| UNPACKING
INFORMATION |
|
|
 |
|
After
removing the trolley from the shipping carton,
carefully inspect the external condition of the cords, control
box, gear reducer and motor for damage that may have
occurred during shipment and handling. Check to make sure
all parts (trolley side frame assembly with control box,
trolley side frame with gear reducer and motor, hook plate,
suspension bolts, spacer washer, spacer tubes, lockwashers
and nuts) are furnished. Also, before attempting to install
the
trolley, make sure that the power supply indicated on the
nameplate is the same as the power supply on which the unit
is to operate. If there is damage, refer to packing slip
envelope for claim procedure. |
|
|
|
|
|
|
|
|
|
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 (3.2 to 4.8 mm) greater than
the beam flange width for straight runway beams, and
3/16 to 1/4 inch (4.8 to 6.3 mm) greater than the beam
flange width if runway system includes sharp curves.
The use of other than our supplied washers may result in
trackwheel to beam flange variations and thus Table 2
will not apply. |
|
|
|
|
| INSTALLATION |
|
|
|
|
|
The
hoist, trolley and hook suspension for suspending the
hoist from the trolley may be packed separately. If
necessary, assemble the hook suspension to the hoist
according to the instruction furnished with the suspension
and/or the instruction in the manual furnished with the hoist. |
|
|
|
|
|
| The
Railstar Motor Driven Trolley is designed for operation at ambient
temperatures of 0° to 100°F (-17 to 38°C). |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
 |
|
|
Now
install the trolley on the beam by sliding one side frame out
far enough to allow 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
to compress the lockwashers. Suspend the hoist from the trolley
hook plate so that the hoist power and control cords are son
the control box side of the trolley. Verify distance between
trackwheel flanges (dimension "X") as noted above. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| The
stops must be positioned so as to not exert impact force on
the hoist frame or trolley wheels. They must contact the ends
of the trolley side frames. |
|
|
|
|
|
|
|
|
|
|
| TROLLEY
TO BEAM |
|
|
|
|
|
| It
is recommended that the trolley be mounted on the beam prior
to suspending the hoist from the trolley. Before attempting
to mount the trolley on the beam, measure the actual width of
the beam flange on which the trolley is to operate. Using this
measurement determine the arrangement of the spacer washers
using Figure 1 and Table 2. Chart A of Table 2 shows the washer
arrangement for the 1/8-2 ton (250-2000 kg.) trolley, while
Chart B provides data for the 3 ton (3000 kg.) trolley. Loosely
assemble the side frames, hook plate, spacer washers, spacer
tubes, lockwashers and nuts on the suspension bolts as shown
in Figure 1. |

Electrical
Connections |
|
|
|
The
trolley electrical connections must be completed as
shown in Figure 2 (see below). The hoist and trolley must
be supplied with adequate electrical power in order to
operate properly. For proper operation, the voltage,
(measured at the trolley terminal board with the hoist
operating in the up direction with full load) must be
as indicated in the table below. |

Signs
of inadequate electrical power (Low Voltage) are: |
|
|
•
Noisy hoist or trolley operations due to brake and/or
contactor chattering.
• Dimming of lights or slowing of motors connected
to the same circuit.
• Heating of the hoist and/or trolley motors and other
internal components as well as heating of
the wires
and connectors in the circuit feeding the
unit.
• Failure of the hoist to lift the load due to motor stalling.
• Blowing of fuses or tripping of circuit breakers. |
|
|
|
|
|
|
|
|
 |
|
To
avoid these low voltage problems, the trolley must
be connected to an electrical power supply system that
complies with the National Electrical Code and
applicable local codes. This system must also be rated
for a minimum of 20 amps and it must have #14 AWG
or larger wiring, a disconnecting means, overcurrent
protection (slow blow fuses or inverse-time type
circuit breakers) and provisions for grounding. |

If
grounding is to be through the metal to metal contact between
trackwheels and the operating flange of the beam, make sure
that: |
|
|
|
|
1.
No paint or other insulating material is applied to the
operating flange of the beam.
2. No paint or other insulating material is applied to the
trackwheel treads. |
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
Remember,
operation with low voltage can void our
repair/replacement policy. When in doubt about any
of the electrical requirements, consult a qualified
electrician. Always disconnect the power from the
power supply system and lockout/tagout
disconnecting means before servicing the trolley or
hoist. |

