Multi Purpose Bridge ECE Project

Aim: The Multi Purpose Bridge designed here can be used for crossing the road; the same bridge constructed with crane mechanism at its bottom side also can be used as crane for lifting & carrying the packages across the road without disturbing the traffic.

WORKING: The Multi Purpose Bridge is constructed with metal sheets & the crane mechanism is designed with two DC motors. The mechanical transition section is aimed to lift the luggage up to certain height & it is carried to the other side of the road.

The crane is controlled through wireless operates, & the wireless network is designed with RF modules operates at 433MHz, so that the operator can sit at one place & can handle the crane.

The control circuit is designed with 89C51, & motors are driven through ‘H’ bridge. The system is quite useful for big cities.
