INSTALLATION (CONTINUED)
Note: Due to the variations in beam flange widths, it is
suggested that the beam flange width be measured 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 runway system
includes sharp curves. Also, the use of other than CM supplied
washers may result in trackwheel 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 provided for the
same in the load bracket making sure it is centered 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 suspension bolts and
spread the legs of the cotter pins to secure.
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 manipulating the hoist and checking
for freedom of movement (swinging) in both planes and all four
directions.
NOTE: The shackle pin should be retained and centered in the
shackle by the retainers.

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
satisfactory. On systems with curves, the edges of the rail at the
curved sections should be kept lightly lubricates with grease.
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.
POWER SUPPLY AND ELECTRICAL
CONNECTIONS
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 (.75 kW) 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). Furthermore, the suspension system on
which the hoist is mounted must also be permanently grounded.
Before connecting the hoist to the power supply, check that the
power to be used agrees with that shown on the hoist identification
plate. In addition, for a three phase, dual voltage unit, check the
voltage shown on the tag attached to the power cord.
