The research results of the possibility of increasing the productivity of the bridge crane through the introduction of hardware and software base Arduino in its control system are given in the article. The indexes of technical productivity of batch operation lift and carry machines of periodic action are analyzed and the working cycle duration has been shortened. Several cases (successive execution –each subsequent movement only begins after the end of the previous one; partial combination – combine only a few separate movements are combined; full alignment – all crane movements with the load are combined in time) is considered. In this article, based on the results of the analysis, the control of the load-lifting machine was built due to of the introduction of telecommunication systems and technologies, namely the use of microcontrollers with the implementation of control using wired (Ethernet) or wireless (Bluetooth, Wi-Fi) network. Because there is the need to increase the productivity of lift and carry machines, to improve the working conditions of personnel, to improve the reliability and durability of machine elements, causes the creation of new, more advanced systems of machine management and partial or complete automation of their work. Safety in the production will increase significantly with this technology, as it will be possible to implement protection against overload, excess speed, rocking, moving cargo to areas where people are located and so on the results of the article are shown. Crane management can be done either from the operator's cab, directly controlled by the controller, or remotely, by transmitting signals over wired (Ethernet) or wireless (Bluetooth, Wi-Fi) networks.
