1.2 PURPOSE:
The 4810 Lockjaw 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 or
a vertical lifeline, connector to attach the 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.
1.3

appendix C, OSHA1926.502., ANSI Z359.1-2007.
2.0 SYSTEM REQUIREMENTS
2.1 COMPATIBILITY OF COMPONENTS: Reliance equipment is designed for
use with 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 completesystem.
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 Reliance Industries 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. Connectors must be
compatible in size, shape, and strength. Self-locking snap hooks and carabiners
are required by ANSI Z359.12 and OSHA.
2.3
MAKING CONNECTIONS: Only use self-locking and self-closing 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 prior to eachuse.
Reliance connectors (snap hooks and carabiners) are designed to be used only
as specified in each product’s user’s instructions. The following connections must
not be made.
A.
To a D-ring to which another connector is attached.
B.
In a manner that would result in a load onthe gate.
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 eachother.
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.

CAUTION: Large throat snap hooks should not be connected to standard size
D- rings or similar objects which will result in a load on the gate if the hook or
D- ring twists or rotates. Large throat snap hooks are designed for use on fixed
structural elements such as rebar or cross members that are not shaped in a
way that can capture the gate of thehook.
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 thestructure.
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. 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 (2:1), and is
supervised by a qualified 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., and limit the free fall distance to 6 feet or less. The deceleration
distance must be 42 inches or less. Freefall distance cannot exceed
subsystem manufacturer’s requirements, see instructions for moreinformation.
3.0 INSTALLATION AND USE:
WARNING: Do not alter or intentionally misuse this equipment. Consult with
Reliance 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.
3.1
BEFORE EACH USE of this equipment inspect it according to section5.2
3.2
PLANNING YOUR INSTALLATION: You must plan the proper
configuration of your personal fall arrest system before installing and using this
equipment. All equipment must be inspected prior to use. Consider all factors
affecting your safety during use. The following list gives some important points
to consider when planning yoursystem:
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. The trolley must be able
to freely travel the full length of the work operation area without obstructions or
coming in contact with adjacent structures and components. Trolley should be
kept directly overhead at all times and the beam must be level and free from
damage and deformation.

8
B. FALL CLEARANCE: 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 personalfall arrest sys-
tem manufacturer’s instructions for information on calculating fallclearance.
C.
SWING FALLS: 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 Reliance Industries 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 authorizedperson.
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, andrescuers.
3.3 INSTALLATION:
ATTACHING TROLLEY TO BEAM:
Step 1. Measure the beam flange width to determine the distance needed
between the trolley wheels pre-adjustment, and it meets the requirements of
section 1.3.A.
Step 2. Loosen the Threaded T-Handle lock nut and thread to the base of the T-
Handle. Use T-Handle to open the wheels to the beam flange width, or the
maximum trolley adjustment.
Step 3. Slide the trolley wheels on the Threaded T-Handle side onto the near
side flange of the I-Beam. (See Figure 2) Raise the trolley so that the trolley
wheels are in-line with the far side flange of the I-Beam (See Figure 3) and tighten
the Threaded T-Handle until the flanges of the trolley wheels are tight against the
outer edges of the I-Beam flange. (See Figure 4) Loosen the Threaded T-Handle
until there is between 1/16 inch and 1/8 inch of total gap between the flanges of
the trolley wheels and the outer edges of the I-Beam flange. The distance
between the outer edges of the I-Beam flange and the flanges of the trolley
wheel
MUST NOT EXCEED 1/8 INCH TOTAL SPACE!

Step 4. Tighten the Threaded T-Handle lock nut tight against the trolley threaded
boss and torque to 35 ft/lbs.
