Pallet rack anchoring requirements

Pallet rack anchoring requirements:

Selective Pallet Rack Installation

  • Layout the floor as described.
  • Stand the first two uprights in a row and install all beams. Rough plumb the first bay so that the row does not lean too much as the install proceeds. Typically, if only the first level of beams is tightened, it will hold the starter bay plumb. Be sure to loosen these beams when the row is complete and ready to plumb in the down aisle direction.
  • Anchor these uprights at the appropriate points on the grid, but only set the anchors halfway into the holes and do not tighten.
  • Proceed with the erection of the balance of the row. Install the beams, but leave the connections loose.
  • It is recommended that the uprights be anchored as the erection proceeds, but only by setting the anchors halfway into the holes. This ensures that when the rack is cross aisle plumbed, there is enough length left in the anchor bolts to add shims if necessary.
  • Once the row is completed, make sure it is anchored, but only set the anchor s half way down.

Storage rack design guidelines

  • Make sure the uprights are positioned accurately to the layout grid.
  • Shim the rack cross aisle. Place a plumb bob on each upright and shim either the front or rear base plate to straighten the frame. See shimming guidelines & diagram page 9.
  • Once the row is anchored and shimmed cross aisle, proceed with tightening the anchor bolts.
  • Proceed with the installation of pallet supports and back ties. This can be done at the same time as installing individual bays, but leave the bolts loose.
  • With the row anchored, detailed, and plumbed cross aisle, begin plumbing the row in the down aisle direction.
  • Attach a cable to the top beam elevation of the first upright on the front or aisle side post, in the row of sufficient length to reach 5 to 6 uprights back at the base.
  • Hang a plumb bob, use a transit or a bazooka bob, to determine in which direction the row of needs to be pulled.

Industrial storage Rack design

Check both the front and rear posts of the upright. It is possible that the front post of the upright may need to go in one direction and the rear post in the other down aisle direction.

If this occurs, add additional cables to the rear post as well, to pull the row square.

  • Attach a come-a-long to the end of the cable to aid in pulling the row.
  • Check the first and last frame in the row and if it is within tolerance, tighten all bolts in the beams, pallet supports and back-to-back ties with the cables in place. If the last upright in the row is out of tolerance, attach a second cable at the rear 5 bays and pull the row in the opposite direction, to eliminate any growth that may have occurred due to the slop in the beam and upright holes and then tighten all bolts in the row.
  • If the row of rack is particularly long, this process should take place in 25 bay sections.
  • The row is complete once all bolted connections are tight.

Each row of rack should be plumbed in this fashion. If you choose to plumb a back-to-back row down aisle with the back ties installed, you must be sure that all four upright posts are in the line with each other in the cross aisle direction. Both rows must be aligned with each other.

Do not use a 4-foot level to plumb any rack over 10 feet tall. This method is very inaccurate and should not be used.

How to secure pallet racking to the floor?

Pallet storage and pallet rack installation jobs require an experienced crew with the proper tools and equipment. Many people involved in pallet racking jobs don’t really know how to install a pallet rack. 

Pallet Rack Inspection checklist

Few warehouse operators have aggressive in-house rack inspection programs in place. Forklift accidents, collisions, dropped or misplaced loads, and other incidents that result in rack damage may or may not get promptly reported.

Pallet rack anchoring standards

Many projects require special anchor details that will be shown on the erection drawings.

The installer must follow these anchoring details. In the absence of such details, for standard pallet racks, it is recommended that one anchor bolt be used per column and that the anchor be ½ ”in diameter and provide 2-1 / 2” of nominal embedment in the floor.

Nominal embedment is defined as the amount of anchor that is below the floor surface before tightening.

If the base plate is a larger base plate with four holes, at least two anchors per column should be used at opposite corners of the base plates whenever possible.

Pallet rack assembly instructions

When installing anchor bolts, the builder should refer to the anchor bolt manufacturer’s anchor bolt instructions for torque values ​​for the anchors.

