3.0 INSTALLATION
3M Engineered System Installation: The 8mm HLL Permanent Horizontal Lifeline is an Engineered HLL System
designed, analyzed, and specifi ed by a 3M Certifi ed Installer for a specifi c location and product application. Installation
of the 8mm HLL System must be supervised by the 3M Certifi ed Installer. Changes in system location, equipment
placement, etc. will require review and revision of original specifi cations. Contact the Certifi ed Installer or 3M Fall
Protection for assistance.
Installation procedure will vary with the application and location of the 8mm Permanent Horizontal Lifeline (HLL), but
basic steps for installing the 8mm HLL are as follows:
1. Mount End Anchor Brackets, Intermediate Brackets, and Corner Brackets at the planned locations.
2. Starting at the entrance point to the system, thread the Cable Lifeline through all Intermediate Brackets and Corner
Brackets.
3. At the entrance point to the system, terminate the end of the Cable Lifeline with the planned End Connector and
Energy Absorber (if needed at each end of the lifeline) and connect the Cable Lifeline to the End Anchor Bracket.
4. If the HLL system requires Overhead Travelers, thread all Overhead Travelers on the free end of the Cable Lifeline.
Detachable Travelers can be installed by the User prior to use of the system.
5. At the far end of the system: connect the planned Energy Absorber and Pass Through End Connector to the End
Anchor Bracket, thread the Cable Lifeline through the Pass Through End Connector, tension the Cable Lifeline, and
then swage the Pass Through End Connector onto the cable with a Hex Swager.
6. Inspect all system swages.
7. Complete and Install the System Label at the entrance point to the system.
The proceeding sections detail installation of the components specifi ed in Table 1. Additional information is available in the
8mm Permanent Horizontal Lifeline Technical Data Sheets.
3.1 END ANCHOR BRACKETS: Minimum Grade A4-70 M16 (or 5/8 in) Fasteners should be used to mount End Anchor
Brackets to structure at a recommended torque of 50 Nm (37 ft-lbf). Mounting must support at least twice the load
values stated in the technical report generated by the 3M DBI-SALA Installed Systems Calculation Software for the system
layout, components, number of users, and SRL or Lanyard connecting device. Mounting orientations and installation are
as follows:
