The equipment used by trench rescue, structural collapse, and urban search and rescue (USAR) teams sometimes crosses into what firefighters usually find on rescues and pumpers but more often is specialized equipment designed for a single purpose.
Equipment used by these teams is typically unique to the types of jobs team members must perform to achieve their objectives in what is often characterized as technical rescue.

Struts
Tom Gavin, national sales manager for Paratech, says the products his company makes that are most often used in USAR, building collapse, and trench rescue situations are its air bags and its multipurpose struts. “With the struts, which use a thread system instead of a pin, you can change the heads to use the struts for a different type of use,” Gavin says. “You change the head for the discipline-from walls and concrete slabs and trenches to buses, trucks, and cars.”
Gavin points out that Paratech’s gray struts will hold up to 80,000 pounds for a four-foot-long strut, while its gold struts, which are 3½ inches in diameter, can hold 80,000 pounds at eight feet long. “Most fire departments start out with the gray struts, which are sold in our highway vehicle stabilization kits,” he says. “When they want to go really big, they add the gold struts. When you get into USAR and Federal Emergency Management Agency (FEMA) teams, they use quite a lot of gold struts, along with our Raker system.”
Gavin notes that Paratech’s gray struts can telescope out to 11 feet, while gold struts telescope to 18 feet. “The gray base plates we make fit both gray and gold struts, but we also make gold base plates for heavy rigging jobs and high angle rescue.”

Hurst Jaws of Life makes the Airshore series of rescue struts and equipment used in USAR, structural collapse, and trench rescue situations. Airshore Pneumatic Rescue Struts are made in extendable lengths from one foot to eight feet that extend from 1½ feet to 12 feet. Capacities range from 20,000 to 30,000 pounds, depending on the strut.
Hurst also makes the Airshore Rescue Tool Gantry/A-Frame in sizes from 4½ to 12 feet, the Airshore Rescue Tool Column in sizes extendable from two feet to 12 feet and carrying a maximum capacity of 85,000 pounds for the two-foot model, and various Raker Rail assemblies.
Chris Pasto, founder and owner of Res-Q-Jack, says that “no matter which strut you’re using for an application, you have to know the load you’re working with and the capacity of the strut that you’re using. Also, you shouldn’t limit your thinking in applying struts be