The anchor bolt torque is less because overtightening the anchor bolt will fail the clamping device and possibly pull the anchor off the floor.

Although we recommend always anchoring, some codes suggest that anchors for short stable racks (8 feet in height or less) that are manually loaded and unloaded in low seismic areas can be omitted.

Installation of the remaining bays

Remaining bays can be installed making sure the rows are straight above the chalk line and subsequent frames remain plumb (within 1/4 ”for every 10 feet of height) in both the aisle and aisle directions. .

The rest of the row of shelves can be set up before anchoring. All footrests in the remaining bays should be anchored like the boot bays (see boot bay installation).

Never attempt to plumb a screen after fasteners have been tightened or use excessive force to plumb a screen.

This could bend or damage the frame members. Periodically check plumb bob as rack installation progresses.

It can be very difficult to connect multiple rack bays that have been installed outside of lead.

Can you walk under pallet racking?

I have come across this situation many times before and have never had a problem with it.

Stock pickers are working under the shelves all the time to retrieve items from the back of the bays.

A shelving collapse will be catastrophic regardless of where a staff member is in the warehouse.

By providing mesh on the back and sides, it seems reasonable to add security.

There should be no unsecured loads stored on a high-rise pallet and a racking inspection and damage reporting scheme should ensure that the racks are stable.

Pallet Racks Safety Tips

Pallet rack beam capacities are pretty simple. They’re rated per pair for evenly distributed, properly-positioned loads. But upright capacities are more complex because their capacity is calculated on vertical beam spacing.

The largest vertical gap dictates the capacity, so be aware of tall loads, which can stress a rack more than a squat, heavy load because extra beams act as lateral support. Get these factors right, and your rack will be safe and stable.

Working under pallet racking

Pallet racks are designed to easily hold pallets loaded to maximum capacity and could theoretically support more weight.

After all, the steel structure is what supports many skyscrapers.

The steel frame that makes up most warehouse racks is generally built to handle one of six ISO standard pallet sizes and whatever cargo those pallets can normally carry.

The typical figure is approximately 2,000 pounds of static load for the typical North American Grocery Manufacturers Association (GMA) specification pallet, and the racks will be constructed with a centerline beam that can support at least 2,000 pounds. on each side of the beam facing the aisles.

Exact loads may vary depending on pallet rack configuration and the types of pallets used.

A Guide to Storing Difficult, Bulky and Long Loads

Storing rolls and reels

Rolls, reels and other spooling loads can be stored on pallet racks. To accomplish this, special reel pockets are placed on the upright and then fitted with a horizontal bar.

Rolled items like film, wiring, cables or paper are placed on the bar, and can be dispensed. The capacities for these racks must be understood, since the loads are dynamic. Reel pockets have capacities (calculated per pair) that must be taken into account.

Long item storage

Many long items can be better stored on cantilever than pallet racks, but there are applications where pallet rack fits better in the storage strategy of your facility.

We’ve done projects, for instance, where long rolls of film or fabric can’t be stored on cantilever arms because the arm would dent fragile materials and full support is needed.

You may already have pallet racks and want to adapt them to store longer loads. Pallet racks can be adapted with relative ease for these applications.

What can you do to reduce risks?

Load the rack with adequate clearances

Load your racks with acceptable tolerances above and to the sides of each pallet and the frames. You should have 10” head clearance between the top of load and the bottom of the beam above it.

Add technology to help drivers see

Technology is only an enhancement to training. It can’t prevent accidents on its own, but can help drivers see and understand the situation better.

Options include cameras that let drivers see the load and beam, laser tine guides, tine leveling alarms and more.

Install product/pallet fall protection systems

If forklift drivers bump a pallet and knock it, or a palletized carton or other loads-off, then protective systems like safety netting, straps, back beams/bars, or wire panels can stop the fall and help prevent damage and injuries.

