3.1 PLANNING: Plan your Fall Protection system prior to installation of the Trolley Anchor. Account for all factors that may
affect your safety before, during, and after a fall. Consider all requirements, limitations, and specifications defined in
Section 2 and Table 1.
;
3M shall make available upon request information that is necessary for the design and planning of systems.
3.2 SELECTING AN ANCHORAGE BEAM: The Trolley Anchor may be installed on horizontal and level beams meeting the
anchorage requirements specified in Table 1. The beam must have End Stops (A) at each end to prevent the trolley from
rolling off the beam. See Figure 10 for reference. The end stops must be sized and positioned such that they are able to
safely stop the trolley. The trolley should not catch or hang on the end stop; the trolley must be able to freely return in
the opposite direction after touching the end stop.
;
Joints between beam sections must be flush to allow the Trolley Anchor to pass over smoothly.
3.3 INSTALLING THE TROLLEy ANCHOR: The Trolley Anchor can be installed on beams meeting the anchorage
requirements specified in Table 1. See Figure 1 for the Beam Trolley measurements. Figure 7 illustrates installation of the
Trolley Anchor. To install the Trolley Anchor:
1. Measure the beam flange width to determine the Adjustment Hole settings on the Trolley. Figure 7.1 and Table 2
illustrate the hole positions on the left and right Adjuster Dials and the Load Bar that correspond with Table 2. Record
these Adjustment Hole settings and use them for Step 3 and 4.
2. To open one side of the trolley, remove the Pull Ring from the Clevis Pin and pull the Clevis Pin up out of the Adjuster
Dial. Slide the Side Plate off the Load Bar.
3. On the still assembled side of the Trolley, remove the Pull Ring and Clevis Pin from the Side Plate, and adjust the
width to the required Adjustment Hole settings determined in Step 1 and from Table 2. Lock the adjustment into
place by re-installing the Clevis Pin vertically with the Clevis Pin Head on top through the appropriate Adjustment Dial
and Load Bar holes and installing the Pull Ring.
4. Place the partially assembled Side Plate and Load Bar onto the bottom flange of the beam with the Connector Ring
hanging down. Slide the un-assembled Side Plate onto the Load Bar and align with the required Adjuster Dial and
Load Bar holes as determined in Step 1. Install a Clevis Pin vertically, with the Clevis Pin head on top, through the
Adjuster Dial and Load Bar holes and secure with the Pull Ring.
;
Trolley width settings specified in Table 2 must be followed. Adjustments on the Load Bar must use the same
setting on both sides (e.g. A - A, B - B, etc.). Adjustments on the Adjuster Dial must be within one unit. Failure to
use correct settings may improperly load the Trolley. If the beam flange is too wide to install the Clevis Pin through
the correct holes, adjust the Trolley to the next larger beam flange size as specified in Table 2. The D-Ring must
always be centered between the two Side Plates.
5. Confirm the distance from the Trolley Wheel face (C) to the edge of the beam flange (D) is no more than 1/16 in.
(1.6 mm). If the distance is greater than 1/16 in. (1.6 mm), change the Adjuster Dials to the next narrower setting in
Table 2. Also, visually confirm the Clevis Pins (A) are installed with the pin heads on top of the Adjuster Dials and that
the Pull Rings (B) are fully installed through the Clevis Pin holes.
;
If the trolley is moved to another beam, or if the Pull Rings are removed, the circle type pull rings are reusable.
If a cotter pin is used, a new cotter pin is to be used for each new installation. Use 5/64 x 3/4", 18-8 stainless
steel Pull Rings or Pivot Point bow-tie™ clip Pull Rings. If you are using Pivot Point bow-tie™ clips, they are also
reusable. Only use the original clevis pins. Do not make substitutes.
4.0 USE
4.1 BEFORE EACH USE: Verify that your work area and Fall Arrest system meet all criteria defined in these instructions.
Verify that a formal Rescue Plan is in place. Inspect the product per the 'User' inspection points defined in the "Inspection
and Maintenance Log". If inspection reveals an unsafe or defective condition, or if there is any doubt about its condition
for safe use, remove the product from service immediately. Clearly tag it "DO NOT USE". See Section 5 for more
information.
4.2 FALL ARREST CONNECTIONS: The Trolley Anchor is used with a Full Body Harness and Energy Absorbing Lanyard or
Self-Retracting Device (SRD). Figure 9 illustrates connection of the Lanyard (A) or SRD (B) between the Harness and
Trolley Anchor. Connect the Lanyard or SRD between the D-Ring on the Trolley Anchor and the back Dorsal D-Ring on the
Harness as instructed in the instructions included with the Lanyard or SRD.
;
Horizontal Lifeline Connections: The Beam Trolley Anchor cannot be used as an end anchor point for a
Horizontal Lifeline (HLL).
1 Qualified Person:
An individual with a recognized degree or professional certificate, and extensive experience in Fall Protection. This individual must be capable
of design, analysis, evaluation, and specification in Fall Protection.
2 Competent Person:
One who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazard-
ous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.
