• Installation/Operator Manuals
The MicroGuard® TEREX RCI 510 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. At approach to overload, the system warns by
means of audible and visual alarms. The system can be configured to cause function kick-
out by sending a signal to function disconnect solenoids.
DISPLAY
The operator is provided with a continuous display of:
• Rated Load
• Actual Load
• Bar Graph showing Percentage of Rated Load
• Radius of the Load
• Boom Angle
• Main Boom Length
• Working Area
• Crane Configuration
On-screen messages provide the operator with visual warnings of conditions that occur
during operation of the system.
BOOM ANGLE SENSOR
Boom angle is measured by means of a highaccuracy potentiometer/pendulum assembly
that is damped to prevent overswing. It provides a voltage proportional to boom angle. The
boom angle sensor is mounted inside the cable extension reel assembly.
