Hoist Design

[euthro]

I am about to start a project management role for a large scaffolding & hoisting firm. The field work is a prelude to starting up in the office and starting design of hoists. I am looking for good guidance material for the design of hoists, so I am somewhat up to speed, or at the very least have the basic concepts before I start in the office.

Any help is greatly appreciated.

Whare are you located?
In the US, getting VERY familiar with the various OSHA regulations would be helpful. Or your state OSHA, if there is one.
Also getting familiar with the ASME or other standards dealing with the equipment in question.

Thanks for your response, I have been working as a project manager so I am up to date with OSHA and all relevant health and safety standards.ASME standards was the first thing I looked up but what I am really looking for is real life design of hoists and the key factors which can cause problems with design. The first document that came to mind to revise is wind codes.

I am based in NY but did my studies in Europe so though I have worked to American Standards its still new to me hence I am looking for links to good material to learn basic concepts and key features.

Try to find "Tips for Avoiding Crane Runway Problems" by David Ricker, AISC Engineering Journal, 4th Quarter, 1982.

Euthro:
Are you talking about 20 story worker and material hoists, or something else? We can’t see it from here. Why don’t you gather as much sales and engineering literature as you can on your own company’s and your competitor’s equipment, and study it for industry std. details and means and methods. What codes or industry stds. does that industry work to on these products. Then, just good clean engineering design and detailing for all the possible loads and conditions, with attention to good clean assembly details, fool proof details, etc. It should not look fully assembled and usable if important parts are missing. It should be stable during assembly. Keep in mind that your 2000lbs. load limit sign isn’t always followed. Laborers tend to fill up the space or volume, wether it’s feathers or bags of cement. With the design of these specialized products, it is really helpful if you can find a mentor, company project and product history files, etc. Certainly, enlist the help and guidance of knowledgeable people within you company, there should be no shame in that. I would guess this hoist design is not unlike elevator design. Some knowledge of lifting, rigging, cranes, derricks, and the like might be helpful; and textbooks on Strength of Materials, Theory of Elasticity, Steel and Concrete Design, Machine Design, Mechanical Product Design, Fabricating and Welding would seem to be in order.

Good Luck.

BTH-1 Design of below the hook lifting devices might come in useful.

This should give you some ideas on what a serious hoist looks like..... typically 20-30 tonne loads at 2000-4000 feet per minute.

Not sure what but if you asking for good "material for the design of hoists" as assume CAD designs etc. Try CM works library.

Hope that helps
