Dear friend,
It is best to remember that only a competent person can inspect a crane. The definition for competent person is known to every one in the profession.
There are very many types of cranes. Crane inspection is a specialization. A competent mechanical engineer who specializes in cranes alone can do the inspection. In fact crane inspection itself is a profession now. Even the “specialist crane inspector” can not conduct an inspection unless he goes through the manual. My feeling is that if you are a professional crane inspector you would not have asked for pps on crane inspection. Where do you stand ?
Next step is daily inspection. This is done by the operator. He inspects the crane daily. He checks the crane visually and functionally and makes a report to his reporting officer. If there is any defect that affects the safety or functioning of the crane it will be rectified immediately for him to use the crane.
A sample daily inspection checklist is attached for reference.

Dear Ashok
Kesava sir has already given you a great reply to your query... Let me add my experience regarding how I learn the bascis of Crane Operation and Inspection... You may also do the same to get a clear understanding regarding crane...
I take the checklist of Crane Inspection with me and approch to the Service Engineer of the Crane who came for assembling new crane in our plant... Ask him each and every term in the checklist and learn...
In similar way you take a printout of the Checkilist which is given by Kesava sir and go to field... Take you Mech. Engg and the Crane Operator with you... Surely you will learn a lot, which you may even not find out in any presentations...
Once again thanks Kesava Pillai sir for sharing your expertise with us... Keep on guiding us...

Lets i have to add something related to this thread..
MOBILE CRANE OPERATIONS—WHO IS RESPONSIBLE?
The question of who is responsible for the various aspects of a crane operation is too often Unclear until a serious accident occurs and a court decides.
Because most crane operations are complex and because they can differ so much from one job to the next, no single set of guidelines can ever cover all the parameters involved. The following information, however, can be applied to most situations.
CRANE SUPERVISOR
The crane SUPERVISOR is responsible for the identification and assignment of specific responsibilities to the operating crew. The SUPERVISOR must be aware of the requirements of every job.
1. ensuring that the crane has the rated capacity necessary for the job.
2. ensuring that the operator is well trained, licensed where required, experienced, and competent to operate the particular crane to which they are assigned on the particular job involved.
3. ensuring that the operator is fully aware of their responsibilities and expectations and capable of carrying them out.
4. providing ongoing, high-quality training and upgrading programs for all personnel to ensure a consistently high level of competence in all phases of the operations.
5. assigning to the crew clear individual responsibilities and the authority necessary to exercise the responsibilities.
6. providing qualified supervision for the operation where needed.
7. ensuring the crane is used in accordance with the manufacturers’ instructions and all applicable regulations.
8. ensuring that the log book is maintained and updated.
Many accidents that are attributed to operator error are often not the operator’s responsibility. Inadequate planning on the part of site supervision often puts crane operators in the position of having to make judgements or decisions that are beyond what should be reasonably expected of them.
Generally, the operator is responsible for the safety of the crane operation as soon as the load is lifted clear of the ground. Because of this responsibility, whenever there is reasonable cause to believe that the lift might be dangerous or unsafe, the operator must refuse to lift until the concern has been reported to the supervisor, any hazards are rectified, and safety conditions are met.
The operator is specifically responsible for
1. knowing the machine well. The operator must understand its functions and limitations as
well as its particular operating characteristics.
2. having a thorough knowledge of the information contained in the crane's operating
manual.
3. being familiar with the crane's load chart. The operator must understand the correct
meaning of all notes and warnings and be able to calculate or determine the crane's actual
net capacity for every possible configuration of the machine.
4. inspecting and maintaining the crane regularly as prescribed by both the owner and
manufacturer.
5. informing the owner of any problems, needed maintenance, or necessary repairs to the
machine. This should be done in writing, preferably in the machine's logbook or
inspection report.
6. recording in the log or report the details of all inspections, maintenance, and other work
done on the crane while in the field.
7. supervising and training the apprentice if one is present.
