Rayco - Wylie Systems

System Description:
 The R147 provides an audio and visual alarm when the hook reaches the maximum safe height to the boom tip.  The display transmits wireless to the tip mounted anti-two-block (ATB) switch.  A second switch and weight can be added to monitor the main and auxiliary hoist on the same display.  The switches are interchangeable, so they can easily be moved from one crane to another.  The display has an internal relay that can be integrated with a function lock out system.

The system has several built in safety features.  The internal antenna in the switch and display are a unique Rayco / Wylie design that provides less failures than systems with external antenna.  Also the display will default to alarm and warn the operator if there is any interference with the signal to the A2B switch.  In addition the display will warn the operator when the battery is getting low.  You will normally have at least a two week warning.
