Search-and-rescue operations in an urban environment present a unique challenge. The days of using jacks to lift vehicles and chunks of concrete off an injured person are long gone. These days, USAR teams use airbag lifting systems to do the job. The flat Kevlar bags are inserted under the heavy object and inflated with an air pump.
The largest deluxe bag systems are capable of lifting as much as 70 tons 20 inches off the ground at full inflation. In addition to the lifters, shoring equipment is necessary to make sure the passageways the teams create are stable and safe to travel into.
