Digital fail-safe radio control systems offer the safest and most rational solution for cranes and shuntig locomotives. Flexible use of the equipment and mobility mean the operator can alwais be where the action is- whether using a large crane to position a heavy machine component with absolute precision or assembling good trains. TEC radio control system applications offer a high degree of reability and therefore a high utilisation factor. Our applications offer the facility of controlling several crane, locomotives or other system simultaneously on a single carrier frequency in complete safety. Radio data trasmission is the heart of automation, for example cheching weights when loading items far away or transmission of process information. TEC radio data transmission not only results in a considerable reduction in costs but also allows more rapid and accurate recording of data.
