Introduction

Material Handling refers to the total managements of all materials

& process involved in the entire manufacturing procedure. This

includes sourcing, Delivering, movement, protection & storage of

product.

Material Handling is the movement & storage materials at the

lowest possible cost through the use of proper methods and

equipments. Getting the right part to the right place involves a tight

synchronization of work cells.

Material handling plays a vital part in all type of industry towards

increase the productivity, reduce the in-process cost and safety

procedure at the work place.

Role of Material Handling in

Logistics

Unloading the incoming material from vehicles

Moving the unloaded material to the assigned

storage place

Lifting the material from its storage place duringorder picking

Moving the material for inspection and packing

Loading the packages, boxes or cartons on to thevehicles

Mechanized System

The prime consideration before going in for mechanized material handlingsystems is the layout of the warehouse.

The layout may create obstacles for the free movement of equipmentsand the goods.

Mechanized system bringing the speed and reliability in materialmovement.

Mechanized system enhances the system productivity.

The criteria for choosing a machine in the warehouse should be:o Improving space utilization.

o Reducing the time for material movement.

o Speeding up the overall material flow.

o Reducing the material damages during material handling.

o Should be safe for human beings to operate.

Mechanized System

Wheeled Trolley

The wheeled trolley are efficient for handling small volumes over ashort distance.

The two-wheeled hand trolley is simplest and versatile.

The four-wheeled hand-held trolley is called a platform truck.

They are capable of moving light loads.

For higher volumes and longer distances , use of powered trolleys arepreferred.

Mechanized System

Conveyors

Conveyors are used where continuous flow of material is required over

a long distance. The excel at straight transportation because they eliminate re-

handling before and after each function.

They are also used in sorting and merging operations.

The most common usage are:o Baggage handling at airports.

o Coal handling at thermal power stations.

o Iron ore handling at integrated steel plants.

Mechanized System

Overhead Cranes

These cranes are used for moving very heavy items over a short

distance.Such as:

o Steel plates.

o Bars.

o Coils.

o Machinery components.

These are used where large heavy items or containers have to be

moved in and out of the warehouse.

Mechanized System

Pneumatic Tube

Pneumatictube systems are used for movement of granular and

powdered material over a short distance.

These systems are quite common in the cement and fertilizer plants

where the material in powdered form is moved to the storage silosusing the Pneumatic flow.

The air pressure of 7 kg/cm2is normally used for transporting the

material which carries the powder in the direction of the flow.

This system is used for storage and retrieval of the material.

For bulk transfer, these systems are cost effective and reliable.

In semi-automatic system all mechanized handling equipments may be

used but the specific handling requirement for a particular warehouse

operation may be performed automatically.

The semi-automatic warehouse is a mixture of mechanized and automatic

handling equipments.

The following are various types of automated equipments in semi-

automatic warehouse system:

o Sorting Device

o Robotics

o Automatic Guided vehicle

Automatic System

The automated material systems are custom built and attract heavy

investments.

The advantages are speed and accuracy, which enhance the productivity

of the system.

The system is connected to the computer for programming the equipmentoperations, material pick-up route, packing and loading instructions.

Introduction

The ultimate goal of any material storage system is to have ease inmaterial placement and retrieval, ensuring space efficiency andminimum time in tracking, tracing and pickup.

The inventory manager can built storage space with higher storagedensity so as to have higher warehouse occupancy.

Proper selection of storage system can result in effective use ofwarehouse space and efficiency.

Investment in proper development of facilities and equipment usingmodern techniques will pay back handsomely in terms of labour,time and money.

Unit Load Storage

The unit load is constructed by bringing together a number of individual

items of identical configuration so as to built up a large load which ensures

convenience during storage and transportation.

The most commonly practised method is to build load on the raisedplatform . This platform is called Pallet.

The other method is to construct a platform to fit the load . This is called

Skid.

Storage Principles

The storage system in warehouse has important bearings on the total

cost and success of warehousing operations.

A well designed storage system is a compromise between maximum

utilization of the available space and need for easy and quick access to

the stored goods.

The following rules are followed for designing an effective storage

system:

o Minimize the travel distance.

o Maximize the utilization of available space.

o Provide easy and quick access to the stored goods.

o Facilitate easy tracking of the material.

o Provide security against fire, damage and theft.

o Prevent contamination and deterioration of the goods.

Storage Design Benefits

Proper planning of the storage system helps in improving the efficiency of

the entire logistics system . This helps in speedy movement of goods

across the supply chain which results in improving system productivity.

Space Economics

Enhance Throughput

Ease in Material Location and Tracking

Security, Safety and Housekeeping

Storage Methods

Block Storage

Stacking is done on the floor or on the wooden platform. However, block

stacking has limitations on the stack height due to following reasons:

Load bearing capability of the package ( box, carton, container) at the bottom of thestack.

Sensitivity of the product insight the pack to load.

Ease in loading and unloading.

Storage Methods

RackingSystem Racks are used for storage of items longer in length, small containers,

boxes and pallets etc.

The stationary rack structure is built by getting support from wall and

roof of the warehouse building.

The drive-in racks closed at one end are suitable for last-in-first-out

(LIFO) inventory technique while racks which are open at both ends

may be used for FIFO technique.

Storage Methods

Shelving System

Shelving systems are in use for non-palletized or non-uniform type of

loads.

Shelving is the most flexible and costeffective storage structure

which is available in modular configuration to suit storage volumes

and product configurations.

Storage Methods

Pallets

Pallets are specially designed platforms for storage of goods with a

view of moving the whole load by forklift whenever it is required.


28/30

Storage Methods

Containers

Containers are most commonly used in manufacturing plants for in-

process material handling applications.

They are quite popular in engineering industry because they help to

increase productivity, space utilization and facilitate fast materialmovement.

Different types in use are as follows:

o Welded Wire
