6.0 Unpacking
Open shipping container and check for shipping
damage. Report any damage immediately to
your distributor and shipping agent. Do not
discard any ship ping material unt il the Trolley is
assembled and running properly.
Compare the contents of your container with t he
following parts list to make sure all parts are
intact. Missing part s, if any, should be reported
to your distributor. Read the instruction m anual
thoroughly for assembly, maintenance and
safety instructions.
6.1 Contents of Shipping Container
1 Electric Trolley
1 Cord holder with cable tie
12 Phillips Pan Head Sc re ws, M5x 12
12 Lock Washers, 5mm
1 Owner's Manual
1 Warranty Card
7.0 Installation & Assembly
Figure 2
6. Re-install th e p late ( C) and two h ex n uts ( B),
and tighten the hex nuts.
7. Reinstall the adjusting screw and hex nuts
(A) and adjust to the proper width.
8. Double-check the wheel clearance on the
beam, and make further adjustments if
necessary.
The ET-C Series trolley is designed to run on
standard “I” beams, wide-f langed “H” beams, or
curved track with a minim um r adius shown in the
chart on page 5.
7.1 Mount Trolley to Beam
The trolley is heavy; use an
assistant or a lifting device to help st abiliz e it
while you assemble it to the beam.
1. Loosen the hex nuts (A, Figure 2) on the
adjusting screw, and remove the adjusting
screw.
2. Remove the two hex nuts (B, Figure 2) with
the plate (C, Figure 2).
3. Slide out the suspension shaft with the
spacers (D, Figure 2).
4. Assemble the trolley to the beam. The trolley
must be installed on a be a m with a minimum
clearance (wheels to flange) of 1/16” to a
maximum of 1/8” on eac h side of the beam
(see Figure 1, page 5). Position the side
plates (E, Figure 2) to achieve this
measurement on your beam.
7.2 Power and Pendant Cords
NOTE: A pendant c ord is not supplied with the
trolley, and must be purc hased s epar ate l y. If you
need to change th e voltage requirem ents on the
trolley, it is more convenient to do that before
installing a pendant cord. See “Voltage
Conversion” on page 9.
1. Thread the cord holder (Figure 3) into the
hole on the motor side plate and tighten th e
jam nut and lock washer. The ring on the
cord holder should be positioned vertically.
5. Re-install the suspensio n shaft, while using
the spacers (D) to achieve the required
width. Spacers must be moved in sets of
two, placing equal number s on both sides of
the hoist hanger to m aintai n the c en terl ine of
the trolley. Place any extra spacers on the
outside of the shaft, as shown in Figure 2.
Figure 3

2. Insert the male plug of the pend ant cord into
the socket on the trolley. See Figure 4.
Secure the connection by tightening the
cover nut with your fingers.
3. Attach the pendant cord t o the cord holder.
The cord must be sec ur ed t o th e c ord holder
in a way that relieves strain on the
connections. One method of doing this is to
form a loop in the pendant cord and place
the cable tie as shown in Figure 5. Do not
tighten the cable tie yet.
4. Create sufficient slack in the pendant cord
where it passes under the I- beam (Figur e 6)
so that the cord will not rub against the
beam.
5. Tighten the cable tie to secure the pendant
cord to the cord holder.
7.3 Mounting Your Hoist
This trolley has been des igned to work with the
JET C-Series Hoist. The y can be connected so
that one pendant cord and power cord will
operate both trolley and hoist. Make sure the
hoist has been set to the same voltage
specifications as the trolley.
Make connections fr om the trolley to your hoist
as follows:
1. Hang the hoist on the trolley hanger, using
hook or lug mount. (See page 8 for
instructions on installing the optional lug
mount.) The hoist should be positioned so
that the electrical so cket on the trolle y is on
the same side as the sockets on the hoist,
as shown in Figure 6.
Figure 4
Figure 5
2. Remove the power cord and pendant cord
from the hoist.
3. Connect the two 4P and 7P plugs of the
trolley cords into their appropriate sockets
on the hoist.
Figure 6
7
7.4 Installing Lug Mount Accessory
1. Assemble the side plates, hoist ha nger and
lug mounting shaft, as shown in Figure 7.
