Pallet racks are a necessity in most warehouses for storing large quantities of inventory. But, like most people, you want to store your inventory the safest way possible without going overboard on expense. No matter what kind of rack you go with, they must be secured to the concrete floor for stability and security. Here are the steps to properly anchoring your pallet racks to the floor.
1. Choose the location. Finding the perfect place to install and anchor your pallet racks is key to having a successfully run warehouse. You'll need to take into consideration where shipping and receiving is as well as the staging area, the location of the manager's office, how easily items will be accessed with your forklift, and any existing obstructions like overhead beams and columns. Narrowing down these details in advance can prevent the need to move things around down the road. Before anchoring the racks, make sure the floor is level or that the racks are level in their location. If needed, move the racks slightly until they give a level reading. Once you've got the location determined, it's time to choose the right type of anchor.
2. Select the right anchor type. Most people choose between a wedge anchor or a strike anchor. Both are ideal for use in solid concrete and come in varying lengths, but the wedge anchors come in different diameters to suit individual needs. If you go with a wedge anchor, you'll select the diameter that goes with the hole size in the bottom plate of the rack.
Concrete strike anchors are impact-expansion anchors, which means the anchor legs open once placed. These anchor types improve productivity since they don't take long to install. When deciding which type of anchor to use, it's best to go with the pallet rack manufacturer's instructions, blending that in with your own personal experience and preference.
3. Select the right anchor size. For both the wedge anchors and the strike anchors, you'll need to figure out the thickness of the material that will be fastened as well as the nut and washer and add those values to the minimum embedment. That number will determine what length anchor you need. If the racks have a supported edge, you should space the wedges 10 anchor diameters apart, and with no supported edge, there should be at least 5 anchor diameters between each one.
The hole depth is another factor for the wedge anchors, and to determine that, you simply subtract the thickness of the material being fastened from the length of the wedge anchor.
4. Install the anchors. To put in the wedge anchors, you'll need a hammer drill with a carbide-tipped masonry bit.
Select a drill bit that's the same size as the diameter of the wedge anchor. Going through the bottom plate and using it as a template, carefully drill a hole, then clear the holes using compressed air or a wire brush and vacuum.
Put the washer in place and turn the nut several times. By not completely threading the nut, you're reducing the risk of damaging the thread on the anchor itself.
Insert the wedge anchors and hammer them in place, all the way down to the required depth. And last, tighten the nuts using a torque wrench.
To place the strike anchors, you'll start the same way by drilling a hole the same size as the diameter of the anchor. But before placing the strike, you need to put the washer in place and thread the nut on the strike anchor. Place the strike anchor through the hole on the pallet rack and use a hammer to set the pin until it's flush with the top of the anchor.
