Abstract:
Crane is a hoisting machine which used for lifting heavy loads and transferring them
from one place to another.
Three-dimensions crane has a wide usage, where 90% of industry application used
this type machines, however, as soon as you start to think in solving the problems that
faces a worker in a factory, you should consider the work condition so as to suggest
optimum solutions for better usage of the crane. That is, the manual crane controlled
by heavy cable has many disadvantages to faces the operator and the mechanical
process in the factory. Remote control idea is better than traditional crane control and
more efficient.
On the other hand, the crane design is hard and should be accurate to realize a
powerful, cheaper and reliable crane according to different loads. Also how to make
electrical wireless interface between crane motors and remote electronic circuits.
In this project we will design 3-D crane which is control by using programmable logic
control technique (PLC). Here we will build remote control circuits, power circuits of
three motors which are used to move the load up and down and the mechanical parts
which carry the motors and the load. but after building these part of project we see
that the remote control circuit dose not work as will as to control from long distance
because of the limitation of the hardware device . Also, the motor must run in
different speed , whereas , in this project the motor run in one speed .
