Remote control of three dimensions crane

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 .
