INTRODUCTION
Thank you for choosing Gorbel® to solve your material handling needs. The innovative design and heavy-duty
construction of the Gorbel® product will provide a superior quality product that will offer years of long term value.
The hoist weight allowance is 15% of the crane’s capacity (for example, a crane rated for 6000 pounds, allows for a
6000-pound live load plus 900 pounds for the weight of the hoist). There is also an allowance of 15% of the crane
capacity for impact caused by hoist use. Gorbel® products will provide many years of dependable service by
following the installation and maintenance procedures described herein.
Gorbel® products are shipped in various stages of assembly and are installed under varying circumstances. As a
result, a complete guide with descriptions covering all variations is not possible. The following instructions are only to
be used as a general guide. Attention should be paid to the warnings and safety suggestions posted in this manual
and on the equipment.
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 travel
• Checking that all bolts and threaded rods are tight and have lock washers where applicable
• Making sure that end stops are in place and functional (i.e. stopping rolling equipment from exiting rail)
• Making sure that festooning cannot be snagged or pinched, whether it is electric or pneumatic
• For additional safety precautions, see page 19.

CRANE OPERATOR INSTRUCTIONS
Overhead Patented Track 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 judgement, 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 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 the 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 of power to 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 CLEVELAND TRAMRAIL 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 CLEVELAND TRAMRAIL 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.

PERIODIC INSPECTION AND LUBRICATION RECOMMENDATIONS
The following is a checklist to be followed in performing periodic inspections and preventative
maintenance on Gorbel® Tarca® Systems. It is intended that this checklist be supplemented with
any additional instruction sheets and maintenance manuals sent with each job.
The frequency of inspection and lubrication recommendations presented herein is based upon
normal operating conditions of one complete handling cycle every 10 minutes throughout a
40-hour week. If the actual duty cycle of a particular unit is greater or less than this, the inspections and lubrications should be performed more frequently or less frequently in proportion.
Each industry has conditions peculiar to it, which may cause wear of certain parts. The tabulation
given is only general and may be supplemented by an individual maintenance department
program to meet its own particular requirements. Particular attention should be given to corrosive
conditions, excessive vibrations, extreme ambient temperature variations, and rough handling
conditions.
Questions regarding damaged, worn or cracked equipment components should be directed to
the Gorbel® Customer Service Department at 800-821-0086 or 585-924-6262.
The recommendations contained herein are to be supplemented by any vendor instructions,
which are included in this manual.
WARNING: Power should be off and locked when performing maintenance on any part of the
