OPERATION AND FUNCTION

This section of the manual will provide the operator with information on the location and
operation of the displays, push buttons, lights and selector switches of the "H(L)AP" family of
Indicating Systems.
The "H(L)AP" family of Indicating Systems is designed to provide an audible and visual warning
of an IMMINENT TWO-BLOCK condition and analog indication of MAIN BOOM ANGLE with
ANGLE PRESET and MAIN BOOM LENGTH. The "H(L)AP" family of Indicating Systems can
actuate an optional crane function shut off system.
This manual covers both the HAP and HLAP Indicator systems. The panel shown below is the
HLAP Indicator. The HAP panel is similar in design. Buttons 5, LENGTH, and 6, ANGLE, are
not required for the HAP indicator.
1. ANALOG METER
The analog meter is used to display angle and length indication.
BOOM ANGLE
The actual boom angle, the angle between the longitudal centerline of the boom
base section and horizontal plane, is displayed in 2° increments.
