RMRG tests rescue systems and components as part of our ongoing equipment development and safety assurance work. We have a long history of this due to our close ties to the University of Colorado and the many engineers that become members of RMRG.

Test Tower

RMRG owns and operates a 35 ft. test tower. This allows for both static and dynamic testing with drop mass up to 1000 lbs. We have developed protocols for drop load testing and abrasion testing. The test tower is equipped with a high speed data acquisition system including two load cell strain gauges. Some of our results:

We performed an extensive investigation of a June 22, 2010 climbing accident fatality in Eldorado Canyon caused by a climbing rope failure, Yellow Spur Rope Failure Investigation.

Three of our members published some of our results, "On the Utility of Rescue Randy Mannequins in Rescue Systems Drop Testing" (700 KB, 18 pages) at the 2009 International Technical Rescue Symposium (ITRS).

RMRG acknowledges Honeywell/Sensotec and National Instruments for their generous support of our research activities. National Instruments' web site features a case study of RMRG's application of National Instruments' products.

In the course of our relationship with National Instruments, we prepared RMRG Equipment Testing Program and Test Tower Facility (15pp, 3 MB PDF), a historical summary through 2007 of some of our rope and radio direction finding testing efforts.

Safety Assurance

RMRG typically tests all our equipment to ensure our 4:1 safety factor for individual components. Rescue operations and our testing involve both static and dynamic loads. Testing also helps ensure that the equipment we use has an adequate durability.

Equipment Development

We use as much commercial rescue equipment as possible. In some cases, there is not a commercial product available that meets our rescue requirements. In these cases we will develop our own equipment. If you have a question about our equipment development work, please contact our equipment chair at . The following pieces of equipment have been developed by RMRG.

Backpackable stainless steel litter with metal wall plates.

Litter helmet
Modified fire helmet with retractable shield and litter helmet rail attachment system.

Brake Plate
Litter Belay device that can be configured for single rope scree or double rope vertical rescue lowering.

Cable Winch
Portable gas powered hydraulic winch for raising or lowering 3/16" aircraft cable to 1000 lbs. RMRG retired the winch system in 1999.

Downed Aircraft Locator Antenna
Portable antenna for locating downed aircraft ELT signals
