Material Flow and Conveyor Systems, Inc. is proud to debut a new look to its website. While the look of the website has changed, Material Flow still offers top-of-the-line conveyors, pallet jacks, shelving and more from some of the best manufacturers in the material handling industry (including Genie® Industries, Stromberg, Vestil Manufacturing and more) at great prices!
First and foremost, it is not a rack with just oversize footplates. That does not make a seismic rack.
The following are most of the basics for determining a seismic rack job:
1. Floor thickness & reinforcement.
2. Soil compaction underneath slab.
3. Seismic zone the building is in.
4. Code requirements of the city: UBC or IBC and which version most cities are now IBC.
5. Rack layout and design
6. Number of beam levels and the spacing of those levels. The further the levels are apart the more that downrates the capacity of the frame.
7. Weight of the loaded pallets (Average Weight).
8. PSI and gauge of the rack to be used with column size.
9. Bolted structural, tubular or snap together roll formed.
10. An engineer licensed in the state the job is to be installed, once the engineer does the calcs and drawings, if everything checks out, the engineer stamps the calcs and drawings.
11. Brand has nothing to do with seismic calculations. Seismic rated rack is based on facts and conditions. Many salespeople and customers have little idea about the seismic rated conditions.
12. There are a few cities that have conditions beyond seismic.
As a side note, other considerations are OSHA, ADA and of course the local fire department.
These are the things it takes to have a seismic rated and approved rack job. Whoever gets the permit has to have all this information and sometimes even a little more.
1. Don’t turn it over to an architect until you have designed your storage, conveyor material handling layout. If you do, you are likely to get a cookie cutter approach, i.e. 12′ aisles for lift trucks and columns on standard centers which leads to problems.
2. You can’t determine the size of a facility until you know growth rate, new products being considered, new fields they might enter into and how many people they may hire. These are just a few of the things that need to be considered.
3. By doing number one and two you have taken an important first step, you are now involved with the planning process and are on the way to participating in your own success.
4. All of the above should be done before even picking a site or an architect.
5. Once you have completed your design and it may take from one to two years to complete this phase. It’s real simple, if you don’t put in the time during design then you will not get the results.
6. Are you looking to be unique or another “me too” facility?
7. Now you are ready to get an architect, engineer, general contractor. Some general contractors also have architects and or engineers on staff.
8. Check with the building department for land use requirements, height restrictions and other requirements. The more you know the better off you will be.
Solectron is a contract circuit board manufacturer located in Milpitas, California. The company depends on efficiency and cost effectiveness to successfully manufacture quality products. When Solectron was looking for a new cart to handle storage and transportation needs for circuit boards, they turned to Metro for a custom solution. Although lowering costs was an issue, they also wanted an innovative solution.
