Table 3. Series 635 Low Headroom Trolley Side Frame Spacing
Note: Due to the variations in beam flange widths,
it is suggested that the beam flange width be mea-
sured to determine the exact distribution of spacer
washers. The distance between trackwheel flanges
(dimension “X”) should be 1/8 to 3/16 inch (3.18 to
4.77 mm) greater than the beam flange width for
straight runway beams, and 3/16 to 1/4 inch (4.77 to
6.35 mm) greater than the beam flange width if run-
way system includes sharp curves. Also, the use of
other than CM supplied washers may result in track-
wheel to beam flange variations and thus Table 3
will not apply.
On the 1/8 to 2-ton (125 to 2000 kg) trolleys, assemble the
suspension lug on hoist to the trolley on beam as shown in
Figure 10. The lug is inserted in the trolley load bracket and
retained by the vertical load bar pin. A socket head cap
screw and lockwasher are used to keep the in in place.
For the 3-ton (3000 kg) trolley, a shackle and pin assembly
consisting of a pin retained in a central position by retainers
is packed loose with the suspension. Insert this assembly
into the opening in the top of the load bracket with the legs of
the shackle down. Position the shackle pin in the groove pro-
vided for the same in the load bracket making sure it is cen-
tered between the suspension bolts.
Now install the trolley on the beam by sliding one side frame
out far enough to allow all the trackwheels to clear the beam
flange. Lift the trolley up so that the trackwheels are riding on
the beam, draw the side frames together and tighten the nuts
snugly. Insert the cotter pins through the slotted nuts and
holes in the supension bolts and spread the legs of the cotter
pins to secure.

WARNING
If CM’s washer spacing recommendations are not followed,
trolley may fall from beam.
TO AVOID INJURY:
Measure the actual beam flange on which the trolley is to
operate and use Table 3 to determine the arrangement of the
spacer washers for that flange width.
On the 3 ton (3000 kg) trolley (refer to Figure 11), drive one
retaining pin into the hole on one end of the lug pin. Raise
the hoist into position so that the lug is between the legs of
the shackle. Align the holes in the shackle and lug. Insert
the lug pin in the aligned holes and secure the lug pin by
driving the remaining retaining pin into the hole in the lug
pin. Make certain that the shackle pin is properly seating in
the load bracket by manipluating the hoist and checking for
freedom of movement (swinging) in both planes and all four
directions.
Note that the shackle pin should be retained and centered
in the shackle by the retainers.