2. Install the hinge plates, lock washers and
hex cap screw to secure the assembly.
3. On the electric hoist, remove the two
screws, hook pin plate, hook pin, etc.
(Figure 8)
4. Remove the top hook assembly from the
hoist, and replace it with the lug mount
accessory as shown in Figure 9. Re-install
the hook pins, hook pin plates, screws and
washers. Firmly tighten the screws.
8.0 Electrical Instructions
Electrical connections must
be made by a qualified electrician in
compliance with all relevant codes. This
machine must be properly grounded to help
prevent electrical shock and possible fatal
injury.
8.1 Grounding
In the event of a malfunction or breakdown,
grounding provides a path of least res istance f or
electric current to reduce the risk of electric
shock.
This machine’s power cord must be fitted with
an appropriate UL/CS A listed plug, or it can be
“hard-wired” directly to a control panel. If hardwired, make sure a disconnect is available for
the operator.
Figure 7
Figure 8
If a plug is installed, it m ust have an equipm entgrounding conductor and a grounding prong.
The plug must be plugged into a m atching outle t
that is properly installed and grounded in
accordance with all local codes and ord inances.
Do not modify the plug.
Improper connection of the equipmentgrounding conductor can result in a risk of
electric shock. The conductor with insulation
having an outer surface that is green with or
without yellow stripes is the equipmentgrounding connector. If repair or replacement of
the electric cord or plug is necessary, do not
connect the equipment-gr ounding c onductor to a
live terminal.
Figure 9
8
Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to
whether the tool is properly grounded.
Repair or replace damaged or worn cord
immediately.
8.2 Voltage Conversion
The single phase models (ET-1C) are
designed for 115 volt or 23 0 volt oper atio n. T hey
are pre-wired for 230 volt. The three phase models (ET-3C) are designed for 230 volt or
460 volt operation. They are pre-wired for 460V.
To switch voltage :
1. Disconnect trolley from power supply, and
disconnect the pendant cord from the trolley.
2. Remove the two screws and lock washers
on the underside of the housing (s ee Figure
10) and slide the protect ive band out of the
way. Remove the housing.
3. Carefully pull the plug out of the current
socket and insert it into the new sock et (see
Figure 10). Make sur e the notch on the plug
fully engages the socket.
4. Re-install the housing, re-position the
protective band, and insert the screws and
lock washers. Tighten the screws securely.
Test the motion of the hoist also:
2. With no load o n the load h ook, pr ess the U P
button very briefly and observe ho ist action.
The hook should m ove upward. (Two speed
models have a two-position UP button.
Press the button onl y part wa y to operate l ift
motor at slow speed, press fully to operate
at high speed.)
3. If no motion occurs when the UP button is
pressed and the hoist is connected to a
three phase power supply, the po wer supply
wires are incorrectly positioned.
4. Switch any two of the three suppl y wires at
the power source. Do not attempt to rewire
the hoist/trolley circuit or pendant
controls for this problem. Use the same
safety precautions when reversing two of the
supply wires as was used when the wires
were originally connected.
5. Re-connect power and test hoist and trolley
movement again without load. Run hoist to
the complete lifting height to ensure limit
switches are operating properly.
Refer to your hoist manual for more detailed
instructions on operation and testing of the hoist.
8.4 Extension Cords
If an extension cord is nece ssar y, make s ure the
cord rating is suitable f or the am perage lis ted on
the trolley’s motor plate. An undersize cord will
cause a drop in line voltag e resulting in loss of
power and overheating.
Figure 10
8.3 Inspecting Trolley Motion
1. Before closing the circuit break er and tes t ing
the trolley, check that wiring has been
complete. If the trolley cannot be observed
when the circuit breaker is closed, s tation a n
observer within sight of the trolley to report
any movement when powe r is applied to the
trolley. Be prepared to disconnect power if
trolley motor starts when the power is
applied. The trolle y must remain motionless
when power is applied. F ind and cor rect a ny
problems before continuing.
The chart in Figure 11 shows the correct size
cord to use based on cord length and motor
plate amp rating. If in doubt, use the next
heavier gauge. T he smaller the gauge number,
the heavier the cord.
