16000 HANGING MAX-ER® OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES

OPERATION
1. Block crawlers if required to raise boom from ground.
2. Install required amount of hanging counterweight.
3. Select the proper capacity chart in RCL working screen
(Figure 3-6
) to operate in MAX-ER mode.
4. Raise boom to desired angle within range given in swing
and travel specifications chart. Hanging counterweight
will rise off ground.
Do not raise boom above maximum angle given in swing
and travel specifications chart — hanging
counterweight will lower to ground.
5. Travel and swing as required to position crane for lift.
6. Position boom at required angle and hook onto load.
Hanging counterweight will lower to ground if boom is
raised above maximum angle for swing and travel (see
minimum boom capacity to swing and travel column of
capacity chart).
7. Slowly lift load. Depending on load and boom angle,
hanging counterweight will or will not lift off ground.
8. If hanging counterweight remains on ground and it is
necessary to swing or travel, lower boom to an angle
which lifts hanging counterweight clear of ground (see
Minimum Boom Capacity to Swing and Travel column of
capacity chart).
9. Once hanging counterweight is off ground, all crane
functions can be operated — load, boom, swing, travel
— to move and position load in new location.
Do not raise boom above maximum angle given on
capacity chart for swing and travel (see Minimum Boom
Capacity to Swing and Travel column of capacity chart).
Otherwise, hanging counterweight will lower to
ground.
Keep boom at lowest possible angle that maintains
clearance between hanging counterweight and ground.
Dynamic effects of traveling with load can cause
counterweight to contact ground if crane is traveled
with boom at a high angle.
10. Once load has been moved to new location, slowly lower
load into position.
Depending on boom angle, hanging counterweight may
lower to ground when load lands.
11. Unhook load.
12. If hanging counterweight remains off ground, crane can
be swung and traveled as required to reposition crane
for next lift.
Position boom at desired angle within range given in
swing and travel specifications chart. Do not raise boom
above maximum angle given on chart — hanging
counterweight will lower to ground.
13. If hanging counterweight lowers to ground when load is
landed, lower boom until counterweight lifts off ground
and go to step 14.
If boom cannot be lowered or if hanging counterweight
does not rise when boom is lowered, perform one of the
following procedures:
REMOVE HANGING COUNTERWEIGHT BOXES:
a. Raise boom to an angle for which a capacity is
shown in desired column of capacity chart.
b. STOP ENGINE. This step must be performed so
counterweight assembly does not rise as boxes
are removed.
c. Remove required number of boxes (equal amount
from both sides of tray) with an assist crane.
d. Start engine. Hanging counterweight will rise off
ground.
DISCONNECT BEAM FROM COUNTERWEIGHT —
(beam remains connected to crane) this will allow you to
operate from 0 lb (0 kg) column of capacity chart. For
instructions, see Disconnect Beam from Counterweight
– SEQUENCE 1 in Section 4 of this manual.
DISCONNECT HANGING COUNTERWEIGHT FROM
CRANE — this will allow you to operate from “mast only”
capacity chart. For instructions, see Disconnect Beam
from Crane – SEQUENCE 2 in Section 4 of this manual.
14. Position boom at desired angle within range given in
swing and travel specifications chart and travel and
swing as required to reposition crane.
15. If necessary for next lift or to lower boom to ground,
perform one of the following procedures:
INSTALL HANGING COUNTERWEIGHT BOXES:
a. STOP ENGINE. This step must be performed so
counterweight assembly does not rise as boxes
are removed.
b. Install required number of boxes (equal amount
from both sides of tray) with an assist crane.
c. Start engine.
d. Po
sition boom at desired angle within range given in
swing and travel specifications chart. Hanging
counterweight will rise off ground. Do not raise
boom above maximum angle given on chart —
counterweight will lower to ground.
CONNECT BEAM TO COUNTERWEIGHT — For
instructions, see Connect Beam to Counterweight –
SEQUENCE 1 in Section 4 of this manual.
