DBI-SALA Rollgliss R550 Rescue and Descent Device (100m) | 3M 337325



Key Features & Benefits

  • Integrated dual-brake controlled-descent system ensures safe, smooth lowering of one or two users without manual rope control.
  • Bi-directional lifeline hub allows descent from either side, enabling immediate reuse after a descent or rescue operation.
  • 3/8 in (9.5 mm) static kernmantle rope provides high tensile strength and durability under heavy loads.
  • Compact aluminium housing and lightweight design for portability and ease of deployment on towers, cranes, structures or confined work areas.

Supports evacuation, rescue lowering or assisted-lifting with rescue wheel or drill-adapter option — versatile for emergency retrieval or planned descent operations.

×
  • Automatic controlled descent: The R550 device uses an internal dual-brake system to automatically regulate descent speed, eliminating manual rope control and ensuring safe lowering.
  • Bi-directional lifeline hub: Rope can descend from either side, enabling immediate reuse after a rescue or descent — ideal for multi-stage evacuations or repeated rescues.
  • Durable static kernmantle rope: The 3/8 in (9.5 mm) rope is engineered for strength and longevity under heavy loads, offering dependable performance in demanding industrial conditions.
  • Compact, lightweight housing: Aluminium alloy housing reduces overall weight while delivering robustness, enabling easy transport and installation on towers, cranes, or confined-space access points.
  • Versatile rescue & evacuation mode: Supports both emergency evacuation and assisted-lift rescue (with optional rescue wheel or drill-adapter), making it suitable for varied height-access and rescue scenarios.
  • Telecommunications / Telecom Towers: Safe evacuation or rescue of maintenance personnel from towers, masts or elevated platforms.
  • Wind Energy / Wind Turbine Maintenance: Rapid descent or rescue from nacelles or turbine towers during maintenance or emergency scenarios.
  • Construction & Infrastructure: Emergency escape or controlled descent from scaffolding, tall structures, or elevated work sites.
  • Oil & Gas / Petrochemical: Rescue or evacuation from elevated rigs, platforms, or confined high-access zones.

FAQs

What is the maximum descent height with the R550 100 m device? ⌄

The device supports descent (or rescue) up to 500 m (1,640 ft) for one user (max 310 lb / 141 kg), if rope length and configuration permit.

Can R550 support two persons at once? ⌄

Yes — up to two persons simultaneously, with combined weight not exceeding 620 lb (282 kg), subject to height/rope-length limitations.

What type of rope does the device use? ⌄

It uses a 3/8 in (9.5 mm) static kernmantle rope with braided polyester cover and nylon filament core, designed for durability and rescue loads.

Is user lifting (raising) possible or only descent? ⌄

Yes — the R550 can perform assisted-lift rescue if equipped with a rescue wheel or drill adapter, providing mechanical lifting capability.

What standards does this rescue device comply with? ⌄

The R550 is compliant with ANSI Z359.4, OSHA 1910.66, OSHA 1926.502, and CSA Z259.2.3-12 (depending on market/variant).

Is the system re-usable after a descent or rescue? ⌄

Yes — thanks to the bi-directional lifeline hub, rope can be rewound and device re-used, but cumulative descent energy and number of descents must be within manufacturer-specified limits.
