The document provides safety training information for crane and hoist operators. It discusses qualifications required, daily inspection requirements, safety rules to follow during operation, and references various industry standards. The key points are:
- Operators must be qualified through training and pass a practical exam on the specific equipment.
- Daily inspections of hooks, wire ropes, brakes and other components are required to check for any defects or damage.
- Safety rules address proper load handling, not exceeding capacity, following signals, and shutting off power when not in use.
- References provided include ASME and OSHA standards on cranes, hoists, slings and other lifting equipment. Proper inspection and following industry
2. QUALIFICATIONS
• 11-3.1.3 Qualifications for Operators of
Floor-Operated Cranes or Carriers
• Personnel shall be required by the
employer to pass a practical operating
examination. Qualification shall be
limited to the specific type of
equipment for which examined.
4. All candidate for the Crane and Hoist operation job should be in the
interest of safety and be able to meet the minimum requirements
before being considered for training.
The basic requirements are as follows:
Must pass Hearing and Vision Testing per State Requirements.
5. Age
Most state laws, which govern the operations, require that a
person shall have passed their 18th
birthday before being
allowed to operate an overhead crane.
6. Vision
Standard visual acuity of 20/20 should be met. This can be
measured by a number of devices. Color vision should be
checked and field of vision should be determined.
7. .Reaction Time
Measures how quickly the person reacts to a set of signals or
to an emergency. (The Up Button sticks closed)
8. Distance Judgement
Measurement of depth perception is important for Crane
Operators.
Hearing
Several devices are available to test hearing ability. The
person should be able to meet standard requirements.
9. General Health
The company doctor should determine the physical fitness of the
individual. Any tendencies toward heart trouble, epilepsy, dizzy
spells, diabetes, high blood pressure, or physical defects should
be studied to determine physical fitness. If the doctor approves
of an individuals physical condition, the candidate should be
considered as having passed this phase of the requirements.
Physical Examination
A urinalysis and blood serology test should be given to every
candidate for a Crane Operator’s job. If the individual meets
standard requirements they can be considered as having passed
this phase of the requirements.
10. Literacy
Most state laws that govern the operations, site that an
individual must be able to read and write in English before
being allowed to operate an overhead crane.
This list is the minimum suggested requirements generally
recognized by most states.
11. SAFETY RULES
There are many safety rules that have been set up to be
observed by Crane Operators. However, if you follow these
rules you will observe most of the necessary precautions
while operating your crane.
.
12.
13. • THE OPERATOR MUST KNOW WHERE THE MAIN LINE
POWER DISCONNECT IS LOCATED.
• MAIN DISCONNECT MUST BE CLEARLY MARKED
AND FLOOR ACCESSABLE AND LOCKABLE
• On floor- or remote-operated cranes, a disconnect
device of the enclosed type shall be provided in the
leads from the runway conductors. This device should
be mounted on the bridge near the runway collectors.
14. 1. No one but a regularly authorized operator is
allowed to use any crane.
2. Before moving trolley or crane bridge, be sure that
the hook is high enough to Clear all obstacles.
15. 3. Under no circumstances permit your crane to
“bump” into
another crane or run the bridge or
trolley into end stops.
16. Do not run into the End Stops
On Top Running or Underhung
Cranes
18. Where the track is suspended from hanger rod
'assemblies, restraining means shall be provided to
prevent the hanger rod nuts from backing off the
hanger rods. AWAYS LOOK AT NUTS
19. 4. The operator SHALL NOT leave
their position at the
controls while a load is suspended.
20. • 5. Hoist Chains/Wire Rope SHALL NOT be
wrapped around the load. Slings must be
utilized.
21. • .6. Do not carry load over people on floor;
sound warning devices if crane is equipped to
warn persons nearby.
22. 7.
8.
9. 7. Do not allow anyone to ride on a load carried by the crane
or on the crane hook.
8. Do not drag slings, chains, or lifting devices out from
under loads that have been landed.
23. 9. If you are asked to do something that you DO NOT
believe is safe, you should refuse to do it and call your
foreman/supervisor in charge for advice.
10. An Operator MUST NOT operate a crane if he/she is not
physically fit to do so.
