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.
