Product Description

Layers: 6-8 Layers Rubber: Natural Raw Rubber Certification: BV, ISO9001, CCS Specification: ISO14409: 2011, LR, BV, DNV, CCS, ABS HS Code: 40169500 Diameters: 0.8m-2m Usage: Ship Launching, Landing, Upgrading, Lifting Trademark: Evergreen Maritime Origin: China Introduction and Achievement

Evergreen is the inventor of first lift balloon, and sets the standard in the industry for high performance and usage technology. Now, Evergreen boat balloon, are widely used in ship launching and landing, sunken ships salvage and refloatation, heavy lifting and conveying.

This is one great ship launching ways Ship launching or upgrading relying on lift balloon, is a innovative technology having utmost developmental prospect in shipbuilding. Boat balloon, overcomes the disadvantage of fixed launching track by which The productive abilities of shipbuilding and ship repair were limited in the small and medium sized shipyards. Now it has become a Flexible Launching Technology full of mobility, having advantages in saving effort, saving time, Saving work load, saving investment, flexibility, safety, reliability, outstanding comprehensive economy benefit, flexible, safe, reliable, and outstanding benefit, etc. The launching technology of apply lift balloon, to the Launching and landing of ships overcomes the restrictions of traditional slide board technology which is commonly used in building small or medium size ships.

Construction Features of lift balloon,:

Lift balloon, basic body consists of which consist of our rubber layers, synthetic-cord-reinforced rubber layers, are kind of a cylindrical airbags with hemispherical heads at the both ends.
All of these are vulcanized together, and then compress air inside to enable in to roll.

1. Outer Rubber
The outer rubber layer that covers the outside of lift balloon, protect 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.

2. Synthetic-tyre-cord layer for reinforcement
The reinforcement cord layers of lift balloon, which are made of Synthetic-tire-cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and to distribute The stress evenly providing strong efficient reinforcement.
(To know the detailed technology parameter, please refer Material Selection. )

3. End Fittings
End fittings of boat balloon, include air tightness swivel and airbags safety air inlet.

Classification of lift balloon:

1. The standard specification of lift balloon

You can choose the required diameter and effective length to meet your projects.
L Diameter (D): Its from 0.8m to 2.0m.
L Effective Length (EL): Its from 6m to 18m.
L Total Length (TL): Its from 7m to 19.5m
The above specification only is our standard specification arrange. Other specification boat balloon, also can be supplied upon clients request.

2. The standard number of layers of lift balloon
We define the number of layer, which means the number of Synthetic-tyre-cord layer, in order to confirm the Safety Working Pressure. Normally, Ship Launching Airbag Include 4, 5, 6, 7, 8 layers types. Other type is available upon clients request.

3. The material of lift balloon,
There're two kinds of synthetic-tire-cord because of the different performance.

Lift balloon Unit 1400 dtex/21870 dtex/2
Break Strength N/ strand ≥ 215.6 ≥ 284.2
Diameter mm 0.65 ± 0.05 0.74 ± 0, 05
Adhesion Strength N/cm ≤ 137.2 ≤ 156.8

4. Our lift balloon, is also known as:
Lift Balloon for upgrading and conveying
Lift Balloo for hoisting and transporting heavy structure
Lift Balloo for refloatation, salvaging sunken ship or heavy immersed steelstructure
Lift Balloo for erecting floating bridge or pipeline
Lift Balloo for caisson moving
