Contents of the Shipping Containe r

1 Electric Trolley
1 Cord holder with c able tie
12 Phillips Pan Head Screws, M5x12
12 Lock Washers, 5mm
1 Owner's Manual
1 Warranty Card

Installation and Assembly

The ET-C Series trolley is designed to run on
standard “I” beam s, wide-fl anged “H” beams, or
curved track with a minimum radius shown in the
chart on page 5.

Figure 2

6. Re-install the plate (C) and two hex nut s (B),
and tighten the hex nut s.

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.

Power and Pendant Cords

Mount Trolley to Beam

The trolley is heavy; use an

assistant o r a l ifting device to help stabilize 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, Fi gure 2) with
the plate (C, Figure 2) .

3. Slide out the suspension shaft with the
spacers (D, Figure 2) .

4. Assem ble the trolley to the beam. The trolley
must be installed on a beam with a mi nim um
clearance (wheels to flange) of 1/16” to a
maximum of 1/ 8” on each side of the beam
(see Figure 1, page 5). Position the side
plates (E, Figure 2) to achieve this
measurement on your beam .

5. Re-i nstall the suspen sion shaf t, while using
the spacers (D) to achieve the required
width. Spacers must be moved in sets of
two, placing equal num ber s on both si des of
the hoist hanger to maintain the centerline of
the trolley. Place any extra spacers on the
outside of the shaft , as shown in Fi gur e 2.

NOTE: A pendant c ord is not supplied wit h the
trolley, and must be pur c hased sep ar ately. If you
need to change the v oltage requir ements 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 plat e and tighten the
jam nut and lock washer. The ring on the
cord holder should be posi t ioned vertically.

Figure 3

6

2. Insert the mal e plug of the pendant cord i nt o
the socket on the trolley. See Figure 4.
Secure the connection by tightening the
cover nut with your fi nger s.

3. Att ach the pendant cord to the cord holder.
The cord m ust be secured to the cord holder
in a way that relieves strain on the
connections. O ne method of doi ng 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 passe s under t he I-be am (Figur e 6)
so that the cord will not rub against the
beam.

5. Ti ghten the cable tie to secure the pendant
cord to the cord holder.

Mounting Your Hoist

This troll ey has been designed to work with the
JET C-Seri es Hoist. They can be con nected 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 connecti ons from the t rolley 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 el ectrical socket on t he trolley i s 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

Installing Lug Mount Accessory

1. A ssemble the side pl ates, hoist hanger 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, ho ok pin plates, screws and
washers. Firmly tighten the screws.

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.

Figure 7

Grounding

In the event of a malfunction or breakdown,
grounding prov ides a path of least resistance f or
electric current to reduce the risk of electric
shock.

This machine’s power cord must be fitted with
an appropriate UL/ CSA listed plug, or it can be
“hard-wired” directly to a control panel. If hard­wired, make sure a disconnect is available for
the operator.

If a plug is install ed, it must hav e an equipment­grounding conductor and a grounding prong.
The plug must be pl ugged i nto a matchi ng outl et
that is properly installed and grounded in
accordance wit h all local codes and ordinanc es.
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 equi pment-grounding conductor to a
live terminal.
