R147 Anti Two Block

R147 ATB Crane Blocking Equipment

R147 ATB

Wireless Anti-Two-Block Warning System

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.
