Governing design standards for material handling equipment in paper mill 2

[nhtr86]

I was asked a question about a hydraulically actuated arm in a paper mill that handles stock. What design standard would apply to this situation? I typically work in structural where the design of a steel component would commonly be governed by the AISC code or the AASHTO bridge code. I am looking for the document that provides required factors of safety, stress limits, etc. I plan to ask the owner for their requirements and specifications when I get a chance but wanted to get more educated before then.
Thank You

In my opinion, you have left the AISC universe and moved over to the realm of mechanical engineers --- machine design !!!

There is no one single design standard, like you have for steel frame design

See if you can purchase a used Shigley's text and review it .... a good place to start IMHO !!!

This well known and well used text will provide fundamental design concepts, methods and common factors of safety

Starting points include the ASME B30 standards

and the Material Handling Institute Standards

You might also need to understand the related IEC and ISO standards depending on where the equipment comes from.

As MJCronin indicates Shigley can be part of the details of design. I have used it myself.

Unlike the design of buildings, bridges, aircraft, and other structures I am not aware of any governmental code requirements in the design of common industrial equipment. Just remember this - if it fails and someone is hurt can you convince OSHA and/or a jury that you used commonly accepted standards of practice? If your client has some past projects they consider as worthy examples use them.

Consider all possible modes of failure, including misuse and poor maintenance, and try to consider them in your design.

This is where you encounter real world engineering.

In general, you are expected to follow those standards a structural engineer encounters daily - ASCE7, ACI, AISC, ASTM. In addition, you may need to get hands on design of storage tanks (AWWA), cranes (CMAA), and local building code, if permit is required. Also, the owner might specify standards for particular concerns. For large scale project, we usually arrange field visit, for designer to familiar with the equipment, the operation and maintenance needs. I remember ASCE has a publication for the design of industry buildings, which contains quite useful information for the beginners, or seasoned but unfamiliar with industrial practices. Finally, as pointed out by Jboggs, always be aware of OSHA requirement.

The more important question you should be asking is - should I be doing this? Not knowing common design standards (or suggesting they're essentially a how-to) pretty clearly shows when someone has no experience in a given niche and does not know the many pitfalls not covered by any design standard. Attempting to work in that niche unsupervised therefore is unethical at best. If you do this work and SHTF you have no recourse, you're guilty.
