3-10

OPERATING PRECAUTIONS
1. Manitowoc assumes that a qualified crane operator will
be used to operate the 16000 with hanging MAX-ER.
- Read and become thoroughly familiar with
Operating Controls and Procedures section of
Crane Operator Manuals.
- If equipped with a luffing jib, also read and become
thoroughly familiar with instructions in Luffing Jib
Operator Manual and in Luffing Jib Capacity Charts.
- Read and become thoroughly familiar with
instructions in this section and in hanging MAX-ER
capacity charts before operating crane.
2. Read and comply with instructions in the following
hanging MAX-ER capacity charts. Do not operate
beyond limits given:
- Liftcrane Boom Capacities Chart
- Liftcrane Boom with Mast Capacities Chart
- Liftcrane Luffing Jib Capacities Chart
- Counterweight Arrangements Chart
- Swing and Travel Specifications Chart
The charts are located in the Hanging MAX-ER Operator
Information Manual in the crane cab or in the Hanging
MAX-ER Capacity Chart Manual supplied to the crane
owner.
3. Make sure proper counterweight is installed — both on
the crane and on the hanging counterweight tray.
4. Make sure hanging counterweight assembly is at proper
operating position as specified in hanging MAX-ER
capacity chart.
5. Make sure crawlers are blocked and proper amount of
hanging counterweight is installed — as specified in
hanging MAX-ER capacity chart — before raising and
lowering boom from and to ground.
6. Make sure load sensing pin and all sensors are properly
calibrated; otherwise, hanging counterweight assembly
will not operate properly. See Section 6 for calibration
procedures.
7. Make sure all operating limits — block-up, boom and jib
stops, boom and jib angle indicators, and Rated
Capacity Indicator/Limiter (RCL) — are installed and
operating properly. See Section 6 of this manual for
adjustment procedures. See separate Rated Capacity
Indicator/Limiter Manual for operation and calibration of
the RCL.
8. Turn on hanging MAX-ER operating mode for operation
with hanging counterweight assembly installed (see
MAX-ER Operating Mode topic in this section).
- Hanging counterweight assembly will not rise
and lower automatically if hanging MAX-ER
mode is not selected.
- Hanging counterweight assembly remains in its last
position — up or down — if MAX-ER operating
mode or engine is turned off during operation.
9. Access information screen on main display to monitor
MAX-ER operating conditions.
10. Operate only with crane on a firm surface that is
uniformly supporting:
- With load, grade must not exceed 1% in any
direction — 1 ft in 100 ft (0,3 m in 30 m)
- Without load, see Swing and Travel Specifications
Chart
- Make sure foundation under crane and under
hanging counterweight tray is at the same level.
Mast can buckle if hanging counterweight is
lowered below grade.
11. When swinging and traveling with load, do not raise
boom above maximum angle for swing and travel given
in Capacity Chart (see Minimum Boom Capacity to
Swing and Travel column of chart); otherwise, hanging
counterweight will lower onto foundation.
12. Do not operate crane, to include raising boom and luffing
jib from ground level, if wind exceeds limits given in
MAX-ER Capacity Charts. Contact your local weather
station for wind velocity.
13. Be aware of increased tail swing with hanging
counterweight assembly installed. Counterweight
assembly can strike objects or personnel in area of
travel and swing paths.
14. Warn all personnel to stand well clear of crane. Hanging
counterweight assembly rises and lowers automatically
without warn
ing — it can strike or land on personnel.
15. Provide a signal person for all crane operations.
Have signal person watch for clearance under
counterweight tray while swinging and traveling. Do not
allow hanging counterweight assembly to strike
obstructions.
DANGER
Observe the following operating precautions to prevent
tipping or structural failure of attachment.
