Dear Kalairaja-Vairavaraj,
You asked very technical question on the forum of legal or semi legal fraternity here.
As you know the lifting generally takes place at construction sites, shipyards, factories and other
industrial situations such as offloading with a forklift truck, containers at a warehouse or at a
commercial area. This subject falls under workplace safety, and in India there are few guidelines available, as far as labour laws are concerned, under Factory Act, Mine Act BOCW Act. Those guidelines are totally inadequate.
You may refer to Indian Standard BIS: 1992 in respect to cranes, lifting chains, chain pulley blocks etc. Lifting plan also has set international standards with guidelines under it by various councils.
You may check with manufacturer or may refer manual for handling operations of the respective machines.
