3M introduces the DBI-SALA Rollgliss R520 rescue and escape device, a new range of twin brake rescue and escape descenders.
A state-of-the-art, easy-to-use fully automatic controlled descent device, the DBI-SALA Rollgliss rescue and escape device features a dual braking system that offers a higher degree of safety during use. This rescue device, unlike friction based descenders provides controlled descent self-rescue regardless of the user’s weight for the evacuation of multiple personnel, or the versatility of assisted rescue.
According to Rick Millar, Technical Manager for 3M Australia & New Zealand, the R520 rescue and escape device sets new standards in performance, rescue and safety. For instance, should one of the brake systems fail due to damage or wear, the second brake provides increased protection by holding the load safely and supporting the person to the ground.
The user simply connects the descender to an anchorage point, attaches the connector to their harness and lowers themselves to perform a hands-free descent. The descent speed is automatically limited during the descent, adjusting to the user’s body weight, and allowing for a secure and effective escape within seconds.
The system is ideal for use in a number of industries including utilities, construction and maintenance, fire and emergency services as well as general industry.
