I. INTRODUCTION
Fast, safe and economical unloading of covered hopper cars continues to be a problem
at most unloading sites. One of the biggest contributors to this problem is the often
time-consuming and difficult job of opening and closing bottom gates or doors of these
hopper cars. Lading compaction, weather conditions, age, abuse or corrosive or gritty
bulk materials can combine to prevent gate mechanisms from operating smoothly.
Regardless of cause, the costs associated with the problem are significant. Delays in
emptying the cars means slow car turnaround, increased demurrage costs and
interrupted production schedules. And, even more importantly, the chance of worker
injury is high since at many unloading sites clumsy or dangerous makeshift or wrong
tools are used during the "fight" to open a stubborn gate.
WORKMASTER has developed a line of Hopper Car Gate Openers and accessories
which provides a safe, efficient and economical solution to the problem of opening
easy, medium and hard-to-open hopper car gates.
There are pneumatic, electric and manual units available producing 1,000 to
13,000 ft-lbs of torque to eliminate the need for "cheater" bars, sledge hammers, jacks,
and other improper tools sometimes used on this difficult job.
This Operator's Guide details the installation, use, and maintenance of our GO-E2
Electric Hopper Car Gate Opener. Experience has shown that the GO-E2 Opener will
open easy to moderately difficult car gates. However, that same experience
demonstrates that total satisfaction in use depends on attention to detail in installing,
using, and maintaining the Unit.
The operating principle is simple. The GO-E2 Opener uses the high-speed reversing
action of an electric Gear Motor to provide an abrupt, forward-backward rocking (or
twisting action) to jog stubborn gates loose.
IMPORTANT
All persons involved in the installation,
operation, and maintenance of this equipment
should be thoroughly familiar with the contents
of this manual.

PH: 866.476.9217 5
When equipped with the Rolling Carriage option, the GO-E2 Opener can be mounted to
a steel W-Beam parallel to the track so the operator can roll the GO-E2 Opener from
gate to gate, and car to car. With the Rotating Platform option, the Opener can be
swung 180° to open the gates of rail cars on parallel tracks.
For hazardous atmospheres, ask your WORKMASTER Dealer about special models.

1. GEAR MOTOR
The GO-E2’s gear motor is an electrically powered unit with a cast iron housing
that can be mounted to a stationary object or to our Rolling Carriage. The GO-
E2’s drive shaft slides onto the motor’s keyed output drive.
2. ROTATING PLATFORM AND ROLLING CARRIAGE (RPRC)
The GO-E2’s RPRC is used in conjunction with a customer supplied W-Beam
(W8). The RPRC slides along the beam’s flange to better align the drive shaft
with the Railcars Capstan Socket. The RPRC also allows the operator to rotate
the motor and drive shaft 360 degrees for storage purposes or for opening on
both sides of the beam.
3. W-BEAM
We recommend a W8 Beam, as long as practical, to be mounted securely to the
ground roughly 7 feet from the inside edge of the inner rail. Although not
required to operate the GO-E2 (the motor can be mounted to a permanent
structure), the beam, in conjunction with the RPRC will maximize the Gate
Opener’s versatility.
4. ELECTRICAL CONTROL PACKAGE
The Electrical Control Package is wired for 480 V/3Ph/60Hz Operation. The
Package is specifically designed for remote operation and control of electric
motors in high voltage applications.
The Control Box features a NEMA-4 steel enclosure with continuous hinge and
cover clamps. This provides watertight protection of electrical controls.
The Terminal Board, mounted inside the control box serves as the central station
where power supply leads are connected.
The Reversing Magnetic Contactor, electrically and mechanically interlocked,
reverse the motor by electrically reconnecting the motor windings.
The Overload Relays trips power off when the motor stalls, or when it
experiences sustained overload or rapid cycling; the switch is manually reset
inside the control box.
A 120V, 2 AMP fused circuit runs from the control box to the hand-held pendant
control switch. This helps protect the operator by lowering the voltage in the
pendant control switch.

PH: 866.476.9217 10
A complete vinyl wiring diagram with adhesive backing, showing the motor
circuit and the control circuit, is permanently attached inside the control box.
The diagram offers a convenient reference for connecting circuits or
troubleshooting electrical problems.
5. PENDANT CONTROL
The Pendant Control is in a NEMA-4 (watertight) box and is operated by 2
momentary contact type pushbuttons. Wired to the Electrical Package with a
50ft cord, the Pendant Control allows the user to operate in both the clockwise
and counter-clockwise directions all while standing at a safe distance from the
railcar.
The Pendant Control is also equipped with a 2-position switch to energize and
de-energize the GO-E2’s motor
6. DRIVE TIP
The Drive Tip is secured to the Telescoping Drive Shaft (TDS) with a heavy-duty
set screw. The tapered end of the Drive Tip will firmly seat into the Railcar’s
Capstan Socket
REPLACEMENT DRIVE TIP PART # 33-10001
7. TELESCOPING DRIVE SHAFT (TDS)
The TDS connects the Drive Tip to the Gear Motor. By extending and
compressing the TDS allows the GO-E2 to accommodate traveling Capstan
Barrels. The U-Joint and Yoke design allows the Drive Tip to make full contact
with the Capstan Barrel at all angles.

