DESIGN AND IMPLEMENTATION OF A CONTROL TOWER CRANE BY IR REMOTE CONTROL

The main objective of the project is to design robust, fast, and practical controllers for tower cranes to transfer loads from point to point in a short time as fast as possible and at the same time, keep the load swing small during the transfer process and completely eliminate it at the load destination. Moreover variations of the system parameters, such as the load weight are taken into account.A tower crane is one of the major items of equipment used in the construction of high-rise buildings. However, crane operators do not receive adequate information, such as the target space conditions and the material being lifted, to control the crane. This limitation degrades productivity and safety. This study describes a prototype of a tower crane equipped with wireless control (IR remote control) technology. With these advanced technologies, the tower crane can provide the crane operator with an enhanced view of the work space and various other functions providing up-to-date material status. The tower crane can also provide faster information flow with greater accuracy and improved driving efficiency. The tower crane was used to test its performance. The main objective of the project is to design robust, fast, and practical controllers for tower cranes to transfer loads from point to point in a short time as fast as possible and at the same time, keep the load swing small during the transfer process and completely eliminate it at the load destination. Moreover variations of the system parameters, such as the load weight are taken into account. The results confirmed considerable improvement in operational speed and significantly enhanced performance in workplace safety and communication efficiency