8. being aware of any site conditions that could affect the crane operation. Be particularly
cautious around powerlines. The operator must refuse to operate if the crane, hoist rope,
or load will come closer to a powerline than the absolute limit of approach specified in
law.
9. checking that the site is adequately prepared for the crane.
10. reviewing the planned operation and requirements with the site supervision.
11. finding out the load and rigging weight and determining where the load is to be placed.
Although the operator is not responsible for determining the weight of the load, if the
operator lifts it without checking the weight with site supervision, then the operator
becomes fully responsible for the lift and any consequences that result. 12. determining the number of parts of hoist line required.
13. checking the load chart to ensure that the crane has sufficient net lifting capacity for
every lift.
14. selecting (from the range diagram) the best boom, jib, and crane configuration to suit the
load, site and lift conditions.
15. assembling, setting up and rigging the crane properly.
16. following the manufacturer's operating instructions in accordance with the load chart.
17. considering all factors that might reduce crane lift capacity and adjusting the load weight
to suit. This will include such factors as weather conditions and ground conditions.
18. knowing basics of rigging procedures and ensuring that they are applied (this is possible
only when the load is visible to the operator).
19. maintaining communication with signalpersons.
20. ensuring that the apprentice is in a safe place during operation.
21. operating in a smooth, controlled, and safe manner.
22. moving the crane.
23. shutting down and securing the machine properly when it is unattended.
24. exercising the right to refuse to operate the crane if there is cause to suspect the lift might
be unsafe.
SITE SUPERVISION
Site supervision has overall responsibility for the lift. Supervision must plan all phases of
operation, cooperating fully with the operator who has the final say regarding the safety of the
operation.
Site supervision is specifically responsible for
1. verifying that the crane certification and inspection records are up to date before allowing the
crane on the project.
2. organizing a pre-lift meeting and ensuring all the appropriate people are present.
3. establishing a lift plan and ensuring it is followed.
4. providing a well prepared working area for the crane before it arrives on the job. This
involves ensuring that
a) access roads are adequately prepared.
b) there is room to erect and/or extend the boom.
c) blocking is available to support the boom while it is being assembled and dismantled.
d) operating locations are graded, level, and compacted.
e) blocking is always used under outriggers.
f) the crane supplier will be told if the ground is soft and if hardwood mats or cribbing are
needed.
g) operating locations are far enough away from shoring, excavations, trenches, buried
utilities, foundations, etc. to eliminate the risk of collapse.
h) operating locations are chosen to ensure the minimum clearances from powerlines.
Otherwise, powerlines must be shut down, relocated, or specially insulated by the utility.
i) ropes or barricades are positioned to prevent entry into hazardous areas around and
especially behind the crane
j) public access to the lift area is prohibited and barricades are available. Where the crane is
to be set up on a city street or public road, site supervision must ensure that it is possible
to use the required outrigger extension. This may require obtaining approval to shut off
one or more lanes of traffic.
5. supervising all work involving the crane.
6. determining the correct load weight and radius, and informing the operator. (Site supervision
should know the maximum radius, load weight and lift height of each lift before ordering the
crane). 7. ensuring that the rigging crew is experienced and competent. They must be capable of
establishing weights; judging distances, heights and clearances; selecting tackle and lifting
gear suitable for the loads; and rigging the load safely and securely.
8. supervising the rigging crew.
9. ensuring that the load is properly rigged.
10. ensuring that the signalpersons are competent and capable of directing the crane and load to
ensure the safety and efficiency of the operation. Knowing the international hand signals is a
must.
11. designating signalpersons and ensuring that the operator knows who they are.
12. ensuring the safety of the rigging crew and all other personnel affected by the rigging
operation.
13. keeping the public and all non-essential personnel clear of the crane and load during
operation.
14. controlling the movements of all personnel within the area affected by the lift.
15. ensuring that all required safety precautions are taken when the lift is in the vicinity of
powerlines.
16. ensuring that all personnel involved in the operation understand their jobs and
responsibilities.
17. ensuring that an emergency response plan is in place and is communicated to all relevant
personnel.
