The working principle of the Ship Heavy Lifting Airbags "roller" is almost the same as that of drum hauling heavy objects. Place the airbag between the bottom of the weight and the ground, and then inflate the caisson, pull the weight by external force to roll the airbag, and drive the weight to move.
The principle of ship airbag hauling
The working principle of the Ship Heavy Lifting Airbags "roller" is almost the same as that of drum hauling heavy objects. Place the airbag between the bottom of the weight and the ground, and then inflate the caisson, pull the weight by external force to roll the airbag, and drive the weight to move. Compared with traditional rollers, the airbag will deform more under the weight of the caisson. Increase the contact area between the airbag and the ground, thereby reducing the pressure per unit area, the force is uniform, and the adaptability to the scene is strong.
Marine Airbag Rollers Technical Requirement
According to CB/T 3795-1996, marine airbags need to meet the following requirements.
1. Size error
Diameter and effective length error: ±2%
Total length deviation: ±4%
2. Elastic deformation: Under 1.2 times of working pressure, the diameter deformation is less than 5%.
3. Safety factor:> 4.5
4. Air tightness: pressure drop <5% after 1 hour of inflation
5. Surface quality: streamlined, no cracks, no bubbles, no double skin, no impurities, no obvious defects such as obvious dirt.
6. Explosion-proof design at the end.
Product Introduction of Lifting Marine Airbags
Ship heavy lifting airbag
Other names are Ship Heavy Lifting Airbags, ship airbags, ship launching airbags, ship rescue airbags, ship rescue airbags, inflatable airbags, ship lifting airbags, airbags, which are made of rubber and multilayer dipped tire fabric.
Ship heavy lifting airbags are widely used in disembarking/landing ships/ships/ships, lifting and carrying heavy objects, and rescuing stranded ships.
Marine lifting airbags are now very popular among shipyards, shipowners and marine material companies.

Product Advantage
1. High Kneading-resistance Capability
When the airbag rolls under the bottom of the ship, the rolling speed may be uneven, so the bottom of the ship and the ground will be subjected to "kneading force", which may cause problems such as delamination and buckling.In response to this problem, Henger has improved the manufacturing process and raw material formula of the airbag, enhanced the anti-kneading ability of the airbag, and avoided more serious accidents.We coat each layer of the airbag with a specially formulated adhesive to dissolve dust and impurities.Specially formulated slime
Through this measure, the adhesion between the layers is further improved to ensure air tightness.
2. New Anti-explosion Design of End Part
As the working pressure of the Ship Heavy Lifting Airbags increases, the possibility of air leakage in the joint area also increases. After several times of use under high working pressure, the airbag may rupture and the metal parts may injure workers.
In response to this phenomenon, Henger invented a new explosion-proof design for the end of the airbag, thereby improving the bonding strength and airtightness between the main part of the rubber and the metal part of the end, and reducing the occurrence of dangerous accidents.
High strength galvanized anti-release structure
We will cast metal parts with chemlok coating.
The coating not only enhances the bonding force between the metal parts and the rubber body after vulcanization, but also makes the anti-release structure to make the connection closer.