PH: 866.476.9217 11
IV. INSTALLATION
1. Position the GO-E2's Gear Motor 7-feet from the inside edge of the inner rail.
If you have purchased the Beam Mount Assembly (BMA), secure a W-Beam
with at least a 6” width (W8 x 24) to the floor, 7-feet from the inside edge of
the inner rail. See Figure 1.
2. If you did not purchase the BMA, the Gear Motor to a base with enough
rigidity to prevent torsional or lateral vibratory flexure caused by dynamic
loading. The mounting surface should be flat, and clean, so stresses are not
induced during the mounting of the Gear Motor to its foundation.
Figure 2: Gear Motor Placement
3. The W-Beam should run parallel to the rails, along its entire length. The
GO-E2 will slide along this beam so the length is determined by your specific
application.
The W-Beam must be secured to the floor. If
not properly bolted the W-Beam and the
GO-E2 could topple over.

4. Once the W-Beam is secured, slide the BMA onto the beam so that the
beam's top flange fits into the t-slot on the bottom of the BMA.
5. Slide the carriage to a spot on the W-Beam where it will be convenient to
mount the Gear Motor. Once in position, lock the carriage in place by turning
the t-handle set screws clockwise.
6. Place the gear motor on top of the BMA and using the hardware supplied,
bolt the gear motor to the BMA.
7. With the Gear Motor completely secured, loosen the BMA's t-handle set
screws and slide the unit back and forth along the beam to verify ease of
movement.
8. Check the Gear Motor nameplate to verify that the phase, hertz and voltage
agree with the available power source.
CAUTION
The E2 Opener's Gear Motor is designed to
operate with the base mounted floor-
horizontal. Other special mountings require
modifications to the lubrication system and
seals. Consult your WORKMASTER Sales
Representative on special mountings.
CAUTION
Although the control package includes overload
protection, wiring the incorrect power supply
could still damage the Gear Motor. Ratings
cannot be exceeded.
It is the purchaser's responsibility to determine
the applicable local, state and national codes
related to electrical wiring of this unit.

PH: 866.476.9217 13
9. Wire the control package to the Gear Motor.
10. The GO-E2 Opener's Gear Motor is lubricated before shipment. Before start-
up (or prolonged storage), remove the seal from the breather/vent plug. The
lubricant level should be checked with the GO-E2 Opener mounted in its
correct position. Lubricant should be added or removed to bring it to the
correct level.
11. Test the Gear Motor by rotating the output shaft 360°.
12. Attach the motor-end yoke and Driveshaft assembly of the Telescoping
Driveshaft to the Gear Motor; align the connection using the key/keyway
provided on the Gear Motor, and firmly secure both set screws with a 3/16"
Allen wrench.
13. Locate and mount the Electrical Control Box. The Control Console is housed in
a NEMA-4 watertight steel enclosure with continuous hinge and cover clamps.
IMPORTANT
The Pushbutton Pendant Control Switch is
supplied with 50' of 18/4SOOW portable
cordage as standard.
IMPORTANT
A wiring diagram showing the motor circuit and
the control circuit is attached inside the Control
Box.

gate.
2. Once in position use the T-Handle set screws to secure the Gear Motor and
Rolling Carriage in place.
3. Disengage the Car Gate locking mechanism before attempting to open the
gate.
4. Using the Capstan Swage Tool (optional accessory PN: 33-11120), clean-out
and square-up the Capstan Socket on the Car Gate so that the Capstan Drive
Fitting on the GO-E2 Opener's Driveshaft can be properly and fully seated in
the car's Capstan Socket when opening the gate.
5. Extend and adjust the Telescoping Driveshaft until the Capstan Drive Fitting
on the yoke and tube assembly is firmly seated in the car's Capstan Socket.
6. Position yourself away from the Drive Shaft so that fingers, tools or articles of
clothing do not get caught during operation.
7. Press the "Forward" or "Reverse" momentary contact Pushbutton to open the
gate. If the gate is stuck, alternately press the "Forward" and "Reverse"
buttons to rock or jog the gate loose.
The Gear Motor must be securely fastened to its
foundation, and the rolling carriage must be
locked down before operating the GO-E2
Opener.
CAUTION
Failure to disengage the Car Gate locking
mechanism will cause damage to the Car Gate.

PH: 866.476.9217 15
8. Control the opening speed, and the travel of the gate so that it does not slam
against the end of the gate track.
9. If, after repeated attempts at "jogging" the Opener with the Pushbuttons, the
car gate will not move, STOP using the GO-E2 Opener and notify your
supervisor.
10. Remove the Capstan Drive Fitting from the Capstan Socket, collapse the
Telescoping Driveshaft, and secure the GO-E2 Opener for its next use.
Release the Pushbutton the moment the gate
reaches its fully opened position. Prolonged
hold down can cause the Driveshaft to slip from
the car's capstan and bounce uncontrollably
along the ground.
Do not use other opening devices, (pry bars,
multipliers, etc.) in a dangerous attempt to
"help" the GO-E2 Opener.
CAUTION
Do not hold either Pushbutton down for more
than a few seconds. Prolonged hold-down of
either button can cause the Gear Motor to
overheat and stall.
IMPORTANT
Handle the Telescoping Driveshaft carefully.
