INTRODUCTION
Thank you for choosing a Gorbel® Retrofit II to solve your material handling needs. The innovative design and
heavy-duty construction of a Retrofit II added to an existing jib will provide a superior quality product that will offer
years of long term value. All Gorbel® cranes are pre-engineered for powered hoist operation. The hoist weight
allowance is 15% of the crane capacity (for example, a crane rated for 1000 pounds allows for a 1000-pound live
load plus 150 pounds for the weight of the hoist). There is also an allowance of 25% of the crane capacity for
impact caused by hoist use. Gorbel® Free Standing Jib Cranes will provide many years of dependable service by
following the installation and maintenance procedures described herein.
Dimensions contained in this installation manual are for reference only and may differ for your particular
application.
Normal safety precautions: These include, but are not limited to:
• Checking for obstructions in crane rotation
• Checking that all bolts are tight and have lockwashers
• Making sure that endstop is in place
• Making sure that festooning cannot be snagged or pinched
For additional safety precautions see page 12.

STEP 3A - ELECTRIFICATION INSTALLATION (STANDARD DRIVE)
JIB DRIVE CONTROLLER
Jib rotation control is by magnetic reversing starters. For troubleshooting and general
informattion, a brief summary is included below. Other controllers may be available. See the
appropriate enclosed insert for any optional equipment where applicable.
SINGLE SPEED OPERATION
Single speed operation utilizes the drive ratio of the reducer and the ratio of the drive to driven
sprockets to produce the standard jib rotation speed. These ratios are determined by the crane
parameters (span, capacity, indoor, outdoor, etc.).
Materials typically contained within the electrical enclosure are as follows:
• Mainline Fuseblock
• Branch Fusing (Hoist)
• Control Transformer
• Terminal Strip
• Reversing Starters
• Thermal Overloads
• Mainline Contactor
STEP 3B - ELECTRIFICATION INSTALLATION
(VARIABLE FREQUENCY CONTROL DRIVE)
JIB DRIVE CONTROLLER
The drive controller for the jib drive is pre-programmed at Gorbel for single speed, two speed, or
three speed operation. For troubleshooting and general information, a brief summary of how the
drive controller is designed to be used is included below. No additional programming is required.
All options utilize an adjustable speed controller.
SINGLE SPEED OPTION
This option utilizes the drive ratio of the reducer and the ratio of the drive to driven sprockets to
produce the standard jib rotation speed. These ratios are determined by the crane parameters
(span, capacity, indoor, outdoor, etc.). The drive controller is then programmed for the motor to
operate at normal speed (60 Hz).
TWO SPEED OPTION
This option varies the motor speed to determine the desired jib drive speeds. The motor
controller is then programmed for the motor to operate at two different percentages of full speed
based on the desired speeds specified by the customer at the time the order is placed.
WARNING
The drive controller drive must only see its own internal voltage and not be connected to an external voltage source.
Allowing 24 or 120 control voltage to go through the drive will PERMANENTLY DAMAGE the internal controls!
47/2022

STEP 3B - ELECTRIFICATION INSTALLATION
(VARIABLE FREQUENCY CONTROL DRIVE) (CONTINUED)
THREE SPEED OPTION
This option is similar to the two speed option listed above. The motor controller is programmed
for the motor to operate at three different percentages of full speed based on the desired speeds
specified by the customer at the time the order is placed.
DRIVE CONTROLLER PROGRAMMING
Gorbel pre-programs a number of parameters in the drive controller prior to shipment. The
remaining parameters are left at the factory default settings. All parameters are stored on the
EPM module. These parameters are as follows:
Preset speeds 2 & 3 are used only if required for two or three speed drives.
Parameter 50 contains the fault history of the last eight (8) faults with the most recent first.
Pressing the “Mode” button three times will access this parameter.
Deceleration time: The deceleration time is factory set at 4 seconds. This can be adjusted to a
shorter time period with the following warning. If the deceleration time is set to too short a time
period, the drive controller will shut down and show an alarm. This is the result of the jib crane
having too much inertia for the reducer and motor to stop in such a short time. If this occurs,
increase the deceleration time.
WARNING
Do not remove or install the EPM module while power is applied to the drive controller. After removing power from
the drive controller, wait three (3) minutes before removing the EPM module for the capacitors to discharge.

