1.0 APPLICATIONS

1.1 PURPOSE: The Trolley Anchorage Connector is designed to move along horizontal beams with an attached
personal fall arrest system. This trolley is to be used only as a component of a personal fall arrest system.
Do not hang, lift, or support tools or equipment from the trolley.

A. FALL ARREST: The trolley is used as a component of a personal fall arrest system. Personal fall arrest

systems typically include a self retracting lifeline, connector to attach the self retracting lifeline to the
trolley, and full body harness. A personal fall arrest system is used where a free fall is possible before
the fall is arrested.

1.2 LIMITATIONS: Consider the following application limitations before using this equipment:

A. BEAMS: The trolley may be used on beam flanges 3 in. (7.6 cm) to 8 in. ( 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 section 2.4. The beam must be horizontal and level.

B. CAPACITY: The trolley is designed for use by persons with a combined weight (clothing, tools, etc.) of no

more than 310 lbs (141 kg). Only one personal fall arrest system may be connected to a single trolley.

C. PERSONAL FALL ARREST SYSTEM: Personal fall arrest systems used with the trolley must meet the

system requirements as specified in section 2.5.

D. FREE FALL: Personal fall arrest systems used with the trolley must be rigged to limit the free fall to

6 feet. See subsystem manufacturer’s instructions for more information.

E. FALL CLEARANCE: There must be sufficient clearance below the user to arrest a fall before the user

strikes the ground or other obstruction. The clearance required is dependent on the following factors:

• Elevation of Trolley • Connecting subsystem length

• Deceleration distance • Movement of harness attachment element

• Worker height • Free fall distance

See personal fall arrest system manufacturer’s instructions for more information.

2.0 SYSTEM REQUIREMENTS

2.1 COMPATIBILITY OF COMPONENTS: DBI-SALA equipment is designed for use with DBI-SALA approved
components and subsystems only. Substitutions or replacements made with non-approved components
or subsystems may jeopardize compatibility of equipment and may affect the safety and reliability of the
complete system.

2.2 COMPATIBILITY OF CONNECTORS: Connectors are considered to be compatible with connecting
elements when they have been designed to work together in such a way that their sizes and shapes do
not cause their gate mechanisms to inadvertently open regardless of how they become oriented. Contact
DBI-SALA if you have any questions about compatibility.

Connectors (hooks, carabiners, and D-rings) must be capable of supporting at least 5,000 lbs. (22.2kN).

Connectors must be compatible with the anchorage or other system components. Do not use equipment
that is not compatible. Non-compatible connectors may unintentionally disengage. See Figure 3. Connectors
must be compatible in size, shape, and strength. Self locking snap hooks and carabiners are required by
ANSI Z359.1 and OSHA, and in Canada, by CSA Z259.12.

2.3 MAKING CONNECTIONS: Only use self-locking snap hooks and carabiners with this equipment. Only use
connectors that are suitable to each application. Ensure all connections are compatible in size, shape and
strength. Do not use equipment that is not compatible. Ensure all connectors are fully closed and locked.

DBI-SALA connectors (snap hooks and carabiners) are designed to be used only as specifi ed in each

product’s user’s instructions. See Figure 4 for inappropriate connections. DBI-SALA snap hooks and
carabiners should not be connected:

A. To a D-ring to which another connector is attached.

B. In a manner that would result in a load on the gate.

NOTE: Large throat snap
in a load on the gate if the hook or D-ring twists or rotates. Large throat snap

hooks should not be connected

as rebar or cross members that are not shaped in a way that can capture the gate of the

to standard size D-rings or similar objects which will result

C. In a false engagement, where features that protrude from the snap hook or carabiner catch on the

anchor and without visual confirmation seems to be fully engaged to the anchor point.

D. To each other.

E. Directly to webbing or rope lanyard or tie-back (unless the manufacturer’s instructions for both the

lanyard and connector specifically allow such a connection).

F. To any object which is shaped or dimensioned such that the snap hook or carabiner will not close and

lock, or that roll-out could occur.

