The 4 function Wireless Radio Remote Controls allow boom trucks and cranes to be operated from a roof-top, within a man basket, or at the lift / set area for maximum flexibility, visability, and safety. No longer is the operator teathered to the crane or boom truck by the controls, now he's part of the rigging crew. Get the safest view of the pick point by actually being there. Go Wireless! * This Remote Kit is “plug and play” on most current models Terex Boom Truck. Installation on older models, and non Terex models may require additional hardware/programming. Call a parts representative with your crane S/N prior to ordering.
