Radio control offers multiple-transmitter crane operation

Terex Material Handling has launched the latest generation of its Demag Remote Control (DRC) radio control system for cranes with its new D3 line of units. The hand-held transmitters and receivers meet the requirements of the future EN 300 328 V 1.8.1 radio standard, which provides for interference-free coexistence between W-LAN and other radio applications in the 2.4-GHz ISM frequency range. The radio transmission system allows up to 40 radio systems to operate in close vicinity to each other without any interference or drop-outs.

The transmitters are designed for multiple-transmitter operation. Operators can log on up to three transmitters per crane and then quickly switch from one transmitter to another at the press of a button, without interrupting handling processes. Individual cranes can be handed over from one worker to another.

The adaptive radio transmission method automatically checks whether a given transmission channel is available and uses frequency hopping to prevent interference and manipulation.
