MATERIAL HANDLING

What is material handling????

Material Handling is the movement, storage, control and protection of materials, goods and products throughout the process of manufacturing, distribution, consumption and disposal. The focus is on the methods, mechanical equipment, systems and related controls used to achieve these functions. The material handling industry manufactures and distributes the equipment and services required to implement material handling systems. Material handling systems range from simple pallet rack and shelving projects, to complex conveyor belt and Automated Storage and Retrieval Systems (AS/RS). Material handling can also consist of sorting and picking, as well as automatic guided vehicles.

Material handling is the function of moving the right material to the right place in the right time, in the right amount, in sequence, and in the right condition to minimize production cost.

MATERIAL HANDLING

A material-handling system can be simply defined as an integrated system involving such activities as handling, storing, and controlling of materials.

The word material has very broad meaning, covering all kinds of raw materials, work in process, subassemblies, and finished assemblies.

MATERIAL HANDLING

Objectives

1) Reduced Costs

2) Increased Capacity

3) Improved Working Condition

4) Value Addition to Products

In brief, the primary objectives of Material Handling are;1. To save money2. To save time3. To save men

Main objective is to reduce the number of handlings as well as the overall cost of material handling equipment and reducing the distances through which the materials are handled.

The primary objective of using a material handling system is to ensure that the material in the right amount is safely delivered to the desired destination at the right time and at minimum cost.

objectives

The material handling system is properly designed not only to ensure the minimum cost and compatibility with other manufacturing equipment but also to meet safety concerns.The cost of MH estimates 20-25 of total manufacturing labor cost.

Objectives

Lower unit material handling costs

Reduction in manufacturing cycle time through faster movement of materials and by reducing the distance through which the materials are moved. Reduction in manufacturing cycle time results in reduced work –in –progress inventory costs.

Improved working conditions and greater safety in movement of materials

Contribute to better quality by avoiding damage to products by inefficient handling

Increased storage capacity through better utilisation of storage areas

Higher productivity at lower manufacturing cost

Other Objectives

GOALS OF MATERIAL HANDLING

The primary goal is to reduce unit costs of production

Maintain or improve product quality, reduce damage of materials

Promote safety and improve working conditions

Promote increased use of facilities

Reduce tare weight (dead weight)

Control inventory

GOALS OF MATERIAL HANDLING

Promote productivitymaterial should flow in a straight line

use gravity! It is free power

move more material at one time

mechanize material handling

automate material handling

GOALS OF MATERIAL HANDLING

Material handling equipment includes:Transport Equipment: industrial trucks, Automated Guided vehicles (AGVs), monorails, conveyors, cranes and hoists.

Storage Systems: bulk storage, rack systems, shelving and bins, drawer storage, automated storage systems.

Unitizing Equipment: palletizers

Identification and Tracking systems

Scope of Material handling: o Manufacturingo Processingo Constructiono Miningo Powero Machine Toolso Truck buildingo Rail road car builderso Barge and Ship buildingo Aircraft

Importance of M H Efficient material handling is important to

manufacturing operations. Materials sent by vendors must be unloaded, moved through inspections and production operations to stores and finally to the shipping department.

These movements do not add value to the product but they do add value to the cost

Material handling is an integral part of any industrial activity. With growing business, a greater emphasis is laid on productivity, profitability as well as resource conservation and ecological preservation. Material handling plays a very crucial role in sustaining efficiency in financial and human resources.

• Material handling analysis is a subset of plant layout. Method study, plant layout and material handling are all part of the design of a production facility

• Material handling system and plant layout enhance effectiveness of each other.

• Efficient operation of appropriate material handling methods reduces costs and enables maximum capabilities to be derived from a given production facility

THE PLANNING PRINCIPLE

Large-scale material handling projects usually require a team approach.

Material handling planning considers every move, every storage need, and any delay in order to minimize production costs.

The plan should reflect the strategic objectives of the organization as well as the more immediate needs.

THE SYSTEMS PRINCIPLE

MH and storage activities should be fully integrated to form a coordinated, operational system that spans receiving, inspection, storage, production, assembly…, shipping, and the handling of returns.Information flow and physical material flow should be integrated and treated as concurrent activities.

Methods should be provided for easily identifying materials and products, for determining their location and status within facilities and within the supply chain.

SIMPLIFICATION PRINCIPLEsimplify handling by reducing,

eliminating, or combining unnecessary movement and/or equipment.

Four questions to ask to simplify any job:

Can this job be eliminated?

If we can’t eliminate, can we combine movements to reduce cost? (unit load concept)

If we can’t eliminate or combine, can we rearrange the operations to reduce the travel distance?

If we can’t do any of the above, can we simplify?

GRAVITY PRINCIPLEUtilize gravity to move material

whenever practical.

SPACE UTILIZATION PRINCIPLE

The better we use our building cube, the less space we need to buy or rent.

Racks, mezzanines, and overhead conveyors are a few examples that promote this goal.

UNIT LOAD PRINCIPLEUnit loads should be appropriately sized and configured at each stage of the supply chain.

The most common unit load is the palletcardboard palletsplastic palletswooden palletssteel skids

AUTOMATION PRINCIPLE

MH operations should be mechanized and/or automated where feasible to improve operational efficiency, increase responsiveness, improve consistency and predictability, decrease operating costs.

THE STANDARDIZATION

PRINCIPLEstandardize handling methods as well as types and sizes of handling equipment

too many sizes and brands of equipment results in higher operational cost.

A fewer sizes of carton will simplify the storage.

EQUIPMENT SELECTION PRINCIPLE

Why? What? Where? When? How? Who?

If we answer these questions about each move, the solution will become evident.

THE MAINTENANCE PRINCIPLE

Plan for preventive maintenance and scheduled repairs of all handling equipment.

Pallets and storage facilities need repair too.

THE DEAD WEIGHT PRINCIPLE

Try to reduce the ratio of equipment weight to product weight. Don’t buy equipment that is bigger than necessary.

Reduce tare weight and save money.

THE CAPACITY PRINCIPLE use handling equipment to help

achieve desired production capacity

i.e. material handling equipment can help to maximize production equipment utilization.
