The provided document is a supplemental instruction manual for a series of Sealed Self Retracting Lifelines (SRLs) manufactured by DBI-SALA. It updates and adds information to a main user instruction manual (5902122) for these devices, focusing on retrieval models and specific technical specifications.

Function Description:

The DBI-SALA Sealed Self Retracting Lifeline is a fall arrest device designed to protect a single user by automatically extending and retracting a lifeline as the user moves. In the event of a fall, the device locks, arresting the fall. Certain models (those with "RETRIEVAL" in their description) also incorporate a retrieval system, allowing for the raising or lowering of a fallen worker to safety. These retrieval models are not intended for work support or positioning, but specifically for rescue operations. The sealed design protects internal components from harsh environments, enhancing durability and reliability.

Important Technical Specifications:

The SRLs come in various configurations, primarily differing in lifeline material, length, and the inclusion of a retrieval system.

• Lifeline Materials: Available with 3/16 inch (5mm) diameter 7x19 galvanized steel wire rope or stainless steel wire rope. Some models also mention 1/4 inch (6.3mm) diameter 12 strand spectra rope, aramid rope, or vectran rope, though the specific models listed in this supplement primarily use wire rope.
• Lifeline Lengths (Working Range): Available in 15 ft and 30 ft lengths. The "Working Range" does not include an additional 2 ft of lifeline that may deploy in the event of a fall.
• Maximum Arresting Distance: 42 inches (1.1 m).
• Maximum Arresting Force: 900 lbs (4.0 kN).
• Anchorage Strength Requirement: 5000 LBS (22kN).
• Capacity: Single user only.
• Dimensions and Weight:
  • 15 ft models (e.g., 3400825, 3400826, 3400827): Approximately 10.2" x 7.6" x 4.3" and 12 lbs.
  • 30 ft models (e.g., 3400800, 3400801, 3400802): Approximately 11.5" x 9.4" x 5.4" and 19 lbs.
  • 30 ft retrieval models (e.g., 3400850, 3400851, 3400852): Approximately 11.5" x 9.4" x 8.8" and 23.6 lbs.
  • Model 3400853 (retrieval, with mounting bracket): Approximately 11.5" x 10.4" x 8.8" and 25.4 lbs.
• Retrieval System (for models 3400850-3400853):
  • Gear Ratio: 6.2:1.
  • Weight Lifted: 200 lbs (for 3400850, 3400851) or 310 lbs (for 3400852, 3400853).
  • Cranking Force: 8 lbs - 21 lbs (for 200 lbs lifted) or 12 lbs - 30 lbs (for 310 lbs lifted).
  • Minimum Load for Lowering/Paying Out Line: 75 lbs (33.9 kg).
  • Force to Operate Winch at Capacity: Up to 30 lbs.
  • Retrieval Overload Feature: Winches on these SRL models do not incorporate an overload clutch. Users must monitor the individual during retrieval to prevent them from becoming stuck and subjected to excessive force.
• Component Materials:
  • Cable Guide: Nylon.
  • Ratchet Ring: Stainless Steel.
  • Motor Spring: Stainless Steel.
  • Connecting Hook: Forged Alloy Steel or Stainless Steel.
  • Housing: Not explicitly stated in this supplement, but typically durable, sealed material.

Usage Features:

• Self-Retracting Lifeline: Automatically adjusts lifeline length, minimizing slack and free fall distance.
• Impact Indicator: A visible color band indicates if the device has experienced impact loading, signaling the need for removal from service and inspection.
• Self-Locking Snap Hook: Ensures secure connection to the harness.
• Retrieval System (Specific Models):
  • Activation: Involves rotating a locking screw, rotating out the retrieval handle, pulling and holding a shift knob, and pushing the crank arm into the engaged position.
  • Operation: Rotate the crank arm counterclockwise to raise, or crank counterclockwise first to release the fall arrest brake, then clockwise to lower.
  • Disengagement: Requires removing load, pulling the shift knob, pulling the crank arm out to the disengaged position, securing with the locking screw, and stowing the handle.
  • Caution: Stop cranking when the line is fully extended or retracted to prevent component damage.
• i-Safe Enabled: Contains an electronic tag readable by compatible readers for inspection logs, inventory management, and other safety information.

Maintenance Features:

• Pre-Use and Monthly Inspection: Users must inspect the device before each use and at least monthly, following the user manual's guidelines. This includes checking the locking and retraction functions, lifeline condition, connectors, housing, fasteners, label legibility, and any signs of damage or missing parts.
• Annual Inspection: A competent person must perform an inspection at least annually.
• Post-Fall Inspection: If the device arrests a fall, it must be removed from service for inspection.
• Retrieval Component Inspection Steps:
  • Inspect the retrieval arm for distortion or damage.
  • Ensure the retrieval handle rotates out and secures in the cranking position.
  • Verify the locking screw tightens completely.
  • Confirm the shift knob pulls out to the unlocked position and then releases, locking the crank arm in both engaged and disengaged positions.
  • Test retrieval mode with a 75 lb - 310 lb sandbag to ensure smooth operation, no movement when the handle is released, and an audible "clicking" sound when raising.
• Not User Repairable: The device is not designed for user repair.
• Labels: All labels (ID, Instruction, Winch Operating, RFID, Retrieval) must be securely attached and fully legible.
