Dear Kalairaja-Vairavaraj,
You asked a very technical question on the forum of legal or semi-legal fraternity here.
As you know, 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 a few guidelines available as far as labor laws are concerned under the Factory Act, Mine Act, and BOCW Act. Those guidelines are totally inadequate.
You may refer to the Indian Standard BIS: 1992 in respect to cranes, lifting chains, chain pulley blocks, etc. A lifting plan also has set international standards with guidelines under it by various councils.
You may check with the manufacturer or refer to the manual for the handling operations of the respective machines.
