* Minimum Beam
Radius ft.(M) 4’-0”(1.22) 5’-6”(1.68)
*Dimension applies to minimum S-beam and will vary with larger S-
beams
Before installing geared or motor driven trolleys on the
beam, lubricate the trackwheel gears and pinion with
Texaco Novatex #2 or equivalent heavy cup grease.
On open end beams, remove rail stops, lift hoist/trolley into
position and slide the hoist/trolley assembly onto beam
flange. Reinstall the rail stops.
On closed end beams, loosen the suspension bolt nuts on
one side of trolley and slide one side frame out far enough
to clear the beam flange. Lift hoist/trolley assembly up so
that trackwheels are riding on beam flange. Draw side
frames together by tightening the suspension bolt nuts
snugly.

Be sure to install cotter pins through slotted nuts and hole
in suspension bolts and spread legs of cotter pins to
secure.
On geared trolleys, the bottom of the hand chain loop is
normally located two feet (0.6M) above the floor. If it is
desired to change this, find the unwelded link and open it
by spreading with a chisel or twist one end with a wrench
while holding the other end in a vise or another wrench.
Remove an even number of links ( 2,4,6, etc.) as neces-
sary to shorten the chain or add an even number of links to
lengthen the chain (when lengthing the chain, another open
link will be required and this can be made from a welded
link by cutting through weld with a hacksaw). Make certain
that the chain is not twisted–then re-install and close open
links.
NOTE: AFTER THE UNIT IS CONNECTED TO THE
POWER SUPPLY SYSTEM (SEE BELOW), SUSPEND A
CAPACITY LOAD FROM THE HOIST AND OPERATE
THE TROLLEY OVER THE ENTIRE LENGTH OF THE
RUNWAY OR MONORAIL SYSTEM TO BE SURE THAT
THE ADJUSTMENTS AND OPERATION IS SATISFACTO-
RY. ON SYSTEMS WITH CURVES, THE EDGES OF THE
RAIL AT THE CURVED SECTIONS SHOULD BE KEPT
LIGHTLY LUBRICATED WITH GREASE.
INSTALLING TROLLEY
SUSPENDED HOIST ON BEAM
Stops must be positioned to contact the trolley side frames
and not exert impact force on the hoist.
Trolleys are mounted on the hoist prior to shipment and
side frames are positioned for the nominal beam flange
specified on the order. However, due to variations in beam
flange widths, actual beam flange width should be mea-
sured to determine the exact distribution of the spacer
washers. Refer to Table 2.
On all trolleys, the distance between trackwheel flanges
(dimension “x”) should be 1/8 to 3/16 inch (3.17 to 4.77
mm) greater than the flange width for straight runways,
and 3/16 to 1/4 inch (4.77 to 6.35 mm) greater than the
flange width if the runway includes sharp curves. If dimen-
sion “x” is not as specified, rearrange the spacer washers.
Make sure the number of spacer washers at “B” and “C”
are the same or differ by one spacer washer maximum.
WARNING
Operating the trolley on a beam that has no rail stops
may allow the trolley to fall off the end of the beam.
TO AVOID INJURY:
Install rail stops at each end of the beam on which the
trolley is to operate.
WARNING
If CM’s washer spacing recommendations are not fol-
lowed, trolley may fall from beam.
TO AVOID INJURY:
Measure the actual beam flange on which the trolley is to
operate and use Table 2 to determine the arrangement of
the spacer washers for that flange width.
NOTE: USE OF OTHER THAN CM SUPPLIED SPACER
WASHERS MAY CAUSE IMPROPER TRACKWHEEL
SPACING AND THUS TABLE 2 WILL NOT APPLY.