36 Preset Speed 3 Preset Speed 3 As required (0-60 Hz)

STEP 4 - LIMIT SWITCH INSTALLATION
If applicable, install limit switches per the following instructions and diagram 4A on page 8.
The limit switches are designed to shut off the power to the rotation drive motor in a clockwise or
counterclockwise direction and are not intended to serve as a spotting function.
Two limit switches are mounted on the channel attached to the main frame. Each switch has an
adjustable roller-type lever arm and is actuated by a limit switch ramp that must be attached to
the mast pipe. The limit switch ramps must be field located, by the installer, to shut off power at
the desired clockwise and counterclockwise points. The switches (optional) are pre-wired into
the control panel of the jib crane and require no additional electrical hook-up.
SWITCH ADJUSTMENT:
After the jib crane has been erected and the safety channel, with the two limit switches, has been
installed, the switch set-up is as follows:
1. Loosen the hex socket screw that locks the adjustable lever arm in position.
2. Loosen the lock pin hex nut that fastens the lever arm assembly to the limit switch.
3. Rotate the lever arm until it is perpendicular to the face of the mast pipe and then rotate it an
additional 15° away from the side that will contact the limit switch ramp (15° counterclockwise
for the upper limit switch and 15° clockwise for the lower limit switch). The additional 15° will
prevent jamming of the lever arm when the lever arm contacts the limit switch ramp.
4. Adjust the roller so that it has a 1/8” maximum clearance to the face of the mast pipe.
5. Retighten both the hex socket screw and the lock pin hex nut.
6. Rotate the jib crane 360° and check to see if the roller comes in contact with the mast pipe.
If the roller contacts the mast pipe, increase the clearance between the roller and the pipe
until it does not.
7. Repeat this procedure for the second limit switch.
67/2022

STEP 4 - LIMIT SWITCH INSTALLATION (CONTINUED)
RAMP INSTALLATION:
Two rotation limits can be established, one in the clockwise direction and one in the counter-
clockwise direction. The lower switch will be the clockwise rotation limit switch and the upper
switch will be the counterclockwise rotation limit switch. Do not reverse the functions of the
upper and lower limit switches. Reversing the functions may cause the limit switch lever arm
to hit the limit switch mounting bracket.
Clockwise Rotation Limit Switch Ramp Installation:
1. Place the jib in its’ clockwise limit position.
2. Position a limit switch ramp, with the beveled edge facing the switch lever arm roller, on the
mast pipe to the left of the lower switch.
3. Slide the limit switch ramp along the surface of the mast pipe, into the roller lever arm
causing the lever arm to move. Stop moving the ramp when an audible click is heard from
the switch.
4. Drill and tap two (2) 1/4”-20 holes in the mast pipe centered in the two slots in the limit switch
ramp.
5. Secure the limit switch ramp to the mast pipe using the (2) tapped holes and the 1/4”-20
hardware provided.
6. Adjust the limit switch ramp location to compensate for over travel (see the over travel
adjustment instructions on page 8.
Counterclockwise Rotation Limit Switch Ramp Installation:
1. Place the jib in its’ counterclockwise limit position.
2. Position a limit switch ramp, with the beveled edge facing the switch lever arm roller, on the
mast pipe to the right of the upper switch.
3. Repeat Steps 3 through 6 from “Clockwise Rotation Limit Switch Ramp Installation”
instructions.
7
7/2022

