened and the vacuum will be disappeared in the vacuum feeder. The material will be fed into receiving equipment from the emptying door (for example tablet press, packing machine and so on), simultaneously, compressed air that stores up in air packet's blowback the filter, and the filter cleans by itself. Certain time late (discharging time, adjustable), the compressed air starts again. Move in cycles, the material is fed into the equipment continuously.
The machine is well designed and produced, consisted of vacuum pump (non-oil & non-water), stainless-steel-made product sucking mouth, feeding tube, cloth filter (or 316 stainless steel filter), vibration cleaner (or compressed air blower), vacuum product hopper and product level control system. There are some different between when machine combined with packaging machine, pellet pressing machine and Mixing Machine respectively.

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.
