DRIVE-IN RACKING
When a pallet is being placed into a drive-in rack, the following sequential loading activities take place:
- The forklift truck drives with a pallet to the pallet storagelocation.
- The driver raises and maneuvers the pallet into the racking lane, clear of the rack uprights, with no forward tilt on the forks, at the required storage level and with the pallet load positioned centrally between the uprights or guard rails.
- The truck is then driven forward from the entry to the set down position keeping the pallet and truck mast clear of contact with the beam rails or other parts of the drive-in rack structure.
- The driver lowers the pallet carefully onto the beam rails, releasing the load from the forks. Once in contact with the beam rails the pallet must not be slid or dragged along or across these supporting members.
- The driver takes the forks out of the pallet, reverses the truck carefully back out of the lane and then lowers the forks.
Recommended loading and unloading sequence for Drive-In-Racking
In Drive-in racking the sequence of placement of loads should be followed. On the input cycle the first pallet is placed at position 1and the rack is loaded from the bottom upwards and from the back outwards. On the output cycle the procedure is the exact reverse, from the top-down working in towards the back of the drive-in rack.
Pallet specification for drive-in racking
The specification of pallets used in drive-in racking shall include fora quality of pallet that when loaded with the specified goods to be stored shall not deflect more than the pallet span/l00 when supported on the beam rails with a minimum bearing on one side of 20mm. The pallet span is the nominal clear dimension between the beam rails.
MHE speed in the drive-in racking lanes.
The speed at which the forklift truck is driven in the rack storage lanes is critical to the safe operation of the storage system. To prevent the mast from flexing and swaying excessively on uneven floors and striking the beam-rails, the truck speed must be regulated by the driver to suit the floor flatness and the mast flexibility.