STEP 4 - LIMIT SWITCH INSTALLATION (CONTINUED)
Over Travel Adjustment Instructions:
All cranes will experience some over travel, after power to the drive is shut off, due to inertia of
the load acquired during rotation. The amount of over travel is dependent on the application and
the size of the jib crane. In order to accurately compensate for over travel, it is necessary to test
the rotation performance of the jib under full load and determine the actual over travel.
1. With the hoist at the end of the boom, lift a capacity load up one half the distance from the
floor to the hoist.
2. Push the “ON” button to power controls.
3. Start rotating jib crane in the direction of the previously installed limit switch ramp. It is
important to give the jib crane enough
starting distance before the ramp to
accelerate to full speed.
4. When the limit switch reaches the
desired rotation limit position, the lever
arm will contact the ramp and the
power to the motor will be shut off.
Allow the jib crane to come to a full
stop.
5. Measure the distance between the
beveled edge of the ramp and the
centerline of the roller on the switch
arm.
6. Loosen the 1/4”-20 hardware holding
the limit switch ramp to the mast pipe
and slide the ramp towards the lever
arm roller the distance measured in
Step 5.
7. Retighten the 1/4”-20 hardware to hold the limit switch ramp into place on the mast pipe.

STEP 5 - ENDSTOP/TAGLINE INSTALLATION
Tagline Festoon Installation - Where Applicable (diagram 5A)
5.1 Bolt tagline bracket and an endstop to end of boom closest to the mast.
5.2 Reinstall existing hoist/hoist trolley into place (where applicable).
5.3 Immediately bolt remaining tagline bracket and endstop into place at the front of boom.
Torque nuts.
5.4 Bolt eyebolts to tagline brackets using two hexnuts per eyebolt.
5.5 Loop the wire rope through one of the eyebolts and clamp the loop using cable clamps.
Repeat this step at the other eyebolt while removing any slack from the wire rope.
5.6 Adjust the eyebolts to achieve the desired cable tension and lock the eyebolts in place by
tightening the hexnuts.
5.7 Run the festoon cable through the S-hooks or wire rope trolleys (squeeze bottom of
S-hooks to grip cable or hose).
5.8 Wire the hoist per manufacturer’s (SIC) instructions.

STEP 6 - SHUT-DOWN INSTRUCTIONS
6.1 Secure the beam in shut-down position or storage area. Check crane, hoist and hook
storage positions to be sure there is no interference with other pieces of equipment that
may be operating in the area.
6.2 If crane is electrified, shut power OFF on pendant and disconnect switch. Make sure there are
not any damaged wires and all of the connections are tight. Make a visual check before leaving
area.
STEP 7 - FINAL STEPS
7.1 Check to make sure all bolts are tightened and lockwashers are compressed.
7.2 If necessary, touch up with paint provided.
7.3 Keep Packing List, Installation Manual, General Arrangement Drawing and any other
inserts together in a safe place.
SAFETY WARNINGS AND PRECAUTIONS
Safety is very important when operating a jib crane. There are many safety warnings and
precautions the operator should be aware of. These include, but are not limited to, the following:
• The jib can only be used to pick up a MAXIMUM of RATED CAPACITY.
• The load will swing when lifted.
• Make sure the power is “OFF” prior to doing any electrical work or checking wires and connections.
• When loading, pick load directly up. Crane should not be used to pick up a load diagonally or
out of the range of the span.
• On all baseplate mounted cranes, periodically check anchor bolts to make sure they are tight.
• Watch for wet spots: oil, water, etc. where the operator may slip.
• Check that all bolts are tight and have lockwashers.
• Make sure endstops are in place, are fully engaging the trolley and the endstop hardware is tight.
• Make sure that festooning cannot be snagged or pinched.
• Check for obstructions in crane travel.
• The operator should have full concentration on the crane and its surroundings at all times.

