Energy-saving remote control system for tower cranes

Improving the safety and economic efficiency of lifting equipment and, in particular, tower cranes remains an important task in the modern world. Ukrainian University has developed a control system for tower cranes, which reduces the level of their energy consumption and brings their work in line with modern safety standards. The system uses installed programmable energy-saving drives, equipped with the necessary sensors with the ability to work in "blind" areas and provides a reduction in the installed power of tower crane motors and optimal control. The proposed system uses the patterns of changes in the dynamic and energy characteristics of the operation of an asynchronous motor in all parts of the operating cycle: acceleration, uniform motion, and deceleration. The trajectory of motion and kinematic characteristics can be calculated using methods of the theory of optimal control. The system can be used in construction, crane building, mechanical engineering, industry in industrial control systems. The university is interested in introducing the system outside of Ukraine and is looking for owners of operating tower cranes, as well as manufacturers of lifting equipment who are interested in improving the efficiency of their equipment. The desired form of cooperation is a commercial agency agreement with technical assistance.
