The Rollgliss R550 offers the choice of controlled descent rescue, evacuation or the versatility of assisted rescue with lifting capabilities. This state-of-the-art, fully automatic controlled descent device can be used for rescue and evacuation from heights up to 1,640 ft (500m) for one user at 310 lbs (141kg) or 575 ft (175m) for two users totaling 620 lbs (282kg). It features 3/8" (9.5mm) super static kernmantle rope, and is configured with connecting hardware at each end of the lifeline to operate in both directions. During assisted-rescue scenarios, a fallen worker can be attached to the R550 device, raised to a point that allows their fall arrest device to be removed, then lowered to the ground safely. Remember, during an emergency every second counts! You can count-on and trust the DBI-SALA Rollgliss systems, in use all over the world; Wind Turbine Construction & Maintenance, Utility Pole/Tower Construction & Maintenance, Fire & Emergency Rescue Services, Commercial Construction Sites, Industry and MRO Facilities, Government & Military Operations and more!
