They call it the "jaws of life" I always think that' name is overdoing it. That's what the firemen and the EMS folks call them and you would, too, if they managed to rip you out of a smashed car with gasoline spilled all around you ready to ignite. And I imagine they do that a dozen times or more each day with the accident rate what it is. They take a special skill to use because under dire circumstances speed is of the essence. But placing them incorrectly can result in the patient being injured even more when the metal finally "gives" and tears apart. It would be great if someday you could just ask Google: How many people owe their lives to the 'jaws of life'? I'll bet it's enough to populate a small city, especially since modern cars are designed to give up energy in a collision by crushing. http://www.google.com/search?q=How+m...+of+life%27%3F Google's still got a ways to go . . . All that turned up the was remotely relevant was: https://www.flickr.com/photos/75797806@N00/209634792/ Pretty interesting stuff. Quick and powerful.. Capable of excerting 53,000 psi at the tips at 24 inches spread.. Barring unusual circumstances... A crew should be able to force all the doors, remove the roof, force the seats back, and lift the dash....in five to ten minutes. -- Bobby G. |

It would be great if someday you could just ask Google: The "Jaws of Life" was a trademark by Hurst Corp. which was developed and used in auto racing and crash extrication. It was heavy and vibrated like heck when run off the gas power pump, which was notoriously hard to start and required much maintenance. The motor noise and vibration would put victims into a panic state unless crews were well trained. One could pinch their finger off between the jaws when the jaws were let down. Later came electric pumps. It was a major advance over the porta power eq. mentioned. The porta power stuff was used in the construction industry and adapted by the fire service. The alligator jaws mentioned were very weak and if not operated correctly would break during an evolution. Very hard to pump and cheater bars were used sometimes. The pump had to be operated against a solid surface such as asphalt. They sometimes wouldn't work if the reservoir was above the pump. Also short hoses... Would NOT cut through the A pillar of a car. Now air bags have become common and useful. Gotta go... -- Tekkie *Please post a follow-up* |
