SYSTEM INSTALLATION:
Figure 1 shows a typical horizontal lifeline system installation. When using an energy absorbing lanyard to
connect to the system, the anchorages must be located at a height above the working level which will limit the
free fall to six feet. The length of the lanyard must be considered when determining the height of the anchorages.
When using a self retracting lifeline (SRL) to connect to the system, the end anchorages must be located above
the user. The SRL, when fully retracted, must be above the harness attachment level. The horizontal lifeline
system should be positioned at a level that will minimize free fall while allowing ease of use.
The horizontal lifeline should be positioned near the work location to minimize swing fall hazards. The connecting
subsystem length should be kept as short as possible to reduce the potential free fall and required clearance distance.
Both anchorages must be installed at approximately the same elevation, so that the horizontal lifeline system is
not sloped more than a 1:12 pitch (1 inch rise over a 12 inch run). The cable must be in a straight line; no curves
or turns are allowed in a Sayfline Multi-span Lifeline installation.
The installation process consists of 7 steps:
1. Determine the location of end anchors and intermediate brackets.
2. Determine the orientation of the intermediate brackets
3. Attach one end to its anchor point.
4. Install cable guides and Sayflink sleeves onto the cable.
5. Assemble intermediate brackets into their anchor points.
6. Unthread turnbuckle(s)
7. Attach the other cable end to its anchor point and tension the cable
The steps are described in detail below:
Step 1.
Determine the locations of the end anchorages and evaluate their strengths in accordance with section
2.4. Determine the number of intermediate brackets necessary for your application. There must be one
intermediate bracket for every 30 feet of cable for systems over 30 feet in length. Additional
intermediate brackets (Part No. 7608001) may be purchased from DBI/SALA. Use Figures 6 and 7 to
