SYSTEM DESCRIPTION:
The PAT Length-Angle-Radius-Load Indicator System EI65 has been designed to
provide the crane operator with the essential information required to
enable the machine to be used within its design parameters. The EI65 System
indicates the length and angle of the boom, tip height, working radius and
the total weight being lifted by the crane. Using the various sensors and
the limits set by the operator, the EI65 System warns the crane operator of
certain approaching hazardous conditions which could occur during the
operation of his crane.
WARNING
Always refer to operational instructions and load charts provided by the crane
manufacturer for specific crane operation and load limits.