24. 11. Check all capacities for Max
load you can pick, “Never overload”
27. 12. In case of a problem always STOP operation
and open the power switch.
If your crane fails to respond correctly call your
foreman/supervisor.
Attempting to get out of difficulty by repeating the
operation may make the condition worse instead of
better
28. 13. When your crane is down for repairs,
assist the repairman. After completion of
any repair, make sure that bolts, tools, ect.
have been removed so that no injury to
personnel or damage to equipment will
result from falling objects when the crane
is returned to service.
29. 14. Never go on top of the crane or permit anyone else to do
so without opening the main switch and placing a warning tag
or lock on it. If you find a main switch with a warning tag or
lock DO NOT close the switch.
NOTE: Unless you are the one who opened the switch and
are absolutely sure there is no one on the crane or crane
runway.
30. • Crane operators must follow the
signals given to them only by
authorized persons (THE ASSIGNED
RIGGER) and should ignore
directions given by others during
operation of their equipment.
• The only EXCEPTION to this rule is
if ANYONE commands them to
EMERGENCY STOP.
• The operator should stay focused
of your surroundings-be aware of
any unusual sounds or warnings.
31. Cranes and Hoists are designed to make “Vertical
lifts” of loads ONLY.
DO NOT angle/side load unless it has been
determined by a qualified person not to pose a
hazard to equipment or personnel.
32. All employees are to read
B30.16
• Employer is to have a copy of the
manufacturers manual on site!
37. • THE HOIST DRUM WILL HAVE TWO FULL
WRAPS OF ROPE LEFT ON THE DRUM AT
THE LOWEST POSTION.
38. • LIMIT SWITHES ARE NOT USED AS A
OPERATING STOP.
• Limit switch - a switch that is operated by some
part or motion of a power-driven machine or
equipment to alter the electric circuit associated
with the machine or equipment.
43. Use of two Cranes
• (i) When two or more pieces of equipment
are used to lift a load, one qualified person
shall be in charge of the operation. This
person shall analyze the operation and
instruct all personnel involved in the
proper positioning and rigging of the load
and the movements to be made.
45. Load Marking
• 11-1.1.1 Rated Load Markings — Crane
• The rated load of the crane shall be marked on
the crane, and if the crane has more than one
hoisting unit, each hoist shall have its rated load
marked on the hoist or its load block so that the
rated load marking shall be legible from the
ground or floor. The combined load on all
hoists on the crane shall not exceed the
rated load of the crane.
46. OPERATION
• THE CAPACITY OF THE CRANE OR
HOISTING SYSTEM SHALL BE CLEARLY
MARKED ON EACH SIDE OF CRANE.
47. • WARNING DEVICES SHALL BE USED TO
WARN EMPLOYEES OF CRANE
MOVEMENTS.
• WARNING DEVICES ARE REQUIRED ON
CAB & REMOTE CONTROLLED CRANES.
Bells, Buzzers, Lights, Ect
48. • WHEN OPERATING A CRANE OR HOIST THE
OPERATOR WILL NEVER JOG OR REVERSE
THE LOAD TO CAUSE THE LOAD TO SWING
• MOVE TROLLEY OR BRIDGE TO MEET LOAD
AT SWING OF TRAVEL.
49. CHECKING THE LOAD AND
MOTOR BRAKES
• LIFT THE LOAD A FEW INCHES OFF THE GROUND.
Stop the lift and see if the load stops and holds.
• If the load keeps going, even if it is a few inches, the
motor brake is to loose and needs adjusted.
50. • ONLY LIFT THE LOAD HIGH ENOUGH TO CLEAR ANY OBJECT
IN YOUR PATH.
• NEVER EXCEED THE LOAD RATING ON YOUR SYSTEM.
• Must be clearly marked on each side of Beam
• When load is lifted over 5 feet, head protection is required.
• Operators should be trained in the use of fire extinguisher
51. KNOW THE LOAD
• THE OPERATOR IS NEVER TO EXCEED THE
CAPACITY OF THE CRANE.
• Look on shippers tag for the weight or weigh the
item on shipping scale
• If unsure always ask !
54. • Daily inspections shall be performed by the
crane operator prior to beginning shift and
through observation during normal
operation.
