Seeing Around Corners: The Danger Spots in Warehouses & Factories

August 28, 2012

pallet rack row end and forklift traffic

In an industrial environment, intersections can be dangerous. With fast-moving workers who are busy and probably distracted, and fast-moving forklifts that may have loads elevated that can obstruct the driver’s view, corners, ends of rack rows, and intersections can be the cause of many accidents. Whether it’s a worker walking and carrying a load, or a forklift on its way to the next pick, the chances of collisions, injuries, and damages are greater at intersections than most anywhere else. What are your options when it comes to making your intersections safer?

How to Store Stacks of Empty Pallets

May 4, 2012

pallet stacks

Most distribution and manufacturing operations deal with empty pallets. Sometimes, a lot of them.

Empty pallets take space you could use for something else as they clutter your receiving area. Sometimes they’re splintery, with nails protruding from the sides ready to bite a passerby. People re-use their pallets, holding onto them for a period of time until they’re used for an outbound shipment. But while they’re in your facility, they can eat space, potentially injure people, and generally cause trouble.

9 Ways to Reduce Product Damage in Your Warehouse

February 16, 2012

crushed box

In warehouse & manufacturing operations, things get broken. They break in a number of ways, and it’s expensive. You’ve probably seen product broken or damaged in amazing and improbable ways  if you’ve been in this business for any length of time. We had a client once buy a bunch of mismatched, used industrial shelving (not from us), only to see it collapse and dump thousands of tiny aircraft components on the floor. It had to be swept up and discarded since it was all mixed up and visually impossible to sort.

Those are extraordinary examples, but everyday inventory damage that cost “only” a few hundred or thousand dollars can savage your bottom line.

Options for Bar Stock, Tubing & Pipe Storage Racks

March 24, 2011

storing bar stock

Especially in heavy manufacturing, machine shops, petroleum or chemical operations, large bundles of pipe, tubing, bar stock or other long, heavy loads must be stored and picked during the day. Multiple ways are available to store these loads.  They can be picked by forklifts, by hand, by hoist or by crane. The choices you make will determine how you access the product (and how easily), how much space it takes and its safety. Here are the options:

Storing it on the floor

In some operations, this is the default method. Sometimes these loads are floor-stored between bollards and a wall, or other obstructions that prevent them from rolling or falling outside the defined storage area. This method is the baseline, and it’s not pretty.

  • Cost: Floor storage has no direct cost. There is not much if any equipment to purchase. Some installations require bollards or posts, or floor striping for organization.
  • Space Consumption: The floor is going to host exactly one bundle in a given area. It’s not going to stack well, and if it does, that’s a potentially dangerous stack.
  • Ease of access: Ever try to pick up a 12′ bar of steel from the floor, or even off a stack? Typically you can use a hoist, but not a forklift. Most of the time, floor loads are hand picked.
  • Safety: An unsecured bundle isn’t safe. But one that sits on the floor isn’t going to fall on anyone, although it might slide out onto legs or feet.

For any significant operation, this is going to slow you down, endanger people and cause inventory damage. It’s acceptable for a very low moving stock that is near to its processing machinery or otherwise in a niche somewhere that isn’t expected to grow.

Cantilever racks

Cantilever racks storing tube stockA good majority of these loads are stored on cantilever rack. Drive around any industrial district and you’ll see cantilever racks holding tube and pipe loads everywhere, and for good reason. It works, it’s relatively inexpensive and it’s durable.

  • Cost: Cantilever rack is cost-effective. It can range from a few hundred dollars to several thousand per rack, depending on the height, capacity, length, etc.
  • Space Consumption: Cantilever racks allow you to place stock (like steel, aluminum or iron) into racks and off the floor so you can utilize vertical space, but you’ll need space for forklift aisles. Cantilever can utilize more vertical space than anything else you can do, so you’ll be able to take advantage of building height with it. Column capacities get into the tens of thousands of pounds and arm capacities into the thousands. For a single aisle of storage, it is the best option. For multiple rows of storage, the aisles tend to reduce density.
  • Ease of access: Cantilever can be loaded or unloaded with forklifts or stackers or by hand (if the load is light enough). The static arm positions tend to make hoists or cranes unworkable, since the upper layers obstruct the lower ones.
  • Safety: If properly specified, cantilever racks can reliably hold heavy loads. Workers need to be cautious when handling any large, unwieldy, heavy item whether racked or not.

Stacking racks

Stacking racks are the most versatile option, but also have severe limitations.

Stacking rack with pipe and tube storage

  • Cost: These racks are inexpensive, but you have to buy multiple ones to accommodate greater lengths of stock or tubing.
  • Space Consumption: Stacking racks can provide a fairly dense product storage method. They can be stacked (depending on type) four to six layers high. They will require aisles for loaders or forklift access. They do not have the vertical utilization a cantilever system does.
  • Ease of access: You must unload the top layers to get at the load in the middle or on the bottom layers, no matter the method you’re using for loading or unloading. This results in what amounts to extra picks every time you access anything but the top layer. For a product that is all the same in a given rack, that’s not a problem – pick a layer off and go to the next. For mixed stock, it’s a disaster.
  • Safety: Stacking racks are stable if specified and stacked correctly. Don’t overfill them or add layers over what the specifications tell you.

11% of Forklifts are Involved in Accidents Annually. What Can You Do?

January 14, 2011

hurtling forklift

There isn’t much other way to say it: If you have a forklift, it is almost surely the most dangerous piece of equipment under your roof. If you have many forklifts, that danger us multiplied.

How dangerous? According to OSHA estimates, there are 61,800 minor injuries, 34,900 serious injuries and 85 forklift related deaths in the United States every year. Since there are almost 900,000 forklifts operating at any given point in the United States, this is something that every operation needs to consider when your forklifts start moving on a busy day. 11% of them stand a good chance of being in an accident or collision every single year. Those aren’t great odds, considering that a forklift in a given warehouse is heavy, moving, and in a noisy and often visually crowded environment.

Saving Space in Rack Storage Areas

December 3, 2010

Pallet rack storage is relatively inexpensive and extremely common. In many facilities, it also consumes the majority of square footage. When you can cut down on this space, significant gains can be made that allow you to use the square footage for other purposes. Here are some ideas for reducing your rack storage footprint while maintaining storage capacity.

How to Safely Store Gas Cylinders

October 26, 2010

One of the more dangerous items that you’ll find at virtually every facility is the humble gas cylinder. In warehouses or manufacturing operations, you’ll find LPG (liquefied petroleum gas) canisters that power gas forklifts. You’ll also find vertical cylinders for welders, cutting torches, or other equipment operations. Too often, you will find them standing against a wall or on the dock with no protection at all.

Horizontal Carousels: Why Top Drive is Better

January 6, 2010

top driven horizontal carousel

The age-old argument of top-versus bottom-driven horizontal carousels comes up all too frequently (at least among carousel people). You may think it doesn’t matter that much but in fact, it makes all the difference in the world. Supporting something from underneath makes sense. After all, trains, cars and most rolling objects are bottom-supported. Yet, the best designed horizontal carousels in the world are top-supported units that outperform bottom-supported units in both speed and efficiency. How can that be?
