Components of Material Handling
  • The Materials products, items, substances
    and/or people which are being moved, transported,
    or physically relocated.
  • The Move (origin, travel path, destination,
    frequency) to be made.
  • The Method (equipment, people, procedures,
    physical facilities) to be used to make the move

Material Handling Equipment
Material handling equipment (MHE) is used for the
movement and storage of material within a
facility or at a site. MHE can be classified
into the following five major categories Transpo
rt Equipment Equipment used to move material
from one location to another (e.g., between
workplaces, between a loading dock and a storage
area, etc.). The major subcategories of transport
equipment are conveyors , cranes, and industrial
trucks. Material can also be transported
manually using no equipment.
8
Material Handling Equipment
Positioning Equipment. Equipment used to handle
material at a single location so that it is in
the correct position for subsequent handling,
machining, transport, or storage. Unlike
transport equipment, positioning equipment is
usually used for handling at a single workplace.
Material can also be positioned manually using no
equipment. Unit Load Formation Equipment.
Equipment used to restrict materials so that they
maintain their integrity when handled as a single
load during transport and for storage. If
materials are self-restraining (e.g., a single
part or interlocking parts), then they can be
formed into a unit load with no equipment.
9
Material Handling Equipment
Storage Equipment. Equipment used for holding or
buffering materials over a period of time. Some
storage equipment may include the transport of
materials (e.g., the S/R machines of an AS/RS, or
storage carousels). If materials are block
stacked directly on the floor, then no storage
equipment is required. Identification and
Control Equipment. Equipment used to collect and
communicate the information that is used to
coordinate the flow of materials within a
facility and between a facility and its suppliers
and customers. The identification of materials
and associated control can be performed manually
with no specialized equipment.
10
Material Handling EquipmentTransport Equipment
The major subcategories of transport equipment
are Conveyors. Equipment used to move materials
over a fixed path between specific points.
Cranes. Equipment used to move materials over
variable paths within a restricted area.
Industrial Trucks. Equipment used to move
materials over variable paths, with no
restrictions on the area covered by the movement
(i.e., unrestricted area). No Equipment.
Material can also be transported manually using
no equipment.

Conveyors
  • Conveyors are used
  • When material is to be moved frequently between
    specific points
  • To move materials over a fixed path
  • When there is a sufficient flow volume to justify
    the fixed conveyor investment
  • Conveyors can be classified in different ways
  • Type of product being handled unit load or bulk
    load
  • Location of the conveyor overhead, on-floor, or
    in-floor
  • Whether or not loads can accumulate on the
    conveyor

Cranes
  • General characteristics of cranes
  • Used to move loads over variable (horizontal and
    vertical) paths within a restricted area
  • Used when there is insufficient (or intermittent)
    flow volume such that the use of a conveyor
    cannot be justified
  • Provide more flexibility in movement than
    conveyors
  • Provide less flexibility in movement than
    industrial trucks
  • Loads handled are more varied with respect to
    their shape and weight than those handled by a
    conveyor
  • Most cranes utilize hoists for vertical movement,
    although manipulators can be used if precise
    positioning of the load is required

Trucks
The powered industrial trucks are used for moving
either mixed or uniform loads intermittently over
various paths. While these paths can be somewhat
random at the discretion of the driver, the paths
are restricted to suitable indoor or outdoor
surfaces. These trucks are used for moving

36
Material Handling EquipmentPowered Industrial
Trucks
Industrial trucks provide not only a means of
transporting materials, but also provide a means
of accurate lifting and stacking. Appropriate
tooling for the truck permits users to lift not
only pallets, but a wide array of specialized
loads. For example, rolls of carpet are easily
moved via industrial truck by replacing standard
forks with a single tube.

