the top deck that serve as strengtheners and posts
Blow-molded Pallet
A pallet manufactured by heating a plastic material and extruding it
into tubing. A section is cut to the desired length to create a parison that is
then introduced into a mold cavity. Air is introduced into the parison to
inflate the parison until it conforms to the geometry of the mold. When the
part is fully formed and cooled, it is released from the mold for secondary
operations such as machining and trimming
Bulk Bin
Plastic or metal bins that are designed to handle larger or "bulk" quantities
of materials or merchandise. Bulk bins tend to large in size relative to other
types of bins and are generally designed to be higher capacity in terms of load
capabilities.

Injection-molded Container/ Injection Molded Pallet
Plastic material is introduced in pellet form into a "hopper" positioned at the
top of a machine and forcing it along a horizontal chamber or "barrel" of an
extruder by means of the rotation of a screw. The plastic material is heated as
it moves through the barrel so when it reaches an open cavity, it is a molten
mass ready to assume the configuration of the mold. The mold is closed and
pressure is applied to form the container. Once the pallet is cooled and taken
from the mold, it can be further processed into secondary operations such as
painting, trimming or fastening

Pallet
Generally constructed of plastic, metal, or wood, a pallet is a piece of
transportation/movement equipment utilized in the movement of unit loads.
Usually "fork-liftable" in that it is designed to accept forks between the top
and bottom platforms of the unit.
Pallet Dimensions
Measurement points to determine a pallet's dimensions:
Length = distance between pallet ends (inclusive of overhang) and parallel to
the stringer(s).
Width = distance between pallet sides at right angles to the pallet length
inclusive of any overhang.
Height = distance from the outer edges of the bottom deck boards to the outer
edges of the top deck board.
Pallet dimensions are generally shown in inches.

as a pallet dispenser.
Pallet Double Wing

opposite sides.
Pallet Exchange
Program
A program agreed upon by several shippers and receivers with each party
assuming responsibility for the total inventory of pallets. These parties
exchange pallets on a one-for-one basis with each transaction recorded and
documented. Program provides cost savings in off loading time and time
pressures on warehousing personnel.
Pallet Length
The first dimension stated in categorizing or describing a pallet
Pallet Life

trips that the pallet has been in service.
Pallet Pattern
The layer-by-Ayer arrangement or pattern of boxes/cartons as they are placed on
a pallet.
Pallet Performance
The performance of a pallet as expressed in terms of durability, stability
(lateral), degree of stiffness or rigidity, and strength.
Pallet Rack
A single or multi-level structural storage system that is utilized to support
high stacking of single items or palletized loads. Pallet Truck A
manually-powered fork truck. The operator physically pushes the forks into the
opening on the pallet and "jacks" the ratcheting lift mechanism so as to raise
the pallet off the floor. Once lifted, the load can be manually moved from
place to place.
Pallet-stacking Frame
A load-securing device that often can take the place of containers or bins.
This device consists on iron posts and connecting frame members resting on the
four corners of a pallet creating an open container in appearance with a
certain amount of load retention ability. The frames are removable for storage,
but when in use, the loaded pallets can be block stacked on the floor. This is
a particular advantage for unit loads that would not stack safely without the
rigid frame. There are other attachments such as special metal frames and
welded wire gates, but none of these allow for pallet stacking.
Palletizer
Palletizers are special machines capable of building a complete unit load on a
pallet. Although the most common application is for cases, some palletizers can
also handle sacks and bags. A less common palletizer application would be for
special products such as sheet stock. There are two general methods employed
for automatically building a full pallet. One makes use of a fixed position or
overhead gantry robot with end effectors suited to the individual loads, such
as vacuum lifts or a gripper. The other method employs more complex mechanisms
for forming pallet layers off line, one at a time, and then shifting or
transferring each successive layer onto the pallet as it is lowered via a
lift/lower table.
Picker Pallet
A pallet used in distribution operations wherein the center stringer or block
is grabbed by a center clamp to steady the pallet, enabling goods to be stacked
on it at an elevated height.
Plastic Pallet
A device used for moving and storing freight. It is used as a base for
assembling, storing, stacking, handling, and transporting goods as a unit load.
Commonly, it is about four feet square and is so constructed to facilitate the
placement of a lift truck's forks between the levels of a platform so it may be
moved easily. A pallet molded from plastic or made up of plastic components.
Portable Rack
Self-contained steel rack units made up of bases and/or decks and posts.
Portable rack may be welded or collapsible units either having a knockdown
feature which can be a space saver when units are not in use.
Push-back Rack
Utilizing wheels in the rack structure, this rack system allows palletized
goods and materials to be stored by being pushed up a gently graded ramp.
Stored materials are allowed to flow down the ramp to the aisle. This rack
configuration allows for deep storage at each rack level.

S
Single-deck Pallet
A pallet possessing one load-bearing deck.
Skid
A pallet that does not utilize a bottom deck. Generally supports the top deck
by means of blocks and stringers.
Slave Pallet
A pallet used in an automated rack system.
Solid-deck Pallet
A pallet constructed with no spacing along the deck(s).
Stack-and-nest Container
A combination container that has both stacking and nesting features. Can be
stacked ands nested in 90 degree and 180 degree combination.
Stack-only Container
A container that possesses self-supporting and straight walls. This feature
means that the container walls are straight and can support the total weight of
several stacked containers. Stackability reduces the required floor or rack
storage space for empty containers.
Stackable Container
Hand-held container that can be stacked or nested when turned 180 degrees.
Stacking Pallet
A pallet constructed in such a manner as to allow one pallet complete with load
to be placed on another without damage to the lower unit load. This is
generally achieved by utilizing a superstructure within the pallet.
Straight-wall Container
A container made from plastic or metal whose walls are not corrugated but are
indeed straight walls with no ridges or perforations.
Strapping
A load-stabilizing and securing method wherein a variety of materials can
literally be used to wrap or tie down a load or individual item for movement
and protection. These materials include cold-rolled, low- and medium carbon
steel; hot-rolled, high-tension steel; polyester; nylon; and polypropylene.
Each of these materials has special properties that need to be closely matched
to the load requirement.
Structural Foam-molded Pallet
Structural foam molding is a variation of the injection-molded process whereby
a compounded plastic material is introduced into an extruder in pellet form,
heated to a molten state, and then formed by means of a rotating- screw into
one or more mold cavities. The material adopts the configuration of the mold;
and, once cooled, it is injected as a fully formed pallet. With structural foam
molding, a blowing agent is introduced to and mixed thoroughly through the
plastic prior to its injection into the mold cavities. The heating process
activates the blowing agent and creates a cellular structure within the molten
material. This cellular structure not only saves on raw material requirement,
but it produces a part with an elevated strength-to-weight ratio.

Throwaway Pallet
A pallet whose planned usage is limited to one use and then is discarded.

non-reversible pallet. Type II Pallet: Double-faced, flush-stringer or block,
non-reversible pallet. Type III Pallet: Double-faced, flush-stringer or block,

Uniformly Distributed
Load
The per-square-inch weight of the pallet load does not vary from one point to
another on the pallet. Indicates that the load on a pallet is evenly
distributed. Any static load that is evenly distributed over the entire surface
of the rack deck. A load, as on a shelf, or pair of load beams, supported by
all, or nearly all of the shelf or beam supporting surfaces
