Dear Mr. Pon
TPI is not always practically possible... Can you name few Indian companies they are doing this TPI for every boom modification they are doing?
In India third party inspection & certification is just so easy... If you have money in your pocket by sitting in your home, you will get that certificate...
The main thing is that we have to ensure the stability of the crane for lifting after certain configuration change... This can be check internally by a group of experts... Experts may include the Crane Engineer, Supervisor & the Rigger Crew... Go for a load test with 1.5Times the rated capacity... Lift the load and raise the same about 1meter and hold it for five to ten minutes... If it's giving satisfactory result we can go for further lifting with the crane... no need of TPI...
Even in some TPI the Competent person itself not ready for load test... just have a look and noting all the required parameters of the crane to make the certificate... So trusting upon a TPI in today's Indian Scenario for a Safe Rigging is absolutely not advisable... This is my belief...
Awaiting comments friends...
