 Conventional
Pallet Storage
Conventional pallet storage is used in warehouses
that require the following three conditions for effective inventory control:
1. They need to store pallets according to individual skus that are
systematically categorized
2. They need rapid fork truck access to each
individual pallet.
3. The need plenty of aisle space for fork trucks to move
up and down the aisles to retrieve pallets at will.
In larger warehouses, most conventional pallet storage is single-depth. In
smaller facilities where space is limited, pallet racks can be built double
depth to allow one pallet to be stored behind the other, thus doubling storage
space without the need to add additional decks or aisles.
Drive-In Pallet Storage
Warehouses need pallet racks
built in the drive-in design any time they face the following circumstances:
1. They need to convert 70-85% of their available floor space and vertical
cube into organized pallet storage.
2. They experience low turnover of
homogenous products and thus leave pallets on the rack for extended periods of
time.
3. They cannot afford to waste any floor space at all on multiple
aisles.
The drive in design allows for pallets to be stored on the inside of the
racking system. An entrance allows forklifts to drive into the rack itself to
retrieve them. This makes the most of floor space in cramped quarters, and is
especially useful in warehouses with taller ceilings where a great deal of
vertical space can also be converted into inventory storage space.
Live Pallet Storage
This design is used a great deal in
food product and pharmaceutical storage facilities that need to make the most of
available space and maximize turnaround time. It is ideal for any warehouse that
requires any or all of the following:
1. A need to minimize retrieval time so pallets can be unloaded from the rack
more quickly and taken to trucks.
2. A simple, non-motorized means of moving the pallets to forktrucks without forktrucks having to go to them.
3. A
low-maintenance system that offers a predictable pace with minimal likelihood of
system failure.
Live storage racks actually move pallets to waiting forklifts by using
gravity as a force of motion. A slight incline in the rack allows a pallet to
slide toward the end of the system to be picked up. When it is retrieved,
another one slides in right behind it.
Push-back pallet storage
The push back system works in
much the same way as the live pallet storage system, although it uses trolleys
and rolling rails in addition to the force of gravity. When a pallet is removed
from one end, the others slide down slightly to fill the gap. Loading and
unloading is easily done from the central aisle.
Mobile Pallet Storage
1. When a warehouse needs to reduce
the number of aisles between racks, increase its total capacity, AND maintain
individual, direct access to each and every pallet, it uses mobile pallet
storage,
2. The entire rack rests on a motorized base that can be moved
either with manual controls or remote PC.
