Several manufacturers of remote controls for cranes installed in classified areas use radio controls to eliminate cables.
Wireless Crane controls are now becoming more common: the purpose is to give the operator more freedom to move around.
This also eliminates cables that restrict movement and can eventually breakdown or ware out.
Usually the hand held remote control is intrinsically safe, but the receiver is not.
To safely transmit and receive control transmissions, Solexy RX antenna coupler is installed into the Exd receiver housing.
This allows safe transmission of signals in zone 1 areas.
