4. . DEFINITIONS
AUTHORIZED: IS ONE APPOINTED OR
CREDENTIALLED BY A DULY CONSTITUTED
ADMINISTRATIVE OR REGULATORY
AUTHORITY
5. Competent Person
A competent person is one who by knowledge, training and
experience has demonstrated the ability to solve problems
and preform functions relating to the subject matter and
work
13. 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.
16. 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.
.
17. 1. No one but a regularly authorized operator is
allowed to use any crane.
2. Load Rating Chart with clearly legible letters and
figures shall be provided and fixed to the crane. Must
be clearly visible to operator at there controls
3. Before moving crane, be sure that the hook is high
enough to Clear all obstacles.
18. 4. The operator SHALL NOT leave their position at the
controls while a load is suspended.
5. The Cranes Wire Rope SHALL NOT be wrapped
around. the load. Slings must be utilized
6. Do Not carry load over people on floor; sound warning
devices if crane is equipped to warn persons nearby.
19. 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
20. 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.DO NOT exceed the rated capacity of your Hoist/Crane
11. An Operator MUST NOT operate a crane if he/she is not
physically
fit to do so.
21. 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
22. 15. 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.
25. Crane Hand Signals # 3
Emergency Stop------------------------------------- Routine Stop------------
26. Who can give the hand signals? or
Who can be a signaler?
a person qualified to give crane signals to
the operator, there should be only one
designated signaler at a time, if signalers
are changing between each other, the one
in charge should wear a clearly visible
badge of authority, a crane operator
should move loads only on signals from
one signaler, a crane operator must
obey STOP signals no matter who
gives it.
27. DON’T BE A HEADLINE
SUMMARY
Every worker should know crane hand signals. Knowing
the signals may allow you to help out when needed If
you are asked to be a signal person, make sure you are
using the same signals as other workers and operators
on the project When tower cranes or situations where
hand signals are not safe enough, ensure that a two-way
radio is used for voice communication. This will give you
direct contact with the operator. Whatever system you
use - hands or radio - make sure the equipment and
workers are able to do the job right.
Don't Be a Headline
28. Cranes
Cranes 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.
29. Limit Devices
A limiting device shall be installed and
maintainted to prevent the hook or other
end fitting from contacting the upper
sheaves.
30. Booms
When sections of booms are added or
removed, full number of bolts or pins of
the material and size recommended by the
manfacture
31. Fire Extinguishers
(i) A carbon dioxide, dry chemical, or
equivalent fire extinguisher shall be kept in
cab or vicinity of the crane
(ii) Operating and maintenance personal
shall be made familiar with the use and
care of the fire extinguishers provided.
33. Load Rating
Load ratings - where stability governs lifting
performance."
1910.180(c)(1)(i)
The margin of stability for determination of load ratings,
with booms of stipulated lengths at stipulated working
radii for the various types of crane mountings, is
established by taking a percentage of the loads which
will produce a condition of tipping or balance with the
boom in the least stable direction, relative to the
mounting. The load ratings shall not exceed the following
percentages for cranes, with the indicated types of
mounting under conditions stipulated in paragraphs (c)
(1)(ii) and (iii) of this section. Truck cranes 85%
34. 1910.180(c)(2)
"Load rating chart." A substantial and durable
rating chart with clearly legible letters and figures
shall be provided with each crane and securely
fixed to the crane cab in a location easily visible to
the operator while seated at his control station.