Pallet Racking Inspection Requirements

Do you know pallet racking inspection requirements?

  • Are racking inspections a legal requirement?
  • When do warehouse storage racks need an inspection?
  • When was the last time you had your warehouse and storage racks independently inspected for integrity and safety?
  • Would any of your supervisors or line managers respond, “What do I mean “independent” inspections?

Or — of greater concern — would they scratch their heads and ask “What do you mean rack inspection?”

Few warehouse operators have aggressive in-house rack inspection programs in place. Forklift accidents, collisions, dropped or misplaced loads, and other incidents that result in rack damage may or may not get promptly reported.

But even when a forklift hitting the front end corner of a rack gets reported, a typical management response never goes beyond “let’s go take a look,” as if a quick visual inspection alone will confirm that load limits and structural integrity of the rack have not been affected by the accident.

It’s as if, while other hazards “stand out” to otherwise reasonable and prudent supervisors, there often is an absolute lapse in concern for 100,000 pounds of rack and product collapsing in a pile across the tight confines of a busy warehouse.

Why do i need a racking inspection for pallet racking?

Racking is often installed based on its versatility, reliability, and capability to support large loads – making it easy to fall into the trap of thinking that it requires minimal maintenance.

While racking should certainly last for a long time and be resistant to damage, it’s also important to keep assessing its condition so that you know when something is amiss.

While you shouldn’t leave all of your safety oversight to racking inspectors, regular inspections are an important element of health & safety compliance, as well as a means to protect people in the workplace.

Industrial storage racks manufacturers

Manufacturing and warehousing racking environments create severity exposures that are typically overlooked or not considered by material handlers and employees working around storage racking systems.

With forklifts maneuvering back and forth and constantly lifting and lowering heavy loads co-workers don’t realize that pallets do fail and quite often operators make judgment errors that result in falling materials.

When that happens, it is conceivable that racks will fall over crushing workers and materials do fall from forklift forks striking and seriously injuring workers.

OSHA storage rack anchor requirements

To avoid these pitfalls, racking systems should be inspected at least monthly to make sure the racks are in compliance with OSHA standards and they have been safely and properly installed, loaded, and without damage.

While OSHA does not have a standard racking guideline, they do site the general clause which states employers shall provide a workplace that is free from recognized hazards.

Whether your racks are damaged or installed improperly they can create a workplace hazard that can be found in violation of the regulation and result in a fine/citation.

Fines typically result from damaged or smashed racking, non-engineered repairs or modifications, unposted weight capacities, and racks not being anchored to the floor.

Storage rack solutions

  • What does it mean if my rack is ‘out-of-plumb’?
  • How about ‘out-of-straight’?
  • ‘Out-of-plumb’ means your rack is not exactly vertical – it’s leaning forwards, backward, to one side, or the weight of its contents is causing it to buckle in or out.
  • ‘Out-of-straight’ means your rack is not level from side to side – one side is higher than the other. If you place a marble on an out-of-straight shelf, it’ll roll to one side. A rack that is out-of-plumb is frequently also out-of-straight.

The out-of-plumb and out-of-straight limits for a loaded rack are the same: 0.5 inches per 10 feet of height. If your rack exceeds these limits, the rack should be safely unloaded and re-plumbed.

I have a sprinkler system installed in my warehouse. Will racking interfere with my fire protection?

OSHA mandates a minimum vertical clearance of 18 inches be maintained between sprinklers and any material below. You must also ensure that sprinkler spacing provides a maximum area of protection per sprinkler and that interference of the water discharge pattern due to structural components and building contents is minimized.

If you have already installed a sprinkler system, you’ll need to add your racks in such a manner that they don’t block the sprinklers. Other fire hazards may come into being with a new racking installation, including new fire exit strategies, reduced exit visibility, and increased proximity of racked material to lights and heating elements on the ceiling. Be sure to retrain employees as needed, especially if you are installing multiple new racks.