Slides 37-50 are supplemental to already
published CICMHE Material Handling Taxonomy.
These slides are created using literature from
the Industrial Truck Association and the
document, An Introduction to Material Handling
Equipment Selection1 edited by Brett A. Peters.
Powered industrial trucks can be found in almost
any manufacturing plant, loading dock, or
warehouses. Powered industrial trucks are made
by a variety of manufacturers for diverse
purposes, including some highly specialized
applications. Internal combustion trucks add
the advantage of outdoor use. They can lift
2,000 to 15,000 pounds with some specialty trucks
lifting up to 50 tons. They can lift up to 20
feet in height and can operate on gasoline,
LP-gas, or diesel fuel.
38

The Industrial Truck Association (ITA) has
classified the powered trucks into seven classes
which are Class 1 Electric Motor Rider
Trucks Class 2 Electric Motor Narrow Aisle
Trucks Class 3 Electric Motor Hand Truck Class
4 Internal Combustion Engine Trucks Cushion
Tires Only Class 5 Internal Combustion Engine
Trucks Pneumatic Tires Only Class 6 Electric
and Internal Combustion Engine Tow Tractors Class
7 Rough Terrain Fork Lift Trucks Each of the
classes are divided into lift codes. See the
ITA Pictorial Model Listing.
39
Material Handling EquipmentPowered Industrial
Trucks
The first five classes are the most common.
Detailed information is available through the
ITA. Electric Motor Rider Trucks are general
purpose trucks and are used primarily indoors.
These trucks can lift up to 6 tons and up to 18
feet in height. Electric Motor Narrow Aisle
Trucks are used in narrow aisle applications.
These trucks are used primarily for
storage/retrieval in applications similar to
AS/RS functions. They can easily lift loads from
2,000 to 4,500 pounds to heights of 40 feet.
40
Material Handling EquipmentPowered Industrial
Trucks
Electric Motor Hand Trucks are generally used for
indoor applications and can handle loads up to 4
tons. These trucks are perfect for situations in
which material is to be moved from one location
to another without the need for lifting more than
a few inches. For example, this type of truck is
commonly used in grocery stores to move pallet
loads of cans or boxes to a display location
within the store. An added convenience is that
the operator can move among customers in the
store safely and without obstructed views.
41

Internal Combustion Trucks add the advantage of
outdoor use. They can lift 2,000 to 15,000
pounds with some specialty trucks lifting up to
50 tons. They can lift up to 20 feet in height
and can operate on gasoline, LP-gas, or diesel

Material Handling EquipmentPositioning Equipment
Positioning equipment is used to handle material
at a single location so that the material is in
the correct position for subsequent handling,
machining, transport, or storage. Unlike
transport equipment, positioning equipment is
usually used for handling at a single workplace.
Material can also be positioned manually using no
equipment.
52
Material Handling EquipmentPositioning Equipment
As compared to manual handling, the use of
positioning equipment can provide the following
benefits Modern Materials Handling, Sept. 1993
  • raise the productivity of each worker when the
    frequency of handling is high,
  • improve product quality and limit damage to
    materials and equipment when the item handled is
    heavy or awkward to hold and damage is likely
    through human error or inattention, and
  • reduce fatigue and injuries when the environment
    is hazardous or inaccessible.

Equipment
Unit load formation equipment used to restrict
materials so that they maintain their integrity
when handled a single load during transport and
for storage.
  • Advantages of unit loads
  • More items can be handled at the same time,
    thereby reducing the number of trips required
    and, potentially, reducing handling costs,
    loading and unloading times, and product damage.
  • Enables the use of standardized material handling
    equipment.
  • Disadvantages of unit loads
  • Time spent forming and breaking down the unit
    load.
  • Cost of containers/pallets and other load
    restraining materials used in the unit load
  • Empty containers/pallets may need to be returned
    to their point of origin.

