Introduction
System Components
• LMAP Display Unit
• LMAP Computer Unit
• Pressure Transducers
• Extension Reel with length and angle sensors
• Anti Two-Block (ATB) switches
• 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. 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.

Anti Two Block (ATB)

A switch monitors the approach of the hookblock or overhaul ball to the boom head. The switch is
held in the normal position until the hookblock or overhaul ball raises a weight that is mounted around
the hoist rope. When the weight is raised, it causes the switch to operate. The resultant signal is
sent to the computer via the extension reel causing the ATB alarm to operate and function kick-out to
occur.

Area Alarm
When set, this alarm permits the operator to define the operating zone by only two set points. The
use of this method of setting results in a greatly enhanced working area, and also clearly defines the
operating zone.

Boom Angle Sensor

Boom angle is measured by means of a high accuracy potentiometer, a magnetically dampened
pendulum to prevent erratic voltage changes. It provides a voltage proportional to boom angle. The
boom angle sensor is mounted inside the cable extension reel assembly.

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
1
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.

Pressure Transducers
Two pressure transducers measure the pressure in the boom hoist cylinder. The resultant Total
Moment signal is processed to provide a continuous display of the load suspended below the point of
lift.

Operator Alarms
These alarms, when properly set by the operator, define the operating range. This is achieved by
means of minimum and maximum angle, maximum height, and/or maximum length. These alarms
can be programmed for each job site and allow the operator to work in a defined area.

1. Overload Warning – This red LED illuminates when you reach or exceed 100% of rated
capacity. It is accompanied by solid tone alarm and when maximum rated capacity is exceeded
will result in boom function lockout.
2. Approaching Overload Warning – This amber LED Illuminates when you reach or exceed 90%
Rated Capacity. It will be accompanied by a beeping alarm.
3. Parts of Line – Displays current number of parts of line in use.
4. Load on Hook – Displays the entire hook load weight under the head of the boom, including
cable, load block, load handling equipment, and weight of load hanging on hook.
5. Percent of Rated Capacity Meter - Shows the load as a percentage of rated capacity. As the
load increases, the meter level increases to represent the percentage of the rated capacity of
the crane.
6. Rated Capacity – Displays the rated capacity in the current configuration based on the crane
load capacity chart.
7. ATB Warning – Warns of a potential two-block condition with flashing LED and audible alarm.
8. Boom Length – Displays the current boom length in feet and tenths of a foot.
9. Boom Angle – Displays the current boom angle in degrees and tenths of a degree.
10. Load Radius – Displays the load radius from centerline of rotation.

second winch (for models euipped with auxiliary winch only).
18. Alarm Cancel – Disables audible alarm. Holding down this key overrides function kick-out.
19. Test Button – Press and hold the test button to initiate a system self test and run diagnostics.
20. Operator Alarm/Set – Enables operator alarms. When an alarm has been set, the LED above
this button will illuminate yellow.
mWarning
You must use the Crane Setup Mode to correctly set the LMAP System for
proper operation. The LMAP System Setup must match the actual configuration
of the crane so that it will indicate the correct hook load and lifting capacity
of the crane.

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. When the end of the boom passes through this plane,
the red warning lamp will illuminate and the display will show the message “EXCLUSION ZONE”.

Working Distance is the time it would take to react to an alarm, and for the

to set points that ensure that the Boom, Attachments, Hook Load, and Rigging,
maintain a Safe Working Distance from the obstacle. Avoid positioning the
Boom, Attachment, Load, and Rigging, in the Exclusion Zone when moving to Set
