Is there any standard practice for the lifting of cable drums using crane? What all precautions shall be taken?
Thanks

They can be lifted using a set of 2 legged chain brothers (2 legged chains)and a scaffold pole or similar passing through the drum. However, this isn't suitable for heavier drums, as the scaffold pole can fail.
Also, be aware that the cable must be tied off to prevent it uncoiling when lifted.
There are proprietary cable drum lifting frames available.

Hi Santhosh
Having looked at this and your other posting about confined spaces; I have to ask just which national area you're working in?
The answer will help us to focus a little better on providing relevant answers.

BS7121 is the BS for crane lifts. Note that the work must be planned by an "appointed person" - normally a 5 day course (see ainscough training services). The lift should be slung by a trained slinger/signaller. The lift plan (by the AP) will detail all the lifting tackle needed. A scaffold pole should NOT be used as it is not certified.

As part of my project work, I visited a construction site in North India where I found lifting of cable drums using crane, with web slings on a solid stainless steel rod passing through the drum. At the end of the lift I could see the rod is bent. I don't know as to whether the rod should be considered as part of the lifting gear, however it is their answer that the rod is locally made that astonished me. The capacity of the rod, weight of the drum etc. were unknown to the riggers. Now is it allowed to use chains/slings (after taking necessary care to protect edges) to pass through the cable drum for lifting purposes? And if solid rods are allowed, what standards/safety factors shall be considered. How can one ensure that the rod is sufficient for so and so load? Also I observed cable drums being rolled on to the forks of the forklift truck and is being transported to the site. This is the basis of my question. Please advice me about the standard practices on these in the industry.

All loads must be slung by a trained/ ticketed Banksman who is familiar with the correct method of lifting/ slinging loads and the particular loads to be lifted.
A major risk factor I could forsee is that many of these reels of cable don't have the weight indicated on the reel, however a catalogue held by most Electrical Contractors onsite will give you an indication of the weight per meter. It would be good practice where a Banksman is not sure of the weight of an item that they consult the appropriate contractor who will be familiar with the material.
Whatever equipment is used must be certified and rated for the weight to be lifted, this includes slings, chains, bars, lifting eyes etc. One method I have seen was a set of slings passed through the cable reel with the load 'choked' to prevent it moving during the lifting operation, however I would always rely on the experiance and skills of the trained Banksman.
