problem can be solved if a trolley can lift loads while
traveling through stairs.

transportation of the loads over the stair. The vehicle is
designed in such a way that it has three wheels on each
side. They are set in triangular pattern. This project

creates vibration and the vehicle would be unstable. In
the present design, the wheel frame was made curve so
that the front surface of the arm could not collide with
the edge of the stair.[7]
PrajanPradipGondole, et. al.: in April-2015: have
concluded that the stair-climbing hand truck is designed
to reduce liability rather than increase it. Conventional
hand trucks work well on flat ground, but their
usefulness decreases when It becomes necessary to move
an object over an irregular surface. Package
deliverymen, for example, often find it necessary to drag
loaded hand trucks up short flights of stairs just to reach
the front door of a building. The entire purpose of using
a conventional hand truck is to avoid having to lift and
carry heavy objects around.[10]

sides are used in the tri lobed frame. The wheel assembly
is rotated by a gear- motor mechanism where a DC gear
motor is used to provide the necessary power for rotation
and a pinion gear mesh is used for reducing the rotating
speed of the wheel. The motor is connected to a lead
acid battery of similar ratings and they are in turn
connected to DPDT switch[9].

NEW CONCEPT:
It move on rough and stair automatically. In this
system task perform fast and efficient. It not required
human effort. It is time saving concept. Less risk of

CONCLUSION

In this paper we implement the material handling with

less human efforts in minimum time without damaging
the material while transportation. In this concept we find
out the automatic trolley and it operate automatically.
concept of stair climber material handling system which
provide the service to reduce the human efforts in many
fields like offices, colleges and industries for handling
material on stair case. It provide service to replace man
in dangerous environment to transfer material on stairs
and flat surface, like underground storage godownwhere
oxygen is in less amount.
