    Safety Factor

    Thanks for all the info. Yes, in the US. I found a reference of IBC 2006, ASCE 7-05, and 9th Edition ASD AISC Steel Construction Manual that a co-worker found on a mezzanine vendor website. I'm guessing that this is correct? A little more info. The equipment is already in house and there is...

    Safety Factor

    Can anyone tell me if there is a recommended safety factor for design of mezzanines? It is a mezzanine for equipment, so people are not normally on top, but people will be working underneath. We purchased the mezzanine as a part of a whole package of equipment. We are concerned with the...

    AB Viewer

    Thanks for all the info. I have RSLadder. However, in looking at the release notes, you have to have RSView which I don't have and if you use third party software with it, it says that you have to purchase a license. So why does it come bundled with RSLinx when you can't use RSLadder with it...

    AB Viewer

    Thanks for offering to print it, but the program is fairly large. I think that I need the RSLogix500 starter edition. Thanks for the help. I think that the dealer and I were getting our wires crossed. I was kind of hoping for a free or almost free viewer only, but I guess I'll see if I can...

    AB Viewer

    I don't normally work with PLC's. So, I have a question about Allen Bradley. I want to view a program and only view, nothing else. But I think that someone told me that you have to RSView or RSLogix to view programs. Does anybody have a free or low cost program just for viewing AB programs?

    Software preferences/experiences

    I would say fairly extensive compared to most other equipment that we use. Defintely more than just a single screen for inputs. We run a series of 6 tests in 2 stations. Tests require switching of HV electrical switches, input and recording of data by serial number, calculating of data to...

    Software preferences/experiences

    Currently, we use Wonderware to operate a test station that uses PLC's to perform switching and feeds back data from the test equipment. However, we may be purchasing new equipment and/or upgrading old equipment, so we are considering switching software platforms. I have been told that Labview...

    HK, HT, or HU material in annealing application

    No, we really haven't done failure analysis of the grid plates. Since we are a manufacturing facility, we really don't have the equipment to do that sort of thing. Yes, air only.

    HK, HT, or HU material in annealing application

    The grids are round and are made up of 3 sections, with 2 sections being half circles. Basically, divided in 3 by 2 parallel lines. The sections are bolted and welded together. The half circle sections end up pulling away from the center section, distorting more at the thinnest cross...

    HK, HT, or HU material in annealing application

    We are looking at changing the material of grid plates that we use in an annealing oven. The max temp is around 1550 deg F. We currently use HT material. One person has recommended HU or HX (increased Nickel content) to increase ductility while another has recommended HK (increased Chrome...

    Handheld rectangular wire bender

    I guess that this is a low tech question, but I am looking for a handheld rectangular wire bender for magnet wire. The largest size would be around 0.18" x 0.60" rectangular wire. I have looked around and have not been able to find exactly what we need. Someone mentioned that a power...

    Soldering AL to CU

    Does anyone know of a good solder for joining aluminum to copper? We are currently using Johnson Mfg #435 with AL300 core. Would like to find a backup supplier with the same tpye of flux core solder wire. Thanks

    304L vs 316 SS in high heat environment

    I've seen some discussion on 304L vs 316 SS in a high heat environment, but would like some clarification. Or maybe material recomendation. We use tooling that we use as a form to anneal steel into a particular shape. Temperatures reach around 1550 degrees F. Because we are annealing...

    caster wheel types

    I don't know if this is too simple of a question. I'm new in manufacturing engineering and need to order some casters for some carts. They will be loaded to around 2000 pounds and the floor is painted concrete so I was looking for something with floor protection. We were also hoping to use...
