News: tips on designing selective pallet rackings
1. How to determine the width and depth of pallet racking?
A pallet and its entry side determines the width and depth of a pallet racking. Four-way entry pallets permit entry of forks from each side, two-way entry pallets only permit entry of forks from two opposite directions only. A 2-way entry pallets will restrict the direction you place the pallets on the racking.
For two pallets per beam level, a 2300(W) x 1000mm(D) rack is suitable for placing typical 1200 x 1000mm pallets with entry side at 1000mm direction:

Make sure the pallets should overhang beams at least 50mm to 100mm at each end. Clearance of 70mm to 100mm between adjacent pallets and pallet and upright.should be allowed. If the entry side of the pallets is at 1200mm direction, a rack of 2700(W) x 900mm(D) will be used:

2. How to decide the beam level of a rack?
The height of your palletized load is needed for deciding the beam level. And the height of your palletized load is the sum of the height of loaded goods and the pallet itself. A clearance of 100mm should be allowed between the top of the load and the underside of the beam to enable the lifting action of forklift.

3. How to determine the height of racking?
First of all, the height of the top beam must be reached by your forklift truck. then the height of the rack with palletized goods should not exceed the height of the building. When
deciding the height of the top beam, make sure there is enough space for storing goods beneath the ceiling.
4. How to determine the aisle width between racking?
The aisle width is the distance between racks. The turning radius of the forklift truck determines the width of the aisle。"working aisle" width which is the clearance between palletized goods after put on the racking. The aisle width is determined by the turning radius of the forklift truck. Forklift truck requires wider aisle than reach truck.
Although a minimum aisle width is suggested by forklift manufacturer, it is advisable for actual layout design to increase the width by approximately at least 200mm. For instance, a counter balance forklift of 3.0T capacity needs approximately 3,500mm to operate, however it`s necessary to take into consideration the pallet size, the bigger the pallet is, the bigger the aisle width is.
