6.7 SAFETY BRAKE
The Gantry safety brake stops the Gantry rapidly when an E-stop condition occurs. The brake is applied by
a spring and is held in the released position by air pressure provided through the Brake Valve. An E-stop
condition causes the air pressure in the Brake chamber to be released through the Brake Valve. Releasing
the air pressure allows the spring in the chamber to rapidly apply the brake. This brake is meant for
emergency use only and is not meant to be used for normal stopping. A properly maintained Safety Brake
will stop the Gantry very quickly in an emergency. The Manual screen has a recorder which displays the
Gantry stopping distance for each Emergency stop system actuation. A properly operating brake system
will stop the Gantry in less than 20 inches from full speed. A stopping distance longer than 20 inches
indicates a problem with the brake system and presents a safety hazard. A screen warning will appear
when this happens. It is very important to identify and repair the cause of the problem immediately to
prevent injury or death.
