PRODUCT DESCRIPTION:

Figure 1 illustrates the 3M™ DBI-SALA
system designed to be installed overhead on the bottom flange of a beam and to roll along a horizontal beam.
Figure 2 illustrates components of the Trolley Anchor. See Table 1 for Component Specifications. The Trolley Anchor is comprised
of two Side Plates (A). The Load Bar (B) that connects the Side Plates adjusts to various beam flange widths with Adjuster Dials
(C) built into the outside of each Side Plate. The Side Plates can be adjusted by removing the Pull Ring (H) and Clevis Pin (G)
and then reinstalling. The four Wheels (D) are intended to roll smoothly along the beam, aided by Bearings (E). The Fall Arrest
subsystem connects to the Connector Ring (F) in the center of the Load Bar. A typical Fall Arrest system consists of a Fully Body
Harness and an Energy-Absorbing Lanyard or Self-Retracting Device (SRD).
System Specifications:
Capacity: One person with a combined weight (clothing, tools, etc.) of no more than 310 lb. (140 kg) for ANSI, or no more
than 420 lb. (191 kg) for OSHA.
Anchorage The structure to which the anchorage connector is mounted must be capable of sustaining force in the anticipated
Strength: directions of loading. See Section 2.1 for values.
Only one Fall Arrest system may be attached to an individual Trolley Anchor at a time. The trolley may be used on
beam flanges 3.0 in. to 8.0 in. (7.6 cm to 20.3 cm) wide and up to 11/16 in. (1.75 cm) thick. The minimum radius the
trolley can follow is 48 in. (122 cm). The beam structure must meet the strength requirements specified in this section.
The beam must be horizontal and level.
