PIT STOP 2: Storage Equipment - Storage Carousel, Drive-Through & Drive-In Rack

(1) Storage Carousel

=> Carousel consists of a set of vertically or horizontally revolving storage baskets or bins (picture shown above is a Vertical Storage Carousel)
=> Materials and the storage medium move to the operator (part-to-man), for
end-of-aisle picking
=> Each level can rotate independently in a clockwise or counter-clockwise direction

(2) Drive-Through Rack

=> Loads supported by rails attached to the upright beams
=> Lift Trucks driven between the upright beams
=> Open at both ends, allowing access from both ends (FIFO)

(3) Drive-In Rack

=> Similar as Drive-Through Rack, except that it is closed at one end, allowing entry from only one end (LIFO)

Breakdown!! PIT STOP 1

Trail TWO
PIT STOP 1: Storage Equipment - Automatic Storage/Retrieval Systems (ASRS)

ASRS consists of an integrated computer-controlled system that combines the storage medium, transport mechanism, and controls with various levels of automation for fast and accurate random storage of products and materials.

Major Types of ASRS:

(1) Unit Load ASRS

=> Used to store or retrieve loads that are palletized or unitized and weigh over 500 lbs
=> Stacking heights are up to 130 feet high

(2) Miniload ASRS

=> Used to store or retrieve small parts and tools that can be stored in a storage bin or drawer
=> Stacking heights range from 12 to 20 feet

(3) Man-On-Board ASRS

=> Used for in-aisle picking, operator picks from shelves or drawers within the storage structure
=> Manual or automatic control

(4) Deep-Lane ASRS

=> Similar to unit load ASRS, except loads can be stored to greater depths in the storage rack
=> A rack-entry vehicle is used to carry loads into the racks from the storage retrieval machine and is controlled by the machine

Breakdown!!

Trail TWO: Storage Equipment

Storage equipment is used for holding or buffering materials over a period of time.

Sub-categories of transport equipment and examples:

(1) Automatic Storage/Retrieval Systems (AS/RS)
=> Unit Load AS/RS
=> Miniload AS/RS
=> Man-On-Board AS/RS
=> Deep-Lane AS/RS

(2) Storage Carousel

(3) Drive-in & Drive-Through Rack

Journey Continues - 3rd STOP

Trail ONE 3rd STOP : Transport Equipment - INDUSTRIAL TRUCKS

Industrial trucks are used to transport materials over variable paths, with no restrictions on the area covered by the movement.

Major Types of Industrial Trucks:

(1) Pallet Jack

=> Pallet Restrictions: reversible pallets cannot be used and double-faced nonreversible pallets cannot have deckboards

(1.1) Manual Pallet Jack
=> Manual lifting and travel

(1.2) Powered Pallet Jack
=> Powered lifting and travel

(2) Narrow Aisle (NA) Truck

(2.1) NA Straddle Truck

=> Minimum aisle width requirement is 7-8 feet
=> Less expensive than NA reach truck

(2.2) NA Reach Truck

=> Minimum aisle width requirement is 8-10 feet
=> Reaching capability enables the use of shorter outrigger arms as compared to NA straddle truck

(3) Turret Truck

=> Greater stacking height compared to other narrow-aisle trucks but greater investment cost
=> Transport greater-than-pallet-size load

(3.1) Operator-Down Turret Truck
=> Operator not lifted with the load
=> Minimum aisle width requirement is 5-6 feet

(3.2) Operator-Up Turret Truck
=> Operator is lifted with the load to allow precise stacking and picking
=> Minimum aisle width requirement is 5-7 feet

Journey Continues - 2nd STOP

Trail ONE 2nd STOP : Transport Equipment - CRANES

Cranes are used to transport materials over variable paths within a restricted area.

Major Types of Cranes:

(1) Gantry Cranes

=> Types of Gantry Cranes - Single leg, Double leg and Mobile types
=> Can be fixed in positions or travel on runways
=> Can be used outdoors when it is supported at both ends

(2) Jib Cranes

=> A hoist is attached to the arm for lifting
=> It can function as a manipulator for positioning tasks
=> Its arm can rotate 360°

(3) Stacker Cranes

=> Used for storing and retrieving unit loads in storage racks, especially in high-rise applications (more than 50 feet high)
=> Can be controlled remotely or manually by an operator
=> Can be rack-supported

Journey Continues...1st STOP

Trail ONE 1st STOP: Transport Equipment - CONVEYORS

Conveyors are used to transport materials over a fixed path.

Major types of Conveyors:

(1) Roller Conveyors
(1.1) Gravity Roller Conveyors

=> Subsitution to wheel conveyors
=> Suitable for Heavy-duty applications

(1.2) Live (Powered) Roller Conveyors

=> Belt or Chain driven
=> Provides limited incline movement capacity

(2) Wheel Conveyors

=> A series of skatewheels mounted on a shaft or axle, where the spacing of the wheels is dependent on the load being transported
=> Suitable for Light-duty applications
=> Cheaper compared to Roller conveyor

(3) Flat Belt Conveyors


=> Provides considerable control over the orientation and placement of the load
=> Suitable for Light or Medium-weight Loads

Journey Begins...

Materials Handling Equipments are commonly used for the movement and storage of materials within the area.

Classified into 5 major categories :
- Transport Equipment
=> The equipment is used for movement of materials from one place to another.
- Positioning Equpiment
=> The equipment is used for handling of materials at the single area to make sure that material is at the correct place for subsequent handling, machining, transport and storage.
- Unit Load Formation Equpiment
=> The equipment is used to restrict materials so as to maintain their integrity when handling a single load when transport and storage.
- Storage Equipment
=> The equipment is used to hold or buffer materials over a period of time.
- Identification and Control Equipment
=> The equipment is used to retrieve and communicate the information that is used to coordinate the flow of materials within and between the plant and its suppliers and customers.
