Page 4: Push Back System Introduction
Push Back System Introduction: Push back rack systems are a high density storage solution. The advantage of a push back rack system is that all loads are stored and retrieved from the same aisle. This reduces the number of aisles needed in a facility, freeing up more space for storage. - Page 5 Basic Components There are three basic components to a push back rack system (See Fig. 1): 1. Rack Structure, consisting of upright frames and horizontal beams. 2. Push Back Rails, on which the carts ride 3. Carts, which support the pallet load and roll freely on the push back rails.
- Page 6 System Design The push back system installed in your facility was designed to handle pallets and loads of a particular size and weight. For example, if your push back cart was designed to use 40” wide by 48" deep pallets, do not use pallets that are longer or shorter than this size.
- Page 7 Pallet load weights, in a single push back lane, should not vary by more than 500 lbs. In other words, you should not store a 2,000 lb load in the same push back lane as a 1,000 lb load. Similarly, push back rack systems are not intended to be used for applications where the aisle-side pallet is “picked.”...

Page 8: Pre-System Use Inspections
Pre-System Use Inspection Steps: Pallet Before using a pallet in the push back system, fork truck operators need to examine the pallet style and pallet condi- tion. Defective or damaged pallets may not allow the push back system to operate correctly. Pallets should be GMA style pallets, with at least five (5) bottom boards running left-to-right. - Page 9 Pallet Load Pallet loads need to be securely banded or shrink-wrapped to the pallet before placing in the push back system. Having loads properly secured to the pallet will minimize the potential for shifting of your product when loading and unloading the system.
- Page 10 Push Back Lane Fork truck operators need to periodically examine push back lanes to ensure that they are free from debris (wood chips, slivers, etc.). In particular, push back rails must be free of debris in order for carts to work correctly. Debris left on push back rails may pre- vent carts from being pushed all the way back, returning all the way forward, or...

Page 11: Proper Loading Procedures
Proper Loading Procedures: When ready to place a pallet load into the push back system: Carefully pick up the pallet and slightly tilt the forks upward. Tilting the forks upward puts the pallet inline with the upwards slope of the push back system. See Fig. - Page 12 Position the first load no more than 3" above the top cart. Continue entering the lane until the pallet hits the back stop guide. See Fig. 9 The back stop tells the operator where the rear of the 1st cart is. Gently bumping the back stop guide successfully creates the correct spacing for the remainder of the carts in the lane.
- Page 13 Before lowering the pallet on to the cart, center pallet left-to-right by using your fork truck side shift controls. Fig. 11 Fig. 12 Load Centered Load Not Centered on Cart Improper centering of a pallet load on a push back cart, can lead to: •...
- Page 14 Slowly lower the pallet to gently set it on to the top cart. The pallet should overhang the front of the cart by 1". See Fig. 13 Diagram shows properly placed pallet, with 1” overhang on cart. 1” Overhang. Fig. 13 Do NOT Drop the load on to the push back carts.
- Page 15 Fig. 14 Step 1, place next load 3” above load in system. Make pallet-on-pallet contact. Step 2. Using the pallet on the fork truck, push the rear position pallet back slowly until the lower cart (the one you are trying to load) starts to move backward, and exposes the next cart.
- Page 16 Step 3. Again, center the pallet to the cart or rails and then slowly lower it into position on the cart. See Fig. 16 Fig. 16 Step 3, Slowly lower pallet on to open push back cart When loading the push back system, operators must make sure they are loading only one pallet per cart Failure to load only one pallet per...
- Page 17 Fig. 17 Cross Stacking due to first pallet placed too far back and sitting on top the back stop guide The operator is using a pallet shorter than what the push back cart was designed to hold. Example would be an operator loading a 36" deep pallet on a cart designed to hold a standard 48"...
- Page 18 Cross Stacking can cause pallet, cart, and/or rail damage and may cause the push back system to fail or become inoperable. If an operator notices a Cross Stacking situation has occurred, immediately remove the load that is over lapped and determine if the first load is too far back or is using the wrong size pallet.

Page 19: Proper Unloading Procedures
Proper Unloading Procedures: Fork truck operators need to tilt their forks slightly upward when unloading a pallet from a push back lane. See Fig. 19 Diagram shows Fig. 19 the proper angle of forks for unloading a push back system. Fig. - Page 20 Entering the lane with the forks tilted downward, may cause the forks to catch the underside of the center tube or rear tube of the cart. This could cause the carts to be accidentally dislodged from the system or damaged. Pick up the pallet and slowly pull back out of the system, controlling the speed of the remaining pallet loads in the lane.

Page 21: Fixing Jammed Systems
Fixing Jammed Systems: If during the unloading of a pallet load from a push back lane, should the pallet behind it not immediately flow for- ward, the fork truck operator should lightly bump the hung up pallet with the pallet being removed. This should free the pallet and allow it to flow forward. - Page 22 If at anytime your Steel King SK3600 Push Back system becomes jammed follow these safety steps: Steel King always recommends, and Federal, State and local safety codes require the use of fall protection equipment when working at elevated heights. Please follow the instructions provided with your fall protection equipment.