Material Handling EquipmentStorage Equipment
Storage equipment used for holding or buffering
materials over a period of time. The most common
reason for storing a product allows the other
elements of production to operate more
efficiently on a per-unit basis because the fixed
costs associated with utilizing the element can
be spread over more products e.g., storing up to
a truckload of product in a facility reduces the
per-unit costs of shipping and buffering or
storage of WIP enables batch production which
reduces the per-unit setup costs.
63
Material Handling EquipmentStorage Equipment
Other potential reasons for storage include time
bridgingallows product to be available when it
is needed (e.g., storing spare machine parts at
the facility) processingfor some products
(e.g., wine), storage can be considered as a
processing operation because the product
undergoes a required change during storage and
securinge.g., nuclear waste storage.

Material Handling EquipmentIdentification and
Control Equipment
Identification and control equipment is used to
collect and communicate the information that is
used to coordinate the flow of materials within a
facility and between a facility and its suppliers
and customers.
Manual (no equipment) Bar codes Radio frequency (RF) tag Magnetic stripe Machine vision Portable data terminal Electronic data interchange (EDI)/Internet
72
Material Handling EquipmentIdentification and
Control Equipment
  • Manual (No Equipment)
  • The identification of materials and associated
    communication can be performed manually with no
    specialized equipment
  • Although it is sometimes possible to manually
    coordinate the operation of a material handling
    system, it becomes more difficult to do so as the
    speed, size, and complexity of the system
    increases

73
Material Handling EquipmentIdentification and
Control Equipment
  • Bar Codes
  • Unique bar/space patterns represent various
    alphanumeric characters
  • Bar code system consists of bar code label, bar
    code scanner, and bar code printer
  • Contact bar code scanners use pen or wand to read
    labels
  • Non-contact bar code scanners include fixed beam,
    moving beam, and omni-directional
  • 1-D codes are most common 2-D codes enable much
    greater data storage capability

74
Material Handling EquipmentIdentification and
Control Equipment
  • Radio Frequency (RF) Tag
  • Data encoded on chip encased in a tag
  • Non-contact can be read when the tag is within
    30 ft. of an antenna
  • Tags can either be attached to a container, or
    permanently or temporarily to an item
  • RF tags have greater data storage capability than
    bar codes

75
Material Handling EquipmentIdentification and
Control Equipment
  • Magnetic Stripe
  • Data encoded on a magnetic stripe that is
    readable in almost any environment
  • Requires contact with a reader
  • Greater storage capability and more expensive
    than bar codes

76
Material Handling EquipmentIdentification and
Control Equipment
  • Machine Vision
  • Does not require explicit encoding of data since
    objects can be identified by their physical
    appearance
  • Non-contact, but typically requires structured
    lighting
  • More flexible than other identification
    equipment, but less robust

77
Material Handling EquipmentIdentification and
Control Equipment
  • Portable Data Terminal
  • Handheld, arm-mounted, or vehicle-mounted data
    storage and communication device
  • Communicates with a host computer via a radio
    frequency or infrared link
  • Variety of input devices available keyboard, bar
    code scanner, voice headset

78
Material Handling EquipmentIdentification and
Control Equipment
  • Electronic Data Interchange (EDI)/Internet
  • Electronic data interchange (EDI) provides
    standards for inter-corporate transfer of
    purchase orders, invoices, shipping notices, and
    other frequently used business documents
  • Prior to the Internet, EDI required expensive
    dedicated value added networks (VANs)
  • EDI is critical for implementing JIT manufacturing

Deciding on a Picking Medium in Picking
Operations As part of warehousing operations and
specifically in picking operations,
identification of the parts and their locations
can have an impact on the picking speed. The
following are the most commonly used mechanisms
for communicating picks to order pickers
  • Label Picking
  • Pick to Light
  • Radio Frequency Barcode Picking
  • Voice Picking

Material Handling EquipmentSafety and Ergonomics
Scientific research shows an increase in injuries
at certain levels of exposure to heavy, frequent
and awkward lifting (Washington State Department
of Labor and Industries, http//www.lni.wa.gov). J
ob design is very important in creating a safe
and healthy work environment and the selection of
proper material handling devices can help with
reducing some of the material handling related
injuries.
