between the trolley trackwheel flanges and the beam
flange width should be measured to determine the exact
distribution of the spacer washers. The number of spacer
washers between side frames and load bracket should
be the same or differ only by one spacer to keep the hoist
hook centered under the beam.
Figure 7. Series 635 Low Headroom Trolley
Note: Due to the variations in beam flange
widths, it is suggested that the beam flange
width be measured to determine the exact distri-
bution of spacer washers. The distance between
trackwheel flanges (dimension “X”) should be
1/8 to 3/16 inch greater than the beam flange
width for straight runway beams, and 3/16 to 1/4
inch 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
trackwheel to beam flange variations and thus
Table 2 will not apply.
3. Install the trolley on beam by sliding one side of frame out
far enough to allow the trackwheels to clear the beam
flange.
4. Draw the side frames together and assemble cotter pins.
5. With the trolley mounted on the beam, attach the hoist by
inserting the suspension lug into the trolley load bracket
and inserting the suspension pin through the load bracket
and suspension lug as shown in Figure 8. Secure the pin
using the socket head cap screw and lockwasher.
6. Thread the socket head cap screw and lockwasher into
load bracket and tighten securely.
7. Now, refer to “Power Supply and Electrical Connections”
on this page and complete the hoist installation procedure.
8. Then with a capacity load on hoist, operate trolley over
the entire length of runway or monorail system to be sure
that the adjustment and operation is satisfactory. On sys-
tems with curves, keep the rail edges at the curved sec-
tions lightly greased.

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 2 to determine the arrangement of the
spacer washers for that flange width.
Figure 8. Attaching Hoist to Trolley
Series 635 Motor Driven Trolley
To attach the hoist to the trolley, a lug suspension (Figure 3)
is required. The trolley and lug suspension are packed sepa-
rately, and the hook suspension that is packed with the hoist
may be discarded. To install the lug suspension, follow the
instructions for attaching the suspension on page 4. The
Motor Driven Trolley must be assembled and wired to the
hoist by the user per the manual packed with the trolley.
Chain Container
For installation instruction, refer to instruction sheet packed
with the chain container.
POWER SUPPLY AND ELECTRICAL
CONNECTIONS
All Hoists
The hoist should be connected to a branch circuit which
complies with the requirements of the National Electrical
Code and applicable local codes.
It is recommended, especially for a single phase hoist with a
one horsepower motor, that a line of adequate capacity be
run directly from the power supply to the hoist to prevent
having problems with low voltage and circuit overloads.
For grounding of the hoist, the power cord includes a
grounding conductor (green wire). On a standard single
phase unit this cord is equipped with a three-prong plug. Be
sure that the receptacle opening which receives the longest
prong is properly grounded. Furthermore, the suspension
system on which the hoist is mounted should also be perma-
nently grounded.
Before connecting the hoist to the power supply, check that
the power to be used agrees with that shown on the hoist
identification label. In addition, for a three phase, dual volt-
age unit, check the voltage shown on the tag attached to
power cord.

WARNING
An excessively worn beam flange may fail and allow the trolley
to fall from the beam.
TO AVOID INJURY:
Periodically inspect the beam flange for wear. Replace beam if
flange is worn.