CRANE OPERATOR INSTRUCTIONS
Overhead cranes and jib cranes generally handle materials over working areas where there are personnel. Therefore, it is important for the Crane Operator to be
instructed in the use of the crane and to understand the severe consequences of careless operation.
It is not intended that these suggestions take precedence over existing plant safety rules and regulations or OSHA regulations. However, a thorough study of the
following information should provide a better understanding of safe operation and afford a greater margin of safety for people and machinery on the plant floor.
It must be recognized that these are suggestions for the Crane Operator’s use. It is the responsibility of the owner to make personnel aware of all federal, state and
local rules and codes, and to make certain operators are properly trained.
Qualifications
Crane operation, to be safe and efficient, requires skill: the exercise of extreme care and good judgment, alertness and concentration, and rigid adherence to proven
safety rules and practices as outlined in applicable and current ANSI and OSHA safety standards. In general practice, no person should be permitted to operate a
crane:
• Who cannot speak the appropriate language or read and understand the printed instructions.
• Who is not of legal age to operate this type of equipment.
• Whose hearing or eyesight is impaired (unless suitably corrected with good depth perception).
• Who may be suffering from heart or other ailments which might interfere with the operator’s safe performance.
• Unless the operator has carefully read and studied this operation manual.
• Unless the operator has been properly instructed.
• Unless the operator has demonstrated his instructions through practical operation.
• Unless the operator is familiar with hitching equipment and safe hitching equipment practices.
Handling the Jib Boom Motion
Before using the boom of the jib crane, the operator should be sure the hook is high enough to clear any obstruction. Before a load is handled by the crane, the jib
boom should be brought into position so that it is directly over the load. Start the jib boom slowly and bring it up to speed gradually. Approaching the place where it is
desired to stop the jib, reduce the boom speed.
Handling the Trolley Motion
Before a load is handled, the hoist should be positioned directly over the load that is to be handled. When the slack is taken out of the slings, if the hoist is not directly
over the load, bring it directly over the load before hoisting is continued. Failure to center the hoist over the load may cause the load to swing upon lifting. Always
start the trolley motion slowly and reduce the trolley speed gradually.
Handling the Hoist Motion
Refer to the lifting (hoist) equipment’s operating instructions.
GENERAL SUGGESTIONS
Know Your Crane
Crane operators should be familiar with the principal parts of a crane and have a thorough knowledge of crane control functions and movements. The crane operator
should be required to know the location and proper operation of the main conductor disconnecting means for all power to the attachments on the crane.
Responsibility
Each crane operator should be held directly responsible for the safe operation of the crane. Whenever there is any doubt as to SAFETY, the crane operator should
stop the crane and refuse to handle loads until: (1) safety has been assured or (2) the operator has been ordered to proceed by the supervisor, who then assumes all
responsibility for the SAFETY of the lift.
Do not permit ANYONE to ride on the hook or a load.
Inspection
Test the crane movement and any attachments on the crane at the beginning of each shift. Whenever the operator finds anything wrong or apparently wrong, the
problem should be reported immediately to the proper supervisor and appropriate corrective action taken.
Operating Suggestions
