Cleaning, Maintenance and Storage

3.2

Installation Instructions

Refer to the corresponding illustrations on page 30.
(1) Locate a structural steel beam flange with a width of 3" - 10" (76 mm - 254 mm) and thickness of
1/4" - 7/8" (6 mm - 22 mm) capable of withstanding a 5,000 lbf static load in the absence of certifica-
tion or 3,600 lbf static load where certification exists. For multiple personal fall arrest systems, this
static load must be multiplied by the number of trolleys on the beam.
(2) Loosen the threaded secondary safety locks on each toggle plate, then push up on the toggle plate to
allow the adjustable rollers to slide along the notched cross bar.
(3) Keeping the unit perpendicular to the beam, fit the rollers over the edges of the beam flange.
(4) Slide the adjustable rollers so that both sets of rollers are fully resting on the beam flange. The flanges
of the rollers should ride along the outside of the beam, not on it.
(5) Release the toggle plate and pull back on the adjustable rollers to ensure the ratchet teeth are fully
seated in the nearest ratchet notches.
(6) Tug, rock, and twist the anchorage connector in all directions to ensure that it cannot come off of the
flange.
(7) Screw tight the secondary safety locking screws on the bottom of the toggle plate to insure the rollers
cannot move off the edge of the flange.
(8) The rollers must ride on a clear clean surface. Remove any dirt and grit if necessary.
(9) Ensure that the Beam Trolley cannot slide off the end of the beam it is attached to. Weld or bolt in stop-
pers if necessary.
* Always re-adjust according to steps 1-9 above when moving to a new or different beam size.
4 Cleaning, Maintenance and Storage
Cleaning periodically will prolong the life and proper functioning of the product. The frequency of cleaning
should be determined by inspection and by severity of the environment. Clean with compressed air and/or
a stiff brush using plain water or a mild soap and water solution. Do not use any corrosive chemicals that
could damage the product. Wipe all surfaces with a clean dry cloth and hang to dry, or use compressed air.
When not in use, store anchorage connectors in a cool, dry, clean environment, out of direct sunlight and
free of corrosive or other degrading elements.

Inspection

US
5.1

Inspection Frequency

The Beam Trolley must be inspected by the user before each use. Additionally, it must be inspected by a
competent person other than the user at intervals of no more than six months. The competent person
inspection is referred to as Formal Inspection. See sections 5.2 and 5.3 for inspection procedures and
section 5.5 for inspection locations.
If the Beam Trolley has been subjected to fall arrest or impact forces, it must be immediately
removed from service and marked as "UNUSABLE" and returned to MSA, or a person authorized in
writing by MSA, for inspection and repair.
5.2

Procedure for Inspection before each Use

Perform the following steps in sequence. If in doubt about any inspection point, consult MSA or a competent
person authorized to perform Formal Inspection as described in section 5.3.
