  • Page 5: Introduction

    • Cables The Load Moment Area Protection (LMAP) system is intended to aid the crane operator by continuously monitoring the load and warning of an approach to an overload or two-block condition. Crane functions are monitored by means of high accuracy sensors. The system continuously compares the load suspended below the boom head with the crane capacity chart stored in the computer memory.

  • Page 6: Extension Sensor

    On-screen messages provide the operator with visual warnings of conditions that occur during operation of the system. Extension Sensor The extension sensor provides an increasing voltage proportional to the extension of the boom. A cable attached to the boom head provides a low current electrical path for the ATB signal. Function Kick-Out Electrically operated solenoids disconnect the control lever functions for boom hoist lower, telescope out, and winch up whenever an overload or an ATB condition occurs.

    Setting the Work Area Alarm This alarm, when set properly, enables the operator to define a safe operating zone by setting only two points. This results in an enhanced work area and defines the exclusion zone area. The exclusion zone area can be visualized by connecting the two set points with a horizontal line and extending the line upwards to create a vertical plane or wall.
