Electric Hoists

Largely depends on what your lifting and how fast you need to do this. It also is dependent on ambient temperature etc; But for the most part, it falls to personal preference.

Dear Mr. fixitorelse,

Kindly inform how the ambient temperature is involved. I am eager to know on this point.

My suggestion, posted will indicate EOT CRANE, to be installed - for which my inferences are to be confirmed, by Mr.Mohammad Akram Khan.

thanks,

Hot metal handling you may not want to have a chain, cables are far more forgiving.

Dear Mr. MohamadAkram Khan,

Some more details are required. What I understand from your post - is

1.That each pump has one hoist, only lifting/lowering - single motion up or down.

2. Do you intend to install EOT Crane, for replacing the existing hoists. If so, what is the Span for travel and traverse.

If my inference is correct, which you have to confirm, pl. specify that (a) Span for Travel, Traverse, and Lift as you mentioned. (b) Pl. Specify the Motor should be Crane Duty Motor. (c) Pl. specify the Pulley/Rope Ratio should NOT be less than 20, so that the life of Rope is not shortened. (d) The deflection should NOT exceed L/900 where L is the Span in the Long Travel. Some Countries adopt L/800 as the Ratio for DEFLECTION. (e) Ask for Wire Rope with HEMP CORE.

Thank you for your response.

Let me please clarify:

1. The gantry granes are existing and we are only replacing the hoists. The existing hoists are chain blocks and these will be replaced by electrically-operated hoists.

2. The longitudinal and transferse travel will remain the same i.e. manually-operated. Only one hoist is to be installed for 3 to 4 pumps.

Kind regards

I would contact a couple of hoist manufacturers for recommendations.

Some things they might need to know:

Budget?

Any relevant safety code (i.e., OSHA) compliance required? (The manufacturers may have this information, but you should verify it yourself.)

Are the hoists used every day, or only for annual/infrequent maintenance & repair?

Thanks for your comments.

The hoists are for infrequent miantenance purpose only.

Yes, budget is also an important factor. For a given SWL, which hoist (chain or wire rope) require less capital investment ?

I haven't done any price comparisons. Do some basic research on what products are available and in your price range, then call the manufacturers for recommendations based on your specific requirements.

In my opinion, it's preferable to contact the manufacturers directly, rather than a distributor. The distributors are more likely to recommend products that can make them the most money.

Thank you for your comment.

I fully agree with you about dealers !

Also keep in mind the environment. Wire rope tends to corrode from the inside out where moisture becomes trapped. This makes it difficult to detect a cable no longer suitable for service. This is one reason why we don't use wire rope hoists. Chain type is easier to inspect.

Thanks for your comment. Moisture is no doubt an important factor to be considered