One measure of a good crane operator is the smoothness of the crane operation. The good crane operator should know and follow these proven suggestions for
safe, efficient crane handling.
1. The crane should be moved smoothly and gradually to avoid abrupt, jerky movements of the load. Slack must be removed from the sling and hoisting ropes
before the load is lifted.
2. Center the crane over the load before starting the hoist to avoid swinging the load as the lift is started. Loads should not be swung by the crane to reach areas
not under the crane.
3. Crane-hoisting ropes should be kept vertical. Cranes shall not be used for side pulls.
4. Be sure everyone in the immediate area is clear of the load and aware that a load is being moved.
5. Do not make lifts beyond the rated load capacity of the crane, sling chains, rope slings, etc.
6. Make certain that before moving the load, load slings, load chains, or other lifting devices are fully seated in the saddle of the hook with hook latch closed (if
equipped with hook latch).
7. Check to be sure that the load and/or bottom block is lifted high enough to clear all obstructions when moving boom or trolley.
8. At no time should a load be left suspended from the crane unless the operator has the push button with the power on, and under this condition keep the load as
close as possible to the floor to minimize the possibility of an injury if the load should drop. When the crane is holding a load, the crane operator should remain
at the push button.
9. Do not lift loads with sling hooks hanging loose. If all sling hooks are not needed, they should be properly stored, or use a different sling.
10. All slings or cables should be removed from the crane hooks when not in use (dangling cables or hooks hung in sling rings can inadvertently snag other objects
when the crane is moving).
11. Operators shall not carry loads and/or empty bottom blocks over personnel. Particular additional caution should be practiced when using magnet or vacuum
devices. Loads, or parts of loads, held magnetically could drop. Failure to power magnets or vacuum devices can result in dropping the load. Extra precaution
should be exercised when handling molten metal in the proximity of personnel.
12. Whenever the operator leaves the crane the following procedure should be followed:
• Raise all hooks to an intermediate position.
• Spot the crane at an approved designated location.
• Place all controls in the “off” position.
• Open the main switch to the “off” position.
• Make visual check before leaving the crane.
13. In case of emergency or during inspection, repairing, cleaning or lubrication, a warning sign or signal should be displayed and the main switch should be locked
in the “off” position. This should be done whether the work is being done by the crane operator or by others.
14. Contact with rotation stops or trolley end stops shall be made with extreme caution. The operator should do so with particular care for the safety of persons
below the crane, and only after making certain that any persons on the other cranes are aware of what is being done.
15. ANY SAFETY FEATURES AND MECHANISMS BUILT-IN OR OTHERWISE PROVIDED WITH THE CRANE BY GORBEL ARE REQUIRED FOR THE SAFE
OPERATION OF THE CRANE. DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE OR OTHERWISE IMPAIR OR DISABLE THE PROPER FUNCTIONING
OF ANY CRANE SAFETY MECHANISMS OR FEATURES BUILT-IN OR OTHERWISE PROVIDED BY GORBEL FOR SAFE OPERATION OF THE CRANE.
ANY REMOVAL, IMPAIRMENT OR DISABLING OF ANY SUCH SAFETY MECHANISMS OR FEATURES OR OTHER USE OR OPERATION OF THE CRANE
WITHOUT THE COMPLETE AND PROPER FUNCTIONING OF ANY SUCH SAFETY MECHANISMS OR FEATURES AUTOMATICALLY AND IMMEDIATELY
VOIDS ANY AND ALL EXPRESS AND IMPLIED WARRANTIES OF ANY KIND OR NATURE.
TIP: Be sure your installers, maintenance personnel, and operators realize this jib can only be used to pick up a maximum
of its rated capacity.

