R147 Anti Two Block

The R147 wireless ATB warning system provides an audio and visual alarm when the hook reaches the maximum safe height. The display transmits wirelessly to the tip-mounted anti-two-block (ATB) switch eliminating the need for a cable reel. The display runs on 12V or 24V and has an internal relay for use with lock-out valves (optional accessory). The internal antenna in the switch and display are a unique Rayco - Wylie design that eliminates the most common failure in systems with external antennas. Our crane blocking equipment will fit telescopic and lattice boom cranes.
