It may be difficult for disaster relief rescuers to enter disaster-stricken areas with large-scale equipment. As such, the first batch of emergency relief workers are usually required to enter the disaster area on foot to prevent delays in rescue. However, this also means that they are not able to carry equipment that is too heavy, and without the larger equipment, it is difficult to rescue the victims under the rubble.
Borrowing the idea from automobile safety air bags, the air bag of this Handheld Air Bag Jack can be used to support the heavy weight of debris without using large machinery, thus achieving rapid relief for victims at least in the more shallow layers of the debris. When not in use, the air bag wraps around the handle for convenient storage and the user will need to unlock the button and expand it to start using. Simply unlock the button and the air bag will emerge in a half-folded state. Fully expanded, it grows into the size of a pillow, but can easily jack tons of weight.
When the gas’s pressure from a linked gas tank is too large, the LED light on the switch will changed from blue to yellow to attract attention. The red scale on the barometer will also indicate that the gas pressure is too large and dangerous. The sensor is equipped with a battery, which is responsible for the overall power supply. This gas pipe interface has a metal card slot, which fits the air bag interface perfectly.
Handheld Air Bag Jack is designed for earthquake relief. To assist disaster relief, it supports the heavy weight of ruins without the need for large machinery, which can result in a faster relief time for victims in the shallow debris layers.
