3 SYSTEM DESCRIPTION

The PAT EI 65 System consists of an operating console with central micro processor unit,
length/angle sensor, force transducers and anti-two block switches.
Boom length and boom angle are registered by the length/angle sensor, mounted inside the
cable reel which is mounted on the boom. The boom length is measured by the cable reel
cable that also serves as an electrical conductor for the anti-two block switches.
The crane load is measured by running line tensiometers attached to the upper side of the
boom.
3.1 System Function
After ignition of the engine, the system starts with an automatic test of all lamps, the audible
alarm and the complete system.
After the system has passed through the system test without errors, the system will request
the operator to confirm the boom and jib configuration data. This allows the operator to
compare the system configuration with the actual crane configuration. (see Section 4.1).
After the operator confirms the system configuration, the console will indicate, on the display
(13), the actual load, tip height, boom length, boom angle, and radius.
