VARIABLE SPEED ELECTRIC CHAIN HOIST WITH
OPTION
SERIES 635 MOTOR DRIVEN TROLLEY
The motor driven trolleys (see Figure 4) are self-contained and
supplied complete with independent controls and wiring, including a
four-directional control station. A rigid lug suspension is required to
suspend the hoist from the Motor Driven Trolley. The hoist and trolley
are joined electrically by connecting the hoist control and power
cords (supplied) into the hoist or trolley. The trolley is adjustable for
operation on a range of American Standard “S” beams. It will also
operate on flat flanged beams.
CM UNIVERSAL (UT) TROLLEY
The CM Universal Trolley (UT) is designed to fit virtually all Columbus
McKinnon powered chain hoists up to 3-tonne capacities. The
rugged UT is available as a convertible plain unit, a geared unit ideal
for precise hoist positioning, and a motorized unit that’s perfect for
applications requiring high-cycling and long-distance hoist travel.

enables quick and easy programming,
maintenance, monitoring, and troubleshooting of the Lodestar – all
from a tablet or smartphone. And, it works wirelessly, so you don’t
need to attach a programming cable to access information.
INSTALLATION
UNPACKING INFORMATION
When received, the hoist should be carefully inspected for damage
that may have occurred during shipment or handling. Check the
hoist frame for dents or cracks, the external cords for damaged or
cut insulation, the control station for cut or damaged enclosure, and
inspect the load chain for nicks and gouges. If shipping damage has
occurred, refer to the packing list envelope on the carton for claim
procedure.
Before installing the hoist, make sure that the power supply to which
it will be connected is the same as that shown on the nameplate
located on the side of the hoist.
NOTE: See Electrical Installation instructions.
INSTALLING THE SUSPENSION
A. Single-Reeved Units:
Remove the hook suspension and (2) suspension screws from the
packaging. Place the suspension assembly into the recess on top of
the hoist so that the adapter body follows the contour of the hoist.
Insert the suspension screws through the holes in the adapter and
hand-thread these into the self-locking nuts enclosed in the hoist.
Securely tighten the screws to the recommended seating torque (see
Table 13) using a 12-point socket: 3/8” for Models A, AA, B, C & F
and 1/2 for models J & L.
Use of impact tools (electric or pneumatic) may cause premature
failure of attaching hardware.
B. Double-Reeved Units:
Remove the hook suspension, (2) suspension screws, (1) dead end
pin, (1) washer, and (1) cotter pin from the packaging. Note that the
suspension includes a dead end bolt and block for supporting the
dead end of the load chain as shown in Figure 7.
Place the suspension assembly into the recess on top of the hoist.
The dead end block should project through the bottom of the hoist
with the pin hole and slot aligned to the underside of the hoist as
shown in Figure 8. If these are not aligned as shown, lift the head of
the bolt from the hex recess in the adapter, turn the bolt and block
assembly, and reseat the bolt head to obtain the proper alignment.
Do not change the position of the dead end block on the bolt to
attain this alignment.
Check the position of the pin hole in the dead end block to make
sure it has not been disturbed from its factory setting. The distance
from the top of the pin hole to the bottom of the hoist should not
exceed 1/4” (6.35 mm) for Models E & H and 7/16” (11.11 mm) for
Model R. If the distance is not correct, adjust the position of the
dead end block to obtain the proper distance.
Insert the suspension screws through the holes in the adapter and
hand-thread these into the self-locking nuts enclosed in the hoist
frame. Securely tighten the screws to the recommended seating
torque (see Table 13) using a 12-point socket: 3/8” for Models E & H
and 1/2” for Model R.
Figure 7. Double-Reeved Suspension Assembly
C. Triple-Reeved Units:
These hoists have a sheave hanger which is loosely connected to
the top of the frame by a thin metal plate for shipping purposes.
To attach the suspension, support the sheave hanger from the
underside of the hoist and remove the nut and seat from the sheave
stud. Remove and discard the shipping plate and retain the sheave
stud nut and seat since they will be reused later.
Remove the suspension assembly from the carton and the two
suspension screws. Place the suspension assembly over the sheave
stud and into the recess on top of the hoist. Insert the suspension
screws through the holes in the suspension adapter and hand-thread
these into the self-locking nut enclosed in the hoist. Securely tighten
the screws to the recommended seating torque (see Table 13) using
a 12-point, 1/2” socket.
After the suspension assembly is installed, secure the sheave stud
to the suspension adapter using the round slotted nut and seat that
were formerly used to attach the shipping plate to top of the hoist
frame. Place the seat over the stud with the flat side down and then
rotate the seat so that there is clearance between the seat and the
suspension lug or hook. Assemble the nut to the stud and turn the
nut by hand until the nut seats in the seat and the sheave hanger
is snug in the frame. Then back off the nut until the hole in the stud
is in line with one of the slots in the nut. Using a hammer, drive the
retaining pin (packed with the suspension assembly) into the hole
in the sheave stud until the end of the pin is flush with the edge of
the nut.
Using other than CM-supplied high-strength suspension screws to
attach the suspension adapter to the hoist may cause the screws
to break and allow the hoist and load to fall.