Low
voltage can also be caused by using an undersize extension
cord to supply power to the trolley. The following chart should
be used to determine the size wires in the extension cord in
order
to minimize the voltage drop between the power source and the
trolley control box. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The
following wiring diagrams show connections to be
made within trolley control box. For special units, see
wiring diagram supplied with unit. Note: Trolley power
cord must be replaced (if necessary), hoist power cord
must be connected to the trolley power circuit, hoist
control cord must be connected to the trolley and wired to
the trolley control cord and the control cord must be
shortened (if necessary) before the system supplying
power to the trolley is energized. |
|
In
addition, as shipped from the manufacurer, the three
phase trolleys are connected to operate on 380-415 Volts,
3 Phase, 50 Hertz or 440-480 Volts, 3 Phase, 60 Hertz.
These units can be converted to operate on 220 Volts, 3
Phase, 50 Hertz or 230 Volts, 3 Phase, 60 Hertz. To do
this, reconnect the motor leads to the motor cord and
move lead #10 at the transformer terminal board to the
"220" position as shown on the wiring diagram supplied
with the trolley or wiring diagram 03702. Be sure to re-
mark, using tape or some other suitable material, the
trolley identification plate to indicate that the unit is
suitable for operation on 220-3-50 or 230-3-60. |
|
|
|
|
|
|
|
|
| CONTROL
STATION |
|
|
|
The
standard trolleys are supplied with a four button
control station. The hoist control buttons are the single
speed type that can be used to control a single speed hoist
that is equipped with a reversing contactor. The trolley
control buttons are also the single speed type. |
|
|
|
|
|
|
|
|
|
To
shorten the cord, measure the distance the control station is
to be raised. Remove the cover from the control station and
disconnect the wires from the various terminals. Using wire
cutters, cut the external wire rope strain relief just above
the fitting used to form the loop. Measuring from the end of
the longest wire, cutoff the cord the distance the station is
to be raised. Using the cut-off piece of cord as an example,
remove the outer jacket and prepare the individual wires of
the shortened cord accordingly. |
|
|
|
|
|
|
|
|
Unless
ordered special, the control station is suspended
from the trolley control box by a cord that is
approximately 16'-3" (4.95 M) long. If this is too long
for
your application, the cord should be shortened so that the
control station is approximately four feet above the
operating floor. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Slide
the prepared cord through the grommet on top of the
control station. Clamp the cord to the top of the control
station and, using the wiring diagram supplied with the
trolley, connect the wires to the various terminals. Now,
remove the insulation from the wire rope stain relief. Slide
the clamp sleeve (from the wiring kit) up on the wire rope
and feed the rope around the pin at the top of the station.
Feed the end of the wire rope through the other side of the
clamp sleeve. Pull on the end of the wire rope until it
supports the control station. Slide the clamp sleeve down
to form a tight loop and then squeeze the clamp sleeve
using a vise or very large pliers to secure the loop.
Reattach the cover to the control station. |

| TROLLEY
POWER CORD |
The
short power cord furnished is for use with a collector and bus
system. It should be discarded if a cable is to supply
power to the trolley. Connect the "new" power cord
to the terminal board as shown in Figure 3. The box connector
must be made tight on the cable, and if necessary, a separate
strain relief should be provided to prevent any stress on
the wires of the power cord. |
 |
|
|
FIGURE

|
|
|
|
| HOIST
CONTROL CORD |
Energize
the power supply system. Depress the trolley
control button. If the movement of the trolley does not
agree
with the direction arrows on the control station, de-energize
the power supply system. Remove trolley control
box cover and interchange the red and black wires as
shown in Figure 5.
|
|
The
hoist control cord must be shortened and run into the
trolley control box so that the hoist can be controlled from
the four button control station suspended from the trolley.
To do this, form a loop in the hoist control cord as shown
in figure 2. Allowing 5 to 6 inches (127.0 to 152.4 mm)
for making connections inside the control box, cut-off the
hoist control cord. The hoist control station and excess
cord can be discarded. Strip 5" to 6" (127.0 to 152.4
mm)
of the outer jacket from the cord to expose the individual
wires. Run the cord through the box connector and firmly
tighten the outer nut of the connector to secure the cord.
Strip .3" (9.5 mm) of insulation from the individual wires.
*Connect the brown, yellow and blue wires to the terminal board
as shown in Figure 4. Loosen one of the screws used
to attach the terminal board or transformer to the control
box. Firmly crimp a spade type terminal (from the wiring
kit) to the end of the green wire and slide the terminal
under the head of the screw. Firmly tighten screw to
insure proper ground. |
|
|
|
|
|
|
Now,
depress the "up" button. If the hoist hook lowers,
de-energize the power supply system and interchange the red
and black wires of the hoist power cord at the terminal
board as shown in Figure 5. |

THREE-PHASE
UNITS |
|
|
|
A
three phase motor can rotate in either direction
depending on its connection to the power supply.
Therefore, the direction of trolley and hook travel
relative to the selected indicated direction must be
checked before the trolley is put into service. If the hoist
power cord is not properly connected to the terminal
board inside the trolley control box, serious damage
could result and the hoist limit switches are ineffective.
The trolley should be checked first and then the hoist. |
