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 1800’s 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 truck
Transmission System
Steering System
Hydraulic System
Electrical System
FORKLIFT PRINCIPLES
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.
THE LEVER
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 truck’s 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 three-
point 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
