Electronic control card for transmission of mobile load crane type KRUPP

Abstract

The design, modification and control of machinery and industrial equipment plays a very important role in any company, where machinery and / or equipment is found which are out of operation due to the lack of an electrical / electronic control part which possibly By the model of the machinery and / or equipment is no longer manufactured or is difficult to achieve. This causes economic losses due to having the machinery out of operation. This article presents a proposal to replace the computer corresponding to the operation of the transmission of a mobile telescopic load crane, which consists of using an Arduino programming board for the control part and to obtain the necessary logical sequence of the different transmission speeds, power electronics (power transistors) were used for the power stage through which the necessary voltage and current levels are obtained to which the electrovalves corresponding to the different speeds of the transmission operate. As shown in the content of the work control is very accessible, so, it could be implemented in a sustainable way in other vehicles that have an automatic transmission with changes in speeds through electrovalves.