Securex Friction Torque Limiter Type C & T
Installation & Maintenance Instructions (Size 30 Thru 280)
•Read and follow all instructions carefully.
•Disconnect and lock-out power before installation and maintenance. Working on or near
energized equipment can result in severe injury or death.
•Do not operate equipment without guards in place. Exposed equipment can result in severe
injury or death.
•Periodic inspections should be performed. Failure to perform proper maintenance can
result in premature product failure and personal injury.
•All electrical work should be performed by qualified personnel and compliant with local and
national electrical codes.
GENERAL
Before assembly, the pressure plates, facings, and center member (sprocket, sheave, plate,
etc.) should be free of oil, grease, dirt, and rust. The center member should have a 1.6-micron
finish on the area where the friction facings rub to obtain maximum rated capacity and optimum
life from the Torque Limiter.
ASSEMBLY
Refer to the appropriate sketch (see below) and assemble on the torque limiter hub the following:
(A) Friction facing (B) Bushing (C) Center member (not shown) (D) Friction facing (E) Pressure
plate (F) Spring(s) (G) Pilot plate (95 to 170 size models only) or (H) Lock washer (30 to 85 size
models only) (J) Adjusting nut. When assembling the friction torque limiter type C, please refer to
the extra notes below.

RUNNING- IN
Torque Limiters should be run-in for the most consistent results. To run-in, adjust the Torque
Limiter to 25% of the maximum single spring capacity and slip the center member approximately
50 RPM for approximately 4 minutes.
TORQUE SETTING PROCEDURES
Type 30 ÷ 85: Loosen the locking screw (A) and tighten the adjusting nut with the proper
spanner or hook wrench until a slight contact with the spring is established. Then tighten the
adjusting nut further to obtain the pressure necessary to transmit the required torque without
slipping. Now check if slip occurs at the required torque value and then tighten the locking
screw. After the slip torque preset, the nut is locked in position by means of the appropriate
locking washer.
A
SIZE 40-85
SIZE 30

Type 95 ÷ 170: slip torque is preset by adjustment of 4 or more screws on the nut (B), providing
axial load to the disk spring. This system makes the adjustment easy. Apply springs load by
loosening the adjusting bolts in approximately 60 degrees steps until no slip is observed under
maximum load conditions in normal running mode. It is essential that all the bolts have equal
adjustments or damage to friction facings will occur. The available diagrams give the
approximate slipping torque in function of the number of turns of the adjusting bolts (the fraction
refers to the number of faces of the bolts.
Example: (2/6 means turn 2 out 6 faces present on the bolt).
B
SIZE 95-170
Type 200 AND UP: These larger units have a series of smaller disc springs mounted on threaded
holding pins which are threaded into the adjusting nut (D). Loosen the spring holding pins (C)
and make pre- adjustment of the adjusting nut. Wind the adjusting nut by hand until tight against
pilot plate. Ensure friction facing are concentric on the bushing and that the springs are correctly
positioned on the pins.
Start tightening spring holding pins up to minimal spring resistance is observed. Then, apply
springs load by tightening the adjusting bolts in approximately 60 degrees steps until no slip is
observed under maximum load conditions in normal running mode. It is essential that all the
bolts have equal adjustments or damage to friction facings will occur. The available diagrams
give the approximate slipping torque in function of the number of turns of the adjusting bolts
(the fraction refers to the number of faces of the bolts. Example: 2/6 means turn 2 out 6 faces
present on the bolt).
Having set the torque limiter as outlined above, it is common practice to advance the bolts a
further 60 degrees to prevent excess on machine start-up. Lock the nut by tightening the two
screws located in it.
SIZE 200-280 D
C

TORQUE CHECKING
To check the Torque Limiter for the required slip torque, mount the Torque Limiter on a stub
shaft and fasten in a bench vise. Wrap the center member (if a sprocket) with a chain and load
the chain with weights until the center member rotates. If the center member is a plate, attach a
chain or cable to the center member. The breakaway torque will be equal to the radius of the
center member in feet times the weight in lbs. on the chain. The breakaway torque should be
slightly higher (5% to 10%) than the required slip torque. If the slip torque is too high or too low,
readjust torque limiter as per torque setting procedures above. After readjustment, check the
breakaway torque in the manner outlined above and repeat adjustments is necessary
MAINTENANCE:
The Securex series torque limiters do not normally require any maintenance. However, as with
all friction torque limiters, regular inspection of the friction surfaces and other related
components is highly recommended. The friction pads should be replaced when they have
each worn to half of their original, new thickness. At periodic intervals, or if proper torque is not
being maintained, inspect Torque Limiter for presence of oil, grease, moisture, or corrosion on
the driving surfaces and for proper setting of spring load. Clean and adjust as required. Friction
facings and bushings are the only parts that should normally require replacement.
CAUTION
The operating characteristics and capacity of Torque Limiters are affected by atmospheric
conditions, moisture, lubricants, and surface corrosion. To illustrate, the life of the friction facings
may be greatly reduced by rust on the center plate. The Torque Limiter ratings are based on
average conditions. For best results, the Torque Limiter should be adjusted under conditions like
those in which it will be used.
HOW TO REPLACE FRICITON DISCS
Please refer to the appropriate sketch (see above).
1. Remove the drive chain/belt from the torque limiter center member.
2. Loosen Adjusting nut (J)
3. Disassemble all components in the following order: Remove (G) Pilot plate (95 to 170 size
models only) or (H) Lock washer (30 to 85 size models only), (F) Spring(s), (E) Pressure plate,
(D) Friction facing, (C) Center member (not shown), (B) Bushing, and (A) Friction facing
4. Reassemble by placing new friction discs on both sides of a new sprocket and a new
sintered bushing. Please refer to the assembly instructions above.
