DESCRIPTION
The PAT Radio Anti Two Block, RATB, uses state-of-the-art technology. The radio communication
electronics were designed cooperatively between PAT and OMNEX controls. OMNEX was chosen
because of its established name and proven experience with wireless communications in the
construction equipment industry. Our system transmits an OK signal ~ every two seconds on up to
three separate channels. This is to ensure accurate and consistent reception of data and to reduce the
possibility of unnoticed failure. The separate channels greatly reduce the probability of failure due to
external interferences.
Unique, serialized transmitter identifiers are used to ensure proper operation even though other
cranes are in the area.
cranes are in the area.
The PAT RATB is easily configured to communicate with up to two transmitters. Simply by pressing
and holding the “ID” button for five seconds, the receiver can sense the transmitters being used and
configure the receiver to listen to only those transmitters. There are no numbers, ID’s or codes to
remember or write down.

The PAT RATB works like our normal Anti-Two-Block. It alerts to an impending two-block condition.
This alert can come in the form of an audible alarm and visual LED or with the optional function
lockout if the crane is so equipped.

The PAT RATB transmitter is modular by design, containing three separate parts, the transmitter, the
switch and the battery housing. It was designed so these individual components can be replaced
easily and separately.

The receiver is mounted into a receiver box, which is water-tight when submerged in up to three feet
of water. The receiver box provides the following indications: Power (status), LINK, Low Battery, and

If battery saving measures are used, the battery life will be greater than one year or up to two years,
even with transmitting every two seconds. Several power saving methods are incorporated into the
design of the electronics as well as the other hardware.
