Marine Rubber Floating Boat Docking Ship Launching Airbag
Product Introduction:
Ship launching airbags are known as roller bags, launching air
balloons, inflatable marine airbags, air lift bags, and salvage
bags. Ship launching airbags are specialized marine rubber air bags
that are used for launching marine vessels. ship landing or
haul-outs. Marine rubber airbags are also widely used in loading,
floating, lifting and moving sunken ships, and salvaging stranded
boats. Rubber airbags are made of heavy-duty synthetic-tire-cord
layers with inner and out rubber layers in a long cylindrical
balloon shape.
The advantageous to using this system over traditional ship
launching techniques
An marine airbag ship launching system does not need the
traditional fabricated slipway so it saves time, investment, land,
etc. Marine airbag need no extra maintenance and after use they can
be cleaned and folded in the corner to wait for another mission. It
is easy to find that airbags’ elasticity can give more protection
to the launched ship. A remarkable character of airbags is that the
working height can be changed to redirect the ship or object being
launched by adjusting the inner air pressure. For this character it
is peerless compared to traditional ship launching techniques.
Advantages of Shunhang Airbags
1. High Bearing Capacity
Inflatable rubber airbag’s main technical requirement is regulated
in CB/T 3795--1996 published by China State Shipbuilding
Corporation.
Henger adopts new rubber formula and high-strength enhanced
synthetic-tyre-cord layer, which improves the airbag’s bearing
capacity two times more than CB/T 3795--1996 standard.
The synthetic-tyre-cord layer of Henger marine airbag adopts dipped
Nylon-6 1400dtex/3-V2 tyre cord.
The strength & durability of airbag improves 20%, compared to
polyester tire cord which is widely used by friendly competitors.
2. High Kneading-resistance Capability
When the airbag is rolling under the ship bottom, it will suffer a
“kneading force” from ship bottom and ground because of not uniform
rolling speed, which could case problems like delamination, layer
buckling, etc.
Shunhang improved the manufacturing technique and raw material
formula to strengthen kneading-resistance capability of the airbag
and avoid worse accident .
3. New Anti-explosion Design of End Part
The possibility of air leakage in the joint area of metal part and
rubber part is also increasing as working pressure of airbag is
added. After using for times under high working pressure, the
airbag would burst and metal part would hurt workers.
Shunhang invented new anti-explosion design of the airbag end part,
increasing the bonding strength and air tightness between rubber
body part and end metal part. Shunhang airbag is working very well
under higher working pressure without potential safety hazard.
4. High strength galvanized anti-release structure
Casting metal part with chemlok coating.
chemlok coating strengthens the bonding between metal part and
rubber body after vulcanization.anti-release structure of the metal
part makes the connection more tight.

As a soft flexible body, airbag’s shape depends on various factors,
such as the shape of ship bottom, ramp shape, width of ship bottom,
length of airbag, position of airbag under the ship, etc.
Users should calculate the bearing capacity of airbags basing on
above factors, correct bearing capacity accordingly.

Formula: Bearing capacity F=PS
P=pressure in the airbag(MPa)
S=contacting area between ship bottom and airbag(M²)
S= π*(D1-D2)/2
