FOREWORD
The purpose of this manual is to provide the installer and technician with information on the
proper installation and set-up of the KRÜGER “H(L)AP” family of Indicator Systems.
The H(L)AP family of Indicating Systems is designed to provide an audible and visual warning of
an IMMINENT TWO-BLOCK condition with an analog display of MAIN BOOM LENGTH and
MAIN BOOM ANGLE. The H(L)AP family of Indicating Systems can actuate an optional crane
functionshutoffsystem.
WARNING
DO NOT CONSIDER THIS SYSTEM A SUBSTITUTE FOR GOOD
JUDGEMENT, EXPERIENCE AND ACCEPTED SAFE CRANE
OPERATIONAL PRACTICES.
THE CONTENTS OF THIS HANDBOOK AND THE CRANE
MANUFACTURERS HANDBOOKS SHOULD BE READ AND
UNDERSTOOD BEFORE ATTEMPTING TO OPERATE THE
CRANE.
NOTE
This system utilizes a series of electrical and mechanical components and
cannot be 100% fail safe.
Thissystem shouldonly beserviced byqualified individuals,either PAT-KRUEGERCorporation,
Inc. service technicians or those who have received special training from Krüger GmbH & Co.
KG. or their authorized representatives.
Toavoid damageand loss of warranty consideration,we recommend repair only be attempted

If conduit is not used, secure the cable to the boom structure using stand offs and tie
wraps.
CAUTION
INSTALL THE CABLE INTO THE RECEPTACLE WITH THE CABLE
ENTERING FROM THE LOWEST POINT OF THE RECEPTACLE
WITH THE BOOM IN ITS NORMAL OPERATING POSITION.
2. Removethecablereelcover. Removethenutandrubbergrommetfromthecentershaft.
Route cable through the mounting bracket and into hole in the cable reel center shaft.
Replacetherubber grommet and nut,tightennut. Install the cable reelintothe mounting
bracket and tighten the bolt in the mounting bracket to lock the cable reel in place.
CAUTION
DO NOT LOOSEN SPRING LOCK NUTS,
AS CABLE REEL SPRING IS UNDER
TENSION, WHEN SHIPPED.
INSTALL EITHER THE 5 CONDUCTOR
CABLE OR 10 CONDUCTOR CABLE
WITH A DRIP LOOP TO REDUCE THE
POSSIBILITY OF WATER ENTERING THE
CABLE REEL HOUSING.
3. Unwrap sufficient cable from the cable reel to reach the strain relief anchor on the boom
head.
NOTE
Take care to keep any twists out of the cable reel cable.
4. Route the cable through the roller guides and attach the strain relief assembly to the
anchorbracketontheboomhead.
NOTE
Do not put a twist in the cable reel cable between the reel and strain relief
anchor. Twisted cable will result in accelerated wear.
5. Ifa 6 PinReceptacle is installed atthe boom head,pull the cablereel cable throughthe
P clamps on the receptacle and into the bottom of the receptacle. Wire as shown on the

9. Install either the 5 conductor or 10 conductor cable in
the Boom Pivot receptacle. Wire as described in the
wiringdiagramincludedwiththispublication.
10. Make up either a 6 Pin or 10 Pin Plug with either 5

longenough to berouted along themachine structure
to the Control Panel mounted in the crane cab.
NOTE
Route cable to ensure that cable is not crimped
or can be stepped on in the normal course of
machineoperation.
11. Secure the cable in position with stand offs and tie wraps, as needed.
12. Install cable in panel and wire to terminal strips in the panel. Refer to the wiring diagram
includedwiththispublication.
13. Install a piece of 2 conductor Olflex cable from panel to the power source of the crane.
Connect the power side to the power source. The preferred connection is the run side of
theignition keyswitch. Connect theground wireto a cleaned ground lug on the machine
structure.

