Materials Handling

• Materials handling is the primary activity of every manufacturing organization and it is estimated that at least 15 to 25% of the product cost is attributed to materials handling activities.

• Definition—Materials Handling is a Art and science of movement ,handling and storing during different stages of manufacturing ,

Important factors

• Creation of time and Place utility.• Movement of materials at lowest cost ,by

using proper methods and equipment.

Functions of materials handling

• Movement of materials for the purpose of storage,

• Internal movement of materials from stores to production shop.

• Movement of semi-finished materials to next operation.

• Movement of finished product to stores for dispatch.

Scope of materials • The scope of materials Handling activity within

organization depends on the type of the product depends on the type of the product manufactured , size of the organization ,the value of the product and the value of activity being performed .

• There are three types of .• 1- Traditional point of view.• 2-Plant wide concerned.• 3-The system point of view of materials

handling

Importance of materials Handling

• Efficient materials Handling – manufacturing operations.

• materials Handling analysis.-is a subset of plant layout.

• 30 to 40 % cost of production involved in materials Handling .

• 50% of the production cycle time is spend on• materials Handling. materials Handling

Objectives of materials Handling• Lower unit materials handling cost.• Reduced in manufacturing cycle time. Through

faster movement of materials • Contribution towards a better control of flow of

materials through the manufacturing facility. • Improve the better working conditions and

greater safety.• Contribute to better quality by avoiding damage

to product by inefficient handling• Increase storage capacity.• Higher productivity at lower cost.

Materials handling principles

• principles are • 1-Eliminater handling.• 2- Keep moving• 3-Use simple pattern of materials flow.• 4-carry pay load both way.• 5-Carry full load.-• 6-Use gravity

Materials handling cost

• Cost of materials handing arise from two sources .

• 1- the cost of owning and maintaining equipment

• 2- cost of operating system.

Reduce handling cost,

• There are three fundamental ways of minimizing the cost.

• 1-Eliminate hand itself.• 2-Mechanising.• 3-making handling more efficiently.

Factors influencing materials Handling

• 1-Layout decisions.• 2-Wroung selection of handling equipments.

Principles of materials handling• materials handling principles can basically be grouped into fie

categories.• 1-Planning principles –a) Plant layout principle b)Delegation of

responsibility principle Min.re-handing principle. d)-speed saving principle

• 2-Operating principles-a) Unit load Handling principle b)Gravity principle .c)Flow of materials principles.

• 3-Eqwuipmenrt Principles-Mechanization principle, Terminal Time principle. Dead weight principle. Standardization principle. Maintenance principle, Speed principle Versatility principle,

• 4-Costing principle—Equipment selection principle, Replacement principle, Handling cost Appraisal Principle.

• 5-General Principles-Safety principles., Training principles., Identification principles , Location principles. Materials treatment principles

SELECTION OF MATERIALS HANDLING equipments• Factors to be considered • Materials to be handled.• Plant building.• Layout.• Speed equipment.• Materials Flow pattern.• Methods of production• Distance.• Safety requirements.• Installation and operating cost.• Maintainace of materials handling equipment• Skill requirement• Flexibility of materials Handling equipment• Human factor‘
