The Air Force X-1 has been designed to military specifications.The X-1 bag is capable of lifting up to 5 tonnes on its own or 10 tonnes when used in pairs. The X-1 lifting bag is relatively low pressure (Working pressure is 2 bar with a bursting pressure of over 4.5 bar) which means its soft footprint enables you to lift objects on soft ground such as snow, sand or ice. It exerts a soft force against the load, preventing damage to vulnerable structures. The lifting surfaces are extremely strong and durable, it can be inflated over broken glass or other sharp hazards. The video below explains more about the X-1 and shows real life practice scenarios such as a trapped victim extraction.
