This video is a short few minutes, and features vertical reciprocating conveyors implemented by Cisco-Eagle at defense contractor Electric Boat, Inc. The company manufactures submarines at its Groton, CT facility.
The Material Handling Industry of America recently announced that the RMI (Rack Manufacturers Institute) has certified several manufacturers of wire rack decking “R-Mark” compliant, meaning that these companies have conformed to the Institute’s testing and utilization standards. The industry developed the latest and most comprehensive consensus documents ANSI MH16.1 – 2008 – Specification for the Design, Testing and Utilization of Industrial Steel Storage Racks and MH26.2 – 2007 – Specification for the Design, Testing and Utilization of Welded Wire Rack Decking. Members of RMI voluntarily choose to conform to ANSI MH16.1 – 2008 and MH26.2 – 2007 and any successor document(s).
Designing your conveyors and workstations to work together gives you significant safety and efficiency advantages. Using conveyors is a good way to reduce the risks of musculoskeletal injury in tasks or procedures that involve manual handling because conveyors reduce the need for repetitive lifting and carrying, but implementing conveyor into workstations requires some basic understanding of how to prevent stress. As a bonus, well-implemented conveyor workstations also boost productivity.
Transferring onto belt conveyors isn’t recommended due to box tracking issues. When you use belt conveyor, boxes will probably drag the belt as they enter, which will push the belt toward the far side. (Above: boxes may cause tracking problems)
If you can’t avoid using belt conveyors to transfer, the transferring conveyor should be positioned so that it overhangs the belt conveyor, as shown above. Boxes will drop onto the conveyor. If your load cannot be dropped, another solution may be necessary. For assistance with these kinds of transfers, contact us.
Cisco-Eagle has created an informative article you should check out if you are thinking of installing a mezzanine in your facility. When implementing an Industrial Equipment Platform (mezzanine) be sure that you are not putting too much stress or weight on the floor of the building. Too much weight will cause the floor to crack – or worse. This article tells you how to calculate the correct load capacity and column spacing for any new structural mezzanine project. Floor capacity depends on the thickness of the concrete, but that’s not the end of the story. It also matters how much the soil underneath the slab will compress.
At this time of the year, many companies find the need to maintain open access to dock doors and warehouses without letting heat and other environmental controls escape into the cold. The obvious solution has been to install vinyl strip doors, which allow easy access to foot and lift truck traffic while they also keep climate-controlled air in – and cold air out.
We’ve created a guide to specifying vinyl strip doors to help you understand what types of strip materials to use, how much is needed to cover a particular opening, and which mounting system might work best for you.
Since overloading is a common source of pallet rack collapses, (in fact misapplication, including capacity issues, is the top cause) it’s important to understand how much weight your rack – not just your beams – can bear.
For a piece of storage equipment that is relatively simple, ensuring that the rack can hold what you want it to hold is sometimes complex – particularly on very heavy loads, or large but not so heavy loads. This article focuses on upright frame capacities. Beam capacities are pretty simple – they’re listed per pair of beams by most rack sellers, and you just adhere to them with your pallet loads. But frame capacity is not as straightforward as a beam capacity…
When you are running an operation with lots of racking, it isn’t uncommon to have to replace an occasional upright or beam, or to add new bays onto an existing row. Sometimes you cannot avoid it, as the rack was purchased years ago, by someone else, from a source you can’t even locate. It might be that you bought used rack and need to fill some gaps in, or it may be perfectly good, 15-year old rack that just needs some expansion or damaged components replaced.
This is done all the time, and although it isn’t an optimum situation for rack stability and safety, you can minimize the issues by following the following guidelines:
Just some tips we’ve picked up along the way when it comes to keeping pallet racks safe:
The majority of pallet rack structural failures result from just three sources – know them, and most of the rest takes care of itself. Those include (1) impacts from a lift truck collision; (2) Misuse and overloading (3) Lack of comprehension that racks can be dangerous, and the lack of a safety oriented mindset. Really, the focus is on #3 gets you to #1 and #2. Operations with a safety mindset will also understand that impacts are deadly, and they know how to safely load their racks.
Know how your rack will be used when you spec it. “The two main rack safety points are the proper initial design of the structure so it doesn’t collapse, and proper training of personnel to ensure a clear understanding of the structure’s operational characteristics,” said Rack Manufacturer’s Institute (RMI) President John Nosfinger in a 2008 Modern Materials Handling article. If you inherited the pallet rack in your operation from someone else, find out the details of the rack system and its design. File that so that anyone can access it, and enforce your capacity ratings so that your racks will not be overloaded or mis-loaded.