G. In a manner that does not allow the connector to align properly while under load.

Figure 3 - Unintentional Disengagement Figure 4 - Inappropriate Connections

If the connecting element to which a snap hook (shown) or carabiner attaches
is undersized or irregular in shape, a situation could occur where the connecting
element applies a force to the gate of the snap hook or carabiner. This force may
cause the gate (of either a self-locking or a non-locking snap hook) to open,
allowing the snap hook or carabiner to disengage from the connecting point.

2.4 ANCHORAGE STRUCTURE STRENGTH: The structure to which the trolley is installed must sustain static
loads in the directions permitted by the personal fall arrest system of at least 5,000 lbs. (22.2 kN) When
more than one trolley is installed on the same anchorage structure, the anchorage structure strength must
be multiplied by the number of personal fall arrest systems attached to the structure.

From OSHA 1926.500 and 1910.66: Anchorages used for attachment of a personal fall arrest system shall

be independent of any anchorage being used to support or suspend platforms, and must support at least
5,000 lbs. (22.2 kN) per user attached; or be designed, installed, and used as part of a complete personal
fall arrest system which maintains a safety factor of at least two, and is supervised by a qualifi ed person.

2.5 PERSONAL FALL ARREST SYSTEM: Personal fall arrest systems used with this equipment must meet
applicable local, state, and federal (OSHA) requirements. A personal fall arrest system incorporating a full
body harness must be capable of arresting a user’s fall with a maximum arresting force of 1,800 lbs. (816
kg), and limit the free fall distance to 6 ft. (1.8 m) or less. The deceleration distance must be 42 in. (107

cm) or less.

3.0 INSTALLATION AND USE

WARNING: Do not alter or intentionally misuse this equipment.

Consult with DBI-SALA if using this equipment with components
or subsystems other than those described in this manual. Some
subsystem and component combinations may interfere with the
operation of this equipment.

WARNING: Consult with your doctor if there is any reason to
doubt your fi tness to safely absorb the shock from a fall arrest.
Age and fi tness can seriously affect your ability to withstand falls.
Pregnant women and minors must not use this equipment.

3.1 BEFORE EACH USE of this equipment inspect it
according to section 5.0.

3.2 PLAN your fall arrest system before installing and
using this equipment. Consider all factors affecting
your safety during use. The following list gives some
important points to consider when planning your system:

A. ANCHORAGE BEAM: Select a rigid anchorage beam that is capable

of supporting the loads specified in section 2.4. Joints between
beam sections must be flush to allow the trolley to pass over
smoothly. The beam must have end stops at each end to prevent
the trolley from rolling off the beam. The end stops must be sized
and positioned to safely stop the trolley. The trolley should not
catch or hang-up on the end stop; the trolley must be able to freely
return in the opposite direction after contacting the end stop. See
Figure 5.

Figure 5 - End Stops

Figure 6 - Fall Clearance

B. FALL CLEARANCE: See Figure 6. There must be sufficient

clearance in your fall path to prevent striking an object or lower
level in the event of a fall. The amount of clearance required is
dependent on the application. See personal fall arrest system
manufacturer’s instructions for information on calculating fall
clearance.

C. SWING FALLS: See Figure 7. Swing falls occur when the

anchorage point is not directly overhead. The force of striking an
object in a swing fall may cause serious injury or death. Minimize
swing falls by working as directly below the anchorage point as
possible. Do not permit a swing fall if injury could occur. Swing
falls will significantly increase the clearance required when a self
retracting lifeline or other variable length connecting subsystem
is used. If a swing fall situation exists in your application contact
DBI-SALA before proceeding.

D. SHARP EDGES: Avoid working where parts of the system will be in

contact with, or abrade against, unprotected sharp edges.

E. AFTER A FALL: Any equipment which has been subjected to

the forces of arresting a fall or exhibits damage consistent with
the effect of fall arrest forces as described in section 5, must be
removed from service immediately and destroyed by the user, the
rescuer, or an authorized person.

F. RESCUE: When using this equipment, the employer must

have a rescue plan and the means at hand to implement it and
communicate that plan to users, authorized persons, and rescuers.
