MATERIAL HANDLING

Material Handling is the movement, storage, control and protection of materials, goods and products

Material handling equipment is used to increase throughput, control costs, and maximize productivity.

Everything we eat or wear, and we use has, at some stage, been stored and handled by materials handling equipment.

FORKLIFT TRUCKS

FORKLIFT TRUCK - A MHE or a Powered industrial truck used to lift and transport materials.

They are a prime part of any industry. They are different from other MHEs. They have rear wheel steering.

HISTORY

First used in 1800s as SACK TRUCKS. Powered truck came into being in the early 20th century. These trucks became popular due to the shortage of labour in WW-I.

CLARK first gave the counter balanced truck in 1917, YALE produced the first electric truck in 1925.

Post WW-II, Warehouses needed more maneuverable forklift trucks with higher demands.

Soon many types of trucks came into existence to meet these demands.

WORKING

Working can be understood through the four main systems of a forklift trucky Transmission System y Steering System y Hydraulic System y Electrical System

FORKLIFT PRINCIPLESTHE LEVER

Lever: It is one of the simplest mechanical devices. However, a lever by itself is not effective. It must have something on to pivot. This pivot is called a fulcrum.

Law of Equilibrium: The effort multiplied by its distance from the fulcrum equals the load multiplied by its distance from the fulcrum. This law of equilibrium is true for all classes of levers.

CLASSES OF LEVERS

CENTRE OF GRAVITY

It is the point on an object at which all of the objects weight is concentrated. For symmetrical loads, the center of gravity is at the middle of the load.

FORKLIFT STABILITY

A forklift trucks ability to stay upright while it is in motion is its stability.

It is the most important aspect to avoid accidents.

The lateral stability of a truck changes depending on how high the load is lifted to.

The rated lift capacity is reduced at increased lifting height.

STABILITY TRIANGLE

Almost all counterbalanced powered industrial trucks have a threepoint suspension system.

The triangle formed between points A, B, and C is called the Stability Triangle.

The truck will not tip over as long as the center of gravity(C.G.) remains inside the triangle.

FUTURE PROSPECT

Logistics is growing very fast in India The new age hybrid engine driven forklift trucks have been already designed and developed in some parts of the world.

Bright careers prospects in this field in INDIA.

CONCLUSION

FORKLIFT TRUCKS play a major role in the industries. FORKLIFT TRUCKS aid the industries to attain high productivity and achieve cost optimization.

INDIA has a bright future in material handling. The knowledge about FORKLIFT TRUCKS is necessary. Thus my intention has been to provide you with the overview of the fundamentals of FORKLIFT TRUCKS