1. Bring the boom down to zero degrees (level). Measure with an angle finder to insure that
the boom is at zero degrees.
2. Loosen the cable reel mounting bolt and
gentlyturn thereel until the angle

offthestop(seediagram).
3. Apply power to the system and select
the angle indication (HLAP ONLY). The
meter should indicate zero degrees on
thepanelinthecab.
4. If the indication is not correct, gently
rotate the cable reel until the reading is
correctandtightenthecablereelmounting

Theanglevoltageshouldbemeasuredat
this time. Using a volt meter place the
positive lead on terminal #5 on the 6 pin
terminal strip in the cable reel and the
negativeleadon terminal#4. Thevoltage
should be in a range of 0.995 to 1.005 volts DC.
If the voltage is not in this range, loosen but do not remove the three screws that hold the
Angle Pot in the mounting bracket. Rotate the angle pot to bring the voltage into the
allowablerangeandtightenthescrews.
If this is an HAP system continue at step 7.
5. With the boom fully retracted, carefully loosen the spring lock nuts on the back side of the

and the negative lead on terminal #1. the voltage should be in a range of 0.995 to 1.005
voltsDC. Ifthevoltage needs adjustment, rotatethearmon the back of thelengthpotin

9. Checkseveralboomanglesbetweenzeroandmaximumtoverifythesystem’soperation.
10. Tocheck the lowangle preset warning. With aboom angle greaterthan 10 degrees,set the
low angle preset to 10 degrees. Boom down until the light and horn come on. This must
occur between 10 and 12 degrees. If the light and horn come on too late or too early,
removethe black coveron the knob,loosen the screw inthe middle ofthe knob andadjust
the knob until it is correct. Tighten the screw and replace the cover.
11. To check the high angle preset warning. Turn the low angle knob to zero degrees and
boom down below 10 degrees. Turn the high angle preset knob to 10 degrees. Boom up
until the light and horn come on. This must occur between 8 and 10 degrees. In the light
and horn come on too late or too early, remove the black cover on the knob, loosen the

If this is an HAP system continue at step 17.
14. Check and adjust the length indication (HLAP ONLY). Push the L button to select length
indication. The length should read the fully retracted boom length. If it does not, adjust
pot R16 (L) Offset in the panel until it is correct.
15. Fullyextendtheboom(includinganymanualorpinnedsection). Checkthelengthindication
against the actual boom length. If it is incorrect, adjust potR12 (L) Maxin the panel until
the correct length is indicated.
16. Fully retract the boom and check the length indication. If necessary re-adjust potR16(L)
Offsetin the panel. Calibration of the retracted and extended boom lengths interact,
which may make it necessary to repeat these steps for proper length indication.
17. Complete installation of Crane function shut off system, if required.
18. Create a Two-Block condition by lifting the counterweight at the boom head. Check that
thelight and horncome on. If equipped witha Crane functionshut off systemthe following

19. Lower the counterweight to verify that the light and horn go off and all crane functions
returntonormaloperation.
18. The machine is ready for operation.

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.

BOOM LENGTH
The Main Boom Length is displayed on this meter. Various scales are used
depending on the Boom Length.
2. UPPER BOOM ANGLE PRE-SET
The Upper boom angle limit is set by rotating the selector switch. This setting
determines the maximum boom angle for crane operation.

7. A-2-B WARNING LIGHT
If the A-2-B circuit is "open" the warning light “A- 2-B” comes on and a shut off relay
is utilized to stop specific crane functions, if the crane is equipped with a crane
function shut-off system. The shut off function can be by-passed using the
momentary “By Pass” key switch in the panel. If the A-2-B switch is activated and
the “By Pass” key switch is used, the A-2-B warning light will remain on until the
pending 2-Block condition ceases.

WARNING
THE BYPASS KEY SWITCH SHOULD BE USED WITH
DISCRETION, AS UNWARRANTED USE OF IT TO OVERRIDE
THE CRANE FUNCTION SHUT OFF SYSTEM COULD RESULT
IN LOSS OF LIFE, DESTRUCTION OF PROPERTY AND/OR
IRREPARABLE DAMAGE TO THE CRANE. SOUND JUDGEMENT
