Incredible airbag jacks!How did it save countless rollover vehicles?

The truck was driving on the road in a good manner, but the painting style gradually began to change, and I saw it swaying from side to side, and finally it turned over directly.

However, there are not a few accidents like this type of vehicle rollover. Poor speed control, complex road conditions, bad weather, and overly worn tires can all cause a vehicle to roll over.

Usually, for some cars, several people can work together to lift it up and right. But for large trucks and trucks, cranes are needed to straighten them. However, the force of the crane is uncontrollable, and it is easy to cause secondary damage to the vehicle.

As a result, there was a type of balloon jack called the Catchbag.

It has a very simple structure, a bag connected to an inflatable hose. Place it on the side of the underside of the overturned vehicle and inflate the interior with a high-horsepower air pump. Once inflated, the crane will pull the vehicle over towards the Catchbag. At this point, the airbag catches the vehicle and provides it with support, while the air inside acts as a cushion to ensure that the vehicle does not come into direct contact with the ground.

Once the vehicle is righted, the Catchbag can begin to deflate in place. Using this method to righten the vehicle not only increases the rescue speed, but also saves the maintenance cost of the vehicle, which is an artifact that can be popularized.

Perhaps in most people's impressions, the airbag jack is mainly used to raise the bottom of the car and repair the vehicle. But in fact, its principle is also done by inflating.

Balloon jacks are also called pneumatic jacks, and common airbags are single-layer, double-layer and three-layer. When in use, a 5-8 kg pressure air compressor will be used to inflate and jack the vehicle. Its light weight, large lifting tonnage and other characteristics, is widely used in the maintenance of the transportation industry.

However, industrial airbags do much more than that.

Newly built ships are also inseparable from the assistance of airbags when they are launched. The ship airbag upper discharge process refers to the method by which the ship is launched through the airbag. It works by using the air pressure difference to fill the inside of the airbag with gas, so that a certain pressure is generated on the outside of the airbag and the ship is rolled into the water. This method is simple and inexpensive.

And when it comes to ship rescue, airbags also play a key role. When a wrecked ship is submerged, the hull can be lifted and towed to a safe position using an airbag. Not only that, but the trapped people can also escape through the airbag, which is equivalent to a lifebuoy.

The technology of launching ships using airbags is an innovative design with independent intellectual property rights of the mainland. In addition, it has been widely promoted around the world. At present, airbags have been widely used in the jacking and transfer of caissons in port construction, as well as shipwreck salvage, underwater installation engineering and other fields.
